Michael Pinsky: Pollution Pods | Somerset House
Each replicates nuanced polluted environments which contain varying levels of ozone, particulate matter, nitrogen dioxide, sulphur dioxide and carbon monoxide. London’s invisible, but deadly, output nitrogen is followed by New Delhi where the air is filled with a haze of airborne particles. It is estimated that the average Londoner, exposed to the current levels of pollution loses up to 16 months of their life, while for a resident of New Delhi, pollution could cut short the life of a resident by around 4 years.

London air pollution is poisoning my son, says campaigner | Environment | The Guardian
Smith said that he first became concerned about the air pollution crisis after his two youngest children – a daughter, 10 months, and Ely, now three – were born prematurely and “on the cusp” of being underweight. His daughter has since suffered serious respiratory problems, and now has medication and medical equipment to help her breathe.

Sitting at his kitchen table, Smith says his wife, a lawyer in central London, travelled to work as usual during both pregnancies, walking along a busy road to the tube. “You can’t attribute these things definitively to air pollution but the more you find out the more you realise the huge damage it is doing to our children’s health,” he said.

The family, who do not own a car, now carefully plan every journey. They avoid main roads, the rush hour and busy bus stops wherever possible. But it is not easy. “There is only so much you can do when in a big city like this. To a certain extent, we have got to accept now that we are doing great damage to our children’s long-term health simply by living here.”

Number of dirty diesels on road still growing, report shows | Environment | The Guardian
The number of dirty diesel vehicles pumping out toxic emissions on Europe’s streets is still rising three years after the Dieselgate scandal began, according to a new report. More than 7m such cars and vans remain on UK roads alone.

There were 29m diesel vehicles whose emissions on the road were significantly higher than official laboratory-based EU limits when the diesel scandal erupted in September 2015. But that has now risen by to 43m, according to analysis by the group Transport & Environment (T&E). France has the most dirty diesels on the road, with 8.7m, followed by Germany’s 8.2m and the UK’s 7.3m.

From Russian Winds to Cruise Ships: Exploring the Local Problems Driving the UK's Air Pollution Crisis | DeSmog UK
Earlier this year, the World Health Organisation found 47 UK towns and cities had either reached at or had gone beyond air pollution limits. The issue has been widely covered, with the NGOs, the press and opposition politicians quick to criticise government inaction.

The backdrop to all this is the ‘dieselgate’ scandal. As far back as 2015, car manufacturers including German giant VW were accused of cheating emissions tests, with their vehicles found to be much dirtier than the companies suggested. Ever since, cars’ contribution to the UK’s poor air quality has come under deep scrutiny.

But it can’t just be cars, can it?

After three years, countless pages of analysis and enquiry and multiple court cases, policymakers must finally be getting on top of the ‘car issue’, right? Surely, something else must be driving the country’s terrible air quality?

DeSmog UK spent six months trawling through local data and air quality reports to find places where air pollution wasn’t just a road traffic problem. There weren’t many.

The problem is that almost all roads are clogged up by commuter and industrial traffic.

Nonetheless, our detailed analysis of hundreds of pages of local authority reports did throw up some examples of where local idiosyncrasies exacerbate the car problem.

10 Monkeys and a Beetle: Inside VW’s Campaign for ‘Clean Diesel’ - The New York Times
German automakers had financed the experiment in an attempt to prove that diesel vehicles with the latest technology were cleaner than the smoky models of old. But the American scientists conducting the test were unaware of one critical fact: The Beetle provided by Volkswagen had been rigged to produce pollution levels that were far less harmful in the lab than they were on the road.

The results were being deliberately manipulated.

The Albuquerque monkey research, which has not been previously reported, is a new dimension in a global emissions scandal that has already forced Volkswagen to plead guilty to federal fraud and conspiracy charges in the United States and to pay more than $26 billion in fines.

After their attacks on climate science, industrial lobbyists target the scientific evidence on air pollution - Multinationals Observatory
Science under the influence

And obviously, there is the case of Michel Aubier. This eminent respiratory physician cruised the television studios downplaying the dangers of air pollution, only to later reveal that he was also a paid consultant to Total (read our article). In 2012, Aubier published an Académie de médecine report—widely cited by industry—entitled “Impact sanitaire des particules diesel : entre mythe et réalité ?” (The health impacts of diesel particulates: between myth and reality?), that promoted the merits of particle filters. In 2015 he had also testified along the same lines to a senatorial enquiry, claiming that the number of cancers linked to pollution was "extremely few". On both occasions he neglected to mention his pecuniary involvement with a multinational corporation whose primary business is the sale of petrol and diesel. In July 2017 he received a suspended six-month prison sentence and a €50,000 fine for failing to declare this conflict of interest to the Senat when asked.

Après celle du climat, l’industrie et ses lobbyistes s’attaquent à la science de la pollution de l’air - Observatoire des multinationales
Après le climato-scepticisme, le dieselo-scepticisme ? « L’air moderne est un petit peu trop propre pour une santé optimale » ; « on ne peut pas faire de lien entre décès prématurés et ozone » ; « [si la pollution de l’air tue,] où sont les corps ? » ; « les experts ne sont pas d’accord entre eux quant à la réalité de l’impact sanitaire des particules fines » ; « la qualité de l’air n’a jamais été aussi bonne qu’aujourd’hui »… Telles sont quelques-unes des phrases que l’on a pu récemment glaner, de divers côtés, dans les médias ou les réseaux sociaux en France, aux États-Unis et ailleurs. Alors que des voix de plus en plus nombreuses s’élèvent pour dénoncer l’impact sanitaire de la pollution de l’air, et les dizaines de milliers de décès prématurés qu’elle provoque chaque année en France et dans le monde, certains font de la résistance.

Ce « déni de la pollution de l’air » se manifeste aussi sous une autre forme, dans certaines études « scientifiques » financées par des constructeurs automobiles. Le New York Times a raconté il y a quelques jours comment une officine crée par Volkswagen avait payé des chercheurs pour faire respirer des vapeurs de diesel à un groupe de singes, dans le but de prouver leur innocuité.

Delhi doctors declare pollution emergency as smog chokes city | World news | The Guardian
Delhi’s air quality is extremely poor for most of the year due to road dust, open fires, vehicle exhaust fumes, industrial emissions and the burning of crop residues in neighbouring states...
As awareness of the problem in Delhi has grown, various methods have been tried to clear the atmosphere including shutting down a local coal-fired power station, traffic rationing and banning firecrackers during Diwali, the annual Hindu festival.

But any lasting solution would need to simultaneously tackle the myriad sources of pollution and involve dozens of state and municipal governments in a country where law enforcement is notoriously patchy.

Though Delhi gets most attention, toxic air afflicts the entire north Indian plain, including parts of Pakistan. A study last year found the holy city of Varanasi had among the worst air in the country.

Motorcycles and emissions: The surprising facts - LA Times
Motorcycles and scooters are, on average, about twice as fuel efficient as cars. Compact and lightweight, their internal-combustion engines do a better job of converting fuel into energy that makes the vehicle move. But extracting more energy from the fuel has a downside. It produces greater amounts of a smog-forming emission called oxides of nitrogen.

Government's Brexit Repeal Bill 'Power Grab' Threatens UK Environment Regulations | DeSmog UK
The reasoning behind this is that currently Britain, as part of the EU, adheres to the Lisbon Treaty which entered into force in 2009 and was signed by all EU member states. The Lisbon Treaty is based on “the precautionary principle and on the principles that preventive action should be taken, that environmental damage should as a priority be rectified at source and that the polluter should pay.” But once Brexit happens, it’s likely that this constraint will no longer apply unless specifically retained by new UK law.

Air pollution - it's about time more noise was made about this | Forum | road.cc
I believe about 90% of air pollution in *London* comes from vehicular sources. It's certainly most of it since the first Clean Air Act (1956 et seq). As for non-smokeless fuel being used in fireplaces and stoves, this is already illegal in pretty much every city, so if it's really becoming a major contributor to air pollution again (link is external), then enforcement (link is external) should be stepped up.

It does tend to piss off the neighbours, and it is rather an easy crime to detect…

There are lots of less polluting choices for room heating; rather fewer for the tremendous energy density embodied in a tank of petrol…

Revealed: every Londoner breathing dangerous levels of toxic air particle | Environment | The Guardian
The scale of London’s air pollution crisis was laid bare on Wednesday, with new figures showing that every person in the capital is breathing air that exceeds global guidelines for one of the most dangerous toxic particles.

The research, based on the latest updated London Atmospheric Emissions Inventory, shows that every area in the capital exceeds World Health Organisation (WHO) limits for a damaging type of particle known as PM2.5.

It also found that 7.9 million Londoners – nearly 95% of the capital’s population – live in areas that exceed the limit by 50% or more. In central London the average annual levels are almost double the WHO limit of 10 µg/m3.

Exploiting crowdsourced geographic information and GIS for assessment of air pollution exposure during active travel
In this study, to explore the potential of crowdsourced geographic information in research of active travel and health, we used Strava Metro data and GIS technologies to assess air pollution exposure in Glasgow, UK. Particularly, we incorporated time of the trip to assess average inhaled dose of pollutant during a single cycling or pedestrian trip. Empirical results demonstrate that Strava Metro data provides an opportunity to an assessment of average air pollution exposure during active travel. Additionally, to demonstrate the potential of Strava Metro data in policy-making, we explored the spatial association of air pollution concentration and active travel.

Brain pollution: Evidence builds that dirty air causes Alzheimer’s, dementia | Science | AAAS
an 11-year epidemiological study to be published next week in Translational Psychiatry, USC researchers will report that living in places with PM2.5 exposures higher than the Environmental Protection Agency’s (EPA’s) standard of 12 µg/m3 nearly doubled dementia risk in older women. If the finding holds up in the general population, air pollution could account for roughly 21% of dementia cases worldwide, says the study’s senior author, epidemiologist Jiu-Chiuan Chen of the Keck School of Medicine at USC.

Deepening the concerns, this month researchers at the University of Toronto in Canada reported in The Lancet that among 6.6 million people in the province of Ontario, those living within 50 meters of a major road—where levels of fine pollutants are often 10 times higher than just 150 meters away—were 12% more likely to develop dementia than people living more than 200 meters away.

Surprisingly, the tiny number of models that did not exceed the standard were mostly Volkswagens, the carmaker whose cheating of diesel emissions tests which emerged last year sparked the scandal. Experts said the new results show that clean diesel cars can be made but that virtually all manufacturers have failed to do so.

Mortality from Diesel Car Pollution in the UK | Energy Matters
On Tuesday 4th April Channel 4 News in the UK carried a report on the impact of pollution from diesel cars upon UK mortality. It was claimed that pollution from diesel cars accounted for 40,000 excess deaths in the UK each year: 29,000 down to particulate matter (PM2.5) and 11,000 down to nitrogen oxides (NOx). The source of the statistics was a report from the Royal College of Physicians called Every breath we take: the lifelong impact of air pollution published in 2016. I decided to delve into the statistics and conclude that PM2.5 pollution from diesel cars may reduce life expectancy by between 2 and 22 days. Fake science and fake news is getting us into deep trouble...
The following story covered air pollution in UK cities, in particular NOx (nitrogen oxides) and soot emissions from the engines of diesel cars, that was reported to be prematurely killing 40,000 UK citizens per year!

Do the Health Benefits of Cycling Outweigh the Risks?
On average, the estimated health benefits of cycling were substantially larger than the risks of cycling relative to car driving. For the society as a whole, this can be even larger because there will be a reduction in air pollution emissions and eventually fewer traffic accidents. Policies stimulating cycling are likely to have net beneficial effects on public health, especially if accompanied by suitable transport planning and safety measures.

A short-term intervention study - Impact of airport closure due to the eruption of Eyjafjallajokull on near-field air quality - Research Portal, King's College, London
We show that the airport closure resulted in an unambiguous effect on NOx and NO2 concentrations close to the airport, even though the ban only lasted six days. Furthermore, we estimate the annual impact airport emissions have on mean concentrations of NOx and NO2 for different years and compare these estimates with a detailed dispersion modelling study and previous work that was based on the analysis of monitoring site data. For the receptor most affected by the flight-ban approximately 200 m south of the airport we estimate the airport contributes about 13.5 mu g m(-3) NOx (approximate to 23% of the total measured NOx concentration), which is similar in magnitude to detailed dispersion modelling estimates of 12.0 mu g m(-3), but approximately twice that of other estimates based on the analysis of ambient measurements. Other measurement sites showed more mixed results due to the prevailing meteorology at the time of the ban, which affected the extent to which these sites were affected by the flight-ban.

Cyclists exposed to five times less air pollution than those in cars | Cycling Today
A collaboration between Kings College London, the Camden Council and the Healthy Air Campaign appears to show that those who travel by car are exposed to pollution levels five times those who cycle, and 3.5 times those who walk.

Air pollution detectors were fitted to one person driving a car, one on a bus, one on foot and one on a bike, all in London.

Someone travelling in their car will be subjected to a greater volume of pollution because exhaust from other vehicles enter the car and isn’t able to disperse. Cyclists, on the other hand, don’t have the fumes trapped in close proximity to them.

Pollution de l'air : quels sont les risques pour la santé ?
Malgré tout, il reste difficile de chiffrer précisément l'impact sanitaire des particules fines en termes de mortalité. Les chiffres de 42 000 morts en France et 386 000 en Europe régulièrement avancés, sont fondés sur une étude de la Commission européenne utilisant des données datant d'une quinzaine d'années.

L'étude la plus à jour est sans doute celle qui est issue du programme européen Aphekom, reprise par l'Institut de veille sanitaire (INVS) en 2012, qui a passé au crible 25 villes de l'Union européenne, dont 9 en France. Les experts ont conclu à des espérances de vie réduites, à 30 ans, de 3,6 à 7,5 mois selon les villes. Au total, 2 900 morts prématurées sont dues chaque année aux particules fines sur ce bassin de 12 millions d'habitants.

Les premiers parce qu'ils ne respectent pas l'obligation qui leur est faite de produire des véhicules dont les émissions sont inférieures aux seuils légaux en conditions réelles d'utilisation ; les seconds du fait de leur incapacité à faire en sorte que leurs constructeurs nationaux respectent la loi.

Pourquoi si peu de réactions face à la pollution de l’air ?
Car, à l’inverse par exemple de l’alcool et du tabac qui sont des risques individualisés dont on peut se protéger sans d’autre coût que le renoncement à leur consommation, la pollution de l’air fait partie de ces risques globaux qu’a produit la modernité. On ne peut lutter contre elle que par un engagement collectif et des choix drastiques qui ont des coûts élevés, car ils impliquent des changements de modes de vie, voire de modèle de société.

L’obstacle ne serait toutefois pas insurmontable si, dans un contexte de doute sur la maîtrise politique de notre destin collectif, les hommes politiques qui se font le mieux entendre, n’étaient pas ceux qui s’emparent des problèmes les plus visibles, en donnent des explications simples et prétendent y apporter des réponses efficaces.

Air Quality Sensor: Series 500 Portable Air Monitor
The Series 500 air quality sensor enables accurate real-time surveying of common outdoor air pollutants, all in an ultra portable handheld monitor. Air quality professionals typically use the Series 500 for short term air quality studies and carrying out checks on pollution “hot spots”. The Series 500 can also be deployed for short term fixed monitoring by adding an optional outdoor enclosure.

Data is stored on board the Series 500 with a maximum 8,188 records available. To download the data a USB cable is supplied for connection to PC. Free PC software provided with the Series 500 takes the data and presents it in a chart or table view. Data can be downloaded and viewed in Excel.

Like all our handheld monitors the Series 500 portable air quality sensor takes advantage of the unique sensor head format. Sensors are housed within an interchangeable cartridge (“head”) that attaches to the monitor base. The head can be removed and replaced in seconds, allowing users to measure as many gases as they wish. Sensor heads feature active fan sampling which ensures a representative sample is taken and therefore increases measurement accuracy.

Other features on the Series 500 include monitor ID and location ID. Monitor ID identifies the monitor uniquely and ensures that all data from it are tied to that monitor. Location ID can be used to tag measurements to a specific location which is helpful when sampling at a number of sites over the course of a day or week.

Non, le pic de pollution n’est pas venu des centrales à charbon allemandes
Le terme PM10 désigne la taille des particules (un diamètre de 10 µm, soit 10 millièmes de millimètre, ou moins). Ces dernières sont considérées comme particulièrement néfastes pour la santé à forte concentration. Or, il existe différents types de particules PM10. Il est donc possible d’avoir des indications sur leur origine en fonction de leur composition.

C’est ce qu’a fait l’institut de mesure de la qualité de l’air pour le pic de pollution de début décembre : « Les centrales thermiques produisent des particules soufrées, explique Karine Léger, porte-parole d’Airparif. Or, il y en avait très peu pendant cet épisode de pollution, seulement des traces. »

A l’inverse, d’autres marqueurs relatifs à d’autres types de pollution ont été observés pendant le pic de pollution. C’est notamment à partir de cette base que les experts ont pu affirmer que la grande majorité de la pollution n’était pas d’origine industrielle (Allemagne comprise), mais issue du trafic routier et du chauffage au bois.

Well, that is broadly the air quality issue – except for the bit about action. Government action to date has concentrated on trying to defend a series of legal challenges by the environmental law group ClientEarth, which is seeking to enforce a clean-up. Why no action? Because the major urban pollution source is motor vehicles, and governments are terrified of motoring lobbies. As we said earlier this year, the motor lobby has far more influence than deprived children living next to major urban roads.

Spare the Air program - Wikipedia
Spare the Air days are declared for days in which levels of ground-level ozone (a constituent of smog) are predicted to exceed the EPA's federal health-based standard of 84 ppb, or an air quality index over 100.[2] On a Spare the Air day, Bay Area residents are asked through radio and television announcements to reduce their driving, refrain from using gas-powered gardening equipment and curb other air polluting activities such as painting and aerosol spray can usage. People especially sensitive to smog are advised to limit their time outdoors.

Spare the Air nights are also issued during the winter when particulate emissions often coming from wood burning and other activities become trapped in stagnant air masses. During winter Spare the Air nights, wood burning is banned and violators may have to attend a class or pay a fine of up to $500. Exceptions are allowed if a household has a power outage. Barbecues are permitted on a Spare the Air Day, but are discouraged to reduce air pollution.[3]

Mais les enjeux des pollutions locales sont …locaux. Et entre un niveau global d’émissions (à l’échelle française par exemple) et des problèmes locaux (pic de pollution quotidien ou hebdomadaire), le lien est loin d’être évident. Ainsi, les émissions globales décroissent mais les concentrations stagnent comme ces suivis annuels d’AirParif le montrent… et l’on ne sait pas grand-chose des expositions réelles des populations (selon les lieux, temps et modes de vie notamment).

Les sources d’émissions sont multiples mais la diésélisation du parc de véhicules et le maintien de chauffage bois, des feux de cheminées dans des foyers ouverts plus précisément, sont responsables de la moitié des émissions. Ensuite, agriculture et industrie complètent le tableau général. Mais à proximité des axes de circulation ou dans certaines vallées, les émissions liées aux trafics routiers ou au chauffage sont bien entendu plus importantes.

Potential pollution exposure reductions from small-distance bicycle lane separations
Three cyclists were equipped with a set of identical instruments and rode continuously along a road, the road׳s sidewalk (7 m away) and an off-road path (19 m away), for a total of 6 h and 45 min, over 5 afternoon sampling runs during fall. Data were analysed in the form of linear mixed-effects models, with cyclist position (distance from edge of nearest traffic lane), wind speed, and temperature, having statistically significant effects on mean exposures (p<0.05). Mean exposure to UFPs and CO were approximately 20–30% (p<0.01) lower at the sidewalk and 40–50% lower at the path, than at the road (p<0.01). These results highlight the potential exposure benefits of segregating cycleways, which helps inform city planning. Separating cycle lanes on key routes could help reduce cyclists׳ cumulative intake of pollutants, especially on heavily-trafficked roads.

Three hundred million of the world’s children live in areas with extreme air pollution, where toxic fumes are more than six times international guidelines, according to new research by Unicef.

The study, using satellite data, is the first to make a global estimate of exposure and indicates that almost 90% of the world’s children - 2 billion - live in places where outdoor air pollution exceeds World Health Organisation (WHO) limits.

Unicef warned the levels of global air pollution contributed to 600,000 child deaths a year – more than are caused by malaria and HIV/Aids combined.

Particulate air pollution and impaired lung function - F1000Research
Air pollution is associated with millions of premature deaths worldwide1, 25% of which are estimated to be respiratory in nature2, and is the world’s largest environmental health risk3. In an attempt to mitigate ambient exposure to air pollution, the Environmental Protection Agency (EPA) currently regulates six criteria air pollutants under the Clean Air Act4. Of the regulated pollutants, particulate matter (PM) has been extensively studied and associated with a myriad of adverse health outcomes, including an adverse impact on lung function in both children and adults5–7. PM is a complex mixture of liquid droplets and extremely small particles composed of organic and inorganic compounds7. PM less than 10 μg in aerodynamic diameter, designated by PM10, can penetrate conducting airways; PM2.5 (PM less than 2.5 μg in aerodynamic diameter) is composed of fine particles and can penetrate into the gas-exchanging regions of the lung6. Sources of ambient PM include construction sites, smokestacks, fires, power plants, and automobiles; the main sources of indoor PM include ambient PM, tobacco smoke, cooking, and heating appliances. PM causes lung inflammation and mucous secretion by acting on airway epithelial cells and alveolar macrophages and may lead to airway remodeling8.
