   Its great to see the health problems from air pollution being recognised, but why mention power stations but not domestic wood stoves?
   
   Residential wood burning contributes more fine particle (PM2.5) pollution to Southern California's air than all the power plants in Los Angeles, Orange, San Bernardino and Riverside counties combined: http://www.aqmd.gov/healthyhearths/index.htm
   
   The Lung Association of Quebec reports that wood heating is responsible for 61% of Quebec's fine particle emissions: http://www.pq.lung.ca/environment-environnement/wood_smoke-fumee_bois/enjeu-montreal/
   
   In Sydney, Australia, wood heating, used by less than 8% of households, is the largest single source of PM2.5 pollution  4,503 tonnes per year, compared to 840 tonnes from light duty diesels, 797 tonnes from petrol cars and 681 tonnes from heavy duty diesels: http://www.3sc.net/airqual/NSW07_emss_invent.html
   
   Virtually all Sydneys electricity comes from coal-fired power stations, but filters and tall chimneys ensure it doesnt affect the health of the population, unlike woodsmoke and diesel emissions. Using woodstoves often creates a dangerous build-up of fine particle pollution in areas where families live. In Christchurch, NZ, estimated health costs exceed $2,700 dollars per woodstove per year: http://www.3sc.net/airqual/mapping.html
   
   There is no safe level of PM2.5 pollution, below which no adverse health effects are observed. The requirement to meet air quality standards forced Montreal to ban the installation of new woodstoves in April 2009, their health costs being many times greater than any possible benefits.
   
   Southern California, too, prohibits woodstoves in new homes, subsidises the removal of existing stoves and even bans their use on days when a build-up of woodsmoke is forecast.
   
   The first step in any program to clean the air should be to restrict or ban devices (e.g. diesel engines with no pollution control equipment and woodstoves  even new one have average more PM2.5 pollution per year than 100 to 200 passenger cars) that create health costs far greater than any possible benefits of using them.

   So (due to air pollution), "grave health effects—including death—are all too common". That's odd. I don't recall ever hearing of any particular person dying from air pollution. I'll have to read the obituaries a little more closely.

   Soccerdad : Have you ever wondered why smoking was virtually banned? And just look at the statistics on Asthma in polluted areas. People may not die often of asthma, but it is a very incommoding problem to the millions of sufferers, often pre-adolescents. But lung cancer does kill, and it kills more and more non-smokers, especially in China.

   eco-steve,
   
   What does smoking have to do with air pollution as referenced in the ariticle? The implication is that this is caused by industry and ships - not cigarette smoke. It's always more dramatic to blame industry as the bad guys when most deaths are self inflicted due to life style or other natural causes unrelated to the environment.
   
   And, because of references to the Clean Air Act, it is clear that the article is focused on the U.S., perhaps including other modern Western countries. China is a whole different discussion with regard to air pollution due to all the coal burned without any scrubbing.
   
   So, my point is undiminished. If deaths from air pollution are "all too common", you would think the average person would know of at least one person that they knew who is suspected of having died from air pollution. I would venture that this is not the case, and therefore the statement is assuming facts not in evidence.

   Just a reminder: these efforts will cost serious money.
   
   For those who are old enough to remember when dirty diesel cost less than gasoline; now that it has been cleaned up, diesel costs more than gasoline.

   My eldest son has asthma which is triggered by wood smoke burned outdoors recreationally by several of my neighbors in Livonia, MI. We moved here from Troy, MI where fire pits were not a problem. Unfortunately the local fire and police department will not direct my neighbors to put out their fires since there is no law against it even if it threatens the health of my son (and also my next door neighbor who has asthma). I checked with several other cities in the area and I was told that open burning is legal and popular and that perhaps we should live elsewhere", by some individuals due to our health need. I find it shocking and very disappointing that these cities refuse to protect people with asthma who especially need clean air to breathe. We cannot even open our windows in order to reduce the levels of normal indoor pollutants on many days due to the terrible acrid smell of wood smoke outdoors. The cities who responded negative are: Plymouth, Canton, Farmington Hills, and Livonia.
   
   The only city I interviewed that responded favorably to my concern was the city of West Bloomfield since I received a positive response from the City Clerk, Ms. Catherine Shaughnessy. West Bloomfield offers protection for my son! Therefore, perhaps we will need to move to this outstanding city with cleaner air. I commend West Bloomfield for their intelligent, caring, and progressive stance supporting clean air for our environment!

   We live in a society where people have been trained to expect simple answers to complex problems. Conventional wisdom holds that if one cannot prove causation then we can dismiss the concern. This could not be further from the truth. The real truth is that we live in an environment that is full of environmental (such as pollution) stressors. At some point these stressors can trigger disease. But no 2 individuals experience the same collective set of environmental stressors and no 2 physiologies are going to respond in the same way to those stressors. That is why we have to resort to looking for correlations to look for tipping points.
   
   When we observe more deaths due to lung ailments than is normal for a given population and the air pollution levels are known to be significantly higher than the norm, we start to make inferences that air pollution is likely to be the primary culprit. But don't expect to read a specific obituary that claims death due to air pollution any time soon. If you want that kind of unfounded assertion, try the FOX channel.

   If you are living in rural areas where public transportations are not available it can be understandable. However, people from big cities where public transportations, such as subway or buses, are accessible should use them as many as they can instead of driving their own vehicles all the time. Back in South Korea, People are not allowed to drive their vehicles once a week depending on the last number of people’s license plates. For example, if your last number on license plate ends up with 0 or 1 you should leave your car at your house and use public transportations. Governments should come up with ideas like this in order to reduce the air pollution levels.
