Three new studies show fine particles linked to health risks 8 December 2011 Three new studies released today by the California Air Resources Board reveal that exposure to airborne fine-particulate matter significantly elevates the risk for premature deaths from heart disease in older adults and elevates incidence of strokes among post-menopausal women.
The coal seam gas rush November 2011 The ABC's data journalism project has pulled together information from dozens of sources to provide an insight into the promise and the dangers inherent in the coal seam gas rush.
Lung cancer in women on rise, while male rates decline 4 November 2011 The first comprehensive summary of national statistics on lung cancer in Australia was released yesterday by the Australian Institute of Health and Welfare and Cancer Australia. The report revealed that the rate of new lung cancer diagnoses rose by 72 per cent for women but fell by 32 per cent for men between 1982 and 2007. Smoking is the leading case of lung cancer in Australia, but about 10 per cent of men and 30-35 per cent of women who get lung cancer are non-smokers.
Air pollution tied to lung cancer in non-smokers 28 October 2011 People who have never smoked, but who live in areas with higher air pollution levels, are roughly 20 percent more likely to die from lung cancer than people who live with cleaner air, researchers conclude in a new study. "Lung cancer in 'never smokers' is an important cancer. It's the sixth leading cause of cancer in United States," said Michelle Turner, the lead author of the study. Although the study team didn't prove that the pollution caused the cancer cases "there's lots of evidence that exposure to fine particles increases cardiopulmonary mortality". Fine particles in air pollution can injure the lungs through inflammation and damage to DNA.
A particulate threat to diabetics 26 October 2011 In a new study of people with diabetes, blood pressure rose in rough lockstep with short-term increases in soot and other microscopic air pollutant particles. Such transient increases in blood pressure can place the health of the heart, arteries, brain and kidneys at risk, particularly in people with chronic disease. The new data confirm that short-term inhalation of fine airborne particulates at ambient levels — and perhaps traffic-related soot in particular — "have small but potentially clinically meaningful effects."
Fed up with pollution from idling cars - take a lesson from Salt Lake City 25 October 2011 Motorists who leave their vehicles idling for more than two minutes in Utah's capital city run the risk of being fined. "The focus is education." "The goal", city leaders said, "is to improve air quality in the Salt Lake Valley, where more than 50 percent of air pollution comes from vehicle exhaust."

Call for air quality monitoring 18 October 2011 Gunnedah Shire Council calls for air quality monitoring across the Gunnedah Basin It's anticipated there will be some 750 direct and indirect jobs created by the Aston Resources' Maules Creek Coal Project in North West NSW. There is no doubt there will be many economic benefits from the new mines in the region. However there are environmental impacts as well, and not necessarily one we can see. (Audio)
Heating and Air Pollution 18 October 2011 The effects of wood burning are still quite large both in developed and developing countries. In developing countries it is more of an indoor air quality issue, as wood is used for both cooking and heating, and the carbon monoxide, particulate matter, and polycyclic aromatic hydrocarbons. In developed countries, where cleaner fuels and better combustion technologies are available, it is more of an outdoor air quality issue. Despite efforts in cleaning up industry, cars, trucks, buses, very few "romantic" users of wood burning are causing huge effects on air quality across many cities.
Two New Reasons to Worry about Air Pollution: Obesity and Diabetes 10 October 2011 New studies have found a rather convincing correlation between the presence of small particulate matter (PM2.5, the fine particles blown into the air by road traffic, coal-fired power plants, industrial manufacturing, and residential wood fuel combustion) and both obesity and diabetes.
Air pollution from traffic impairs brain 9 October 2011 Air pollution in cities and beside roads can impair the way the brain functions, two new studies have revealed. Scientists have found living in areas with high levels of traffic pollution can reduce people's performance in cognitive tests.

Asbestos warning 5 October 2011 Hundreds of unsuspecting ACT businesses could contain the same sort of deadly ''fluffy'' asbestos removed from Canberra homes because the buildings were ''outside the scope'' of a $100million clean-up funded by the Federal Government in the late 1980s, an expert says. Related news: 'Commonwealth should help pay for asbestos clean-up.'
New study shows how trees can clean the air of particulate pollution 5 October 2011 New research by scientists at the University of Southampton has shown how London’s trees can improve air quality by filtering out pollution particulates, which are damaging to human health. A paper published this month in the journal ‘Landscape and Urban Planning’ indicates that the urban trees of the Greater London Authority (GLA) area remove somewhere between 850 and 2000 tonnes of particulate pollution (PM10) from the air every year.
Results out in Kwinana Children’s Health Respiratory Study 20 September 2011 Study leader Dr Peter Franklin said that overall the respiratory health of Kwinana children is about the same as that of children in other areas of Perth. However, the study found children who lived in Kwinana before the age of three were more likely to have wheezed at least once in their life compared to children who had moved to Kwinana after the age of three – 42.1 per cent versus 26.4 per cent respectively.

1661 Air Pollution Essay Republished 6 Sep 2011 Environmental Protection UK has re-published 'Fumifugium': John Evelyn's 1661 essay on air pollution in London. Evelyn was a 17th century writer, gardener and diarist. In Fumifugium he wrote to King Charles II aiming to document the impacts of air pollution on both health and the environment, and also put forward some solutions to the problem of coal smoke. Unfortunately Charles II did little to implement Evelyn's thinking and it wasn't until the 1950s that the UK introduced effective smoke control laws.
The air you breathe can harm your health 5 September 2011 Air pollution has been recognised as a major contributor to ill health for centuries. While some of the acute effects of smogs, wood and coal burning have been obvious even prior to modern medicine, it is only recently we have started to realise the far greater and more insidious consequences of chronic exposure. There is strong evidence for a causal relationship between air pollutants and respiratory conditions such as COPD, asthma and lung cancer, and cardiovascular diseases, acute myocardial infarctions (AMI) and arrhythmias. This is occurring even with exposure to low concentrations well below current guideline levels.
Woodsmoke likely contribution to poor air quality in Muswellbrook 5 September 2011

Smoke from wood fireplaces, stoves raises new health concerns 14 March 2011
Recent research raises new concerns over the toxic substances borne aloft in wood smoke. Scientists say the tiny airborne specks of pollution carry carcinogenic chemicals deep into lungs and trigger DNA damage and gene changes comparable to the hazards of cigarette smoke and car exhaust.
US EPA drafts new standards for residential wood heaters 1 March 2011
Nationally in the US, residential wood combustion accounts for 13% of PM2.5 pollution, 44 percent of total stationary and mobile polycyclic organic matter (POM) emissions and 62 percent of the 7-polycyclic aromatic hydrocarbons (PAH), which are probable human carcinogens and are of great concern to EPA. The draft standard proposes tightening the emission limit from 7.5 g/hr to 4.5 g/hr for non-catalytic wood heaters. The US EPA has proposed to publish Residential Wood Heater New Source Performance Standards in June 2011 for public comment and may publish the final rule in July 2012. Workshop Presentation (pdf)
Air pollutants from fireplaces and wood-burning stoves raise health concerns 5 February 2011
With millions of people warding off winter's chill with blazing fireplaces and wood-burning stoves, scientists are raising red flags about the potential health effects of the smoke released from burning wood. Their study, published in the American Chemical Society's (ACS') journal, Chemical Research in Toxicology, found that the invisible particles inhaled into the lungs from wood smoke may have several adverse health effects.
The scientists analyzed and compared particulate matter in air from the center of a village in Denmark where most residents used wood stoves to a neighboring rural area with few wood stoves, as well as to pure WSPM collected from a wood stove. Airborne particles in the village and pure WSPM tended to be of the most potentially hazardous size — small enough to be inhaled into the deepest parts of the lungs. WSPM contained higher levels of polycyclic aromatic hydrocarbons (PAHs), which include "probable" human carcinogens. When tested on cultures of human cells, WSPM also caused more damage to the genetic material, DNA; more inflammation; and had greater activity in turning on genes in ways linked to disease.
Acrolein and Neural Disorders 1 February 2011
The causes of neurologic disorders are poorly understood, but one of the emerging suspected culprits is the substance acrolein, which tends to be significantly elevated in the brains or spinal cords of people who have Alzheimer disease, Parkinson disease, amyotrophic lateral sclerosis ), and other neurologic disorders. This new study adds multiple sclerosis (MS) to the list of disorders potentially affected by this substance. Acrolein occurs in combustion by-products such as vehicle exhaust, industrial emissions, oil- and coal-fired power plant emissions, cooking fumes, and the smoke from burning cigarettes and wood.

The Love Affair With the Fireplace Cools 19 January 2011
Hard as it may be to believe, the fireplace — long considered a trophy, particularly in a city like New York — is acquiring a social stigma. Among those who aspire to be environmentally responsible, it is joining the ranks of bottled water and big houses. “In the city, it doesn’t make sense to burn fires, because it’s inefficient and it’s polluting.”
Wood smoke contains some of the same particulates as cigarette smoke, said Dr. Norman H. Edelman, the chief medical officer for the American Lung Association, as well as known carcinogens like aldehydes; it has also been linked to respiratory problems in young children.
Smoking damages the body 'in minutes rather than years' 17 January 2011
