When cold air traps pollutants over Johannesburg on winter afternoons, a brown haze can form, with particulate matter levels that exceed South Africa's ambient air quality standards. (1) In mid-June [...]

Low-income communities of color are inequitably burdened with pollution and its related health effects. (1) Environmental health researchers sometimes conduct community-based participatory research projects in which residents help design research [...]

Smoke from burning landscapes--including wildfires, prescribed burns, and agricultural clearing--can raise concentrations of fine particulate matter ([PM.sub.2.5]) and other harmful air pollutants in areas hundreds or even thousands of miles [...]

Climate change presents a significant and growing threat to human health, with diverse impacts projected for different regions. (1) Investigators now report that Pacific island countries including Fiji, Tonga, and [...]

Studies of several different oil spill disasters have shown that the people affected by these disasters can suffer adverse mental health and behavioral effects. (1,2) But does the psychological impact [...]

Worldwide, the preponderance and severity of wildfires is increasing due to a number of factors, among them changes in temperature and precipitation patterns consistent with climate change. (1,2) Aside from [...]

Researchers have previously reported associations between exposure to air pollution during pregnancy and decreased birth weights. (1,2) However, in any given location there is usually very little variation in air [...]

Numerous studies have examined exposures to indoor combustion products such as secondhand smoke and emissions from burning of solid fuels. However, only a few have examined incense burning as a [...]

An error has been noted in the article 'New Blood: The Promise of Environmental Health Citizen Science Projects.' The caption for the image of the Gardenroots instruction manual incorrectly states [...]

Monica Ramirez-Andreotta sat on a folding chair holding a notebook and pen in the Humboldt Elementary School gym. It was August 2008, and Leah Butler, a project manager with the [...]

The article highlights the recarbonizing of earth soils which are estimated to have lost billions of metric tons of carbon to the atmosphere when agriculture started. Recarbonizing global soil pool methods include cover cropping, no-till farming and enriching soil with biochar, a charcoal used as a soil amendment, which are noted to help in increasing the carbon levels.

The article discusses adverse health effects and public health impact related to wildfire smoke inhalation, focusing on a study by Colleen E. Reid and colleagues which linked wildfire smoke with increased mortality rates and multiple respiratory conditions, such as asthma and chronic obstructive pulmonary disease, through the review of several epidemiological studies. Topics include the tendency for the studies to have many natural biases and lack of consistent evidence for specific causes of mortality.

An article on the benefits of walking and walkable neighborhoods for hypertension patients is introduced.

The article discusses a study by lead author Zorana Jovanovic Andersen and colleagues on the effects of exposure to air pollution while exercising. The study suggests that long-term exposure to air pollution while exercising did not reduce or outweigh the beneficial health effects of physical activity on mortality rate and heart and lung health.

The article discusses the relationship between incense use for religious and ritual purposes and cardiovascular diseases. The Singapore Chinese Health Study found that long-term incense users had a 12 percent increased risk of cardiovascular mortality, as compared too non-users. Previous studies have shown that volatile organic compounds and particulate matter in incense emissions are similar to those found in cigarette smoke.

The article presents research on breast cancer and study on chemicals, biomarkers and environmental assessment tool that contribute to breast cancer risk. It mentions of a study led by author Ruthann Rudel and colleagues on 102 chemicals linked with mammary tumors in rodent and 91 of 102 chemicals were evidence of carcinogenicity in humans. It informs that epidemiologist Dora Il'yasova reflects on the difficulty while performing biomarker-based exposure assessments.
