Air Pollution Linked to Infant Deaths | Global Health | JAMA | JAMA Network
Poor air quality is responsible for 1 in 5 infant deaths in sub-Saharan Africa, according to a study published in Nature.

To quantify the effect of breathable air pollutants on premature deaths among infants in Africa, the investigators examined recent satellite-based estimates of air pollutant particles (ambient respirable particulate matter with an aerodynamic diameter less than 2.5 μm [PM2.5]). They combined the air quality data with results from 65 household surveys across 30 sub-Saharan African countries on the timing and location of almost 1 million infant births—and any subsequent deaths in the first year of life—between 2001 and 2015. They then matched the location and timing of each birth to satellite-based estimates of PM2.5 exposure from 9 months before birth to 12 months after.

The investigators found a strong linear association of infant mortality with increases in PM2.5 exposure. Specifically, with every 10 μg per cubic meter increase in the concentration of breathable particulate matter in the first 12 months of life, there was about a 9% increase in infant mortality. This association was consistent over the study’s 15 years and was independent of household wealth.

Concentrations of PM2.5 higher than minimum exposure levels were responsible for 22% of infant deaths in 30 countries and led to 449 000 additional infant deaths in 2015. This estimate is more than 3 times higher than earlier data, suggesting poor air quality is an even bigger problem than previously appreciated.

Association Between Fine Particulate Matter and Diabetes Prevalence in the U.S.
OBJECTIVE Recent studies have drawn attention to the adverse effects of ambient air pollutants such as particulate matter 2.5 (PM2.5) on human health. We evaluated the association between PM2.5 exposure and diabetes prevalence in the U.S. and explored factors that may influence this relationship.

RESEARCH DESIGN AND METHODS The relationship between PM2.5 levels and diagnosed diabetes prevalence in the U.S. was assessed by multivariate regression models at the county level using data obtained from both the Centers for Disease Control and Prevention (CDC) and U.S. Environmental Protection Agency (EPA) for years 2004 and 2005. Covariates including obesity rates, population density, ethnicity, income, education, and health insurance were collected from the U.S. Census Bureau and the CDC.

RESULTS Diabetes prevalence increases with increasing PM2.5 concentrations, with a 1% increase in diabetes prevalence seen with a 10 μg/m3 increase in PM2.5 exposure (2004: β = 0.77 [95% CI 0.39–1.25], P < 0.001; 2005: β = 0.81 [0.48–1.07], P < 0.001). This finding was confirmed for each study year in both univariate and multivariate models. The relationship remained consistent and significant when different estimates of PM2.5 exposure were used. Even for counties within guidelines for EPA PM2.5 exposure limits, those with the highest exposure showed a >20% increase in diabetes prevalence compared with that for those with the lowest levels of PM2.5, an association that persisted after controlling for diabetes risk factors.

CONCLUSIONS Our results suggest PM2.5 may contribute to increased diabetes prevalence in the adult U.S. population. These findings add to the growing evidence that air pollution is a risk factor for diabetes.

Airplanes emissions kill around 8,000 people per annum
Aviation emissions contribute to this health problem, according to a new study that suggests that airplanes flying at a cruise altitude of around 35,000 feet emit pollutants that contribute to about 8,000 deaths per year globally.

People Near Freeways Are Exposed To 30 Times The Concentration Of Dangerous Particles
Bottom line: live at least 300m from freeways.

"After about 300 meters (~990 feet) the concentration of particulate matter reaches the “ambient” level – the normal level in the air without the influence of any nearby sources. " --

Each Ton of CO2 Worth $40 in Health Costs : CleanTechnica
Using coal for electricity produces CO2, and climate policy aims to prevent greenhouse gases from hurting our habitat. But it also produces SOx and NOx and particulate matter that have immediate health dangers.

A University of Wisconsin study was able to put an economic value on just the immediate health benefits of enacting climate policy. Implications of incorporating air-quality co-benefits into climate change policymaking found coal is really costing us about $40 per each ton of CO2.
