After a decade of deliberations and review of more than 1,700 new studies, the U.S. Environmental Protection Agency (EPA) announced the new primary standard for ground-level ozone in March 2008. The new standard, 75 ppb, is being assailed from all sides

In 2005, months of unprecedented higher-than-normal water temperatures started a cascade of bleaching, disease, and death among corals in the Eastern Caribbean. Such events are increasing in frequency around the world and threaten these fragile ecosystems, which shelter a wealth of biodiversity and provide sources of food and pharmaceuticals. Researchers must determine how rising temperatures produce coral bleaching, the pathogens that cause disease in corals, and the environmental factors that foster disease outbreaks.

Biomass fuel is the primary source of domestic fuel in much of rural China. Previous studies have not characterized particle exposure through time

Biomarkers of systemic inflammation have been associated with risk of cardiovascular morbidity and mortality. The researchers aimed to clarify associations of particulate matter (PM) air pollution with systemic inflammation using models based on size-fractionated PM mass and markers of primary and secondary aerosols.

The capability of benzophenone-3 (BP-3) to absorb and dissipate ultraviolet radiation
facilitates its use as a sunscreen agent. BP-3 has other uses in many consumer products (e.g., as fragrance and flavor enhancer, photoinitiator, ultraviolet curing agent, polymerization inhibitor). The researchers wanted to assess exposure to BP-3 in a representative sample of the U.S. general population ? 6 years of age.

Airborne nanoparticles from vehicle emissions have been associated with adverse

In this study the researchers assessed the association of short-term air pollutant exposure with inflammatory markers and lung function.

This study aimed to investigate the relationship between outdoor ambient air PM2.5 zinc levels and urgent health care utilization for children living in an urban area.

The authors to examine the relationship between environmental cadmium exposure and dental caries in children 6

In this retrospective cohort study the authors examined whether PCE (Prenatal Exposure to Tetrachloroethylene) contamination of public drinking-water supplies in Massachusetts influenced the birth weight and gestational duration of children whose mothers were exposed before the child's delivery.
