A new study in the American Journal of Agricultural Economics explores the effects of pollution from livestock facilities on infant health and finds that production is associated with an increase in infant mortality.

The world is divided, but not by political views or a line on a map. No, the world is divided by what scientists have dubbed a "chemical equator" that "separates" polluted air from Southeast Asia from the largely uncontaminated atmosphere of the Southern Ocean that surrounds Antarctica. But this is the second such equator scientists have found.

Everyday exposure to environmental tobacco smoke, allergens, and air pollution may be the root of chronic cases of laryngitis, says new research presented at the 2008 American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL.

Selenium has been referred to as an “essential toxin” due to the fact that it shows only a marginal line between the nutritious requirement and toxic effects upon exposure.

The emergence of electric lighting at night nearly a century ago has positively affected countless aspects of human life, ranging from improved safety and security to stronger economic development.

A new geochemical study illuminates 7,000 years of mining and metal use in central China and links these trends to fluctuations in airborne pollution during the Bronze Age and other military and industrial periods in Chinese history. The study, which could help scientists better assess the accumulative environmental effects of human activity in the region since prehistory times, is scheduled for the July 1 issue of the ACS' Environmental Science & Technology, a semi-monthly journal.

New evidence blames traffic-related pollution for increasing the risk of allergy and atopic diseases among children by more than fifty percent. What's more, the closer children live to roads, the higher their risk.

Scientists in Germany are reporting development of a new generation of explosives that is more powerful than TNT and other existing explosives, less apt to detonate accidentally, and produce fewer toxic byproducts. Their study of these more environmentally friendly explosives is scheduled for the June 24 issue of ACS’ Chemistry of Materials, a bi-weekly journal.

A large quantity of nitrogen compounds emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere, concluded a team of international scientists led by Texas A&M University Distinguished Professor of Oceanography and Atmospheric Sciences Robert Duce.

Researchers at the Johns Hopkins Bloomberg School of Public Health have conducted the largest nationwide study on the acute health effects of coarse particle pollution. Coarse particles are airborne pollutants that fall between 2.5 and 10 microns in diameter.

Montana State University research about pollution in the Ganges River has reached the Supreme Court of India, producing some optimism among MSU scientists who study the 1,500-mile river.

NOAA scientists are now flying through springtime Arctic pollution to find out why the region is warming — and summertime sea ice is melting — faster than predicted. Some 35 NOAA researchers are gathering with government and university colleagues in Fairbanks, Alaska, to conduct the study through April 23.
