Wind, water, and waves erode billions of tons of soil from the earth's surface. As a result, many rivers are plagued with excessive amounts of suspended sediment. According to the U.S. Environmental Protection Agency, such eroded sediment is the largest nonpoint source pollution in the environment.

Environmental Radiation Monitoring Gets Close Look In Morocco

Modern nuclear techniques are giving the world's scientists and regulators better tools to fight pollution and other environmental threats – even those that may be lurking naturally at the beach or near your backyard. Many of the world's top "radioecologists" are in Morocco this week to assess a dynamic picture.

Pollution From Livestock Farming Affects Infant Health

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.

"Chemical Equator" Found to Divide the World

Iria — Tue, 23 Sep 2008 15:15:46 -0500

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.

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.

Lake sediments help scientists trace 7,000 years of mining, metal use in China

harminka — Mon, 16 Jun 2008 08:37:03 -0500

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.

Road pollution blamed for higher allergy risk in kids

harminka — Fri, 13 Jun 2008 12:56:27 -0500

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.

Next-generation explosives, more power and safety without pollution

harminka — Mon, 26 May 2008 08:36:07 -0500

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.

Atmosphere threatened by pollutants entering ocean

harminka — Fri, 16 May 2008 06:51:32 -0500

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.
