Evidence is Growing That Contaminants Play a Role in Diabetes

Eat right and exercise, conventional wisdom has it, if you want to avoid joining the diabetes epidemic. But a new study adds some muscle to a growing body of research suggesting those steps, although beneficial, might not be enough for people exposed to chemicals in the environment. The scientists linked diabetes and people's body burdens of DDE, a chemical produced as the body breaks down the pesticide DDT, banned in the United States more than 35 years ago.

Air Pollution Linked to Diminishing IQ of Children

A new study published in the August 2009 edition of Pediatrics shows a possible disturbing correlation between increased urban air pollution and decreased IQ points in children. The study sites polycyclic aromatic hydrocarbons (PAHs), or "chemicals released into the air from the burning of coal, diesel, oil, and gas, or other organic substances such as tobacco" as the major perpetrators of inner- city air pollution, with a particular focus on motor vehicle use.

Fertilizer’s Contamination Legacy
July 19, 2009 07:21 AM - , Organic Consumers Association

Perchlorate-contaminated groundwater could be a widespread legacy of the U.S.'s agricultural past, according to researchers who have pioneered perchlorate forensics. The researchers, led by John Karl Bhlke of the U.S. Geological Survey, used isotopes and other geochemical tracers to identify perchlorate sources. The impact of the historic use of Chilean nitrate fertilizer from the Atacama Desert, which contains naturally occurring perchlorate, is emerging from studies such as one published recently in ES&T.

Mystery of Los Angeles Methane Emissions Probed
July 19, 2009 07:09 AM - New Scientist

The Los Angeles metropolitan area belches far more methane into its air than scientists had previously realized. If other megacities are equally profligate, urban methane emissions may represent a surprisingly important source of this potent greenhouse gas. Atmospheric researchers have long had good estimates of global methane emissions, but less is known about exactly where these emissions come from, particularly in urban areas.

Are Aluminum Bottles Greener than Glass?
July 18, 2009 11:33 AM - , Triple Pundit

Aluminum as a substitute for glass bottles has been inching its way into the consumer experience in the last few years, most notably in the US in the form of beer bottles from Anheuser-Busch and Iron City Beer, a popular regional brand founded in Pittsburgh. Coca-cola has also announced plans to roll out aluminum bottles in this country, though only in limited venues.

The Food and Drug Administration believes antibiotics should be used on livestock only to cure or prevent disease and not to promote growth, a common use, said a high-ranking FDA official on Monday. Principal deputy FDA commissioner Joshua Sharfstein said restrictions on livestock use would reduce the opportunity for bacteria to develop resistance to drugs used by
