The FDA has begun reviewing the safety of triclosan, the antibacterial chemical in soaps and toothpaste, and Rep. Edward Markey has called for strict limits. One study showed it can alter hormone regulation, and others suggest exposed bacteria could become resistant to antibiotics.

Where can I learn about the Great Lakes?
A reference page on the Great Lakes: they span more than 750 miles on the Canada-US border and hold about 84 percent of North America's surface fresh water and 21 percent of the world's supply. Farm runoff, city waste, industrial discharges and invasive species threaten them.

America Has Lost More Than Twenty-three Million Acres of Agricultural Land (PR)
American Farmland Trust says the USDA's 2007 National Resources Inventory recorded 4,080,300 acres of working agricultural land converted to development between 2002 and 2007, and 23,163,500 acres since 1982. Prime farmland fell by 13,773,400 acres over the same period.

ARS Strawberries Make Commercial and Home Growing Easy
The ARS strawberry breeding program in Beltsville, Md., the longest continuously running in the country, turns 100. Its releases include Earliglow (1975), sweet and disease resistant, Tribute (1981), which fruits through spring, summer and fall, and Northeaster (1994).

Check out how much you know about healthy home
The EWG Action Fund's room-by-room checklist walks readers through the kitchen, bathroom and laundry, favoring cast iron or stainless over non-stick, glass over plastic containers, filtered tap water over bottled, and fresh or frozen food over BPA-lined cans.

Some basics about pollen allergy
A primer on pollen: counts run highest between 5 and 10 a.m. and on dry, hot, windy days. Fewer than 100 of 50,000 tree species and a small share of North America's 1,200 grasses make allergenic pollen, which brings sneezing, itching eyes and congestion.

Lung function worsens in 9/11 rescuers - study
A New England Journal of Medicine study found lung function still declining years after the World Trade Center attacks. Non-smoking firefighters lost about 25 milliliters of lung volume a year and EMS workers about 40, with 23 percent of each group below normal capacity.

New EMF Dangers - - Type 3 Diabetes and Heart Disease
Mercola presents videos in which Magda Havas reports that some diabetics' blood sugar rose when they exercised on a treadmill but fell when they walked outdoors, and that radiation from a cordless DECT phone interfered with the heart at levels well below federal guidelines.

Brain Drain? PBDEs Alter Development of Human Brain Cells
Schreiber and colleagues exposed fetal human neural progenitor cells to the flame retardants BDE-47 and BDE-99. At non-cytotoxic concentrations the compounds left proliferation alone but reduced cell migration and altered differentiation, apparently by disrupting thyroid hormone signaling.

Mystery in a Bottle: Will the EPA Require Public Disclosure of Inert Pesticide Ingredients?
Up to 99% of a pesticide product's ingredients have legally stayed hidden as trade secrets, but the EPA is weighing what it calls a sea change toward full disclosure. State lawyers and poison control staff say the secrecy delays treatment; an industry group wants the situation left largely as it is.
Environment
How Airplane Cabin Air Can Get You Sick
Cabin air is drawn in through the aircraft engine, so engine oil mist can seep in when there is a leak. Dr. Mercola writes that crew and passengers have reported headaches, dizziness and tremors afterward, and names the engine oil additive tricresyl phosphate as a neurotoxin.

Chemical exposure before mid-30s triples breast cancer risk
Comparing 556 Montreal women with breast cancer to 613 controls, researchers found that workplace exposure to certain chemicals before age 36 carried particularly high risk: acrylic fibres were linked to a sevenfold risk and nylon fibres to roughly double.

New Law May Slow Cell Phone Cancer Epidemic
A Maine bill, HP 1207/LD 1706, would make the state the first to require labels warning that cell phones can cause brain cancer, especially in children. One supporter compares waiting to the delay over smoking; the wireless industry calls the bill grandstanding.

Ground Water Awareness Week
A CDC piece for National Ground Water Awareness Week, March 7-13, 2010, urging well owners to test their water yearly and inspect well caps. Ground water supplies 30 percent of available US freshwater and feeds both community systems and private wells.
Environment
How Grass-Fed Cows Could Save the Planet
Rotating cattle across pasture spurs regrowth and works manure into the soil, and healthy soil keeps carbon underground. Grass-fed cattle emit more methane than feedlot cattle, the piece says, but their net emissions are lower. Currently 99 percent of US beef cattle finish on feedlots.

Even Drugs Thrown in the Trash Can End Up in Your Drinking Water
Maine's environmental agency found tiny amounts of discarded pharmaceuticals in water at three state landfills, suggesting drugs thrown into household trash, the federal government's recommended disposal route, still reach water supplies.

No Fluoridated Water for Infants (PR)
The California Dental Association advises against routinely mixing infant formula with fluoridated water, saying it may raise a child's chance of enamel fluorosis. NYSCOF notes similar cautions from the National Research Council and the ADA date back to 2006.

This Silent Killer Now Verified in Non-Smoker's Lung Cancer
Radon, a radioactive gas released as uranium breaks down in rock, soil and water, ranks as the second leading cause of lung cancer in the US and the first among non-smokers, with an estimated 15,000 to 22,000 deaths a year. Mercola urges readers to find out how much they are exposed to.
