Risks from Lawn-Care Pesticides
Dogs absorb chemicals from pesticide-treated lawns Dogs are being exposed to garden and lawn chemicals associated with bladder cancer, according to a new study led by Deborah Knapp of Purdue University's Department of Veterinary Clinical Sciences. Researchers suggest that owners who use herbicides should allow lawns to dry before allowing pets to walk on the grass. Wash the dog's feet every time it comes inside. Alternate weekly treatments to front and back yards to reduce exposures.
Connecticut Pesticide Notification Registry The pesticide pre-notification registry allows Connecticut residents to be notified when their abutting neighbors have their property commercially treated with pesticides.

Atrazine found in lakes far from farm sources
The herbicide, apparently carried by wind and rain, is turning up far from farm country, in pristine lakes in northern Minnesota. One of the most widely applied herbicides in North America, atrazine is used mainly to control weeds in cornfields. Click here for full story.
Canadian province bans weed and feed lawn products
Alberta announced a ban on herbicide-fertilizer combination products. Known most commonly as weed and feed, the products contain a chemical called 2,4-D (2,4-dichlorophenoxyacetic acid) that is "highly mobile" when it runs off lawns into storm drainage systems and subsequently drains into creeks and rivers.

Rats are fat after long-term exposure to lower levels of atrazine
Much of the water in the Midwest is contaminated with the agricultural pesticide atrazine. A new study in Environmental Health News suggests a mechanism to explain prior studies that found high prevalence of obesity in areas of the United States with heavy atrazine use. This study also shows that high-dose experiments do not predict low-dose results, which calls into question many federal safety standards presumed to protect human health. Click here for news story.
EPA announces plan to require disclosure of secret pesticide ingredients
Reversing its policy of the last decade, the U.S. Environmental Protection Agency will now require pesticide manufacturers to publicly disclose inert ingredients in pesticide products. Nearly 4,000 inerts—including several hundred that are considered hazardous under other federal rulea—are used in agricultural and residential pesticides. Although some secret ingredients are toxic, manufacturers have not been required to identify them on pesticide labels. Click here for news stry.
