What do we know about the health effects of the chemicals we routinely use to keep our lawns and homes pest free? Not as much as we should, considering that these pest control products are used widely by millions of Americans. Recent figures set the amount of pesticides being used on our lawns alone at about 70 million pounds per year! And most of that use is purely for aesthetic purposes.

Rachel Carson, biologist and author of "Silent Spring," who so eloquently warned us of the dangers of pesticides, is regarded as a national hero and credited with the birth of the environmental movement. We have named government buildings and wildlife sanctuaries after her, but we have forgotten her message.

As pesticide products were being developed, scientists warned of the inherent dangers of their widespread use. Recent scientific studies have demonstrated that the chemicals that make up pesticide products persist longer, travel farther and do more damage to humans, wildlife and the environment than anyone predicted. Pesticides used on our lawns wind up on our patio furniture, on our children's toys, in our birdbaths and pools and in our drinking water supply. Further, if you don't remove your shoes at the door, lawn care pesticides can be tracked indoors where they remain for long periods of time. Pesticides used to control indoor pests have an even more direct impact your home environment.

The US Environmental Protection Agency has stated that no pesticide is safe, even when used as directed, and many of the pesticides used on residential lawns are considered probable or possible carcinogens. The health effects of combinations of these chemicals (or their synergistic effects) are of great concern to researchers who have demonstrated that when certain pesticides are combined, their toxicity can increase by as much as 1,000 times. With almost 900 active pesticide ingredients registered for use, testing for these synergistic effects is virtually impossible. (Note: In addition to lawn and home pest controls, many common products are registered "pesticides" - these include household disinfectants, lice shampoos, bug repellents and some deodorizers.)

The "inert" ingredients in pesticides are chemicals that make the product more potent or easier to use (e.g., solvents, surfactants, carriers, synergists, etc.). Pesticide manufacturers claim that these ingredients are trade secrets and should not be disclosed. Inerts are neither chemically, biologically or toxicologically inert, and indeed, some are more toxic than the active ingredients listed.

It also appears that children are disproportionately exposed and affected by pesticides. A National Cancer Institute study found that children were up to six times more likely to get childhood leukemia when pesticides were used in the home and garden, and other research has demonstrated links between exposure to pesticides and endocrine disruption and neurological problems. Mothers exposed to pesticides during pregnancy can pass these toxins to the developing fetus with profound consequences.

NCAP in Eugene, OR is spearheading an Inerts Disclosure Campaign. Information can be obtained by emailing info@pesticide.org or calling 541-344-5044.

Pesticide Action Network North America (PANNA) Pesticides Database
www.pesticideinfo.org
PANNA created this project to compile information on human toxicity, ecotoxicity and regulatory information for roughly 6,400 pesticide active ingredients, which is integrated with the US EPA database of information on consumer pesticide products.

The Best Control
