With less pesticide use, children would be healthier

Now that winter is finally winding to a close, pesticide season is

beginning. It's not just the pesticides the farmers use. It's the pesticides

we and our neighbors use on our lawns, our lakes, our pets and ourselves -

pesticides that find their way into air we breathe, the food we eat, the

water we drink, our homes and us.

They work their way deep into our systems, even into the breast milk of

nursing mothers. So along with precious nutrients, a nursing baby is likely

to get dieldrin, chlordane and heptachlor.

Pesticides are designed to kill, and the evidence grows daily that they kill

far more than their intended targets. They are especially toxic to fetuses

and children, whose developing systems cannot handle even the smallest

exposures to these poisons.

Pesticide exposure is linked to Parkinson's disease, endocrine disruption,

and cancers including leukemia, brain cancer and non-Hodgkin's lymphoma.

Children exposed to pesticides are at up to six times greater risk of

leukemia or brain cancer.

Yet we continue to dose our children with these poisons; at home, at school,

ball fields, golf courses, throughout our neighborhoods and at camp. Even if

we don't use them in our own homes or yards, we are exposed when our

neighbors do. Pesticides - in the form of lawn chemicals, mosquito

treatments or roofing preservatives - drift to our yards as easily as

leaves.

Some commonly used lawn pesticides evaporate and become airborne quickly,

especially when temperatures are high. The resulting vapors can drift up to

five or 10 miles. We breathe them. We track them inside to our carpets where

children play. We are exposed yet again when they leach into groundwater,

and from there, into the water we drink.

No one knows how many tons of pesticides are used in Minnesota. The

Minnesota Agriculture Department is required by law to collect data on

pesticide use, and to monitor and reduce contamination when detected. In a

November 2001 report, " Inaction Speaks Louder Than Words, " The Minnesota

Center for Environmental Advocacy (MCEA) found that the Agriculture

Department is not doing its job; that large portions of the state are

unmonitored; and that the agency fails completely to monitor for pesticide

breakdown products.

Further, the Agriculture Department bases its decisions on whether

contamination requires action on advice from a committee made up largely of

industry representatives.

The MCEA report cites numerous studies by state and federal agencies

documenting widespread low-level pesticide contamination of our groundwater

and surface water. The Agriculture Department's central Minnesota monitoring

network found the herbicide atrazine in 70 percent of its wells. A 1997 U.S.

Geological Survey reviewed dozens of studies conducted over 20 years in a

20,000-square-mile area of central Minnesota, concluding that pesticides in

rivers and streams in that region are " ubiquitous. " The Minnesota Department

of Health found residues of the insecticide chlorpyrifos in the urine of

almost all the Minnesota children tested and residues of 2,4-D in more than

half.

For a rough idea of your immediate exposure, look around your neighborhood

this spring for those little " Warning: Keep Off. Chemically Treated " lawn

signs that pop up.

This won't take into account people who treat their own lawns or lakes; who

spray for mosquitoes and bugs and milfoil and bees.

Bugs and weeds, dandelions and crabgrass are part of life. We don't have to

love them, but we do need to deal with them in ways that don't hurt our

children or ourselves. We need to reduce dependency on pesticides and

practice Integrated Pest Management. There are many resources, including the

Minnesota Office of Environmental Assistance, Gardens Alive at www.gar

densalive.com and the Health-E-Home at www.checnet.org.

As this halting winter disappears, we could have real seasons: spring,

summer and fall. But if we keep using pesticides, that's all we'll get.

Pesticide season. And for children, that can be lethal.
