Whenever it's possible, have your children eat organic foods-best for reducing the risk from pesticides. Try shopping at a farmer's market, where prices are lower

Peel and/or wash fruits and vegetables to help remove residue of contaminants

If you are pregnant or might be soon, limit tuna consumption to about 6 ounces a week to reduce exposure to mercury

Before and during pregnancy and breastfeeding, avoid fish (like swordfish, shark, and halibut) from water that might be contaminated with mercury.

Pesticides:

For pest removal in the home and garden, use nontoxic products or rely on alternative techniques, like planting plants that keep bugs away or sealing cracks and crevices in your home.

Lead:

.Have your kids, water, and home (if built and painted prior to 1978) checked for lead

.Run your tap water for two minutes each morning to get rid of water that may be contaminated from leaded solder in water pipes

.Get a professional to remove lead from your house; if this is not possible, make sure your children's hands and toys are frequently washed, wipe surfaces and floors regularly with damp cloth, and cover lead-painted surfaces with wallpaper, tiles, or paneling.

Alternative nontoxic cleaning products:

Replace toxic cleaning products with ingredients such as

.Borax for cleaning and dishwashing, disinfecting laundry, removing mold and mildew, and protection from ants.

.Baking Soda for deodorizing, cleaning drains, metal polishing, and cleaning ovens

.Vinegar for cleaning drains, glass, and metal, and for removing mold and mildew

.Washing Soda for cleaning, dishwashing, and laundry

.Soap for cleaning, dishwashing, and laundry.

Alternative household practices:

.avoid dry cleaning, which uses solvents-ask your local cleaner about alternative wet cleaning processes

.use nontoxic, vegetable-based paints, stains and lacquers

.never buy aerosol cans.

To reduce pesticides, support policies that emphasize using the least toxic chemicals and/or utilize Integrated Pest Management techniques (a plan for nontoxic strategies to get rid of pests)

Request advance notice of the use of pesticides at the school to protect your child from exposure.
