Items in the home that could contain PCBs include printed newspapers and product packaging. Especially products with green, blue, and yellow dyes. Reduce the amount of PCBs entering the environment by purchasing dye-free products and avoiding products with excessive packaging. Use all natural products with the least amount of chemicals. Do not use printed materials and packaging in wood stoves or fire places. Products with the highest levels of PCBs tested include caulking for windows, sidewalks and bathrooms. When hiring service providers for home maintenance, like landscaping or cleaning, choose companies that manage and reduce their waste. Click here for a list of Envirostars-certified businesses.
