Exposure lawn care

The distribution of body weights was assumed to be a normal distribution with mean 70 kg and a 20% coefficient of variation (i.e., a standard deviation equal to 14kg). The amount of exposure for a body part was a PHED-based distribution, depending on the body part and the type of user, as well as the type of herbicide formulation used. The herbicide formulations were granule (G) formulated with fertilizer and used by homeowners for residential lawn care flowable formulation (FF), which is among the formulations classified as emulsifiable concentrate (EC) in PHED and water-dispersible granule (WDG).

Everyone in the United States has been exposed to low levels of chlordane. A more relevant question is whether or not you may have been exposed to high levels of chlordane. Before its ban in 1988, you might have been exposed to high levels of chlordane if you worked in the manufacture, formulation, or application of chlordane. Therefore, farmers and lawn-care workers may have been exposed to chlordane before 1978, and pest control workers may have been exposed to chlordane before 1988 by skin contact and breathing dust and vapor. A national survey conducted from 1980 to 1983 estimated that 3,732 workers were potentially exposed to chlordane in the United States. This number of potentially exposed workers should have decreased after chlordane s use was banned in the United States. However, the ban on chlordane did not eliminate it from your environment, and some of your opportunities for exposure to chlordane continue. 

Estimates are that 5,000 employees of lawn care companies created SZ of Che 80 million lawns in Che USA in 1980. Pesticides most used include preemergent grass weed, broadleaf weed and insect control pesticides. Applicators applying these pesticides are exposed for periods of six to eight weeks. Heasurements made Co determine exposure showed long term exposure resulted in very low levels of pesticide inhalation. Also, pesticide concentrations reaching the...

Everything we put down the drain or flush (down the commode) ends up in our watersheds which can affect the health of terrestrial and aquatic wildlife, plants, the atmosphere, and the water quality in our area. Residential and commercial use of chemicals constitutes a very large, nonpoint source of environmental contamination. A typical source of environmental contaminants are products used for household use such as cleaning agents, surfactants, pesticides, fertilizers, lawn and garden treatments, paints, sealants, and even discarded or flushed medicines. It is imperative that those seeking a healthy lifestyle and reduction in pollutant exposure choose with care the products they use to clean and maintain their homes, yards, and pets.
