Pesticides usage may damage our environment or even influence the human’s health. There are two major highly pesticide exposed groups including the farmers and the workers who use the pesticides. The major problem is that they usually let their skin contacted with pesticides. According to the literature reviews, protection clothings could reduce the risk of pesticide exposure. Because the protective clothings are not very comfortable, the workers don’t wear them so often.
The goal of this study is to recommend the workers to wear protective clothings with comfort and safety for the improvement to human’s health. This study uses three kinds of pesticides and ten types of fabrics. This experiment is divided into two methods. Firstly the absorption, repellency, and penetration of pesticides is studied by “Proposed ASTM Standard Method”. Another study includes the laundering, abrasion, and light exposure of fabric contaminated with pesticides using GC analytic method.
Results show that general fabrics can protect most part of skin, but their small openings and depth affect the pesticide’s penetration. The protection of fabric reduces the risk to 30 %. The fabrics of Hi-sett® which is light and cheap can be a good protection clothing with high quality.
The simulation of pesticide workers using fabric is applied to conduct abrasion, laundering, and light exposure against pesticides. The results show that the fabric absorption is increased by abrasion before it is damaged. More pesticides retain in the fabrics that may reduce the contact between pesticides and skin. Laundering and light exposure may effectively remove the pesticides in the fabrics.
