Safety evaluation of pesticide-proof materials for agricultural clothing using in-vivo test

摘要

Many agricultural workers ask the question, "What risk do I assume if I use pesticides around my work place?" The risk of potential chemical injury of farmer is determined by exposure and toxicity in the occupational environments. A few pesticide labels specify that a chemical-resistant protective suit is required when applying the pesticide. So far, according to the results of the agricultural health study, and what the effects of pesticide exposure are ongoing and essential element in the agricultural worker's body is not being found. The aims of this research were the evaluation on pesticide-proof effect through in-Vivo test and performances of pesticide protective materials; PU-coated nylon, water-oil repellent non-woven fabric based Sontara and Gore-Tex with Poly Tetra Floro Ethylene (PTFE). As shown in SEM observed the pesticide-residual state on the surface of three-types protective clothing specimens; before pesticide spraying, 3.5 hours after spraying, and after 1 time water-cleaning, the pesticide quantities of permeation and residue were detected little bit different states in each other specimens. This results determined that Sontara and Gore-Tex than PU-coated nylon tends to retain more pesticide residue, and Gore-Tex was detected as almost negligible amount of pesticide residue. In other words, regular farm work clothing materials made of light weight, tightly woven fabrics gives worker great protection. We could suggest that specialized liquid-proof, chemical-resistant industrial work-suit gives industrial work-suit much more, but worker might feel as physical and physiological comfort.
