Abstract

BACKGROUND: The personal protective equipments (PPEs) is the most important factor for reducing the pesticide exposure during the preparation and spraying of pesticides. This study was to investigate the retention, repellence and penetration of protective clothing of PPEs according to the ISO 22608 'Liquid penetration resistance-pipette test. Protective clothing for agriculture worker is very important for their health. However, test method for measurement of protective clothing is not presented in Korea. METHODS AND RESULTS: In order to measure the retention, repellence and penetration of protective clothing, a apparatus for pipette method in accordance with the ISO Guideline was prepared. The test was conducted at $25{\pm}5^{\circ}C$, $60{\pm}10%$ of relative humidity and pipette applied to a apparatus was validated to take exact amount(0.2 mL). The retention, repellence and penetration of five types of protective clothing and one type of shirt were analyzed by GC/MS. Pendimethalin(5% a.i, emulsion) was used as a test pesticide to measure above factors. The retention were less than 11.0% with the exclusion of two types(F4 and shirt) and the repellency was more than 67.0% with the exclusion of shirt material. The penetration was less than 5.4%, however, that of shirt was 66.7%. CONCLUSION: This results indicated that all protective clothing were suitable to use as PPEs according to the criteria specified by ISO Guide 22608. However, shirt was not suitable due to high penetration. This test method established for measurement the retention, repellence and penetration of protective clothing will help to establish the test notice of pipette method.

본 연구에서는 방제복의 액체침투저항성을 측정하는 방법 중 피펫법을 적용하여 국내 시판중인 5종의 방제복과 일반 shirt에 대해서 체류성, 발수성 그리고 침투성을 측정하였다. ISO 22608 Guideline 'Liquid penetration resistance-Pipette test'에서 요구하는 장치를 사용하였고 시험농약으로는 pendimethalin을 처리하여 GC/MS로 분석하였다. 5종의 방제복은 침투성이 0.0~5.4%로 매우 낮은 침투성을 보였으며 발수성은 67.0~98.1%로 농약이 쉽게 투과되지 않고 물 또는 액체에 의해서 제거될 수 있을 것으로 보였지만, 일반 shirt는 높은 침투성과 낮은 발수성이 확인되어 농약살포 시 손쉽게 피부에 노출될 수 있을 것으로 확인되었다. 현재 국내에서는 방제복에 대한 침투저항성 측정법과 기준이 마련되어 있지 않기 때문에, 본 연구는 방제복의 성능측정의 기준시험법 마련에 도움을 줄 수 있을 것으로 사료된다.
