Abstract

This study was executed to elucidate the degree of satisfaction with working environment and the factors affecting it for workers who are engaged in the composting plants with livestock manure in the Han-river watershed. As an evaluation on site, we applied the self-administered questionaire including general characteristics, working conditions, degree of satisfaction with working environment, and degree of satisfaction with working condition. Simultaneously, we analysed the exposure levels of odor (ammonia, hydrogen sulfide, and odor intensity) in the boundary area of plants. As a result of the study, health condition, odor, work load, dust, and smoking were proved to be the main factors affecting the degree of satisfaction with working environment for workers who are employed in the composting plants with livestock manure in the Han-river watershed. Of them, it was investigated that health condition, odor, and work load accounted for 61.3% of the total degree of satisfaction with working environment and health condition(p$<$0.01), odor(p$<$0.05), work load(p$<$0.05), and dust(p$<$0.05) were statistically significant. It was concluded that the degree of satisfaction with working environment was high for the workers who had good health status and low for the workers who had the relatively considerable work load and were often exposed to odor and dust. Therefore, to increase the degree of satisfaction with working environment for workers who are engaged in the composting plants with livestock manure, the measures that can reduce the exposure levels of odor and dust emitting from the composting plant with livestock manure should be improved.

본 연구에서는 한강유역에 위치한 축분퇴비공장의 작업환경 조사를 위한 현장 평가로서, 설문조사 및 악취물질 측정을 통해 근로자들의 작업환경 만족 수준과 이에 영향을 주는 요인들을 규명하였다. 연구결과, 축분퇴비공장 근로자들의 작업환경 만족도에 영향을 주는 요인들로 일반 건강수준, 악취, 작업량, 분진, 흡연으로 조사되었으며, 이 중 일반 건강수준, 악취, 작업량이 전체 작업환경 만족도의 61.3%를 대변하는 것으로 나타났다. 통계적 유의성을 나타낸 작업환경변수로는 일반 건강수준(p$<$0.01), 악취 작업량 분진(p$<$0.05) 등 이었다. 결론적으로 일반 건강수준이 높은 근로자일수록 작업환경 만족도가 높았으며, 작업량이 상대적으로 많고 악취와 분진에 쉽게 노출된 공장의 근로자일수록 작업환경 만족도가 낮은 것으로 분석되었다. 흡연을 하는 근로자는 작업환경 만족도가 낮게 나타냈으나, 통계적 유의성은 없는 것으로 분석되었다. 따라서 한강유역 축분퇴비공장 근로자들의 작업환경 만족도를 제고시키기 위해서는 공정 중 악취와 분진농도의 발생을 저감시켜야 할 것으로 판단된다. 그러므로 축분퇴비공장의 악취 및 분진농도의 발생을 최소화할 수 있는 처리공정 및 관리체계 정립이 시급하며, 이는 궁극적으로 축분퇴비공장 작업자의 건강 뿐만 아니라 주변 마을 정주민의 생활환경개선효과를 유발할 수 있다.
