Work Environment Factors and Their Influence on Urinary Chromium Levels in Informal Electroplating Workers

Abstract

One of the informal sector which absorbs labor was electroplating business. This sector uses chromium as coating material because it was strong, corrosion resistant and strong. Nonetheless hexavalent chromium is highly toxic if inhaled, swallowed and contact with skin. Poor hygiene, the lack of work environment factors and sanitation conditions can increase the levels of chromium in the body. This aimed of this study was to analyze the association between work environment factors and levels of urinary chromium in informal electroplating worker. A Purposive study was conducted in Tegal Central Java. The research subjects were 66 male workers. Chi Square analysis was used to establish an association between work environment factors and level of urinary chromium. There is a relationship between heat stress and wind direction to the chromium levels in urine (p <0.05), but there is no relationship between humidity and levels of chromium in the urine (p> 0.05). This explains that work environment factors can increase chromium levels in the urine of informal electroplating workers.
