Some nickel compounds may enter human?s body and induce health impairment among exposed workers. Results of studies
indicate that blood and urine chemical concentrations as a result of occupational exposure are associated with the hygienic
behaviour of workers. The study was conducted in a nickel processing plant in Indonesia. The aim of the study was to evaluate
the influence of changes in hygienic behaviour on nickel exposures, and to assess the effectiveness of three worksite education
strategies aimed to reduce occupational nickel exposure. A quasi-experimental study was conducted to improve the hygienic
behaviour and to evaluate the effectiveness of worksite health education intervention programs. The study subjects were grouped
into three groups according to the type of intervention program implemented: 1) booklet only 2) booklet and lectures on nickel
exposures 3) booklet, lectures and a feedback. During the study the concentrations of air dust and urine and blood nickel
concentrations were measured. The study results demonstrated a significant increase in the aspects of knowledge, behaviour and
attitude among workers during the post intervention assessment when compared with the pre intervention period with the highest
improvement established among the third intervention group which included booklet, lectures and a feedback. Furthermore, the
study established a significant difference in urine and serum nickel concentrations between pre and post intervention. The study
outcomes showed that improvement in hygienic behaviour was associated with reduced serum and urine nickel concentrations
among exposed workers.
