We conducted a study in Indonesia, to assess chemical exposures in electronic industry, measuring participatory study and biological parameters platform. A convenience participant of 36 employee (28 exposed, 8 controls) was selected, and urine samples were collected before and after shifts. Five solvents (acetone, methyl ethyl ketone, toluene, benzene, and xylenes) were found in 46%-97% of tests, and seven metals (arsenic, cadmium, cobalt, tin, antimony, lead, and vanadium) were identified in 60%-100% of tests. Biological parameters observing and participatory study reported value in evaluating staffs’ poisoning when factory air evaluating is not proper due to a insufficiency of concern  from head of company.
