RESULTS: In Dongguan between 2002 and 2009 altogether 82 cases were reported, among the 82 cases 8 patients were dead with case fatality rate of 9.8%. among them there were 12 cases of poisionings(8 females ,4 males); 9 cases were classified as mild poisonings and the rest serious ones, among the 12 cases 3 patients were dead with case fatality rate of 25.0%; Dermatitis caused by TCE there were 70 cases (37 males and 33 females), among the 70 cases 5 patients were dead with case fatality rate of 7.1%. 11 persons (91.7%) were engaged in the job of cleaning and 1 (8.3%) in water gun, and they performed the job only for 3 days in shortest and for 450 days in longest. The cases were distributed in the jobs as the following: 29 (41.4%), 12 (17.1%), 8 (11.4%), 5 (7.1%), 4 (5.7%), cases respectively in the job of cleaning, parts hanging, board washing, painting, gun water sprying; a job duration of 1-50 d (27.4 days in average).
