Results Different concentrations of vinegar with different disinfection duration showed significantly different bactericidal effect on Staphylococcus, Escherichia and Candida albicans (F=6.89~156.83, P.05). The effect was better along with higher concentration and longer duration. The average kill rate against natural bacteria on hands was 0.9915±0.0032 after exposed to vinegar solution for 2 min. The average kill rate against natural bacteria on kitchenware, such as table top, chopping block, knife, cupboard, porcelain bowl and the surface of refreshing box of the refrigerator were all above 0.9720 when cleaning and polishing with vinegar solution for 10min. The bactericidal efficacy of vinegar against natural bacteria in room air was enhanced with fumigating duration prolonged (F=1212.13, 5024.46; P.05), while lowered when there were persons in it (t=5.08-30.48, P.05).

Results showed that there were significantly positive linear correlations between the toxic effects（probits of mortality and inhibition rate） of chlorpromazine on the two aquatic organisms and the concentrations of chlorpromazine, and the toxic intensity became higher as the exposure time increased. The LC50 values of chlorpromazine acting on Carassius auratus in 24, 48 and 96h were 1.11, 0.43 and 0.32mg·L-1, respectively; and its safe concentration for Carassius auratus was 19.5μg·L-1. The LC50 and EC50 （50% of the tested Daphnia magna inhibited） values of chlorpromazine acting on Daphnia magna in 24h were 0.65 and 0.57mg·L-1, and the LC50 and EC50 values in 48h were 0.36 and 0.28mg·L-1, respectively. Thus, chlorpromazine have high toxicity to Carassius auratus and Daphnia magna, and the latter is more sensitive to chlorpromazine.
