Dept of Applied Biology Ch emical Technology, The Hong Kong Polytechnic Univer ity, Hung Hom) Abstract: Clay oil and loamy oil w ere u ed to a e the impact of landfill leachate irrigation on the microbial bioma and activitie of enzyme in oil. T he impact w ere a e ed after oneyear landfill leachate irrigation, and the re ult how ed that all element deter mined, e pecially in N, P, K, and Na, compared w ith control treatment , w ere accumulated con iderably in oil, which ugge tied that longterm landfill leachate irrigation may re ult in oil alinization. T he microbial bioma in the oil irrigated with leachate that diluted with tap w ater by 50% wa higher than that irrigated with raw leachate, planting could improve the activity of microorgani m and re ult in higher microbial bioma . Th e oil enzyme di played the imilar pattern in activity, however, the greater inten ity of enzyme activitie w a accelerated in clay oil than in loamy oil. Tte t howed that the difference in all enzyme activitie between leachate ir rigated clay oil and the control w ere ignificant at = 0. 01, except for catala e and
