Comparison of Landfill Leachate Properties by LPI and Phytotoxicity-A Case Study

The formation of leachate is one the inevitable consequences associated with operation landfills. In addition to study physicochemical composition, toxicity an important parameter taken into account, among others because need subject treatment before discharge environment. aim this was determine degree contamination using LPI and index. An analysis relationship between toxic effect on plants calculated values also carried out assess whether they could provide a measure when selecting method. research conducted Calculated pollution index showed that leachates from selected Polish landfills are characterized by low medium levels values. variation in obtained particularly evident active closed related composition leachates. value ranged 7.4 11.1, while 12.9 15.9. inactive Phytotoxicity tests at concentrations can promote plant growth. At higher (50 100%), caused inhibition root shoot growth, which correlated high results confirmed values, so it be considered as reliable indicator toxicity.
