ABSTRACT

Toxicities of waste samples taken from landfill site and waste water samples taken from
outlet of sewerage system were investigated. Eluates were prepared for the waste
samples taken from landfill. In order to determine toxicities of waste eluate and
wastewater three different biotests namely Thamnotoxkit FTM , Daphtoxkit FTM,
Protoxkit FTM were employed. Test results were expressed as LC50 for Thamnotoxkit
EC50 for Daphtoxkit and Protoxkit. Physical and chemical caracteristics of wastes and
wastewater samples were also determined and relation between physical and chemical
parameters of the waste and waste water sample with toxicity results were evaluated.
Reference tests were carried out with K2Cr2O7 to check the test procedures prier to the
analyses with samples. Sample toxicity results were reported as Toxic Units (TU) and
sensitivities of each test for each type of samples were determined.
