  • Ida Bagus Putra Manuaba

Abstrak

This is an expost facto study with Analytical Cross Sectional Study design, within two
step activities, i.e. field study in order to gain sampling zone and obtaining sample needed.
Followed by laboratory works in order to obtain pesticide residual contamination on water.
Sample preparation for this purposed was carried out following a standard method. Gas
chromatography was employed in order to gain the pesticide contaminant.
Positive organochlorine pesticide contaminant, i.e. DDT and chlorotalonile were
observed from 55 sampling point of sediment taken from 5 sampling zone. DDT in the
sediment is 13.6 ppb with still bellow the maximum level of 42 ppb. Chlorotalonile in
sediment is 12.3 ppb. There is no threshold value of chlorotalonile, however, this
contamination still bellow the RfD 15 ppb and ADI 30 ppb (PIP, 1995; Caroline, 1997).
