Abstract |
A method was developed for the determination of two volatile pesticides, chloropicrin and ethylene dibromide, in wastewaters. The methods development program consisted of; a literature review; determination of the extraction efficiency for each compound from water into cyclohexane; and determination of suitable gas chromatographic analysis conditions. The final method was applied to two representative wastewaters spiked at appropriate levels in order to determine precision and accuracy of the method. For a wastewater sample spiked with 5 micrograms/l of chloropicrin and ethylene dibromide, the recoveries were 98 + or - 12 percent and 69 + or - 6.7 percent, respectively. For a wastewater spiked at 50 micrograms/l of chloropicrin and ethylene dibromide, the recoveries were 98 + or - 3.3 percent and 108 + or - 4.8 percent, respectively. Method detection limits (MDLs) for the two compounds in distilled water were 0.84 micrograms/l for chloropicrin and 0.20 micrograms/liter for ethylene dibromide. MDLs in wastewaters may be higher due to interfering compounds. |
