Two multidimensional chromatographic methods for enantiomeric analysis of o,p ′-DDT and o,p ′-DDD in contaminated soil and air in a malaria area of South Africa
Abstract(#br)In rural parts of South Africa the organochlorine insecticide DDT (1,1,1-trichloro-2,2-bis( p -chlorophenyl)ethane) is still used for malaria vector control where traditional dwellings are sprayed on the inside with small quantities of technical DDT. Since o,p ′-DDT may show enantioselective oestrogenicity and biodegradability, it is important to analyse enantiomers of o,p ′-DDT and its chiral degradation product, o,p ′-DDD, for both health and environmental-forensic considerations.
