AB  - South-west coast of India has a history of using pesticidal persistent organic 
      pollutants (POPs) particularly endosulfan until aerial spraying was banned during 
      early 2000. Since soil acts as a repository for such pesticidal persistent 
      organic contaminants, we have monitored residues of seventeen organochlorine 
      pesticides (OCPs) in the surface soil samples from the agricultural, coastal, and 
      backwater transects along the south-west coast of India. OCPs concentration in 
      soil were in the order agricultural > coastal > backwaters transects. Endrins, 
      hexachlorocyclohexane (HCH) and heptachlors were among the dominant OCPs 
      quantified in this study. Dominance of metabolites such as 
      dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD) and 
      endosulfan sulfate indicates past usage. All the OCPs were dominant in the 
      agricultural transect where plantations/agricultural activities are prevalent. In 
      some specific sites, traces of HCH isomers showed ongoing usage of technical HCH 
      in those sites contradicting the ban in agricultural sector. Backwater sites 
      which are background locations showed positive correlation between soil organic 
      carbon and soil borne OCPs thereby indicating an aged source possibly due to the 
      short/long atmospheric transport from the site of application. Based on the 
      policies regarding control, prevention and other measures for the management of 
      pesticides in Kerala, it was concluded that the implementation on the ground 
      level and the legal framework should be strengthened to prevent further illegal 
      use of the banned pesticides.
