AB  - Comprehensive air and surface soil monitoring was conducted for new and legacy 
      organochlorine pesticides (OCPs) to fill the knowledge and data gap on the 
      sources and fate of pesticidal persistent organic pollutants (POPs) in the 
      Sultanate of Oman. DDTs in agricultural soil samples ranged from 0.013 to 
      95.80 ng/g (mean: 8.4 +/- 25.06 ng/g), with a median value of 0.07 ng/g. The 
      highest concentration was observed at Shinas, where intensive agricultural 
      practice is prevalent. The dominance of p,p'-DDT in soil and air reflected 
      technical DDT formulation usage in Oman. Among newly enlisted POPs, 
      pentachlorobenzene had the maximum detection frequency in air (47%) and soil 
      (41%). Over 90% of sites reflected extensive past use of hexachlorobenzene. Major 
      OCP isomers and metabolites showed net volatilisation from the agricultural soil, 
      thereby indicating concurrent emission and re-emission processes from the soil of 
      Oman. However, the cleansing effect of oceanic air mass is the possible reason 
      for relatively lower atmospheric OCP levels from a previous study. Although DDT 
      displayed maximum cancer risk, the level is below the permissible limit. DDT 
      primarily stemmed from obsolete stock and inadequate management practices. Hence, 
      we suggest there is a need for DDT regulation in Oman.
