AB  - The elimination of persistent organic pollutants (POPs) obsolete pesticides 
      stockpiles, particularly the organochlorine pesticides (OCPs), is one of the 
      critical environmental issues faced by many developing countries. This pioneering 
      study aimed to investigate the occurrence, source fingerprinting, human health, 
      and ecological risks of OCPs in the surroundings of the lone POPs pesticide 
      destruction facility in Pakistan. The SigmaOCPs residual levels in soil ranged from 
      35.98 to 566.77 ng/g dry weight (dw), with a mean concentration of 
      174.42 + 111.62 ng/g (dw). The OCPs contamination levels in the soil followed the 
      pattern as 
      SigmaHCHs > Sigmaendrins > Sigmaendosulfans > dieldrin > Sigmaheptachlors > SigmaDDTs > Sigmachlordanes > methoxychlor. 
      The SigmaHCHs residual concentrations were comparatively higher than the previous 
      national and global soil studies. The recent accumulation of HCHs, DDTs, and 
      heptachlor was observed in the study area as identified by beta-HCH/ summation operatorHCHs, 
      (DDE + DDD)/SigmaDDTs, heptachlor/Sigmaheptachlor, and heptachlor exo-epoxide/heptachlor 
      ratios. The OCPs' lifetime carcinogenic risk through ingestion, dermal, and 
      inhalation exposure routes ranged from 1.65E-08 to 2.91E-07, whereas the 
      noncarcinogenic hazard quotient (HQ) ranged from 9.12E-05 to 1.61E-03. The risk 
      vulnerability among age groups was in the order: 
      adult > toddler > child > teen > infant. The calculated risk levels were within 
      an acceptable limit of one in a million (1 x 10(-6)) for carcinogenic risk and 
      HQ < 1 for noncarcinogenic risk. The current OCPs residual levels, especially 
      dieldrin and endrin, exhibited low to medium ecological risks when compared to 
      various worldwide limits. The upsurge of the OCPs' environmental contamination 
      levels over the years and consideration of the food chain transfer might amplify 
      the human health and ecological risks intensities.
