AB  - Two fish species of tilapia, <I>Tilapia guineensis</I> and 
  <I>Sarothorodon melanotheron</I> were sampled from Lagos Lagoon and Agboyi Creek 
  between December, 2008 and September, 2009 during the dry and wet seasons. They 
  were analysed for organochlorines: aldrin, dieldrin, endrin, DDT, heptachlor, 
  HCH, endosulfan, chlordane and methoxychlor. The muscle tissues and organs of 
  the fishes were subjected to cold extraction and clean-up. The detection and 
  determination of the organochlorine residues were performed using a gas chromatograph 
  with a <SUP>63</SUP>Ni electron capture detector. All the fishes had condition 
  factor &gt;1. The organochlorine residues in the fishes in Lagos Lagoon were 
  more than the level in Agboyi Creek while a higher concentration of the residues 
  was observed during the dry season. The muscle tissues of the female fishes 
  accumulated higher organochlorines than the muscle tissues of the male fishes. 
  <I>Tilapia guineensis</I> accumulated higher residues in Agboyi Creek while 
  <I>Sarothorodon melanotheron</I> accumulated higher residues in Lagos Lagoon. 
  The order of accumulation of residues was gills&gt;livers&gt;small intestines&gt;kidneys&gt;muscles. 
  Except for endrin and heptachlor, the estimated daily intakes of the organochlorines 
  were within the acceptable daily intakes while the levels of residues in the 
  fishes were within the permissible residue limits.
