The discoveries, distributed in February in the diary Relevant Ecological Science affirmed buildups of DDT, Lindane, Heptachlor furthermore, Dieldrin, Endrin in every one of the specimens.
Human harming from Aldrin and Dieldrin is described by major body writhings. Heptachlor is profoundly harmful to people and can be retained through the skin, lungs and the nourishment tract.
These chemicals are banned in many nations and in Kenya by the Pest Control Products Board. The study drove by Dr Isaac Omwenga, appeared Lindane and DDT as the most predominant in every one of the specimens investigated.
“While the contamination did not breach international health safety standards, it is an extremely worrying trend,” Dr Laetitia W. Kanja of the University of Nairobi and one of the study authors said.
“The issue of chemical residues must first be addressed maybe through non-leaching ponds and caveat on dangerous chemicals or both,” says Dr Kenneth Wameyo a consulting veterinary surgeon in Nairobi.
DDT residue was found in all tested fish body parts including muscle and liver with the highest concentration found in the brains. The head usually reserved for those with best fish eating skills is considered most nutritious.
“Our evidence suggests recent use of DDT in the study area hence more strict control measures against the use of this chemical need to be put in place,” wrote Dr Omwenga and his team.
