Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2013, Vol 6, Issue 2
Abstract
In the present study, fat tissues of small cyprinid fish was sampled from Cluj-Napoca and Cluj surrounding areas (N-W of Romania), urban and peri-urban waters, and used to determine the organochlorine and total polychlorinated biphenyls (PCB) concentrations of aquatic environments. Results indicated a very low concentration or even the absence of some organochlorine pesticides and PCB, as follows: DDT and metabolites 0.005, Aldrin 0.001, Dieldrin 0.000, Endrin 0.000, Hexachlorbenzen 0.002, Heptachlor 0.001, α-HCH=0.000, β-HCH=0.000, γ-HCH=0.007, δ-HCH=0.000, total PCB=0.000. Such low concentrations of pollutants found in fish fat are explained by decreased agricultural and industrial exploitation in Romania, banning the use of some dangerous chemicals in agriculture, short generation time of fish and its low position in the trophic chain.
