Abstract
During 1981-1982 period analyses of organochlorurates HCH
(alpha, beta, gama)and DDT species were performed in Razelm
Sinoe fishing reservoirs. The bigger concentrations were
identified for HCH alpha (0.011-0.72 ppm) and HCM gama
(0.024-0.549 ppm). The values of HCM beta (0.002-0.037 ppm),
HCM gama (0.011-0.039 ppm) and DDT (0.032-0.486 ppm) species
were situated under the first mentioned compounds. An increase
of all the analysed organochlorurated species was observed
in winter-spring and spring-summer months. The increased
values are due to the water mass turnover, horizontal currents,
as well as to the drainage of irrigation waters.
