loss of capacity to elevate plasma cortisol in rainbow trout oncorhynchus mykiss treated with a single injection of o p Dichlorodiphenyldichloroethane
Environmental Toxicology and Chemistry, 2002Co-Authors: Sandrine Benguira, Vincent S. Leblond, Jean-philippe Weber, Alice HontelaAbstract:The organochlorine o,p′- Dichlorodiphenyldichloroethane (o,p′-DDD) is a metabolite of dichlorodiphenyltrichloroethane (DDT), known for its adrenolytic actions in birds and mammals. The effects of o,p′-DDD on the cortisol stress response were investigated in rainbow trout, Oncorhynchus mykiss, in a dose-response study in vivo. A dose-dependent decrease in plasma cortisol levels was observed on days 7 and 14 after a single i.p. injection of o,p′-DDD. Treatment with o,p′-DDD had no effect on weight gain, hematocrit, and gonado- or hepatosomatic index but decreased liver glycogen reserves. The results indicate that o,p′-DDD is an adrenotoxic compound in rainbow trout and that its effects can be detected even 14 d postinjection.

Short Communication LOSS OF CAPACITY TO ELEVATE PLASMA CORTISOL IN RAINBOW TROUT (ONCORHYNCHUS MYKISS ) TREATED WITH A SINGLE INJECTION OF o,p9-Dichlorodiphenyldichloroethane
2002Co-Authors: Sandrine Benguira, Vincent S. Leblond, Jean-philippe Weber, Alice HontelaAbstract:The organochlorine o,p9- Dichlorodiphenyldichloroethane (o,p9-DDD) is a metabolite of dichlorodiphenyltrichloroethane (DDT), known for its adrenolytic actions in birds and mammals. The effects of o,p9-DDD on the cortisol stress response were investigated in rainbow trout, Oncorhynchus mykiss, in a dose-response study in vivo.

Organochlorine pesticides in commercial Pacific salmon in the Russian Far Eastern seas: Food safety and human health risk assessment
Marine pollution bulletin, 2019Co-Authors: V. Yu. Tsygankov, O. N. Lukyanova, Margarita D. Boyarova, A. N. Gumovskiy, Maksim M. Donets, V.a. Lyakh, V.p. Korchagin, Yu.v. PrikhodkoAbstract:Abstract Concentration of organochlorine pesticides (OCPs) (α-, β-, γ- hexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT), Dichlorodiphenyldichloroethane (DDD), dichlorodiphenyldichloroethylene (DDE)) in four species of Pacific salmon (pink, chum, chinook, and sockeye) are presented. OCPs in salmon organs increased in the following order: muscle

Bioaccumulation of HCHs and DDTs in organs of Pacific salmon (genus Oncorhynchus) from the Sea of Okhotsk and the Bering Sea.
Chemosphere, 2016Co-Authors: O. N. Lukyanova, Margarita D. Boyarova, Vasiliy Yu Tsygankov, Nadezhda K. KhristoforovaAbstract:Concentrations of isomers of hexachlorocyclohexane (α-, β-, γ-HCH) and dichlorodiphenyltrichloroethane (DDT) and its metabolites (Dichlorodiphenyldichloroethane (DDD) and dichlorodiphenyldichloroethylene (DDE) were assessed in organs of the pink (Oncorhynchus gorbuscha), chum (Oncorhynchus keta), chinook (Oncorhynchus tshawytscha), and sockeye salmon (Oncorhynchus nerka), caught near the Kuril Islands (the northern-western part of the Pacific Ocean), in the Sea of Okhotsk and the Bering Sea. Pesticides have been found to accumulate in fish organs in the following: muscles

Persistent Toxic Substances in the Muscles and Liver of the Pacific Walrus Odobenus rosmarus divergens Illiger, 1815 from the Bering Sea
Russian Journal of Marine Biology, 2014Co-Authors: V. Yu. Tsygankov, Margarita D. Boyarova, O. N. LukyanovaAbstract:This study reports data on the contents of organochlorine pesticides and heavy metals in the muscles and livers of eight individuals (five males and three females) of the Pacific walrus Odobenus rosmarus divergens Illiger, 1815, which were captured in the summer of 2011 in Mechigmensky Bay of the Bering Sea. Pesticides, namely α-, β-, and γ-isomers of hexachlorocyclohexane (HCH), dichlorodiphenyltrichloroethane (DDT) and its metabolites Dichlorodiphenyldichloroethane (DDD) and dichlorodiphenyldichloroethylene (DDE), as well as the heavy metals Cd, Pb, and Hg were found in all samples studied. The total concentration of organochlorine pesticides in the muscles varied from 200 to 5700 ng/g lipid weight and in the liver from 4900 to 90300 ng/g lipid weight. The concentrations of cadmium, lead, and mercury were 0.04–6.7, 0.13–0.76, and 0.03–0.40 μg/g dry weight, respectively. On the whole, the contents of organochlorine pesticides and heavy metals in the organs of the Pacific walrus were lower compared to those in marine mammals from other regions of the World Ocean.
