ВЛИЯНИЕ ПОВЫШЕННЫХ КОНЦЕНТРАЦИЙ ИОНОВ Fe3+ В ВОДЕ НА СОДЕРЖАНИЕ ЖЕЛЕЗА И ТРАНСФЕРРИНА В ПЛАЗМЕ КРОВИ РЫБ
Исследовано содержание железа, общего белка и концентрацию трансферрина в плазме крови карпа (Cyprinus carpio L.) и щуки (Esox lucius L.) при действии 2 и 5 предельно допустимых рыбохозяйственных концентрации ионов Fe3+ в воде. Установлено, что повышенное содержание ионов железа в воде приводит к росту количества металла в плазме обоих видов рыб и увеличение показателя насыщения трансферрина железом. Данные показатели могут быть использованы для оценки загрязнения водной среды ионами Fe3+.

INFLUENCE OF ELEVATED CONCENTRATIONS OF Fe3+ IONS IN WATER ON THE CONTENT OF IRON AND TRANSFERRIN IN BLOOD PLASMA OF FISH
The content of iron, total protein and concentration of transferrin in the blood plasma of carp (Cyprinus carpio L.) and pike (Esox lucius L.) in the action of 0.2 and 0.5 mg/dm3 ions of Fe3+ in water corresponding to 2 and 5 fisheries maximum permissible concentrations (MPC). It has been established that the content of total protein in blood plasma is significantly increased only with the action of 5 MPC concentration of Fe3+ ions in carp. It was noted that the content of iron and transferrin in the blood plasma of carp increased following the effects of both investigated concentrations of Fe3+ ions. The maximum index of saturation of transferrin by iron in carp was noted for the effect of 2 MPC of Fe3+ ions. Quantitative characteristics of binding of iron to pork blood transferrin by the influence of increased concentrations of ferric ions in water were different from carp. The maximum accumulation of iron with blood plasma of pike per 0.5 mg/dm3 Fe3+ ions is noted. However, in the blood of pike there was a decrease in the amount of transferrin in the action of 2 and 5 MPC of ions of the ferrum (III). It was established that proportional to the concentration of Fe3+ ions in water, the index of saturation of transferrin by iron increases, which can testify to the toxic effect of metal ions and lead to pathological changes in the organism of fish. In general, the studied parameters can be used to assess the pollution of the water environment with Fe3+ ions.
