I.L. Golovanova, G.A. Urvantseva. Effects of lead on glycosidase activity in intestinal mucosa in fish // Transactions of Karelian Research Centre of Russian Academy of Science. No 5. Experimental biology. 2014. Pp. 195-199
Keywords: glycosidases, digestion, fish, heavy metals, lead.
The effects of in vitro exposure to lead ions Pb2+ at concentrations of 0.01–25 mg/l on the activity of intestinal mucosa glycosidases in fish with different feeding spectrum – planktophagous blue bream Abramis ballerus (L.), benthophagous bream Abramis brama (L.), roach Rutilus rutilus (L.), white-eye bream Abramis sapa (Pallas), ichthyophagous pike-perch Sander lucioperca (L.) and wels catfish Silurus glanis L. were investigated. Low sensitivity of glycosidases to the effect of lead Pb2+ in the investigated fish species was shown. The highest inhibitory effect was observed in bream, the highest stimulatory effect – in blue bream at the 25 mg/l concentration of Pb2 + ions.
