The effects of lead on sera glucose, protein and cholesterol concentrations and on hematocrit
levels of Anguilla anguilla exposed to 0.06 and 0.12 ppm lead were studied over 15 and 30
days. Sera parameters and hematocrit levels were determined by spectrophotometric and microhematocrit methods, respectively. No mortality was observed during the experiments. Sera
glucose and protein levels showed a linear increase and a decrease respectively under the effect
of lead. Sera cholesterol levels decreased compared to control over 15 days of exposure to both
concentrations and this decrease was not significant between the concentrations on day 30.
Lead concentrations 0.12 ppm lead did not cause any variation in hematocrit level, while 0.06
ppm lead increased it compared to control.. Changes...
Effects of 1 mgL-1
cadmium (Cd) and 1 mgL-1 Cd-10 mgL-1
chitosan(CT) mixture on hematocrit levels, erythrocyte numbers and on
erythrocyte and erythrocyte nucleus areas were determined after exposing the animals to Cd and Cd-CT mixture over 7, 15 and 30
days. Microhematocrit and microscopic methods were used in determining the above blood parameters. No mortality was observed
during the experiments. Hematocrit levels and erythrocyte numbers decreased whereas erythrocyte and erythrocyte nucleus areas
increased in fish exposed to Cd alone compared with the control. No difference was observed, however, in the parameters studied in
Cd-CT exposed fish compared with the control, except the erythrocyte nucleus area (P
