Effects of acute experimental pollution by lead on some haematological parameters in Carassius carassius (L) var. auratus

Several haematological (RBC; WBC and thrombocyte count, HGB, HCT, MCV, MCH, MCHC) and serological parameters (lead blood content, ALA-D, glucose, GOT, GTP, Try, Chol, TP, Na+, K+, Cl-, Ca++) have been assayed in specimens of Carassius submitted to sublethal acute exposure to lead(5ppm, 24 and 48 hrs). The following differences were observed between control and treated samples: the number of RBC was decreased after 48 hrs of treatment; haematocrit, haemoglobin percentage and MCHC were also decreased. Glucose and lead concentrations in blood were increased whereas ALA-D, transaminases and calcium were decreased. No significant variations in the other studied parameters were observed.
