The Protective Role of Vitamin C on Heamatological (WBC and Hb) Alterations in Commom Carp During Chronic Toxicity of Lead Nitrate

Abstract

This investigation intended to assess the outcome of haematological factors (WBCs and Hb) on common carp (Cyprinus carpio) of weight around (80 – 120 g) being exposed to various doses of lead nitrate and the protective role of Vitamin C in response to lead nitrate changes were studied. Chemicals (or elements) known as heavy metals are discharged into the surrounding environment as a consequence of commercial and industrial use as well as leaks from landfills. They are water-soluble but not biodegradable, and they are frequently firmly bound to proteins and polypeptides, even if previous research has issued warnings. The aquatic ecosystem is still impacted by several activities, changing the temperature and posing health risks to fish. The aquatic ecology becomes unbalanced as a result of heavy metals. Several lead nitrate concentrations were applied to the fish, and after 24, 48, 72, and 96 hours, (percentage)% mortality was recorded. Throughout the current experimental period, seven distinct concentrations of lead nitrate was used to determine the LC50 of the substance and evaluate its effect on common carp mortality. The lead nitrate concentrations ranged between 10 and 60 mg/l, and each concentration's death rate was determined. Lead nitrate was found to have an LC100 of 60 mg/l. Therefore, it was determined that the acute 96-hour LC50 value for the common carp, the fish used in this experiment, was 35 mg/l (ppm).
