Toxicological studies on cadmium chloride as an environmental pollutant

Summary:-Cadmium salts are considered significant water pollutant notonly because of their direct toxicity in water, but also due to theirability to be concentrated and incorporated into the food chain byaquatic organisms and plants.Our study aimed to investigate various effects of cadmiumchloride and the rule of concurrent zinc exposure hoping toameliorate the hazardous effects of cadmium chloride on stray dogs.The experiment done on thirty eight stray dogs classified into sixsubgroups. The first two subgroup, A & B received 248.8 ppm indrinking water along two and four months. C and D subgroups,received concurrent treatment with zinc chloride by 124.4 ppm indrinking water beside the above cadmium dose along two and fourmonths. The mature dogs contained subgroup E which received only2.5 mg/L water cadmium chloride and subgroup (F) which received1.25 mg zinc chloride/L water plus above cadmium dose daily alongtwo months the other animals left as control on tap. water.Blood samples were taken from treated and non treated dogsevery fifteen days for investigatinghaematological and biochemicalpicture along the experiment. After two and four months bloodpressure and electrocardiograph pattern were recorded in dogsamples from each group.
