research articles on cadmium toxicity in animals

As per the recommendation of the National Research Council of the United States (1980) the Cd content of forage crops should not be more than 0.5/zg g-~ in order to limit the concentration of Cd in the liver and kidney of animals feeding on these crops to protect humans against cadmium toxicity through concentration of these organs. Nephrotoxic effects of cadmium exposure are well established in humans and experimental animals. Among the heavy metals, it is considered most serious metal contaminant since the occurrence of Itai- Itai disease in Japan [1]It is a non-essential highly toxic heavy metal having half-life of ten to thirty years [2]Cadmium is toxic at , very low exposure levels Cadmium is also associated with hypercalciuria and nephrolithiasis. The toxicity of dissolved cadmium to a variety of marine animals has been found to be related to salinity, with decreased toxicity observed at higher salinities. Acute toxicity testing were carried out the freshwater swamp shrimp, Macrobrachium nipponense, as the model animal for the semiconductor applied metals (gallium, antimony, indium, cadmium, and copper) to evaluate if the species is an suitable experimental animal of pollution in aquatic ecosystem. This study aimed to analyse the protective effects of quercetin on the toxicity of cadmium (Cd) using metabonomics techniques. Cadmium is a heavy metal of considerable toxicity with destructive impact on most organ systems. However, no attention has been paid so far to explore its renoprotective activity in animals and human beings, therefore the present paper reports protective effect of Spirulina platensis on cadmium induced renal toxicity in Wistar rats. Pulmonary toxicity. Cadmium, chromium, and lead accumulation in aquatic plants and animals near a municipal landfill. It is, however, agreed upon that exposure causes lung cancer. 23, No. heart of cadmium exposed animals [24]. (2017). in lead and cadmium toxicity and its ameliora tion, ” Ve t e r i n a r y Medicine I nternational , vol. Materials and methods Animals Cadmium, represented with symbol Cd, is a heavy metal with a high toxicity. An early manifestation of such toxicity is calciuria a few hours after injection of CdMT in rats. 2, pp. The research is not clear on whether chronic cadmium inhalation causes pulmonary toxicity. Human and Ecological Risk Assessment: An International Journal: Vol. Musculoskeletal toxicity [11] A. Cuypers, M. Plusq uin, T . Despite such results of various cadmium toxicities in animal studies, data from human studies are lacking and insufficient to support the cause-effect relationship. It is widely distributed in humans, the chief sources of contamination being cigarette smoke, welding, and contaminated food and beverages. Exposure to cadmium primarily occurs through the ingestion of contaminated food and water and, to a significant extent, through inhalation and cigarette smoking. 2011, Article ID 457327 , 2011. Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals. It is naturally occurring in the environment as a pollutant that is derived from agricultural and industrial sources.
