متن کاملCopper toxicity in ruminants: air pollution as a possible cause.
Pathological findings and liver and kidney analyses confirmed that cattle had died of chronic copper poisoning on a farm in the north-eastern Transvaal. This is the first known published record of chronic copper intoxication of cattle in southern Africa. An epidemiological study revealed that a source of copper was air pollution which could have arisen from a nearby copper smelting unit. Buffal...
متن کاملIodine nutrition and toxicity in Atlantic cod (Gadus morhua) larvae
Copepods as feed promote better growth and development in marine fish larvae than rotifers. However, unlike rotifers, copepods contain several minerals such as iodine (I), at potentially toxic levels. Iodine is an essential trace element and both under and over supply of I can inhibit the production of the I containing thyroid hormones. It is unknown whether marine fish larvae require copepod l...
متن کاملAcute toxicity of povidone-iodine (Betadine) in common carp (Cyprinus carpio L. 1758)
Organisms in aquatic environments are exposed to a number of pollutants such as pharmaceutical residues. As such, the aim of the present study is to achieve the Lethal Concentration (LC50) of Povidone-iodine (Betadine) for Cyprinus carpio. To do so, the study employs samples, weighing 4±1 [mean±SD] gr, and carries out an experiment in static condition. Based on OECD instructions, after a period...
