Introduction: Severe industrial diseases result from the hepatic accumulation of mercury, cadmium or chromium in humans and on the other hand cadmium and dichromate and mercuric salts may induce lung or kidney cancer. Acute or chronic CdCl2, HgCl2 or dichromate administration induces hepatic and nephrotoxicity in rodents. Oxidative stress is often cited as a possible cause of metal induced cell...

The present investigation characterizes tannery effluents by determining water quality parameters and some selected trace metallic constituents in order to measure the magnitude of environmental pollution. Effluents and sediments have also been used to isolate chromium-resistant bacteria, collected from Hazaribagh area, Dhaka, claimed to be increasing Cr (VI)-enriched environments, and utilized...

This article presents the regularities of reduction sulfur, nitrate and nitrite ions by sulfur reducing bacteria Desulfuromonas sp., which were isolated from water man-made Yavorivske Lake (Lviv Region, Ukraine), under influence potassium dichromate. in process anaerobic respiration can use reduce different electron acceptors, such as nitrates, nitrites, oxidized forms heavy metals, particular,...

A moderate amount of information is available on coccidian parasites (Apicomplexa) of snakes of Oklahoma (McAllister et al. 1995, 2011, 2013), and, although another reptile from the state, the ground skink (Scincella lateralis) has been thoroughly surveyed (McAllister et al. 1994, 2014), nothing, to our knowledge, has been published on coccidia of any lizard in Oklahoma. Yet, Oklahoma supports ...

Chromium is a widespread industrial waste. The soluble hexavalent chromium Cr (VI) is an environmental contaminant widely recognized to act as a carcinogen, mutagen and teratogen towards humans and animals. The fate of chromium in the environment is dependent on its oxidation state. Hexavalent chromium primarily enters the cells and undergoes metabolic reduction to trivalent chromium, resulting...
