BACKGROUND Failed hip prostheses can cause elevated circulating cobalt and chromium levels, with rare reports of fatal systemic organ deposition, including cobalt cardiomyopathy. Although blood cobalt and chromium levels are easily measured, organ deposition is difficult to detect without invasive biopsy. The T2* magnetic resonance (MR) method is used to quantify tissue iron deposition, and pla...

We have studied the effect of simultaneous oral treatment of aqueous garlic extract (Allium sativum) on heavy metal (nickel II and chromium VI) induced changes in serum lipid profile. Nickel sulfate and potassium dichromate treated rats showed a significant increase in serum low density lipoprotein-cholesterol (LDL-C), very low density lipoprotein-cholesterol (VLDL-C) and triglyceride (TG) leve...

Human activities like mining, transport, agriculture, industrial waste disposal and military actions release inorganic pollutants in high concentrations that are toxic to natural ecosystems. Heavy metal pollution causes potential ecological risk. Heavy metals like Cadmium (Cd), Lead (Pb) and Chromium (Cr) when present in high concentrations in soil exert potential toxic effects on overall growt...

This study focused on the accumulation of heavy metals (Couper, Nickle, Cobalt, chromium) in the edible tissues of Crucian. Sampling was done in 3 stations (West, Center, and East) of Anzali wetland in 2012. In this study, 10 samples were collected from each site in the standard weight by gill net fishing method and measuring the concentration of heavy metals was performed using flame atomic ab...

This research involved the synthesizing of a reactive polymer, long alkyl quaternized poly(4-vinylpyridine) (PVP), and coating it on the surface of silica gel to produce a granular sorbent to remove Cr(VI) from water. Batch experiments were conducted to determine the kinetics, sorption isotherm, pH effects, and influence of other anions on the chromium adsorption onto the coated silica gel. The...

An overview is presented of classic and more recent applications of liquid chromatography for the analysis of metal species. The different approaches involving ion-exchange, ion-pair, and chelation separation mechanisms are discussed as well as the new philosophy of simply removing interferents before specific detections of metal ions (alkali and alakaline earths, rare earths, heavy and transit...
