Garages and auto-repair workshops may be polluted with other heavy metals besides lead. Blood of autoworkers with high lead content was analysed for cadmium, chromium, copper manganese, nickel, ALAD activity and carboxyhaemoglobin level. Cadmium and copper levels in blood of autoworkers were comparable with those of the control subjects while chroimium and nickel levels were significantly highe...

the effect of different levels of zinc and copper organic supplements on performance, plasma copper plus zinc status, serum alkaline phosphatase (alp), ceruloplasmin (cp) activity as well as vitamin ¬a concentration was studied in 25 mehraban male lambs each of 5-6 months of age and 30/64±3/47kg of live weight. the following five dietary treatments were used: 1) control (base diet with no addit...

BACKGROUND AND AIMS Excessive production of reactive oxygen metabolites (ROMs) by phagocytic cells is thought to contribute to the mucosal pathology of Helicobacter pylori infection. Previously, H pylori infection was shown to have a differential effect on some gastric mucosal scavenger enzymes of ROMs-namely, mitochondrial and cytoplasmic superoxide dismutases-reflected by a large increase in ...

The prion protein (PrP) has been shown to bind copper. In the present study we have investigated whether prion disease in a mouse scrapie model resulted in modification of metal concentrations. We found changes in the levels of copper and manganese in the brains of scrapie-infected mice prior to the onset of clinical symptoms. Interestingly, we noted a major increase in blood manganese in the e...

Trace metal contamination is a global health issue. This study evaluated boxed and loose-leaf tea from Bangladesh using Handheld X-ray Fluorescence (XRF) analyzer for lead other metals to rapidly screen as potential hot spot of heavy exposure. Of the 33 elements measured, several priority pollutants were below limit detection (LOD) in all samples, including (LOD 2.17 mg/kg) arsenic 1.68 mg/kg)....

Introduction The cause of a significant number of miscarriages remains unexplained. There is a need to identify the potential role of environmental, dietary and lifestyle factors in the risk of pregnancy loss. The present study was the first to investigate the content of miscarried embryonic material with respect to eight metals (aluminium, cadmium, chromium, copper, manganese, nickel, lead and...

Siddha system specifies medicinal plants containing various metal constituents for curing ailments. The plants reported as copper containing were subjected to atomic absorption spectrophotometic analysis. Among these mangifera indica and coccinia indica were found to contain comparatively higher content of copper while manganese was move in coccinia indica aloe perfoliata, cassia auriculata and...

The flocculation of dissolved heavy metals is a process which has an important effect on decreasing the concentration of the colloidal elements during estuarine mixing of river water and sea or ocean water. During this important process, a large amount of colloidal elements change into particles in the form of flock and the dissolved loads decline. This study is performed to evaluate the mechani...
