Heavy metal is widely used in industries and presents as a problematic environmental pollution. Some heavy metals, especially lead and mercury, are well described for their occupational and environmental intoxication whereas the other minor heavy metals are less concerned. In this article, the author will present the details of occupational and environmental minor heavy metal intoxication. This...

The present investigation has been conducted to understand the hazardous effect of sublethal concentration of cadmium chloride solution (0.8ppm on the histology of the liver of the fish Channa striatus for a period of 45 days. The histopathological changes induced in the liver were cytoplasmic vacuolization of the hepatocytes, blood vessel congestion, inflammatory leucocytic infiltration and ne...

Since the quality of sperm is affected by water industrial or agriculture pollution, sperm motility was measured as a sensitive and accurate bioindicator of water quality. In this study, sperm motility was measured by a computer assisted sperm analysis after 24 hours exposure of sperm to different concentration of heavy metals) Cadmium and Zinc). The results show that the sperm motility was not...

INFLAMMATORY BOWEL DISEASES AND AIR POLLUTION (Abstract). Air pollution is responsible for the increase in mortality, morbidity and a high number of hospitalizations for respir atory and cardio-vascular diseases. Recently, several studies have shown that air pollution can also affect the digestive system. The major impact was observed on inflammatory bowel diseases (Crohn’s disease and ulcerati...

BACKGROUND The environmental pollution is one of the factors contributing to the decrease of sperm quality for human beings. The aim of this study was to assess cadmium (Cd), chromium (Cr), and copper (Cu) concentration of man in environmental pollution site, and explore relationships between men exposure to Cd, Cr, and Cu and semen-quality parameters in environmental pollution site. METHODS ...

Soil pollution by metal(loid)s resulting from rapid economic development is a major concern. Accurately estimating the spatial distribution of soil metal(loid) pollution has great significance in preventing and controlling soil pollution. In this study, 126 topsoil samples were collected in Kunshan City and the geo-accumulation index was selected as a pollution index. We used Kriging interpolat...

Direct emission of cadmium into air and water in Japan has been controlled on the basis of the Emission and Effluent Standards. Environmental quality in these media has been improved, but delayed effects of these emissions in the past are now manifest by contamination of agricultural acreage in various parts of this country. Special land improvement projects are therefore required, and cost all...

Metals are being utilized of ways in industries and agriculture; particularly heavy metals such as Mercury, Lead, Arsenic and Cadmium constitute a significant potential threat to human health because they are associated to many adverse effects on health. Due to the increasing pollution, concentrations of various chemical compounds have increased in aquatic environments. Water contaminants have ...
