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...

Cadmium and lead contamination of vegetables produced in rural areas of Bursa Province, Turkey, was found to be less contaminated than vegetables grown close to heavy traffic and industrial activities. The highest levels of cadmium and lead were found in lettuce; the lowest levels in vegetables were found in leeks. The lead levels in spinach grown in traffic areas were at least twofold higher t...

Efficient implementation of an environmental biomarker requires multi-annual comparability over a wide geographical range. The present study improved the comparability of a quantitative competitive metallothionein (MT) enzyme-linked-immuno-sorbent-assay (ELISA) in the sentinel fish Lithognathus mormyrus by introducing to the assay recombinant MT and beta-actin standards. Commercial antibodies f...

ABS11tACT: A study to measure the heavy metal pollution level in the sediment of coastal and offshore area indicates that high concentration of heavy metals were found around Manora channel and eastern coast of Karachi. In comparison with coastal areas, relatively low concentration of heavy metals was recorded in the offshore area. The result shows that sewage and industrial wastes are the main...

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...

Estimating standard-exceeding probabilities of toxic metals in soil is crucial for environmental evaluation. Because soil pH and land use types have strong effects on the bioavailability of trace metals in soil, they were taken into account by some environmental protection agencies in making composite soil environmental quality standards (SEQSs) that contain multiple metal thresholds under diff...

Heavy metals are major contributors to pollution of the biosphere, and their efficient removal from contaminated water is required. Biosorption is an emerging technology that has been shown to be effective in removing very low levels of heavy metal from wastewater. Although peptides such as metallothioneins or phytotchelatins are known to immobilize heavy metals, peptide-based biosorbents have ...

Background. The existence of toxic metallic elements in the environment is one of the most important factors influencing the metabolism of calcium. The aim of our study was to compare the incidence of osteoporosis in Upper Silesia to the level of environmental pollution with lead, cadmium, zinc, and copper. Material and methods. An epidemiological data base gathered by the Silesian Branch of th...

Purpose. The problem of heavy metal Cd pollution in the soil is still very serious. widely used treatment measure situ passivation chemical remediation technology. Some studies have shown that single application phosphate or silicate can control cadmium pollution, but few been conducted on effect thermal activation temperature nano and silicate-combined transformation form soil. Materials metho...

The main objective of this study was to evaluate the contamination by mercury (Hg), methylmercury (Me-Hg), cadmium (Cd), selenium (Se), zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn) in dolphins stranded on the French Mediterranean coast. The distributions of these contaminants in the organs of dolphins have also been studied. Overall, contamination levels varied according to the followin...
