This report addresses the challenges encountered and, to a certain extent, overcome, while health risk assessment and management were being conducted in Mae Sot, Thailand following cadmium contamination to rice, the main diet of Thais. In November 2003, Department of Agriculture (DOA), Ministry of Agriculture (MOA) sent a summary report of a 6-year study revealing serious contamination of cadmi...

The resistance patterns of Pseudomonas aeruginosa strains isolated from freshwater and seawater to different antimicrobial agents and heavy metals were studied. It was found that resistance in these environments is linked to the level of faecal pollution. All strains were resistant to ampicillin and tetracycline but sensitive to carbenicillin, amikacin, tobramycin, and colistin, and to the assa...

In recent years, soil heavy metal pollution has caused serious harm to human beings and the environment. Phytoremediation become main means of remediation because its advantages such as low cost, obvious effect secondary pollution. this paper, status quo cadmium in China mechanism phytoremediation were summarized.

Background: Pollution of aquatic ecosystems with heavy metals leads to decrease of the biodiversity and accumulation of toxicants in the food chain. Species of the genus Scenedesmus are sensitive indicators of environmental changes and have been used for the evaluation of risk factors for contamination of aquatic ecosystems. The microalga Scenedesmus incrassatulus can remove chromium and cadmiu...

BACKGROUND To identify adverse renal effects due to air pollution derived from a cement plant in Korea. Urinary n-acetyl-B-glucosaminidase (U-NAG) levels in residents living near a cement plant were compared to those in a group who lived farther away from the plant. METHODS From June to August 2013 and from August to November 2014, laboratory tests for U-NAG and heavy metal were conducted on ...

heavy metals, e.g. cd and pb emit and release into the environment during cement production and are deposited into soils. this research was carried out to determine the concentration and spatial distribution of trace elements in top soils around the kurdistan cement factory, west of iran in order to evaluate the effect of cement factory on the environment. twenty-four soil samples were collecte...

soil contamination in the vicinity of the abandoned lakan lead and zinc mine was studied. the results showed that over the past decades, the environmental pollution was caused by lead, zinc tailings dam and acid mine drainage. the average of lead, zinc, cadmium, copper and nickel is 1295, 4273, 27, 185 and 92 mg/kg, respectively in the soils of tailings dam. these metals were continuously dispe...

Marine pollution has been studied under the following groupings of effects; harm to living resources, hazards to human health, reduction of amenities and interference with other users of the sea. This paper is concerned mainly with the first two categories and their interrelation. Apart from certain seabirds affected by oil, the major stocks of marine animals show no evidence of reduction by po...
