industrial wastewaters are of the major sources of heavy metal pollution in the environment. in the middle east, gas and oil industry is the major source of heavy metal pollution and releases significant amounts of metals into the terrestrial and aquatic environment. in this research the capability of the common reed ( phragmitis australis ) in absorbing heavy metals cd, pb and v from the waste...

The present study was conceptualized to evaluate the heavy metal absorbing potential of microbes isolated from paper industry effluent. The effluent was used as the source sample, after screening morpho-metrically ten strains were cultured and sub cultured to achieve the pure discrete colonies. Out of ten discrete colonies two were found to have the heavy metal absorbing ability. These two bact...

BACKGROUND Although ageing workers face specific health and safety concerns, conflicting evidence exists regarding the effects of age on workplace injury rates and workers' compensation claims. AIMS To examine injury and workers' compensation claim rates by age and injury type in an aluminium smelter over a 9-year period. METHODS Routinely collected data for workplace injuries and workers' ...

The Moravian-Silesian Region is one of the most polluted sites by dust particles in the Czech Republic. Therefore, atmospheric concentrations of heavy metals as cadmium, cobalt, chromium, copper, nickel, lead, antimony, thallium, manganese, iron and zinc, were monitored at 10 localities in the region during summer of 2014. Heavy metals were monitored in 10 particle size classes from 18.3 nm to ...

AIM To investigate the disability due to musculoskeletal disorders of the upper extremities in heavy industry workers. METHODS The population under study consisted of 802 employees, both white- and blue-collar, working in a shipyard industry in Athens, Greece. Data were collected through the distribution of questionnaires and the recording of individual and job-related characteristics during ...

OBJECTIVES Little information is available on the quantitative risks of respiratory disease from quartz in airborne dust in the heavy clay industry. Available evidence suggested that these risks might be low, possibly because of the presence in the dust of other minerals, such as illite and kaolinite, which may reduce the harmful effects of quartz. The aims of the present cross sectional study ...

Several electroplating industry including agricultural sector industries, sewage treatment and mining operations all combine to generate hazardous waste water containing enormous amounts of toxic heavy metals. The accumulation of toxic heavy metals in human beings and animals cause many metabolic disorders. Heavy metal concentration was estimated in sewage, sludge and electroplating wastewater ...

Until recently the electrical power industry has relied solely on traditional technologies copper and iron as cables, transformers and machines as the mainstream solution for the generation, transmission and distribution of power. Whilst use of these materials and technologies is here to stay, improvements in power semiconductor technology mean that the industry is moving into a position where ...

This article describes new approach of modern potentiostat systems for the determination of lead in solders used in electrotechnic industry. It was studied electrochemical detection methods to enable accurate detection of heavy metals. With regard to the requirements of these methods are proposed facility presented. The general aim is principles of quantitative heavy metal detection by the elec...
