Microbial observation in bioaccumulation of heavy metals from the ash dyke of thermal power plants of Chhattisgarh, India

Several mechanisms are developed by the microorganisms to tolerate few high concentrations of heavy metals. One of these mechanisms dependent upon anabolic and catabolic energy of microorganisms is the bioaccumulation of heavy metals. In present work, approximately four varieties of bacteria have been isolated from the ash dyke sample of …

Mercury exposure and antinuclear antibodies among females of reproductive age in the United States: NHANES

Immune dysregulation associated with mercury has been suggested, though data in the general population are lacking. Chronic exposure to low levels of methylmercury (organic) and inorganic mercury is common, such as through fish consumption and dental amalgams. The objective of the study was to examine associations between mercury biomarkers and …

New Technique Enhances Fuel Cell Efficiency and Removes Toxic Heavy Metal Ions

There may be a new method to enhance fuel cell efficiency. Scientists have created a new technique that not only ups efficiency, but also removes toxic, heavy metal ions. The direct methanol fuel cell (DFMC) has been a promising energy conversion device both for electric vehicles and portable devices. However, …

Roadside plants as bio indicators of air pollution in an industrial region, Rourkela, India

Foliar surface undergoes several structural and functional changes when particulate-laden air strikes it. An attempt was made to evaluate the quality of air in terms of respirable suspended particulate matter (RSPM), suspended particulate matter (SPM), sulphur dioxide (SO2) and nitrogen dioxide (NO2) along with biochemical parameters of twelve selected roadside …

Assessment of heavy metal contamination from municipal solid waste open dumping sites in Bangladesh

Co-disposal of the household orginated hazardous materials with municipal solid waste (MSW) into dumping sites is the usual practice in Bangladesh. In this paper, characterization of heavy metals in MSW in the open dumping sites in Bangladesh is presented.

Heavy metal pollution in Hunan soil exceeds China’s limits by 1,500 times

More than 1,500 times the permitted level of heavy metal has been found in soil in China’s south-central Hunan province, according to an unofficial environmental study. Among the heavy metals found in the soil, the amount of cadmium was 200 times more than that permitted by China’s soil environmental quality …

Marine invertebrates as bioindicators of heavy metal pollution

Atmosphere, earth and water compose the environment. The presence of heavy metals in the environment has grown because of their large employment in some industrial and agricultural activities. Although these metals are terrestrial products, they flow into the sea through effluents and sewage or are directly discharged from industries placed …

Chemical and microbial characterization of surface and ground waters near estuaries of East Godavari region for evaluation of their potential for application

Surface and ground water are systems linked with each other. In coastal region salanization problem is significant for groundwater contamination. The transition of ground water in to the surface waters contributes a noticeable change in teh ground water environment besides heavy metal cycling. Due to natural and anthropogenic activities the …

Conservationists slam plans to dump mining waste into Norwegian fjord

Norway’s green and unspoilt image is at risk if government agrees to Nordic Mining dumping hundreds of millions of tonnes of waste into a fjord, say campaigners Norway’s image as one of the world’s cleanest, greenest countries with some of the finest unspoilt scenery will be tarnished if the government …

Sunderbans' water getting toxic: Scientists

Climate change is causing toxic metals trapped in the sediment beds of the Hooghly estuary in the Indian Sunderbans to leach out into the water system due to changes in ocean chemistry, say scientists, warning of potential human health hazards. They predict that after about 30 years, increasing ocean acidification …

Urinary metals and heart rate variability: A cross-sectional study of urban adults in Wuhan, China

Epidemiological studies have suggested an association between external estimates of exposure to metals in air particles and altered heart rate variability (HRV). However, studies on the association between internal assessments of metals exposure and HRV are limited. The purpose of this study was to examine the potential association between urinary …

AIIMS study links air pollution, arthritis

Are autoimmune diseases such as rheumatoid arthritis, where the body’s immune system reacts against itself, linked to air pollution?
