Cupriavidus sp. HMR-1 was isolated from a heavy metal-enriched culture of activated sludge from a wastewater treatment plant in Hong Kong. Here, we release the HMR-1 genome to provide basic genetic characteristics for a better understanding of its multiple heavy metal resistance properties.

Characterized by moderate and almost unchanging microbial growth, stability is an essential aspect ofcompost quality Low growth rates give benign organisms a competitive advantage over pathogens such as Sulnronellu and &fhrurn, which thnve m high-growth-rate conditions (Inbar et al., 1990). Also, stability prevents nutrients from becommg tied up in rapid microbial growth, allowing them to be av...

This Communication describes a prototype quantitative paper-based assay that simultaneously measures the levels of Pb(2+) and Hg(2+) in water. The assay requires only measurements of time to yield a quantitative readout, and the results are independent of sample volume, humidity, and sample viscosity.

introduction: heavy metals released from stationaryand mobile origins can be transported in water, air and soil and can be even absorbed by plants, animals and human bodies. trace elements are currently of great environmental concern. nowadays, one of the most important environmental problems is pollution of agricultural soils occurs by heavy metals due to human activities. atmospheric subsiden...

the heavy metals concentrations including zinc, copper, lead and cadmium (zn, cu, pb and cd) in water and sediments in gorgan bay and their accumulation in rutilus frisii kutum, acipenser persicus, rutilus rutilus caspicus and cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. there was substantial increase in concentration of heavy metals ingoing from the water to the ...

Introduction The potential oncogenic effect of some heavy metals in people occupationally and non-occupationally exposed to such heavy metals is already well demonstrated. This study seeks to clarify the potential role of these heavy metals in the living environment, in this case in non-occupational multifactorial aetiology of malignancies in the inhabitants of areas with increased prevalent en...

Anthropologic activities have transformed global biogeochemical cycling of heavy metals by emitting considerable quantities of these metals into the atmosphere from diverse sources. In spite of substantial and progressive developments in industrial processes and techniques to reduce environmental emissions, atmospheric contamination by toxic heavy metals and associated ecological and health ris...
