ABSTRACT 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 four thermal power plants of Chhattisgarh, i.e. , Bharat Aluminium Company (BALCO), Chhattisgarh State Electricity Board (CSEB), Korba, Thermal Power Cooperation (NTP...

ABSTRACT Turkey’s inland water ecosystem consists of 33 rivers (177.714 miles), 200 natural lakes (906.118 ha), 159 reservoirs (342.377 ha) and 750 ponds (15.500 ha). Sedimentological studies conducted on inland water ecosystems during the last 15 years in Turkey can be categorized into two main topics. The first group of studies is concerned with heavy metal levels in sediment, with especial reference to the interaction between water, sediment and aquatic organisms. Additionally, the studies in question deal with the potential impacts of heavy metal concentrations on the ecosystem. The second group of studies is concerned with the role of eutrophicatio...

ABSTRACT In order to decrease the content of heavy metals in the crops soils, a novel method based on using an aqueous solution bearing cysteamine as the key ingredient was studied to extract the polluted heavy metals including Cd, Cu, Zn, Ni and Pb. By using the single-factor method, remediation-related technical index were screened and they are, respectively, applied to the solid material whereby the heavy metals are released and extracted from the ...

ABSTRACT The influence of essential (Cu, Ni and Zn) and non-essential heavy metals (Hg, Cr, Pb and Cd) on seed germination and early seedling growth in industrial oil crop Crambe abyssinica was evaluated under laboratory conditions. Our results indicated that among the 7 heavy metals tested only Cu and Hg significantly (P < 0.01) decreased Crambe seed germination in a dose-dependent manner at higher concentrations while certain Cr concentrations...

ABSTRACT Proximate and heavy metal analysis of five instant noodles samples was carried out using standard analytical methods. The proximate analysis showed the presence of moisture content (3.65% - 7.80%), ash content (1.11% - 5.50%), fat content (13.64% - 18.69%), crude protein content (0.167% - 0.202%), crude fibre content (1.00% - 9.25%) and carbohydrate content (63.68% - 79.72%). All esse...
