A greenhouse experiment has been planned for this study to delineate the benefits of two types of rice husk biochars (namely B300 and B600 which are prepared at 300°C and 600°C, respectvely) and coal fly ash (CFA), as soil amendments, for decreasing the amount of some heavy metals (like Pb, Cd, Ni, Cr, and Cu) as well as mobility and phytoavailability in an artificially-calcareous multi-element...

background: heavy metals tend to bioaccumulate in living organisms, and their accumulation has been a major concern. as mammals are known to excrete heavy metals via their bile, it seems to be very promising to analyse metal burdens of par-asites that infect the biliary tree such as liver flukes of the genus fasciola . the pre-sent study was carried out to evaluate f. hepatica and f. gigantica ...

background : heavy metals and pah s in flue gas have received considerable attention in recent years due to their mutagenic or carcinogenic properties. pah s are products of incomplete combustion of carbonaceous compounds at high temperatures. heavy metals are released into the ambient air from the same sources as those earlier mentioned for pah s . the present study was carried out to investig...

Orthodontic treatment of individuals with metal hypersensitivity is a matter of concern for the orthodontist. Orthodontic appliances contain metals like Nickel, Cobalt and Chromium etc. Metals may cause allergic reactions and are known as allergens. Reaction to these metals is due to biodegradation of metals in the oral cavity. This may lead to the formation of corrosion products and their expo...

background: contamination of the environment due to heavy metals is a major concern to human life and the environment. this study was conducted to investigate and quantify the copper and zinc concentrations in industrial estates soil in arak, iran. methods: four industrial estates were considered for the experimental design, including arak 1, arak 2, arak 3, and ghotbe sanaati. for preliminary ...

the use of fertilizers npk and amendments in sugar cane crops may change the heavy metalsconcentrations in soils, making them available for plants and, consequently, they can be transferred to thehuman food chain. this study describes the redistribution of heavy metals (cd, cr, cu, ni, pb and zn) in soils with sugar cane crops due to fertilizers npk and amendments at corumbataí river basin, são...

rodents are sensitive species to and proper monitors of heavy metals in the environment. the accumulation of copper (cu), zinc (zn) and chrome (cr) were measured by wet digestion method and using an icp-oes instrument in hair and liver of persian jird (meriones persicus) in darreh zereshk copper mine, yazd without considering the effects of surrounded mines. results indicated that the concentra...
