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...

Brassinosteroids play a significant role in the amelioration of various abiotic and biotic stresses. In order to elaborate their roles in plants subjected to heavy metals stress, Chlorella vulgaris cultures treated with 10(-8) M brassinolide (BL) were exposed to 10(-6)-10(-4) M heavy metals (cadmium, lead and copper) application. Under heavy metals stress, the growth and chemical composition (c...

ría and coastal zone are, in particular, vulnerable to heavy metals pollution. concentrations of 10 metals in liver, muscle and kidney of the sole (solea vulgaris) from ría of vigo and its coastal zone (spain) were measured from april 2006 to february 2007 and the relationships between fish size age and metal concentrations in the tissues was investigated. concentrations of the heavy metals in...

ABSTRACT Cemeteries are potential sources of groundwater contamination and, despite the several studies that evidence this sort contamination, only a few consider how aspects and characteristics unsaturated zone interfere in process. This study evaluated quality areas two cemeteries under same precipitation regime, climate burial practices, but with pedological differences. During one year, phy...

Studies on toxicities and tolerances of cadmium (Cd), copper (Cu), lead (Pb) and zinc (Zn) in the brown alga Isochrysis galbana and in the green-lipped mussel Perna viridis were conducted by short-term bioassays using endpoints growth production and mortality, respectively. The 5-day EC(50) and 24-h LC(50) of these heavy metals were determined in the brown alga and mussel, respectively. The EC(...

In order to understand the heavy metals accumulation and transfer in a plant-soil system in sewage sludge applied soils, 15 familiar garden plants (including 7 herbages, 5 shrubs and 3 arbor species) were planted in soil with sewage land application at the experimental site in Shanghai, China. The experiment measured the changes in 7 heavy metals (Zn, Cu, Ni, Cd, Pb, Cr and As) fractions and co...

landfill leachates are potential threats for environmental degradation. this study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in kolkata, india using leachate pollution index. the results of the physico-chemical ...
