the present study has been undertaken in a laboratory scale to characterize and investigate pollution potential of textile effluents from depz area in dhaka, bangladesh. collected effluent samples from five different industries were analyzed for physico-chemical parameters using field kits and standard methods, and for metals using flame atomic absorption spectrophotometer (faas). the average p...

an emission factor is a tool that is used to estimate air pollutant emissions to the atmosphere. it relates the quantity of pollutants released from a source to some activities associated with those emissions. to determine the quantity of pollutant released from copper and its alloys smelting furnaces, 63 samples from emission gases were collected on cellulose ester membrane filters in three 8-...

rapid industrialization, installation of mega-desalination plants and suspected trace metals discharges in the kuwait marine environment instigated us to determine the trace metals toxicity on the body structures (first dorsal fin, otolith and scales) of the commercially relished mullet fish, liza klunzingeri. 96 h toxicity test with fe, cd, ni, as, showed the body structure of l. klunzingeri t...

Metallothionein (MT), a metal-binding protein induced primarily by heavy metals in vertebrates, is considered a biomarker for environmental heavy-metal contamination. To investigate heavy metal pollution in the freshwater environment, MT-I and MT-II were purified from livers of crucian carp (Carassius carassius) by gel exclusion chromatography and ion exchange chromatography. To detect the puri...

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 on the seawater front. It should be considered that me...

The relationship between plant species coexistence and soil microbial communities under heavy metal pollution has attracted much attention in ecology. However, whether plant species coexistence could offset the impacts of heavy metal combined pollution on soil microbial community structure and soil enzymes activities is not well studied. The modified ecological dose model and PCR-RAPD method we...

Constructing ponds to protect downstream ecosystems is a common practice in opencast coal mine reclamation. As these ponds remain integrated in the landscape, it is important to evaluate the extent of the effect of mine pollution on these ecosystems. However, this point has not been sufficiently addressed in the literature. The main objective of this work was to explore the metal pollution in m...

Heavy metal (Cr, Ni, Cu, Zn, Cd, and Pb) pollution, fractionation, and ecological risks in the sediments of Lake Chaohu (Eastern China), its eleven inflowing rivers and its only outflowing river were studied. An improved BCR (proposed by the European Community Bureau of Reference) sequential extraction procedure was applied to fractionate heavy metals within sediments, a geoaccumulation index w...
