This study highlights the behaviour of Mercury in the abiotic and biotic segments of the Mandovi-Zuari estuarine system. Spatial, seasonal (Premonsoon and Postmonsoon) and tidal, distribution of THg in dissolved/particulate fractions, sediment concentrations were mapped of the river mouths, Mormugao Port, inner and outer environs of this estuarine system. Observed seasonal partition studies pro...

Preliminary bioconcentration factors (BCFs) were determined of six tetrachlorobenzyltoluenes (TCBTs) in guppies (Poecilia reticulata). BCFs and rate constants were derived by an iterative integration method. With this method BCFs and rate constants can be derived from experimental data of a bioconcentration test, even if the concentration in the water is not constant and steady state has not be...

The terms bioaccumulation and bioconcentration refer to the uptake and build-up of chemicals that can occur in living organisms. Experimental measurement of bioconcentration is time-consuming and expensive, and is not feasible for a large number of chemicals of potential regulatory concern. A highly effective tool depending on a quantitative structure-property relationship (QSPR) can be utilize...

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 mg...

plant-based remediation (i.e. phytoremediation) is one of the most significant eco-sustainable techniques to cope with devastating consequences of pollutants. in the present study, the potential of a wetland macrophyt (i.e. potamogeton crispus ) for the phytoremediation of heavy metals (i.e. cu, cr, pb, as and cd) in the anzali wetland was evaluated. the results showed that p. crispus tends to ...

in the present study, a field study was performed on some herbaceous plants growing in thesoutheast of ahvaz, where some metal producing industries are active. the aim of this studywas to investigate and compare manganese (mn) and zinc (zn) accumulation in seven dominantherbaceous plants in this area. plant samples were collected randomly. associated soils weresampled from the same sites next t...

Bioconcentration of individual cedarwood oil constituents tested using an abbreviated dietary exposure in vivo test with internal benchmarking.

Contaminants of emerging concern (CEC) are a broad suite chemicals commonly found in the environment, aquatic organisms and even drinking water. They include pharmaceuticals, personal care products, industrial compounds added to consumer products. The CEC ammonium 2,3,3,3-tetrafluoro-2-heptafluoropropoxy propanoic acid, which is more known as generic name GenX, replacement common processing aid...

BCF1 (bioconcentration factor after the one day of exposition) value of BaP [benzo(a)pyrene] in strain A-8, Chlorella vulgaris Beijerinck 1890 (Chlorella BB) was studied. The algae were cultured in a modified Kiihl-Lorentzen liquid medium at room temperature, under continuous illumination and stirring for 24
