water via the respiratory surfaces such as gills and/or the skin),similar concepts are adopted for, while plants are generally considered in terms of accumulation from the chemical present in soil or in the air compartments. For the aquatic organisms, initial approaches were simple correlations (...
In India, rivers are the main sources of drinking water and irrigation. And noting that India is ranked 13thin terms of consumption of pharmaceutical products globally (Mutiyar et al.2018), it’s therefore not a surprise that several studies about the occurrence of PPCPs in some of the majo...
Tetrahymena pyriformisgrown axenically in an organic medium with dissolved concentrations of 0.05 mM to 3 mM gadolinium-chloride forms numerous Gd-containing particles (Fig.1, a-d, f + g, Tab.S1). Gd is taken up by the cells, processed intracellularly, and subsequently excreted into the ...
In terms of RNA analysis, blood compared favourably with muscle and liver and was technically simpler to work with. Reticulocyte enumeration by microscope was technically simple and provided excellent results. Due to its low requirement for equipment, this technique for growth determination has great ...
(eco-)toxicity studies17, as well as a bioindicator for heavy metal pollution18,19,20. The influence of heavy metals on ciliates was mainly investigated in terms of mortality, generation time and cytotoxicity. The main focus of research was on the heavy metals Cd, Cu, Zn and Pb17. There...
Despite the low concentrations of the contaminants in the sediment, significant amounts of PCBs were found in plankton, macro-invertebrates and fish. The composition of the PCB mixtures found in the various organisms cannot be explained in terms of simple partitioning of the PCB congeners between ...
Much experimental work in biouptake of either pollutants or nutrients by microorganisms has relied on the interpretation of the data in terms of steady-state theories Whitfield and Turner, 1979, Morel and Hering, 1993, Tessier et al., 1994, Stumm and Morgan, 1996 in which the kinetics consider...
The best general estimates of chemical concentrations in earthworms were generated by simple ln-ln regression models for As, Cd, Cu, Hg, Mn, Pb, Zn, and polychlorinated biphenyls. No method accurately estimated Cr or Ni in earthworms. Although multiple regression models including pH generated ...
Energy Dispersive X-ray analysis and X-ray Diffraction analysis to confirm uniform dispersion and entrapment of AgNPs within the matrixes. These valorized products were evaluated for their efficacy in detoxifying the ubiquitous and toxic hexavalent chromium (Cr6+) in aquatic environments, withAnabas tes...
