Archives of environmental protection 2012 v.38 no.1 pp. 83-96
ISSN:
2083-4810
Subject:
aluminum; aquatic organisms; exchangeable aluminum; ion exchange; mineralization; ponds; risk; sediments; spectrophotometers; statistical analysis; toxicity
Abstract:
... Water and bottom sediment samples collected from a few fish-breeding ponds/reservoirs were subjected to tests. The aim of this paper was to determine the total content of aluminium and its fractions in the samples tested to estimate the potential risk to fish caused by the toxic forms of aluminium. The monomeric inorganic aluminium in waters was determined using the ion exchange and extraction-col ...

Abstract:
... It is unknown whether metal absorption efficiencies in terrestrial soft-bodied species can be predicted with the same metal properties as for aquatic species. Here, we developed models for metal absorption efficiency from the dissolved phase for terrestrial worms and several aquatic species, based on 23 metal physicochemical properties. For the worms, the absorption efficiency was successfully rel ...

Abstract:
... With the widening application of graphene oxide nanosheets (GONS), their safety has attracted much attention. Secretions from aquatic organisms are ubiquitous in natural water, but the effects of secretions on the characteristics and toxicity of GONS remain largely unknown. To help fill this knowledge gap, we characterized the GONS with biological secretions (GOBS) and the associated changes in ap ...

Subject:
adsorption; aquatic organisms; electrochemistry; food chain; heavy metals; humans; ion exchange; oxidative stress; pollution; rapid methods; sanitation; toxicity; voltammetry
Abstract:
... In aqueous systems, heavy metal ions, when present in excess than permissible limits, are dangerous for human beings and aquatic life. Heavy metals cannot be degraded. Rather, they accumulate in living organisms either directly or through the food chain. Inside the body, metal ions can be converted to more toxic forms or can directly interfere with metabolic processes. As a result of metal toxicit ...
