Elevated levels of heavy metals in environmental compartments, such as aquatic soils, may pose a risk to human health due to their transfer in aquatic media and uptake by living organisms, thereby entering the food chain (Sin et al. 2001; Varol and Sen 2012).
A few species are found in freshwater or brackish environments, and a very few are non-aquatic soil-dwelling species (ref).
Dr. Fan not only contributed significantly to the production of penicillin in China but also established the broad framework for the effective use of microbes to develop sustainable agriculture by increasing agricultural production, creating valuable goods from agricultural wastes, cleaning up pollutants in aquatic and soil environments, and enhancing soil fertility through organic farming.
Oomycetes are a group of eukaryotic micro-organisms of the kingdom Stramenopila that exhibit a wide breadth of life styles from free-living saprophytes in aquatic and soil environments, to above ground endophytes and obligately biotrophic parasites of plants and animals [ 1].
The effects most frequently cited in the literature are damage to roadside vegetation (trees, shrubs, ground cover, grasses, wetland vegetation), water (surface water, ground water, rivers and streams, lakes and ponds, aquatic life), soil, wear and tear on roads, and corrosion of bridges and vehicles.
Further escape of these nanoparticles into the effluent will contaminate the aquatic and soil environment.
Then we present environmental concentrations of cyanotoxins in freshwaters and their fate in aquatic and soil ecosystems.
This article presents experimental designs focusing on assessing of the bioavailability of metals in aquatic organisms, soil organisms, microorganisms, plants, birds, and mammals.
These results should enable a more efficient design of nanoEHS risk assessment experiments by predicting the aquatic or soil compartments at greatest potential risk for accumulation of and exposure to citrate capped 20 nm AgNPs.
