“…These results are particularly worrisome since in this catchment, the family farmers cultivated tobacco following strictly the instructions of a technological pack established by the international tobacco industry. It involves application of high doses of phosphate fertilizers and high amounts of pesticides, increasing then the risk of contamination of watercourses (Yahia and Elsharkawy, 2014;Guo et al, 2014).…”

“…Intensification of agriculture for increasing food production has led to the degradation of soil and water resources during the last several decades (Comino et al, 2015;Erkossa et al, 2015;Seutloali and Beckedahl, 2015;Taguas et al, 2015). Modern and intensive agricultural practices expose the soil to the erosion and accelerate the transfer of sediment to the lower parts of landscape and into water bodies, along with contaminants such as pesticides (Magnusson et al, 2013;Yahia and Elsharkawy, 2014) and phosphorus (Poulenard et al, 2008;Dodd et al, 2014;Dodd and Sharpley, 2015). In agricultural catchments with high run-off coefficients and sediment yields, as in Southern Brazil, erosion process needs to be controlled to prevent an irreversible degradation of soil and water quality (Didoné et al, 2015;Merten et al, 2015).…”

Tracing Sediment Sources Using Mid‐infrared Spectroscopy in Arvorezinha Catchment, Southern Brazil

The widespread adoption of the sediment fingerprinting approach to guide catchment management has been limited by the cost and the difficulty to prepare and process samples for geochemical and radionuclide analyses. Spectral properties have recently been shown to provide a rapid and cost‐efficient alternative for this purpose. The current research objective was (i) to quantify the sediment source contributions in a 1∙19‐km2 rural catchment of Southern Brazil by using mid‐infrared (MIR) spectroscopy and (ii) to compare these results with those obtained with geochemical approach and near‐infrared and ultraviolet–visible spectroscopy methods. The sediment sources to discriminate were cropland surface (n = 20), unpaved roads (n = 10) and stream channel banks (n = 10). Twenty‐nine suspended sediment samples were collected at the catchment outlet during nine significant flood events. The sources could be distinguished by MIR spectroscopy. Cropland and channel bank sources mainly differed in their clay mineral contents, but their similar organic matter content complicated the MIR‐model predictions. Unpaved road contributions were discriminated from the other sources by their lower organic carbon content. When the results of the current research based on MIR spectroscopy are compared with those obtained using other sediment fingerprinting approaches, based on geochemistry and near‐infrared and ultraviolet–visible spectroscopy, an overestimation of channel banks contribution and an underestimation of cropland and unpaved road contributions is found. These results suggest that MIR spectroscopy can provide a useful tool that is non‐destructive, rapid and cheap for tracing sediment sources in rural catchments and for guiding the implementation of soil and water conservation measures.

“…Organic wastes also settle out on the bottom of the stream, altering the characteristics of the substratum. Organic pollutants have been detected in marine organisms, including the green mussel, Perna viridis [87][88][89][90], barnacles [91], odontocete species [92] and fish species [58][59][60][61]93].…”

Heavy metals and organic pollutants are ubiquitous environmental pollutants affecting the quality of soil, water and air. Over the past 5 decades, many strategies have been developed for the remediation of polluted water. Strategies involving aquatic plant use are preferable to conventional methods. In this study, an attempt was made to provide a brief review on recent progresses in research and practical applications of phytoremediation for water resources with the following objectives: (1) to discuss the toxicity of toxic chemicals pollution in water to plant, animals and human health (2) to summarise the physicochemical factors affecting removal of toxic chemicals such as heavy metals and organic contaminants in aqueous solutions by aquatic plants; (3) to summarise and compare the removal rates of heavy metals and organic contaminants in aqueous solutions by diverse aquatic plants; and (4) to summarise chemometric models for testing aquatic plant performance. More than 20 aquatic plants specie have been used extensively while duckweed (L. minor), water hyacinth (Eichhornia crassipes), water lettuce (P. stratiotes) are the most common. Overall, chemometrics for performance assessment reported include: Growth rate (GR), Growth rate inhibition (% Inhibition), Metal uptake (MU), translocation/transfer factor (TF), bioconcentration factor (BCF), Percent metal uptake (% MU), Removal capacity (RC) and Tolerance index (TI) while absorption rate have been studied using the sorption kinetics and isotherms models such as pseudo-first-order (PFO), pseudo-second-order (PSO), Freundlich, Langmuir and Temkin. Using modeling and interpretation of adsorption isotherms for performance assessment is particularly good and increases level of accuracy obtained from adsorption processes of contaminant on plant. Conclusion was drawn by highlighting the gap in knowledge and suggesting key future areas of research for scientists and policymakers.
