“…Hence, management tools such as land sparing, i.e., high-intensity agriculture in defined areas to spare land for conservation in other parts, appear to be less plausible for freshwater biodiversity conservation than land sharing through extensive agriculture (22). Control of diffuse sources of pollution from agriculture remains a challenging task but can, for example, be achieved by implementing riparian buffer strips (especially edge of field), grassed paths, or vegetated treatment systems (23,24). Risk from other chemicals of concern relates mainly to point source pollution (e.g., input of waste water from households or industry), implying the requirement of optimized treatment technologies (e.g., ozonation; ref.…”

Organic chemicals can contribute to local and regional losses of freshwater biodiversity and ecosystem services. However, their overall relevance regarding larger spatial scales remains unknown. Here, we present, to our knowledge, the first risk assessment of organic chemicals on the continental scale comprising 4,000 European monitoring sites. Organic chemicals were likely to exert acute lethal and chronic long-term effects on sensitive fish, invertebrate, or algae species in 14% and 42% of the sites, respectively. Of the 223 chemicals monitored, pesticides, tributyltin, polycyclic aromatic hydrocarbons, and brominated flame retardants were the major contributors to the chemical risk. Their presence was related to agricultural and urban areas in the upstream catchment. The risk of potential acute lethal and chronic long-term effects increased with the number of ecotoxicologically relevant chemicals analyzed at each site. As most monitoring programs considered in this study only included a subset of these chemicals, our assessment likely underestimates the actual risk. Increasing chemical risk was associated with deterioration in the quality status of fish and invertebrate communities. Our results clearly indicate that chemical pollution is a large-scale environmental problem and requires far-reaching, holistic mitigation measures to preserve and restore ecosystem health.toxicity | effect thresholds | streams | river basins | ecological data

“…Pesticides used in agriculture present a particularly important environmental threat due to their ecotoxicity which stems naturally from their purpose (Reichenberger et al, 2007;Buchanan et al, 2011). MCPA, a systemic herbicide used for the post-emergence control of broad-leaf weeds (Tomlin, 1994), is such an example of an agricultural pesticide that is commonly found in waters and soil (Silva et al, 2006;Köck et al, 2010;Botta et al, 2012;Matamoros et al, 2012a).…”

H I G H L I G H T S• CW with LECA substrate and Phragmites plants tested with agricultural wastewaters.• High removals of TSS, COD, NH 4 -N, polyphenols, a pharmaceutical and a pesticide.• Contact time of wastewaters with beds ranged from 3 to 9days in batch conditions.• Promising results suggest more studies in full-scale and more realistic conditions. Constructed wetlands (CWs) are receiving a renewed attention as a viable phytotechnology for treating agricultural wastewaters and for the removal of more specific pollutants, in particular recalcitrant ones. In this work, the performance of CW mesocosms using light expanded clay aggregates (LECA) as the bed's substrate and planted with Phragmites australis was investigated for treatment of olive mill wastewater (OMW), swine wastewater (SW) contaminated with oxytetracycline and water contaminated with herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid). Both wastewaters (OMW and SW) initially presented high organic matter content and total suspended solids which were removed by the system with efficiencies higher than 80%. Removal of polyphenols in OMW and nitrogen compounds in SW also showed similar or higher efficiencies in comparison with other treatment systems reported in the literature. The antibiotic oxytetracycline was completely removed from SW within the assay period in unplanted LECA beds, but planted beds allowed a significantly faster removal. In regard to water contaminated with MCPA, the results showed that LECA has a large sorption capacity for this herbicide (removal efficiencies of 56-97%). In general, considerably higher pollutant removal efficiencies were obtained when plants were used (up to 28% higher). The results obtained are indicative that CWs with LECA as substrate may be an adequate option for agricultural wastewater treatment. a b s t r a c t a r t i c l e i n f o

“…Studies of pesticide sorption in agricultural wetlands show a similar dependence on contaminant hydrophobicity (Kruger et al, 1996;Moore et al, 2002;Reichenberger et al, 2007). For example, sorption of the herbicide atrazine (log K ow = 2.75) to soil, litter, peat, and sediments from three Midwest wetlands was well described for all sorbents by an organic carbon-normalized distribution coefficient (K OC = 760 L/kg OC) (Alvord and Kadlec, 1995).…”

Treatment wetlands have become an attractive option for the removal of nutrients from municipal wastewater effluents due to their low energy requirements and operational costs, as well as the ancillary benefits they provide, including creating aesthetically appealing spaces and wildlife habitats. Treatment wetlands also hold promise as a means of removing other wastewater-derived contaminants, such as trace organic contaminants and pathogens. However, concerns about variations in treatment efficacy of these pollutants, coupled with an incomplete mechanistic understanding of their removal in wetlands, hinder the widespread adoption of constructed wetlands for these two classes of contaminants. A better understanding is needed so that wetlands as a unit process can be designed for their removal, with individual wetland cells optimized for the removal of specific contaminants, and connected in series or integrated with other engineered or natural treatment processes. In this article, removal mechanisms of trace organic contaminants and pathogens are reviewed, including sorption and sedimentation, biotransformation and predation, photolysis and photoinactivation, and remaining knowledge gaps are identified. In addition, suggestions are provided for how these treatment mechanisms can be enhanced in commonly employed unit process wetland cells or how they might be harnessed in novel unit process cells. It is hoped that application of the unit process concept to a wider range of contaminants will lead to more widespread application of wetland treatment trains as components of urban water infrastructure in the United States and around the globe.
