“…Effects on microbial communities are mainly related with the alteration of the soil structure and with the decrease of osmotic potential (Chowdhury et al, 2011;Sarig et al, 1993;Torsvik and Ovreas, 2002;Wong et al, 2008). Increase in soil salinity has been shown to reduce fungal and bac-terial counts (Omar et al, 1994;Pankhurst et al, 2001), as well as, to re-duce microbial diversity and microbial biomass (Ke et al, 2013;Tripathi et al, 2006). Rietz and Haynes (2003) related salinity and sodicity with increased levels of microbial stress and a reduction on the metabolical efficiency of the microbial community.…”

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in soil. The first may affect soil productivity and fertility; the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in agriculture should prevent both types of effects, requiring a holistic and integrated risk assessment. In this article we critically review possible effects of irrigation with treated wastewater, with special emphasis on soil microbiota. The maintenance of a rich and diversified autochthonous soil microbiota and the use of treated wastewater with minimal levels of potential soil contaminants are proposed as sine qua non conditions to achieve a sustainable wastewater reuse for irrigation.

“…Road runoff pollutants have been shown to induce tree mortality (Fan et al 2014), shift the composition of floral and faunal communities (Kaspari et al 2010;Ke et al 2013;Neher et al 2013;Snell-Rood et al 2014), promote establishment of terrestrial and aquatic invasive species (Johnston and Johnston 2004;Crooks et al 2011), and elevate Na concentrations in roadside soils, displacing base cations (Ca, Mg, K) essential to ecosystem function (Norrström and Bergstedt 2001). Flux of displaced cations and Cl into streams has been reported downslope of salted roads (Daley et al 2009;Price and Szymanski 2013;Corsi et al 2015), and Na and Cl concentrations in lakes correlate positively with paved road density (Kelting et al 2012).…”

Road runoff is understood to be a significant stressor in terrestrial and aquatic ecosystems, yet the effects of this stressor are poorly understood at large spatial scales. We developed an efficient method for estimating the spatial impact of road runoff on lands and waters over large geographic areas and then applied our methodology to the 2.4 million ha Adirondack Park in New York State. We used TauDEM hydrologic modeling and a series of ESRI GIS processes to delineate surface flow downslope of paved roads, illustrating the potential movement of pollutants originating from paved roads through the USGS 10 m DEM topography. We then estimated the land and surface water areas, number of water bodies, and total stream length potentially impacted by road runoff from paved roads. We found that as much as 11% of land area, 77% of surface water area, 1/3 of the water bodies, and 52% of stream length in the Adirondack Park may be impacted by road runoff. The high degree of hydrologic association between paved roads and the lands and waters of this region strongly suggests that the environmental impacts of road runoff should be evaluated along with other regional stressors currently being studied. Being able to estimate the spatial impact of road runoff is important for designing monitoring programs that can explicitly monitor this stressor while also providing opportunities to understand the interaction of multiple environmental stressors.

“…Besides the cause of soil itself, e.g., soil type and constituent components, one of main reasons accounting for these changes is that the toxicities of road salt (e.g., Na + and Cl − ) could cause soil health damage and soil structure alteration. For example, when giving de-icing salt solution to soil samples taken from soil layers (0-15 cm, 15-30 cm and 30-45 cm), a trend of increasing electric conductivity values, Na + and Cl − concentrations were found to be apparent, and it was proved that soil salinization would lead to unbalanced microbial community and destroyed micro-ecosystem of bulk soil surrounding plant rhizosphere (Ke et al, 2013). Another potential result of the chloride-salt interactions is the elevated heavy metal mobility in the roadside soil (for example, topsoils across a highway-forest interface northeast of Vienna, Austria), which could be achieved via a number of mechanisms including cation exchange, chloride complex formation and colloid dispersion (Zehetner et al, 2009).…”

With the growing reliance on chloride-based deicers in winter roadway maintenance operations, the concerns over their adverse impacts have been highlighted in recent years, especially the direct stress that applied chemicals bring to the receiving roadside soil, water bodies, aquatic biota, and vegetation through snowmelt runoff, infiltration and wind blow. This work started from synthesizing current knowledge on the negative/toxicological effect of chloride-based snow and ice control products to the natural ecosystem, and then put an emphasis on the examination of typical methods used to assess the toxicity of chloride-based deicers on the water quality and aquatic biota in the laboratory and field tests. The summary focused on the species to test, calculation process, and influential factors in the laboratory test, followed by the field sample collection options, timing of sampling, key variables and bio-assessments in the field test to quantify toxicological effects of chloride-based chemicals. Finally, efforts on current theoretical research and the need for further work (e.g., field monitoring and bio-assessments or bio-monitoring over time, the effective correlation between laboratory toxicity data with field data, and the relationship among key variables and resulting toxicity index) were discussed.
