Aiming at the maladies of high labor intensity, low efficiency ice and snow removal, environmental pollution in traditional ice-deicing snow-melting methods, we successfully developed a material that can effectively reduce adhesive force between with pavement, aimed characteristics road de-icing melting. According to evaluation index method performance, determined ratio three components film-fo...

BACKGROUND Epidemiological studies have demonstrated associations between short-term exposure to PM2.5 and hospital admissions. The chemical composition of particles varies across locations and time periods. Identifying the most harmful constituents and sources is an important health and regulatory concern. OBJECTIVES We examined pollutant sources for associations with risk of hospital admiss...

Thirty water wells were sampled in 2018 to understand the geochemistry and age of groundwater Williston Basin assess potential effects shale-oil production from Three Forks-Bakken petroleum system (TBPS) on quality. Two geochemical groups are identified using hierarchical cluster analysis. Group 1 represents younger (median 4He = 21.49 × 10?8 cm3 STP/g), less chemically evolved water. 2 older 1...

The environmental implications of soil salinity caused by accumulation of de-icing salt and leaching in soils of northeastern Spain were examined. For this purpose, the concentrations of ions associated with diagnosing and managing this problem were evaluated from several measurements performed over one year along a road. This analysis demonstrated a higher concentration of soluble Na⁺ in the s...

Freshwater salinization is an emerging environmental filter in urban aquatic ecosystems that receive chloride road salt runoff from vast expanses of impervious surface cover. Our study was designed to evaluate the effects of chloride contamination on urban stormwater pond food webs through changes in zooplankton community composition as well as density and biomass of primary producers and consu...
