Human-induced changes to natural landscapes have been identified as some of the greatest threats to freshwater resources. The change from natural forest cover to agricultural and pastoral activities is rampant especially in the upper Mara River catchment (water tower), as well as along the course of the Mara River. The objective of this study was to determine the effect of land use change on
Fate and Transformation of Graphene Oxide in Estuarine and The possibility of graphene oxide (GO) exposure to the environment has spurred several studies investigating the fate of this nanoparticle (NP). However, there is currently little or no data on the fate of GO in estuarine and marine waters. This study investigated the aggregation, sedimentation, and transformation of GO in saline waters, considering the roles of salinity (050 ), light
Jul 16, 2020 · Manufacturing biochar for energy and high-tech applications requires a specific set of physicochemical parameters based on relationships between initial pyrolytic conditions and properties of starting material, namely biomass. This study compares 20 types of biochar produced from five diverse waste biomasses at two pyrolytic temperatures (400, 700°C), processing times (2, 5 h) and heating
International Center for Himalayan Biodiversity (ICHB 80 USDA Forest Service Proceedings RMRS-P-42CD. 2006. Biodiversity is a global endowment of nature. Conservation of biodiversity includes all species of plants, animals and other organisms, the range of genetic stocks within each species, and ecosystem diversity. Food, many types of medicine and industrial products
National Atmospheric Deposition Program NRSP-3 Acidic atmospheric deposition continues to be a serious environmental concern. Sulfur and nitrogen oxides emitted from industrial and transportation sources, utilities, and metropolitan areas enter the atmosphere and are transformed into acidifying compounds. These pollutants are transported in the atmosphere and are removed, in part, as acidic wet deposition.

The Biofiltration of Indoor Air:Air Flux and Temperature An alternative approach to maintaining indoor air quality may be the biofiltration of air circulated within the space. A biofilter with living botanical matter as the packing medium reduced concentrations of toluene, ethylbenzene, and o-xylene concurrently present at parts per billion (volume) in indoor air. The greatest reduction in concentrations per pass was under the slowest influent air
Methyl bromide can also be conserved to some extent. For example, in a commercial installation in China treating logs, residual gas from one fumigation chamber is transferred to a new fumigation. The concentration is then topped up to specification using new methyl bromide, with a savings of methyl bromide of about 30% use.
