impact of effluent discharge from aquaculture facilities is a growing concern among policy makers. Since 1974, the United States Environmental Protection Agency (EPA) has regulated discharge of pollutants to waters of the United States under authority of the National Pollutant Discharge Elimination System (NPDES) permit. In some states, the NPDES permits have been applied to effluents from aqua...

Controllable CO2 Reduction In article number 2207234, Ruiting Xue, Jun Xie, and co-workers report a silver quantum dot (Ag-QDs) photocatalyst capable of tunneling photocatalytic reaction using surface plasmons. Ag-QDs can be selectively regulated as oxidation or reduction sites drive pollutant under entire solar. This technology is expected to restore ecological environment solve energy crisis.

One alternative measure to minimise the stormwater runoff volume and its pollutants reduce impervious areas is use permeable pavement. However, due weak mechanical performance under heavy-load traffic related fatigue resistance, porous mixtures pavements have restricted applications, i.e., parking lots low-traffic roads. This work aims evaluate resistance of a asphalt mixture produced with high...

Although persistent, bioaccumulative and toxic pollutants (PBTs) are well-studied individually, their distribution and variability on a global scale are largely unknown, particularly in marine fish. Using 2,662 measurements collected from peer-reviewed literature spanning 1969-2012, we examined variability of five classes of PBTs, considering effects of geography, habitat, and trophic level on ...

Air quality and personal pollutant exposure measurement are important for the health and productivity of individuals. Accurate measurement of personal exposure is challenging because of the spatially and temporally heterogeneous distribution of pollutant concentrations. We propose to use low-cost and miniature mobile sensor networks to provide real-time measurement of the environment directly s...

The Greenidge Multi-Pollutant Control Project is being conducted as part of the U.S. Department of Energy’s Power Plant Improvement Initiative to demonstrate an innovative combination of air pollution control technologies that can cost-effectively reduce emissions of SO2, NOx, Hg, acid gases (SO3, HCl, and HF), and particulate matter from smaller coal-fired electric generating units (EGUs). The...

In this study, the effects of hydrogen and hydroxygen additions and oxygen enrichment on the emission characteristics of a gasoline engine (EF7) were investigated and compared with each other. The simulation was launched by GT-Power at different engine speeds with 5 % to 15 % volume fractions for both of oxygen and hydrogen enrichment and 4.5 % to 9 % volume fractions of hydroxygen addition in ...

Abstract: Microplastics can have direct physical effects on organisms in freshwater systems, and are considered as vectors for absorbed environmental pollutants. It is still under discussion if microplastics are relevant pollutant vectors for uptake into aquatic organisms in comparison to further uptake pathways, e.g., via water or sediment particles. We analyzed how the presence of microplasti...
