A class of volatile organic chemicals has been identified as the first group of contaminants for possible regulation (see Chapters 1.13, 2.11, and 2.13). Although the nation is not at a critical state with respect to water quality and drinking water, the infrastructure needed to treat,...
so DO provides useful information for interpreting changes in flora and fauna. DO is a state variable balanced between photosynthesis, respiration, chemicaloxidation, and transport of oxygen from the air and between water masses. In thesurface water, DO is often used a proxy measure of primary pr...
both the introduction of oxygen vacancies via N doping and the subsequent Au deposition are able to prolong the exciton lifetime, leading to an increase to 2.56 ns from the 1.12 ns of pristine P25. It is widely agreed that the separation...
Inexpensive, highly effective methods for the in-situ reduction of hexavalent chromium to the non-toxic trivalent oxidation state in soil and groundwater containing hexavalent chromium are provided, which may reduce hexavalent chromium concentration in soil to as low as 5 mg/L. The methods involve ...
Groundwater makes up 98 percent of the usable water on Earth [source: Groundwater Foundation]. Not to be confused with surface water that we see in lakes, rivers and oceans, groundwater comes from rain, snow, sleet and hail that soaks into the ground. It fills the spaces between roc...
To establish effective water quality monitoring strategies in estuaries, it is imperative to identify and understand the main drivers for the variation of water quality parameters. The tidal effect is an important factor of the daily and fortnightly vari
Water is widely used as a raw material, ingredient, and solvent in the processing, formulation, and manufacture of pharmaceutical products, active pharmaceutical ingredients (APIs) and intermediates, compendial articles, and analytical reagents. This general information chapter provides additional information...
State-of-the-art instrumentation was used to measure the tidal energy resource and turbine wake flow velocities, turbine power extraction, test platform loadings and platform motion induced by sea state. The MEHT was able to generate power from tidal currents over a wide range of conditions, ...
