In this paper, assumptions regarding future land use as a key uncertainty is considered and its impact on risk analysis for contaminated sites is assessed. Risks are assessed for two land use scenarios (current-use industrial and future-use residential) using probabilistic models that incorporate uncertainty and variability in the exposure parameters. Residual risks are calculated for both indu...
The EPA Supersites Research Program needs consistency of metadata and data structures to facilitate information sharing among investigators, analysts, and ultimately secondary data users. Under the auspices of NARSTO a successful mechanism was created to develop and implement reporting standards. The development effort included working closely with Supersites data coordinators, investigators, a...
Observable actions in response to decreases in environmental quality are identified for passive users, those who will never use a damaged resource directly. The welfare implication of changes in the probability and value of time devoted to viewing news of the Valdez oil spill is estimated using a household production approach and assuming weak substitutability between news consumption and envir...
Plant identification is the building brick of plant research and development, and is very important for environmental protection and exploration. Usually, the leaves can be easily obtained from a plant and have sufficient visible characteristics for differentiating between their respective plant species. Plant identification is a huge problem that has escaped into neglect for years. Without vis...
The Science and ‘art’ of wastewater engineering stretches only slightly beyond one hundred years. Within this period, the applied technology has certainly made significant strides in promoting disease control and environmental protection. Fixed-film treatment unquestionably plays an important role in this history, particularly since it represented the original biological mechanism. Beginning wi...
This summary is intended to accompany the Up-and-Down Procedure (UDP) test guideline and the AOT425StatPgm program and assist the user in interpreting its output. The conclusions in this summary are derived from applying the test procedure to many repetitions of test simulations. More extensive treatment of the simulations can be found in the report “Simulation Results for the AOT425StatPgm Pro...
In order to safeguard the future of Chinese automobile industry, and maintain and strengthen its acceptance in Chinese community, it should be made a commitment to sustainability. The approaches to sustainability in Chinese automobile industry should comprise three aspects: nature conservation, production-related environmental protection and “5R” implementation which is considered as sustainabl...
FDI not only affects the host country's economic growth, but also affects the environment. Under the background of reality that in pursuit of green development, we need to take the comprehensive consideration of FDI performance from economic growth and environmental pollution. Considering the economic and environmental factors, we estimated 280 cities' green development efficiency in China from...
