In this paper, original thermosensitive copolymers bearing phosphonic acid groups, namely the poly(N-n-propylacrylamide-stat-2-(methacryloyloxy)methylphosphonic acid) (P(NnPAAm-stat-hMAPC1)) were synthesized, and their sorption properties for three divalent cations (Ni(2+), Ca(2+), Cd(2+)) and one trivalent cation (Al(3+)) have been investigated. The sorption experiments were performed with inc...
OBJECTIVES Air pollution contributes to mortality and morbidity. We estimated the impact of outdoor air pollution on public health in Seoul metropolitan area, Korea. Attributable cases of morbidity and mortality were estimated. METHODS Epidemiology-based exposure-response functions for a 10 μg/m3 increase in particulate matter (PM2.5 and PM10) were used to quantify the effects of air pollutio...
Abrupt environmental pollution accidents cause considerable damage worldwide to the ecological environment, human health, and property. The concept of acceptable risk aims to answer whether or not a given environmental pollution risk exceeds a societally determined criterion. This paper presents a case study on acceptable environmental pollution risk conducted through a questionnaire survey car...
Using China’s provincial economic and pollution data from 1992 to 2008, we employ data envelope analysis (DEA) and econometric analyses to explicitly estimate technical efficiency and examine the role of technical efficiency, pollution control instruments (pollution levy and pollution quantity control), and prices of production inputs on pollution intensity. We find that an increase of labor wa...
The impact of urban air pollution on the environments and human health has drawn increasing concerns from researchers, policymakers and citizens. To reduce the negative health impact, it is of great importance to measure the air pollution at high spatial resolution in a timely manner. Traditionally, air pollution is measured using dedicated instruments at fixed monitoring stations, which are pl...
In the past 30 years, China’s economy has experienced rapid development, which led to a vast increase in energy consumption and serious environmental pollution. Among the different types of pollution, heavy metal pollution has become one of the major environmental issues in China. A number of studies show that high level of heavy metal exposure is a frequent cause of permanent intellectual and ...
