In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how th...

In New Delhi, the capital city of India, concentrations of regulated air pollutants often exceed the Indian national ambient air quality standards (INAAQS). As the sources of these pollutants differ, it is of utmost priority to understand the most dangerous air pollutant to formulate better control strategies in the city. In this study, regulated air pollutant concentrations in New Delhi during...

Abstract The cross joint is one of the standard connection types for urban water supply pipelines. A pipeline containing joints was taken as research object using NaCl tracer. turbulent mixing characteristics and pollutants at pollutant migration diffusion were studied analysed by numerical analysis experimental measurement. primary purpose to check comprehensive influence six factors pipe diam...

BACKGROUND Given the importance of physical activity to well-being, there is a need to encourage people to be physically active year-round. At the same time, many people are vulnerable to adverse health effects from air pollution, especially on smog alert days. This study was undertaken to determine when air pollution levels tend to be lowest so that the public can modify strenuous outdoor acti...

Abstract In index decomposition analysis, it is common to decompose changes in energy-related CO2 emissions give the effects of five contributing factors. However, extremely challenging derive equivalent air pollutant emission coefficient by fuel type for pollutants. As a result, have typically been decomposed into three factors, i.e. scale, structure, and intensity Using unique facility-level ...

(Received: July 21, 2012; Accepted in Revised Form: July 5, 2013) Abstract: The principal concern of this study is to formulate the sub-pollution indices (sub-LPIs) and evaluate the individual and overall leachate pollutant index (LPI) of pilot scale landfill lysimeter at KUET campus, Bangladesh. To these endeavors, leachate samples from collection chamber of landfill lysimeter were sampling an...

This paper presents a numerical investigation of air pollutant transport from the Los Angeles Basin to Grand Canyon National Park (GCNP) under the stably stratified wintertime, synoptic highpressure conditions that existed during lo-13 February 1987. The Colorado State University Regional Atmospheric Modeling System (CSU-RAMS) is used to develop fields of different atmospheric variables for 54 ...

To evaluate the relative importance of various measures of particulate and gaseous air pollution as predictors of daily mortality in Inchon, South Korea, the association between total daily mortality and air pollution was investigated for a 20-month period (January 1995 through August 1996). Poisson regression was used to regress daily death counts on each air pollutant, controlling for time tr...

Abstract The ground water quality of Okobo Local Government Area was investigated. Sixteen boreholes (BHs) samples were collected from four zones (Okopedi, Ekeya, Ukwong and Okiuso) in Okobo. Standard analytical procedures used to analyze the physicochemical, bacteriological heavy metal parameters results compared Nigerian standard for drinking (NSDWQ). some physicochemical investigated within ...

The highly intercorrelated nature of air pollutants makes it difficult to examine their combined effects on health. As such, epidemiological studies have traditionally focused on single-pollutant models that use regression-based techniques to examine the marginal association between a pollutant and a health outcome. These relatively simple, additive models are useful for discerning the effect o...
