Environmental pollution is now a serious problem in many developing countries. One approach to combat the problem is to implement various pollution control policies. However, due to a lack of adequate quantitative models, the economic impacts and effectiveness of many pollution control policies are still unknown. This article uses the computable general-equilibrium (CGE) approach to develop an ...

Control of non-point source (NPS) water pollution remains elusive in the United States (US). Many US water-bodies which have been primarily impacted by NPS pollution have not achieved water quality goals set by Clean Water Act. Technological advances have been made since 1972, yet many water resources fail to meet water quality standards. Common Pool Resources Theory is considered to understand...

This paper describes the usage of linked models for assessment of water quality in a river basin. River water quality model QUAL2K and the Wennerblom (Älvsborg) diffused pollution model were simultaneously applied for water quality and land-based pollution estimations. A software tool was developed to control the data flow between these models and databases. This tool provides automatic formati...

1 This paper analyses the use of economic instruments for control of water pollution in four OECD countries-Denmark, France, Germany and the Netherlands-from 1970-1990. While there is now a vast theoretical literature on the use of economic or market-like instruments, this study is the first empirical investigation of the use of such instruments in a comparative perspective. And although the sp...

Mobile phone based potable water quality assessment device is developed to analyze and study water pollution level at Indus river. Indus river is habitat of endangered Indus river dolphin and water pollution is one of major causes of survivability threats for this specie. We tested device performance at the six locations of Lahore canal. pH of canal water deviates from the normal range of the i...

This paper evaluated the oil spillage risk in the waters near the island of Changxing in Dalian (China) based on the established risk assessment index. Four wind regimes (windless, northerly wind, westerly wind and southerly wind) were selected as weather conditions for the dynamic prediction of oil drift. If an oil spill occurs near the Koumen (a place near the island of Changxing), the foreca...

Objective This paper describes analyses of health seeking behaviors from two surveillance datastreams: Poison Control Center (PCC) calls and Emergency Department (ED) visit records. These analyses were conducted in order to quantify behaviors following the development of symptoms after water contamination exposure and to understand the motivation, decision-making and timing behind healthcare se...

Being in a ship is like being in jail, with the chance of being drowned (Dr. Samuel Johnson) Gastroenteritis is a major health concern aboard cruise ships [1]. Poor sanitation systems and contaminated water and food used to get the blame. As the North American market covers 2/3 of the global cruise volume [2], the U.S. Centers for Disease Control and Prevention (CDC) were particularly intereste...
