In the past decades, shellfish culture has developed in a significant way around the world. However, culture areas are often subject to recurring anthropic pollution. The recrudescent presence of industrial wastes is a source of heavy metals and results in pollutant transfer towards the aquatic environment in estuarine areas. Because of their mode of life, bivalves, including mussels and oyster...

Understanding the characteristics of non-point sources (NPS) pollutions can provide theoretical support for improving water quality. Siheshui watershed located in south China was selected to explore the characteristics of NPS pollutions in rainfall-runoff process. In this small agricultural watershed, five flood events and one non-flood event were monitored, and the water quantity and quality c...

This study investigates the relationships among pollutant emissions, energy consumption and economic development in China during the period 1982-2007 by using one-step GMM-system model under multivariable panel VAR framework, controlling for capital stock and labor force. Regarding the data for all 28 provinces as a whole, we find that there is a unidirectional positive relationship running fro...

One of the main concerns of all industries such as mine industries is to increase their profit and keep their customers through improving quality level of their products; but increasing the quality of products usually releases air pollutants. Nowadays the management of air pollutant emissions with harmful environmental and health effects is one of the most pressing problems. In this paper, auth...

Though runoff from manure spread fields is recognized as an important mode of nonpoint-source pollution, there are no models that mechanistically describe transport from a field-spread manure-type source. A mechanistic, physically based model for pollutant release from a surface source, such as field-spread manure, was hypothesized, laboratory tested, and field-applied. The primary objective of...

BACKGROUND Children with asthma in inner-city communities may be particularly vulnerable to adverse effects of air pollution because of their airways disease and exposure to relatively high levels of motor vehicle emissions. OBJECTIVE To investigate the association between fluctuations in outdoor air pollution and asthma morbidity among inner-city children with asthma. METHODS We analyzed d...

Ambient air quality and traffic density measurements were conducted during January to December 2001 at four air monitoring sites in Bangkok Metropolitan Region (BMR). The ambient air pollutants included carbon monoxide (CO), particulate matter (PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3) and benzene. The diurnal variations of air pollutant levels were generally identical to ...
