Estimation of stormwater pollutants is a pre-requisite for the protection and improvement of the aquatic environment and for appropriate management options. The usual practice for the stormwater quality prediction is performed through water quality modeling. However, the accuracy of the prediction by the models depends on the proper estimation of model parameters. This paper presents the estima...

The use of strains of Salmonella enterica serovar Typhimurium with different metabolic capacities can indicate the class or classes of compounds present in an environmental sample and enable the diagnosis of the mutagenic activity of these pollutants adsorbed on particulate matter (PM) in the air. In the present study, the sensitivity of Salmonella strains TA98NR, TA98/1,8-DNP₆, YG1021, and YG1...

Air pollution caused by motor vehicles is one of the most serious problems of civilized society. The aim of this paper is to develop a decision support system that can be used by authorities to reduce air pollution from road transport. The essence of this system consists of mathematical sub-models based on the computer program methodology for calculating emissions from road transport, (COPERT I...

Inhalation of airborne chemicals can result in allergic sensitization with episodic pulmonary responses occurring on subsequent exposures. Responses may occur in the upper respiratory tract (rhinitis), the lower respiratory tract (wheeze, bronchospasm) or systemically, for example, a febrile response. The mechanisms underlying these responses are not always clear but include production of reagi...

A multidisciplinary study on a general population exposed to vehicle exhaust was undertaken in Pisa in 1991. Environmental factors such as air pollution and those associated with lifestyle were studied. Meanwhile, biological and medical indicators of health condition were investigated. Chromosomal aberrations, sister chromatid exchanges (SCEs), and micronuclei in lymphocytes were included for t...

Accepted 26 May 1995 Environmental hazards to health have a high public profile, but assessment of the risks that they pose is not easy. What is the morbidity, if any, caused by living near a hazardous waste incinerator? Do oestrogenic alkylphenolic pollutants in drinking water affect reproductive function, and if so, how much? Such questions have important implications for public health policy...

BACKGROUND Ambient particulate matter (PM) has an adverse effect on respiratory morbidity. Desert dust outbreaks contribute to increased PM levels but the toxicity of desert dust mixed with anthropogenic pollutants needs clarification. METHODS We identified 132 days with desert dust episodes and 177 matched days by day of the week, season, temperature and humidity between 2001 and 2006 in Ath...

The World Health Organization is a specialized agency of the United Nations with primary responsibility for international health matters and public health. Through this Organization, which was created in 1948, the health professions of over 190 countries exchange their knowledge and experience with the aim of making possible the attainment by all citizens of the world of a level of health that ...
