BACKGROUND Previous epidemiologic studies have considered the effects of individual air pollutants on birth outcomes, whereas a multiple-pollutant approach is more relevant to public health policy. OBJECTIVES The present study compared the observed effect sizes of prenatal fine particulate matter (PM2.5) and polycyclic aromatic hydrocarbons (PAH) (a component of PM2.5) exposures on birth outc...

Abstract Shahdadroud River is one of the most important rivers in Kerman province that during previous years has been threatened by drought and anthropogenic pollution. This river supplies some parts of drinking water of Kerman city and some vicinity villages. The main objective of the present study is consideration of pollution situation of the river; for this purpose, limnological and biolo...

We present a hybrid numerical method for computing the propagation of a diffusing passive pollutant in shallow water. The flow is modeled by the SaintVenant system of shallow water equations and the pollutant propagation is described by a convection-diffusion equation. In this paper, we extend the hybrid finite-volume-particle (FVP) method, which was originally introduced in [CK04, CKP06] for t...

Purpose: The reason for this study is because of observed difference in environmental condition Lagos metropolis. change witnessed arising from air, water and noise pollution mostly increasing vehicle emissions the State. This has been conducted to analyze effects on pedestrians. Specific objectives are determine air quality city at most populate headquarters each 20 Local Government Areas Stat...

Concentrations of heavy metals in irrigation water and soil were examined to determine the level contamination a particular channel Gazipur, Bangladesh. In this conduit, effluent from households, industries, municipalities was combined with water. The study carried out order estimate pollutant loads along wastewater conceptualize seasonal changes composite wastewaters. A total six nine contamin...

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...

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...

BACKGROUND Prenatal exposure to endocrine-disrupting chemicals (EDCs) may induce weight gain and obesity in children, but the obesogenic effects of mixtures have not been studied. OBJECTIVE We evaluated the associations between pre- and perinatal biomarker concentrations of 27 EDCs and child weight status at 7 years of age. METHODS In pregnant women enrolled in a Spanish birth cohort study ...
