Ambient (outdoor) air pollution is now recognized as an important problem, both nationally and worldwide. Our scientific understanding of the spectrum of health effects of air pollution has increased, and numerous studies are finding important health effects from air pollution at levels once considered safe. Children and infants are among the most susceptible to many of the air pollutants. In a...

Urban air pollution is an important environmental factor that is effecting a large portion of urban dwellers in developing economies. Due to the limitations of dose and impact nature, direct measurement of negative implications of urban air pollution is difficult and WHO has developed indirect methods such as Environmental Burden of Disease. However, in this study to measure the economic costs ...

Chemical flocculants are generally used in drinking water and wastewater treatment due to their efficacy and cost effectiveness. However, the question of their toxicity to human health and environmental pollution has been a major concern. In this article, we review the application of some chemical flocculants utilized in water treatment, and bioflocculants as a potential alternative to these ch...

The direct association between air pollution and morbidity and mortality rates has been proved. This major environmental risk factor has been mainly due to extensive use of fossil fuels. Increasing pollution caused by fossil fuels can threaten human health. This study simulated the effect of green taxes on Iran’s health indicators, i.e., mortality and morbidity. We used a Computable General Equ...

Petroleum hydrocarbons are important energy resources. However, petroleum is also a major pollutant of the environment. Contamination by oil and oil products has caused serious harm, and increasing attention has been paid to the development and implementation of innovative technologies for the removal of these contaminants. Biosurfactants have been extensively used in the remediation of water a...

The impact of pollution and abatement policy within a stochastic endogenous growth model is analyzed. Environmental care is provided by the government and financed through income taxation and government bonds. Due to environmental preferences and partial perception of the individual’s impact on pollution, government debt influences equilibrium growth. Hence, there is an additional growth effect...
