بدلیل بالا بودن درصد رطوبت زباله های شهری، مقدار زیادی شیرابه در فرآیند تبدیل زباله به کمپوست تولید می شود که اگر به شیوه ای مناسب و درست جمع آوری نشود می تواند مشکلات زیست محیطی ایجاد نماید. بعنوان مثال روزانه 500 تن زباله در محل کارخانه کمپوست اصفهان به کود تبدیل می شود که حدود چهل هزار لیتر شیرابه تولید می کند. روش تصفیه ی زمینی برای کشور ایران که دارای منابع محدود آب و البته زمین های بدون ک...
BACKGROUND Environmental air pollution is associated with a higher incidence of respiratory diseases, absenteeism and costs. AIM To model the health related economic benefits associated to a reduction in air pollution and the resulting lower prevalence of respiratory diseases, in a Chilean city. MATERIAL AND METHODS A time series model for year 2006 was elaborated. The dependent variable wa...
Recently, sustainable development and policy on improving the quality of the environment have attracted economists. The use of fossil fuel tax and subsidies to research and development are among the tools that can reduce air pollution by creating economic incentives and relative price adjustments.

Researchers have shown that exposure to noise may increase the risks related to personal health, like nervous frailty, extreme irritability, muscle cramps, stress and anxiety, dizziness, headache and migraine,...
Air pollution reduction policies can simultaneously mitigate CO2 emissions in the industrial sector, but extent of these co-benefits is understudied. We analyse potential for SO2, NOx, particulate matter (PM) and emission major sectors China. construct a firm-level database covering nearly 80,000 observations use scenario simulations to estimate co-benefits. The findings show that substantial c...
