this paper investigates the impacts of economic and financial developments on environmental pollution for 6 opec countries using panel cointegration and panel long-run estimator (dols) over the period 1980–2008.  the results shows that both economic and financial development have significant effect on the environmental quality in selected opec economies. the findings not support the existence o...

GreenHouse Gasses’ (GHG) emission control is the greatest environmental challenge facing the world. The energy sector accounts for the highest percentage of environmental pollution. Emissions from internal combustion power generators are high and these emissions are responsible for the fast depletion of the ozone layer. Though there are other measures put in place to control the emission from p...

Over the past 30 years, the economy of China has sustained rapid growth. However, the extensive development pattern severely deteriorates the ecological environment, which has been recognized as adverse effects on citizens’ physical and mental health.

The U.S. health care sector is highly interconnected with industrial activities that emit much of the nation's pollution to air, water, and soils. We estimate emissions directly and indirectly attributable to the health care sector, and potential harmful effects on public health. Negative environmental and public health outcomes were estimated through economic input-output life cycle assessment...

The air pollutions from combustion flue gas and industrial gases became worse and cause the environmental problem. It is difficult for the conventional methods such as selective catalytic reduction method and lime-gypsum method to treat exhaust gases energy efficiently and inexpensively. Its energy efficiency and its initial and running costs are still in negative situation for the backward nat...
