ntroduction: electrocautery device is one of the most widely used electronic devices in operating rooms despite its advantages in operations, production risks such as the halo of smoke above the operating position. the smoke with hazardous substances,cause to transmitting hiv, hpv and hepatitis and complications such as respiratory distress, nausea and vomiting, eye irritation, headache, and so...

I explore the advantages of tradable emission permits over uniform emission standards when the regulator has incomplete information on firms’ emissions and costs of production and abatement (e.g., air pollution in large cities). Because the regulator only observes each firm’s abatement technology but neither its emissions nor its output, there are cases in which standards can lead to lower emis...

Will economic growth inevitably degrade the environment, throughout development? We present a household-level framework emphasising the trade-off between consumption that causes pollution and pollution-reducing abatement. Our model provides a simple explanation for upward-turning, non-monotonic paths of environmental quality during economic growth. Its innovation yields sufficient conditions th...

In the US, the bulk of CO2 abatement induced by carbon taxes comes from electric power. This paper incorporates technology detail into the electricity sector of a computable general equilibrium model of the US economy to characterize electric power’s technological margins of adjustment to carbon taxes and to elucidate their general equilibrium effects. Compared to the top-down production functi...

There is continuing interest in the trend of costs associated with pollution abatement activities. We specify an environmental production technology to model the joint production of good and bad outputs. The joint production model calculates pollution abatement costs and identifies changes in these costs associated with: (1) technical change, (2) input changes, and (3) changes in bad output pro...

This paper analyzes the output, abatement, and investment decisions made by a monopolistic polluter under environmental liability law. The model applied considers both integrated and end-of-pipe abatement technologies. We find that in the case of fixed technology, in many instances negligence produces more favorable results than strict liability in terms of social welfare. The reason is that ou...

This paper estimates the effect of changing environmental standards on patterns of international investment. The analysis advances the existing literature in three ways. First, we avoid comparing different countries by examining foreign direct investment in the United States and differences in pollution abatement costs among U.S. states. Data on environmental costs in U.S. states are more compa...

risk analysis is an important technique to estimate impacts on the environment for adopting effective measures to avoid risks. this field study was conducted to investigate the risk of brick kiln (bk) smoke on the shoots of acacia arabica. different phenotypic parameters including morphology and growth of shoots and epidermal imprints of the leaves were studied in the vicinity of a brick kiln s...
