Understanding the differences in the effects of environmental contamination on children and adults is an important part of environmental policymaking; however, unless environmental health policies reflect the differences between adults and children, this knowledge will have little practical effect. The authors of this article consider how the unique vulnerabilities of children challenge environ...
Carabid beetles (Coleoptera, Carabidae) are one of the most studied soil groups in relation to heavy metal (HM) accumulation and use for bioindication of environmental pollution. Accumulation of Zn and Cu in carabid beetles was species-, sex- and trophic group-specific. No differences were found in HM contents between omnivorous and carnivorous species. The use of carabid beetles as indicators ...
This paper explores both theoretically and empirically whether or not the willingness to pay (WTP) for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions, which are not necessary for an environmental Kuznets curve relationship between pollution and income. Our empiric...
The literature argues that income growth leads to increased demand for environmental quality and thus reduction in pollution. Using a utility theoretic model, we hypothesize that the income±pollution relationship should depend on the level of disamenity of the pollutant. We proxy for disamenity using the toxicity of releases. For counties in the United States, the functional relationship betwee...
In this paper we consider the dynamic behavior of a firm that is subject to environmental regulation. It is assumed that, in order to prevent firms from polluting the environment excessively, the government imposes an emissions tax. We determine how an emissions tax influences the firm's decisions concerning investments and abatement efforts. In the model we incorporate the realistic property t...
BACKGROUND Developing countries have limited air quality management systems due to inadequate legislation and lack of political will, among other challenges. Maintaining a balance between economic development and sustainable environment is a challenge, hence investments in pollution prevention technologies get sidelined in favor of short-term benefits from increased production and job creation....
background: although lebanon is a highly polluted country, so far no study has specifically been designed to assess the association between outdoor air pollution and chronic bronchitis in this country. objective: to assess the association between exposure to outdoor air pollution and chronic bronchitis in lebanon. methods: a pilot case-control study was conducted in two tertiary care hospitals....
OBJECTIVE To evaluate the environmental and technical efficiencies of China's industrial sectors and provide appropriate advice for policy makers in the context of rapid economic growth and concurrent serious environmental damages caused by industrial pollutants. METHODS A data of envelopment analysis (DEA) framework crediting both reduction of pollution outputs and expansion of good outputs ...
