Carbon dioxide can be used in its liquid (near critical) or supercritical fluid state as a replacement for conventional cleaning solvents, reducing the pollution associated with the operations that would otherwise require significant amounts of volatile organic compounds, ozone depleting substances, or hazardous air pollutants. The results of several near critical/supercritical parts cleaning a...

Toxic Chemicals These substances are hazardous to human health and the environment. In 2004 North American industrial facilities generated over 5 million tonnes of toxic chemicals as production-related pollutants and waste (see box). Despite this large amount, data for comparable industries and chemicals in Canada and the United States reveal encouraging trends. Over the period 1998–2004, total...

The top of the world may look pristine, but the Arctic environment and its inhabitants contain surprisingly high levels of heavy metals, persistent organic pollutants such as pesticides, and nuclear radiation. Although the Arctic has few significant pollution sources, the contaminants are swept northward on ocean currents and winds from industrial regions. Once contaminants arrive, low temperat...

Atmospheric corrosion is a significant problem given destruction of various materials, especially metals. The corrosion investigation in the industrial city environment was carried out during one year exposure. Corrosion potential was determined using the potentiometric method. The highest effect of corrosion processes was observed during the winter season due to increased air pollution. Corros...

pollution of urban soils dramatically reduces life and environmental quality. the most commonpollutants are heavymetals and organic contaminants like polycyclic aromatic hydrocarbons and polychlorinatedbiphenyl. main source of these pollutants is fossil fuels which are pervasive in urban and/or industrializedareas. identifying type and intensity of the pollution is essential to prepare an effec...

Environmental pollution poses a great health hazard to human beings, animals and plants. Pollution has also adverse effects on the land, water and its living and nonliving components. Industrial effluents, containing organic and inorganic compounds have strong influence on the development of growth of crop plants. When the concentration of the pollutants in the effluents are low, the agricultur...

This paper describes the results of an industrial pollution prevention pilot project in Nebraska. The goal of the project is to demonstrate that through proper management and operating practices, that industrial pollution can effectively be reduced significantly. The net effect of this pollution prevention program is to improve the economic worth of the industry by lowering expenditures on poll...

This paper examines and quantifies the complex linkages between industrial activity, environmental regulations and air pollution in China. We utilize a little used dataset of Chinese industry specific emissions for a variety of pollutants between 1996 and 2003. Our analysis allows us to investigate the role played by different determinants of emissions intensity. We find pollution intensity to ...

In view of the extensive use of foraminifers for the pollution monitoring especially their unmatched utility in deciphering the temporal variation in the type and concentration of pollutants at a given location, the literature dealing with the application of foraminifers for pollution studies has been reviewed. The pollution monitoring through foraminifers started with attribution of peculiar f...
