Environmental Science & Technology, 1991
Over the past decade, public and governmental awareness of environmental problems has grown steadily, with an accompanying increase in the regulation of point sources of pollution. As a result, great strides have been made in cleaning polluted rivers and decreasing air pollution near factories.

The US Environmental Protection Agency has criteria inorganic outdoor air pollutants as follows: carbon monoxide (CO), nitrogen dioxide, sulfur dioxide, ozone, lead, and suspended particulate matter, which have widely variable chemical compositions. Most studies have focused on neurological and cardiac effects related to acute high-level CO exposures ...

Abstract Ecosystems around the globe are increasingly being inundated with a cocktail of chemical pollutants. From antidepressant drugs found in the tissues of fish from the Niagara River to persistent organic pollutants detected in polar bears from Arctic ecosystems, pollutants are capable of affecting the development, physiology ...

Chemical pollution and biodiversity
2023Cette communication orale rend compte des effets des pollutions sur la biodiversité. Elle évoque les conséquences en termes de mortalité comme autant d'indices et de traces de la catastrophe chronique, mais elle souligne également l'intérêt d'utiliser la faune et la flore comme indicateurs des atteintes environnementales et sanitaires.

Microorganisms and Chemical Pollution
BioScience, 1973Microorganisms are unquestionably important in chemical pollution and pollution abatement. They are environmental decontaminating agents par excellence, ridding waters and soils of many natural and synthetic compounds which are not desired at that time or place or concentration. They sometimes are significant, too, because they may synthesize hazardous

Pollution and the Chemical Industry
1998Large-scale and widespread industrial production opened a new phase in the relationship between nature and society.1 Wherever industries appeared, communities were confronted with the problems of their emissions. This had an impact on every industrialising country.

As on previous occasions, contributions to the symposium on the subject of “Chemical Pollution of Sludge” concentrated on the heavy metals problem. The papers dealt with analytical studies conducted within the programme established by Working Party 2 (WP 2) of Concerted Action 68 bis, by members of WP 2 and a number of other laboratories from the ...
