Biological Effects of Agriculturally Derived Surface Water Pollutants on Aquatic Systems
Environmental manipulations and other human activities are major causes
of stress on natural ecosystems. Of the many sources of surface water
pollutants, agricultural activities have been identified as major
contributors to environmental stress, which affects all ecosystem
components. In water, agricultural contaminants are most noticeable when
they produce immediate, dramatic toxic effects on aquatic life although
more subtle, sublethal...

Human health effects of air pollution
Human health effects of air pollution
Hazardous chemicals escape to the environment by a number of natural
and/or anthropogenic activities and may cause adverse effects on human
health and the environment. Increased combustion of fossil fuels in the
last century is responsible for the progressive change in the
atmospheric composition. Air pollutants, such as carbon monoxide (CO),
sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), ozone (O3),
heavy metals,...
