CHEMICAL POLLUTION OF THE ENVIRONMENT WATER SOURCES AND HEALTH

Environmental Engineering and Management Journal, 2004
The progress of civilization as a whole (urbanization, demographical explosion and massive concentration of humans in towns and cities, vertiginous industrialization, the intense development of the motorized traffic, the chemical substances used in agriculture and even in the domestic economy etc.) has profoundly altered the living environment of human

Chemical Indicators of Surface Water Pollution

2006
High quality surface water is critical for maintaining healthy ecosystems and ensuring safe drinking water, yet is often compromised by point and non-point contamination sources. Failed septic systems, an example of non-point source pollution, may generate pools of untreated or minimally treated wastewater that can runoff into nearby streams. There are

Effects of water pollutants and other chemicals on fish acetylcholinesterase (in vitro)

Environmental Research, 1980
Acetylcholinesterase (AChE) preparations from the muscle of the fathead minnow (Pimephales promelas Rafinesque) were treated (in vitro) with 74 chemicals of various classes, many of which are environmental contaminants, to determine their effect upon enzyme activity.

Water, Endangered Ecosystem: Assessment of Chemical Pollution

Journal of Environmental Engineering, 1992
The pervasive nature of water and its accessibility to mankind leave it open to a variety of civilization-induced changes ranging from diversion of water flows to heavy-metals pollution. The abuses of the last 100 years have led to problems with water quality and quantity.
