Water quality criteria for 2,4,6-trinitrotoluene

Regulatory Toxicology and Pharmacology, 1990
The occurrence of the munitions compound 2,4,6-trinitrotoluene (TNT) in groundwater and surface water surrounding U.S. Army ammunition plants may result in contamination of local drinking water supplies. TNT exerts its primary toxic effect in humans on the hematologic system and liver, but it is also known to cause gastrointestinal effects and ...

Water Quality Criteria for European Freshwater Fish

Chemistry and Ecology, 1988
Abstract 1. For water pollution control purposes, the concentration-addition model for describing the joint effects of mixtures of toxicants on aquatic organisms is appropriate; in this model the contribution of each component in the mixture is expressed as a proportion of the aqueous concentration producing a given response in a given time (e.g.

Irrigation Water Quality Criteria

2018
This chapter focuses on how to evaluate the chemical quality of treated wastewater for use in irrigating plants. The quality of treated municipal wastewater depends to a great extent on the quality of the municipal water supply, nature of the wastes added during use, and the degree of treatment the wastewater has received.

Development of freshwater water-quality criteria for perchlorate

Environmental Toxicology and Chemistry, 2004
Abstract The anion perchlorate (ClO4−) is an oxidizing component commonly used in solid propellants for rockets and missiles; in explosives, flares, fireworks, chemical processes, and automobile air-bag inflators; and for other assorted uses. With recent advances in analytical detection capability, perchlorate has been found in a variety

Biological Parameters for Water Quality Criteria

BioScience, 1968
exists in this approach, since physical and chemical parameters generally are easily defined. However, chemical substances which affect the quality of water are numerous, act in a great range of concentrations, and vary continuously and erratically in concentration.

Water Quality Criteria, Methodology and Management

OCEANS '86, 1986
A new methodology for monitoring and establishing water quality criteria has been devised and employed. It is based on statistical relationships found in the environment and can be used to accept or reject environmental conditions created by manmade influences.

Water quality criteria for marine fisheries

Aquacultural Engineering, 1982
Abstract This paper provides a summary of information on sea water for those engineers who have little experience of water quality but find themselves interested or involved with mariculture. As well as considering the natural environment, changes which occur on removal of sea water to a land-based facility are included.

Research Development on Water Quality Criteria

Applied Mechanics and Materials, 2014
Water quality criteria (WQC) is based on the results of scientific experiments and inferences, which prescribe a limit threshold value to pollutants and other harmful factors in water. The system of water quality criteria study is basically a blank circumstance. It’s urgent to establish water quality criteria to adapt with the characters of China water
