Abstract:

When industrial wastes get into a natural reservoir, sewage containing trinitrotoluene changes the biological and physical-chemical conditions in the reservoir, inhibits self-purification processes, and makes the reservoir unsuitable as a supply of drinking water. Almost no light has been thrown on the influence of trinitrotoluene on aqueous microorganisms and biochemical self-purification processes in water. Only the study of Ruchoff et al, who studied purification of domestic sewage by physical-chemical and biological methods after trinitrotoluene had been added, contains indications that trinitrotoluene not only inhibits and reduces the rate of self-purification of the reservoirs water but also does not decompose under the influence of biological agents. The authors also indicate that a trinitrotoluene concentration of 5 mgl is fatal for fish.
