Natural discharge

Carbon disulfide [75-15-0] (carbon bisulfide, dithiocarbonic anhydride), CS2, is a toxic, dense liquid of high volatiUty and fiammabiUty. It is an important industrial chemical and its properties are well estabUshed. Low concentrations of carbon disulfide naturally discharge into the atmosphere from certain soils, and carbon disulfide has been detected in mustard oil, volcanic gases, and cmde petroleum. Carbon disulfide is an unintentional by-product of many combustion and high temperature industrial processes where sulfur compounds are present. 

The utilization of geothermal reservoirs involves drilling and extraction of fluid from the reservoir at a rate, which usually far exceeds the natural discharge rate. Often, hot water in... 

Most of the pollutants listed in this chapter find their way into water directly by human or natural discharges (from diffuse or point sources) or indirectly through discharges into soil. It is therefore important to realize that in order to manage or control such direct or indirect pollution, the chemistry of such chemicals must be understood and their physicochemical behavior in soil-water systems predicted. To accomplish these tasks, and to minimize adverse effects on the environment, one needs to have a background in water chemistry, soil mineralogy, soil surface chemistry, and the...
