In summary, the different joint effect models of multicomponent pollutant mixtures (i.e., the toxic unit, additive and mixture toxicity indices) were presented. Using such models to analyze the joint effect of a group of toxic and carcinogenic organic compounds such as polycyclic aromatic hydrocarbons will be presented and evaluated in Sect. 3.2. 

Aromatic amines as a compound class account for many of the known carcinogenic organic chemicals. Perhaps the most widely publicized compounds are benzidine and 3,31-dichlorobenzidine (DCB)(4>5)which until recently were widely used in the manufacture of dyestuffs. Another widely publicized suspected car-cinogenic aromatic amine is 4-methoxy-m-phenylenediamine (MMPDA)(6)which is used as an ingredient in many permanent hair dye formulations. 4,4,-methylenebis(2-chloroaniline) or MBOCA(Z)and 4,4-methylenedianiline (MDA) are widely used as curing agents in polyurethane resins and are said to be carcinogenic. ...

Under the reaction conditions in the NOj, removal process, H2NNO is very short-lived because it is formed in a vibrationally excited state. The highly carcinogenic organic derivatives of nitrosamine R2NNO are more stable and can be isolated in bulk. 

Man is endangered by carcinogenic substances from many sources. The problems of hygienic prophylaxy of malign tumours will not be satisfactory solved until the problems of the environmental pollution by these substances are solved separately. As surface waters are ever more used in water treatment practice, it is in the common interest to protect the hydrosphere against further pollution by carcinogenic organic materials.

If non-carcinogenic organic compounds of several classes are present, the mass concentration in the waste gas must not exceed 150 mg/m with a total mass flow > 3 kg/h. 

In spite of all the efforts taken to purify public water supplies, many consumers are concerned about the quahty of the water that comes out of the taps in their homes, schools, and places of business. Parents of small children are especially worried about chemicals such as lead and carcinogenic organic compounds that are chlorine disinfection by-products. Many have turned to bottled water or home water treatment devices.
