SumnLary:The toxic effects of alkali cyanide, complex cyanide-containing heavy metal saltsas of iron, cadmium, copper, nickel and mercury-were invest,igat,ed according to standard methods with the aid of the test organisms Poecilia reticulnta (guppy) as well as t'he green alga Ankistrodesrnus faleatus (B-bis a-mesosaprobic). Since various complex compounds can be photolytically decomposed, also discontinuous light-dark phases were used. As discussed equilibrium calciilation~ have shown. inter alia also the pH-value is iriiportant' in t,he fish organisms used with different react,ions to ions and molecularly dissolred conipoimds. The resnlts are summarized in tables and gmphir representations, the substances investigakd being classified into groups witah "strong" and "high" toxic act'ions.

This chapter covers both aliphatic and aromatic compounds that contain one or more nitrogen atoms in their structures. Only a small number of the nitrogen‐containing compounds that could be considered will be reviewed here based mainly on their uses in industry. Three‐membered rings discussed are ethyleneimine, propyleneimine, and one polyfunctional derivative, triethylenemelamine. Toxicologists, chemists, and biologists have always been interested in ethylenimine and its derivatives because they are reactive, are useful at relatively low doses, and are moderately to highly toxic. Ethylenimines are classic alkylating agents and have toxicological effects similar to nitrogen mustards. Monofunctional derivatives of ethylenimine are less potent in producing the characteristic toxicity of the group than the derivatives that have two or more ethylenimine groups. Finally, polymers of ethylenimine and its derivatives have shown a relatively low order of toxicity. Six simple nitrogen mustards (β‐chloroethylamines) are also covered in this chapter. They are all tertiary amines in which the halogen atom and the amine portion have reactivities similar to the alkyl halides and alkyl amines. They have no significant industrial uses in the United States, but they are used in medicine as “antineoplastic agents” and in treating some nonmalignant diseases. Representative nitrogen‐containing chemicals that have five‐membered rings (pyrrolidine, NMP) and six‐membered rings (piperidine, piperazine, morpholine, and HMTA) are also discussed in this chapter in some detail.

TG protect a water for the purpose of local recreation-inclusive of bathing-the effluent of an upstream clarification plant was chlorinated. Due t o poorly controlled dosing, residual chlorine quantities exceeding the permissible level entered the receiving stream, its biocenosis having been considerably endangered. Detrimental effects on the chemical composition are graphically represented by the measured results for some waters-partly criteria of quality. There is explained that the self-purification capacity of the water decreased by about 30 010 and that the hydrobiological species composition of periphyton was reduced by about 80 O/o. Finally, advice is given concerning the prevention of such damages t o waters.
