Practically healthy schoolchildren living in the district with a high content of nitrates in drinking water experienced distinct quantitative and functional changes of immune indicators: violation of the ratio of immunoregulatory lymphocyte subpopulations, the high level of spontaneous T-lymphocyte blastogenesis, IgE-hyperglobulinemia. The above changes of the immune system could indicate both body sensitization and its desadaptation under unfavourable conditions.

The authors provide data concerning the content of carcinogenous N-nitrosocompounds in foods manufactured in the Moldavian SSR. Over 100 samples of foods of both vegetable and animal origin have been analyzed. It has been found that foods manufactured in the Moldavian SSR are contaminated with carcinogenous N-nitrosamines but to an insignificant degree. It is concluded that the degree of a relative risk may be regarded as negligible.
