[The effect of the multiyear agricultural use of animal husbandry wastes on the infectious morbidity of the local population]. / Vliianie mnogoletnogo sel'skokhoziaistvennogo ispol'zovaniia otkhodov zhivotnovodstva na infektsionnuiu zabolevaemost' mestnogo naseleniia.

The report presents results of study of relationship between the longterm practice of utilization of waste matter from livestock industry (solid, liquid portions of manure, redundant active silt) in the crop-growing of the steppe, forest-steppe zones as well as of those of woodlands in Ukraine, on the incidence of acute infective diseases of the intestine in the community. The soil of farm lands was found out to be affected by an extensive bacterial contamination due to the above wastes being utilized on a wide scale. The degrees of risk of acute intestinal infection morbility in population areas located in those zones having utilization fields, are significantly higher than beyond their bounderies. Significant direct relationship between the size of the utilization fields and the incidence of acute intestinal infection in the community was established.

[Hygienic study of an activated fibrous charcoal material as a sorbing filtering element for drinking water afterpurification]. / Gigienicheskoe izuchenie aktivirovannogo uglerodnogo voloknistogo materiala v sostave sorbiruiushchego fil'truiushchego élementa dlia doochistki pit'evoi vody.

The results of complex toxicological and hygienic study showed that the quality of pipe water filtered through the activated carbonic fibrous material (ACFM) "Dnepr-F" forming a part of absorptive filtering element improved markedly. The content of organic substances decreased drastically as well as that of nitrates and iron. Microbiological indices did not suffer appreciable changes and were within permissible limits. The water filtered through the absorptive element with ACFM had no adverse influence on the organisms of warm-blooded animals. Proceeding from foregoing one can conclude that the "Dnepr-F" may be recommended as a part of absorptive filtering element for the final refinement of drinking water.
