[Preservation of food wastes by a mixture of quinosol and salicyclic acid].

A 90-day experiment has shown that a number of toxic gaseous contaminants are released into the atmosphere as a result of storage of mixed food wastes. The microorganisms dwelling upon decaving food wastes include different microbial species from the environment and food products. A preserving agent consisting of a mixture of quinosole and salicylic acid (1:1) has been used.

Bacterial contamination of confined, sealed space during long-term human occupation.

The long-term presence of human beings in a closed room of small volume is accompanied by the accumulation of a common and hemolytic microflora on their bodies, clothes, in the air, and on the room surfaces. A study was made of the dynamics of the spreading of such microflora in rooms measuring from 5-21 m3 when occupied by 1-3 persons for 5-30 days. With minimal sanitation the skin, after 30-40 days, is covered with several thousands of microbes per cm2, of which the hemolytic staphylococci amount to about 500 cells per cm2.
