Nature and frequency of the existence of mold fungi in garbage cans for bio-waste and the airborne spore pollution resulting from it

In organic waste, numerous mold fungi and other microorganisms develop some times within a few hours only which decompose the organic material already in the collecting containers generating heat and odor. With regard to the e mission of mold fungus spores out of garbage cans for bio-waste and the pot ential environmental-hygienic danger connected with it, considerable worrie s have been expressed recently. A wide spectrum of mold fungi can be found in bio-waste in strongly varying concentrations. No noticeable difference c ould be ascertained between the settlement structure areas and the cities r espectively as to the fungus concentration in the bio-waste substrate. A. f umigatus and A. niger can be recommended as leading spores far the behavior of the total concentration of fungi in the bio-waste due to their frequenc y of detection and their seasonal dynamism. The intensity of the air spore pollution through emission of mold fungus spores correlates closely with th e climatic conditions, such as variations of temperature, relative humidity and solar radiation. The airborne release of mold fungus spores out of gar bage cans for bio-waste and the formation of a respective exposure connecte d with it is judged as harmless for healthy persons. Risk patients anti persons having a weakened immune system or assumed to ha ve such a one due to on existent basic illness and/or other reasons should avoid any handling of bio-waste as well as any other waste if possible.
