'The decomposition of these food derived waste sludges is expected to produce volatile fatty acids (proprionic, butyric, isovaleric, isobutyric, etc.), alcohols, aldehydes and mercaptans (methyl, ethyl, and propyl)."
"The concentration of ammonia in the waste material cannot be translated directly to an air concentration for evaluation. However, its presence in the waste material likely plays a significant role in the odors and health complaints generated in this case. In addition to the ammonia present in the gasses generated, each of these compounds can be very strong odorants."
"Low levels of these compounds in the air can certainly result in objectionable odors. In sensitive individuals these exposures may trigger physical irritation effects and nausea. These irritation symptoms are particularly noted when the exposures include low to moderate amounts of ammonia. The most common symptoms attributed to exposure to these compounds are irritation of the eyes, nose, and throat, headaches, and nausea. A number of consistent irritation effects were reported by some of the residents in the area during periods of strongest odors. "
"Elderly people, children, and people with lung diseases, such as asthma or emphysema, may be especially sensitive to these effects."
[Many of the chemicals emitted by food sludge are also emitted by sewage sludge, including aldehydes; methyl, ethyl and propyl mercaptans; and ammonia.]
