Identification and Odor Generation Pattern of Odor-Causing Compounds in Digested Biosolids During Long-Term Storage

Identification and Odor Generation Pattern of Odor-Causing Compounds in Digested Biosolids During Long-Term StorageThe main objective of this research was to identify the compounds responsible for persistent odors in biosolids during long-term storage using olfactometry measurements and to determine their generation pattern with regard to time of appearance and decline using gas chromatography-mass spectrometry (GC-MS). Headspace analysis was used to quantify shortterm odor-causing organic sulfur compounds and...Author(s)Ritika KackerJohn T. NovakMatthew J.
