The non-methane organic compounds (NMOCs) released from municipal solid waste (MSW) landfills impose significant impact on the environment and human health. It is necessary to investigate the fugitive emission of NMOCs from MSW landfills for helping control NMOC emissions and reduce the environmental impacts. This study was focused on the concentration distribution of NMOCs on the operating and...

Land application of wastewater biosolids is both economical and beneficial to resource recycling. However, this environmentally friendly practice can be at risk due to odor complaints. Volatile organic sulfur compounds (VOSCs) including methanethiol, dimethyl sulfide, and dimethyl disulfide, have been identified as major contributors to biosolids odor. In this study, methanogens were shown to p...

[1] We identify dimethyl disulfide (DMDS) as the major reduced sulfur-containing gas emitted from bushfires in Australia’s Northern Territory. Like dimethyl sulfide (DMS), DMDS is oxidized in the atmosphere to sulfur dioxide (SO2) and methane sulfonic acid (MSA), which are intermediates in the formation of sulfuric acid (H2SO4). The mixing ratios of DMDS and DMS were the highest we have ever de...

A novel method for cleavage of the dithiine ring in 5,12-(dimethyl)-thioqinantrenium bis-chloride 1 "via" reaction with sodium hydrosulfide leads to 1-methyl-3-mercaptoquinoline-4(1H)-thione 2. Further transformation of thiol and thione functions of compound 2 leads to a series of sulfide and disulfide derivatives of quinolinium salts 4 and 6. 1-Methyl-4-chloro-3-benzylthioquinoline chloride 8 ...

The title compound, C(8)H(17)O(2)PS(2), displays a distorted tetra-hedral geometry around the P atom. The P atom is part of a six-membered ring with an isopropyl group in the equatorial position. The mol-ecules are linked by S-H⋯S hydrogen bonds in the crystal packing.
