Emission of volatile halogenated organic compounds over various Dead Sea landscapes

Abstract: Volatile halogenated organic compounds (VHOCs), such as methyl halides (CH 3 X; X is Br, Cl and I) and very short-lived halogenated substances (VSLSs; bromoform -CHBr 3 , dibromomethane -CH 2 Br 2 , bromodichloromethane -CHBrCl 2 , trichloroethylene -C 2 HCl 3 , chloroform -CHCl 3 -and dibromochloromethane -CHBr 2 Cl) are well known for their significant influence on ozone concentrations and oxidation capacity of the troposphere and stratosphere and for their key role in aerosol formation. Insufficient charact… Show more

“…Due to phasing out of anthropogenic emissions of chlorofluorocarbons, CH 3 Cl will largely control future levels of stratospheric chlorine. In the last three decades, many natural sources of CH 3 Cl have been discovered, including emissions from tropical plants, mangroves, , wood decay driven by fungi, algae and bacteria in oceans, , plants and salt marshes, , aerated, flooded soil and saline soils from semi-arid areas, senescent leaves, and from thermal destruction of plant matter such as by wild fires. , Anthropogenic CH 3 Cl is released to the atmosphere mainly by combustion of fossil fuels and biomass, with minor emissions from cattle, food production, and humans . Worthy of note, CH 3 Cl emissions from industrial sources, particularly in East Asia, may be much higher than previously assumed .…”

“…Such contaminants can occur in different phases and can pollute different environmental compartments. For instance, the presence of THMs in the atmosphere is of environmental concern as these compounds play an important role on the ozone depletion in the stratosphere (Montzka et al, 1999;Shechner et al, 2019). Also, chlorination of drinking water, wastewater and seawater releases THMs as dissolved disinfection by-products (Chowdhury et al, 2010;Hu et al, 2019;Kim et al, 2015;Padhi et al, 2019), which can contaminate surface water, groundwater and drinking water and poses a serious threat to ecosystem and human health (Bernstein et al, 2020;Komaki et al, 2018).…”

“…Among the different chlorinechloromethane (CH3Cl) is one of the most abundant (around 553 559 pptv according to the 2016 data [1]). Natural sources of chloromethane are manifold, comprising not only the oceans but also plants [2], soils [3,4] and wildfires [5]. The anthropogenic emissions of CH3Cl are mainly related to chemical activities [6], and coal and biomass burning [5], but recently it has been found also in the human breath [7].…”
