Global emissions of hydrogen chloride and chloromethane from coal combustion, incineration and industrial activities: Reactive Chlorine Emissions Inventory
Much if not all of the chlorine present in fossil fuels is released into the atmosphere as hydrogen chloride (HC1) and chloromethane (CH3C1, methyl chloride). The chlorine content of oilbased fuels is so low that these sources can be neglected, but coal combustion provides ignificant releases. On the basis of national statistics for the quantity and quality of coal burned during 1990 in power a...
متن کاملReactive airway disease after chlorine gas exposure.
We read with great interest in the September 1991 issue of Chest the case report by Moore and Sherman.’ Chlorine gas exposure has multiple toxic effects on the respiratory system, including immediate airflow obstruction, ARDS, and death. The long-term effects can include abnormalities in gas transfer, restriction, and airflow obstruction. These generally resolve with time to a variable degree. ...
متن کاملMeasurement and Deduction of Emissions of Short-lived Atmospheric Organo-chlorine Compounds
Atmospheric studies of halogenated organics have centered on long lived halocarbons due to their effect on stratospheric ozone. Now that controls have been put in place to curb emissions of longer lived halocarbons through the Montreal Protocol, and speculation about the safety of many short-lived chlorinated organic molecules has been raised, there has been more consideration given to the effo...
متن کاملImpact of chlorine emissions from sea-salt aerosol on coastal urban ozone.
The ability of photochemical models to predict observed coastal chlorine levels and their corresponding effect on ozone formation is explored. Current sea-spray generation functions, a comprehensive gas-phase chlorine chemistry mechanism, and several heterogeneous/multiphase chemical reactions considered key processes leading to reactive chlorine formation are added to an airshed model of the S...
متن کاملThe impact of anthropogenic chlorine emissions, stratospheric ozone change and chemical feedbacks on stratospheric water
Mixing ratios of water (H2O) in the stratosphere appear to increase due to increased input of H2O and methane from the troposphere and due to intensified oxidation of CH4 in the stratosphere, but many of the underlying mechanisms are not yet understood. Here we identify and quantify three chemical mechanisms which must have led to more efficient oxidation of CH4 in the stratosphere over the pas...
