Sulfur Emission
Traditionally, measures designed to cut back localized ground-level concentrations of sulphur oxides (SOx) used high-level dispersion. Though these measures reduced localized
health impacts, it's currently accomplished that sulphur compounds travel long distances within the higher
atmosphere and might cause harm far away from the initial supply. So the target should be to cut back total emissions. The extent to that SOx emissions hurt human
health depends totally on ground-level close concentrations, the quantity of individuals exposed, and also the length of exposure. Supply location will have an effect on these parameters; so,
plant siting could be a vital think about any SOx management strategy. The human
health impacts of concern square measure short exposure to sulphur dioxide (SO2) concentrations higher than 1000 micrograms per kilolitre, measured as a 10-minute average. Priority so should run to limiting exposures to peak concentrations. Industrial sources of sulphur oxides ought to have emergency management plans that may be enforced once concentrations reach planned levels. Emergency management plans might embrace actions like victimization various low-sulphur fuels. Historically, ground-level close concentrations of sulphur dioxide were reduced by emitting gases through tall stacks. Since sulphur emissions square measure proportional to the sulphur content of the fuel, a good suggests that of reducing SOx emissions is to burn low-sulphur
fuel like fossil fuel, low-sulphur oil, or low-sulphur coal. Fossil
fuel has the value-added advantage of emitting no particulate once burned.
