Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SO x) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2) Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S 2 O 2) Sulfur dioxide (SO 2) Sulfur trioxide (SO 3)
Emission control areas (ECAs), or sulfur emission control areas (SECAs), are sea areas in which stricter controls were established to minimize airborne emissions from ships as defined by Annex VI [1] of the 1997 MARPOL Protocol. The emissions specifically include SOx, NOx, ODSs and VOCs [2] and the regulations came into effect in May 2005.
Major air pollutants in Sri Lanka are oxides of carbon, oxides of nitrogen, oxides of sulfur, particulates, inorganic compounds, hydrocarbons and the secondary pollutant photochemical smog. These pollutants have negative impact on people's health as they can cause respiratory illnesses, asthma or even death.
Annex 2 - Maximum allowable emissions (emission ceilings) [6] are adopted for 2010 for sulphur, nitrogen oxides (NO x), Volatile Organic Compounds (VOCs) and ammonia (NH 3). The selection of the specific emission levels (in tons/year) were based on the predicted effects of the pollutants and the pollutant control options and costs.
An emission performance standard is a limit that sets thresholds above which a different type of vehicle emissions control technology might be needed. While emission performance standards have been used to dictate limits for conventional pollutants such as oxides of nitrogen and oxides of sulphur (NO x and SO x ), [ 3 ] this regulatory ...
However, the main disadvantage of measuring total national emissions is that it does not take population size into account. China has the largest CO 2 and GHG emissions in the world, but also the second largest population. Some argue that for a fair comparison, emissions should be analyzed in terms of the amount of CO 2 and GHG per capita. [7]
Bunker fuels used within an emission control zone (i.e. North Sea) must have a sulphur content level of less than 0.1% (1000ppm). The IMO has worked on ensuring consistent implementation of the 0.5% sulphur limit in its Marine Environmental Protection Committee (MEPC) and its subcommittee on Pollution Prevention and Response (PPR).
This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions.
