More stringent control of sulphur emissions can be exercised in special sulphur oxide emission control areas.

The Baltic Sea is designated as a sulphur oxide emission control area in the Protocol.

352. Annex VI prohibits deliberate emissions of ozone depleting substances, which include halons and chlorofluorocarbons (CFCs), and sets limits on the emissions of sulphur oxide and nitrogen oxide from ship exhausts.

3 The anthropogenically produced greenhouse gases include carbon dioxide (CO2) methane (CH4) nitrous oxide (N2O) hydrofluorocarbons (HFCs) perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

At a minimum, information should be provided on the following greenhouse gases carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs), and sulphur hexafluoride (SF6).

MEPC also adopted amendments to the regulations for the prevention of air pollution from ships in annex VI, which include making the North Sea a sulphur oxide emission control area, and to the nitrogen oxide technical code (resolution MEPC.132(53)). The amendments will enter into force in November 2006.

Sulphur hexafluoride (SF6)

Ethylene oxide

Ethylene oxide

Ethylene oxide and chlorotetrafluoroethane mixture, with not more than 8.8 ethylene oxide

Ethylene oxide and pentafluoroethane mixture, with not more than 7.9 ethylene oxide

Ethylene oxide and tetrafluoroethane mixture, with not more than 5.6 ethylene oxide

In the 1980s and 1990s, widespread concern about acid rain pollution in North America and Europe led to extensive research and assessment efforts that greatly enhanced understanding of long distance transport of sulphur and nitrogen oxide pollution.

For Sri Lanka, the greater concern is on account of the entry into the lungs of human beings of toxic gases and particulate matter, including carbon monoxide, hydrocarbons, nitrous oxide, sulphur dioxide and airborne carbon and lead.

(i) Reduce emissions of nitrous oxide.

Propylene Sulphur dioxide Trifluorochloroethylene, inhibited (Refrigerant gas R 1113)

These rockets use experimental motors like nitrous oxide.

By way of tax incentives normal diesel fuel (sulphur 0.2 per cent) has been totally replaced by diesel with a low sulphur content (less than 0.05 per cent).

Inventory data submitted by 18 reporting Parties for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), emissions from international bunkers, other GHGs, ozone precursors and sulphur dioxide (SO2) for 1990 and 1995 appear in tables A.1 to A.12 in the addendum (document FCCC SBI 1997 19 Add.1).

emissions to air TRI toxics, sulphur dioxides, nitrogen oxides, CO2 etc.

I've got a whole deskful of work. There's the sulphur deal.

Solid fossil fuels are most frequently used for heating, which contain 2.5 4 per cent sulphur and which produce large quantities of sulphur dioxide and ash (20 30 per cent).

It sets the global cap on the sulphur content of any fuel oil on board ships and provides for the future monitoring of the worldwide average sulphur content of fuel.

Nitrous oxide will remain a small component of Icelandic emissions.

Emissions of nitrous oxide (N2O) totalled 108 Gg, carbon monoxide (CO) 6.7 Gg, nitrous oxide (NOx) 2,740 Gg and non methane volatile organic compounds (NMVOC) 25,400 Gg.

(xi) Limit and or reduce emissions of hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride

Sixty four Parties (52 per cent) reported emission estimates of sulphur dioxide (SO2).

Limitation and reduction of emissions of hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. Annex B

(b) Aluminium oxide slag and micro particles from orbital solid rocket motor firings

A number of initiatives have been taken to reduce sulphur dioxide emissions and nitrogen oxygen emissions.

Most Parties reported emissions of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6), although not uniformly.

And they were the first people to describe this new chemical transmitter, nitric oxide.

Emissions of methane could be slightly reduced, while those of nitrous oxide could increase.

And the reason for this, it turned out, after two or three years' work, was that in the skin we have huge stores not of nitric oxide, because nitric oxide is a gas, and it's released and in a few seconds it's away, but it can be turned into these forms of nitric oxide nitrate, NO3 nitrite, NO2 nitrosothiols.

Sulphur dioxide concentration above the ceiling provokes respiratory problems in the population, particularly chronic patients and children.

Large quantities of sulphur dioxide are emitted in the air because lubricants are in use for heating.

Eighteen Parties (15 per cent) provided estimates of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and or sulphur hexafluoride (SF6).
