Depending on the sensing molecules, the sensor can be designed to react to a range of reactants, from a specific chemical to entire classes of compounds.

At present, no international exchange of hydrochlorofluorocarbon (HCFC) production quotas is permitted under the Protocol.

For the majority of Parties emissions of PFCs have decreased since 1990, while emissions of HFCs and SF6 have increased, HFCs in particular, owing to their use as a replacement for ozone depleting substances controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer.

The Montreal Protocol apos s quot industrial rationalization quot provision allows exchange of production limits of controlled substances individually.

The following main chemicals are restricted arsenic and arsenic compounds, benzine, cadmium, formaldehyde, lead, mercury, nickel, organic tin, PCB, pentachlorophenol, PCT, ozone depleting substances and a wide range of specific chemicals in cosmetics.

Hydrocarbon gas, mixture liquefied, n.o.s. Isobutane

(d) Implementation of measures prescribed by the United Nations Economic Commission for Europe (UNECE) protocols on the control and reduction of volatile organic compounds (VOCs) and nitrogen oxides (NOx).

(g) Implementation of measures prescribed by the UNECE protocols on the control and reduction of VOCs and NOx.

The enzymes remanufactured the hydrocarbons into carbohydrates fungal sugars.

Figures were also given for the indirect GHG carbon monoxide (CO), nitrogen oxides (NOx) and non methane volatile organic compounds (NMVOC), but not for hydrofluorocarbons (HFC), perfluorocarbons (PFC) and sulphurhexafluoride (SF6), emissions of which the team assume were small or zero in 1990.

Oil is a stew of hydrocarbon molecules.

Total emissions of HFCs, PFCs and SF6 (gigagrams of CO2 equivalent)

The law should also provide that a security right may not be created in goods that are physically united with other goods in such a way that their identity is lost in another product or mass.

These regulations establish certifiable standards and control mechanisms on ammonium nitrate based products and compounds, particularly those containing more than 28 per cent by weight of nitrogen.

The Institute had programmes on environmental law, climate change and chemicals and waste management, in particular in collaboration with the United Nations Environment Programme and the Stockholm, Rotterdam and Basel international conventions on chemicals and wastes.

Iran provides chemical analyses of samples taken from cultural heritage artefacts and sites which suggest contact with particulate matter and hydrocarbons, but they are not sufficient to enable the Panel to determine the time of contact or the origin of the particulate matter.

Many Parties mentioned in this regard the substitution of chlorofluorocarbons (CFCs) by HFCs.

PYROPHORIC ORGANOMETALLIC COMPOUND, WATER REACTIVE, N.O.S. .

In accordance with the Montreal Amendment to the Montreal Protocol licensing systems should be systematically applied not only to CFCs but also to imports and exports of other ODS, in particular to CTC, TCA, HCFCs, refrigerant blends containing CFCs and methyl bromide.

There is a chemical that's called perflubron.

VOC volatile organic compound INTRODUCTION

In terms of daily diet, the food intake in off season is sure to be less than that during training, especially that the intake of carbohydrate is controlled while the intake of protein and fiber is increased appropriately.

The International Union of Biochemistry and Molecular Biology (IUBMB), has statutes which specify its mission as to foster and support the growth and advancement of biochemistry and molecular biology as the foundation from which the biomolecular sciences derive their basic ideas and techniques in the service of mankind.

Refrigerated liquefied gases shall be transported in portable tanks conforming to portable tank instruction T75 as described in 4.2.4.2.6 and the portable tank special provisions assigned to each substance in the Dangerous Goods List and described in 4.2.4.3.

Joint CBD UNCCD work programme Pursuant to the decisions by the COPs to the UNCCD and to the CBD, a joint work programme between the two conventions was developed.

Conversely, there is no concentration at which the sulfur compound will smell like vodka.

They take the sediment itself, they extract the oil from it, and from that they can produce compounds which turn out to be very specific to particular microbial groups.

The following guidelines apply to determining the appropriate portable tanks which may be used for transport of particular substances

From 1990 to 1995 the relative shares of the gases did not change significantly, with the exception of HFCs, PFCs and SF6.

(c) Not permitting the export of substances listed in tables I and II of the 1988 Convention and, where possible, substances included in the special surveillance list, to areas of special risk where it is known that they are commonly used to produce illicit drugs, until information is available to establish the legitimate purpose of the chemicals or substances to be imported

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

NITROGLYCERIN MIXTURE, DESENSITIZED, SOLID, N.O.S. with more than 2 but not more than 10 nitroglycerin, by mass .
