While being toxic to marine life, polycyclic aromatic hydrocarbons (PAHs), the components in crude oil, are very difficult to clean up, and last for years in the sediment and marine environment.

For example, they may be synthetic organochlorides such as plastics and pesticides, or naturally occurring organic chemicals such as polyaromatic hydrocarbons (PAHs) and some fractions of crude oil and coal.

These are the same bonds that hold hydrocarbons together.

The enzymes remanufactured the hydrocarbons into carbohydrates fungal sugars.

Energy minerals include hydrocarbons such as petroleum and coal, and radioactive minerals.

The presence of an amine group strongly increases the reactivity of the aromatic ring, due to an electron donating effect.

In 1974, the House of Chanel launched Cristalle eau de toilette, which was designed when Coco Chanel was alive.

Bacteria capable of digesting the hydrocarbons in petroleum are often used to clean up oil spills.

The economy remained weak, however, with dependence on a few commodities, including vanilla.

The reservoir must also be permeable so that the hydrocarbons will flow to surface during production.

List known and reasonably anticipated hazardous decomposition products produced as a result of use, storage and heating. Hazardous combustion products should be included in Section 5 Fire fighting measures of the SDS.

It consists of a complex mixture of hydrocarbons of various molecular weights, plus other organic compounds.

Emissions of perfluorized carbons (PFCs) from aluminium producers have been reduced by 43 since 1985.

32. All major classes of hydrocarbons have been found at low concentrations in the Antarctic ecosystems.

A4.3.8.3.1 Consistent with good occupational hygiene practices, personal protective equipment (PPE) should be used in conjunction with other control measures, including engineering controls, ventilation, and isolation. See also Section 5 Fire fighting measures of the SDS for specific fire chemical PPE advice.

Concentrations of the breakdown products (oxidation products) of oil were found to be about 10 times higher than concentrations of their parent hydrocarbons.

data on emissions of other GHG (eg PFCs, HFCs, SF6), specifically

And we've learned that, in this species and I suspect in others as well these hydrocarbons, this layer of grease on the outside of ants, is different as ants perform different tasks.

As far as other major hydrocarbons, namely coal and radioactive minerals, are concerned, there are virtually no known deposits in most of the small island countries.

This dialogue, which already covers topics relating to living resources, could be extended to such other areas as hydrocarbons and communications.

Argentine and British delegations are meeting this week in Buenos Aires in order to find new ways of cooperating in the exploration and exploitation of hydrocarbons.

For example, a number of research institutions across developing countries have discovered the medicinal uses of aromatic and medicinal plants, but are unable to commercialize those findings.

Island arc basins in the Caribbean Sea and the south west Pacific have been investigated for their hydrocarbon potential.

And we've learned that, in this species and I suspect in others as well these hydrocarbons, this layer of grease on the outside of ants, is different as ants perform different tasks.

Rising oil prices are due to the sharp increase in demand by the major consumers, which have not adopted effective policies to reduce their dependency on hydrocarbons.

Working in conjunction with risk management software, the sensor system was reducing the risk of potential environmental contamination from hydrocarbon spillage.

The quot new quot fluoridized gases (PFCs and SF6) together contribute 8 of the total emissions.

Eight reports to the working party on the chemical industry on surveys of the chemical industry (two) aromatic hydrocarbons and olefins (two) chemical producers and products (two) chemical legislation and environmental clean up.

The low levels of natural hydrocarbons and restricted human activity make the Antarctic ecosystem suitable as an indicator of global hydrocarbon pollution. 20

What it turned out, that all that we are seeing, all this liquid, is made of hydrocarbon and ethane and methane, similar to what you put in your car.

George A. Olah prepared the so called magic acid, so named for its ability to attack hydrocarbons, by mixing antimony pentafluoride (SbF5) and fluorosulfonic acid (FSO3H).

We regret, however, the specific focus on that issue, since safety and security measures in general should be strengthened for the maritime transportation of all hazardous materials and pollutants, particularly hydrocarbons.

5. Seminars and training programmes will be conducted in illicit growing areas to motivate women with respect to entrepreneurship and the possibilities of small scale processing of food, spices, and aromatic and medicinal plants.

Photolysis in the atmosphere Photolysis also occurs in the atmosphere as part of a series of reactions by which primary pollutants such as hydrocarbons and nitrogen oxides react to form secondary pollutants such as peroxyacyl nitrates.

Projections of emissions of the perfluorinated carbons (CF4 and C2F6), sulphur hexafluoride (SF6) and HFCs have been prepared on the basis of figures collected from the relevant branches and industrial enterprises.

In 1960, with a newly installed democratic government, Hydrocarbons Minister Juan Pablo Pérez Alfonso led the creation of OPEC, the consortium of oil producing countries aiming to support the price of oil.

In that regard, the situation has unfortunately been affected recently by unilateral positions taken by the British Government on the sensitive matters of hydrocarbons quot .

2 HOCl Cl2O H2O K (0 C) 3.55x10 3 dm3 molDespite this, it has been suggested that dichlorine monoxide may be the active species in the reactions of HOCl with olefins and aromatic compounds, as well as in the chlorination of drinking water.

Oil and gas production activities, including burning of oil and gas on stationary and mobile oil rigs, emissions from gas processing and leakage of hydrocarbons, accounted for about 23 .

Among them were understandings on confidence building measures in the military sphere, conservation of fishing resources, exploration of hydrocarbons, air and sea access and communications with the Malvinas Islands, and the construction of a war memorial at Darwin for the Argentines fallen in the 1982 conflict.
