0 a chemical combination of hydrogen and carbon, such as in oil or petrol:
hydrocarbon emissions
1 a chemical combination of hydrogen (= a gas) and carbon (= a chemical element that is in all animals and plants), found in fuels
2 a chemical combination of hydrogen and carbon, such as in oil or petrol:
Hydrocarbon and carbon monoxide emissions from automobiles.
The stoichiometry of the exact reaction will depend on the nature of the organic matter involved, here assumed to be saturated aliphatic hydrocarbon.
There is a need to understand the fate and behaviour of hydrocarbon contaminants in these extreme systems.
The total quantity of hydrocarbons (sum of single hydrocarbon quantity) is expressed here as quantity of hydrocarbons in ng/mg of insect.
The proportions of these hydrocarbons increased in extracts of parasitized honey bees.
The highest increase among relative proportions of hydrocarbons was observed with unsaturated hydrocarbons (around 15 % versus 9 %).
Maturation of the organic matter in the vicinity of the intrusion can lead to the generation of liquid hydrocarbons.
Nevertheless, the effect of evaporation and other natural degradation processes through the years might have contributed to lower hydrocarbon concentrations.
There is a significant reduction in hydrocarbon concentrations in sediments as the distance from the assumed hydrocarbon sources (contaminated sites located uphill) increases.
