Exempel på hydrocarbon

• 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.

• Table 1 shows the hydrocarbon quantities given as the mean nanograms per fly of each compound or mixture from the two peaks of interest.

• Parasites, if they possess quantities of epicuticular hydrocarbons near the threshold level necessary to be perceived by hosts, could be more tolerated by hosts.

• No qualitative differences in the hydrocarbon profiles was observed with regard to gender though preliminary results showed that quantitative differences were clearly present.

• Issues and problems relating to fishing, hydrocarbon exploration, tourism and communications clearly spill over national borders (regardless of whether those borders are actually contested).

• It was postulated that the movement of water through hydrocarbon-contaminated sediments would result in the dispersal of hydrocarbon-contaminated meltwater downhill towards the sea.

• However, hydrocarbon (toluene) emissions were more than 250% higher than total hydrocarbon emissions from other sources on station.

• It will be less useful for those working on oceanic lithosphere, hydrocarbon geology or mineralization processes.
