Amongst the most common contaminants found in the environment are hydrocarbons from oil and petroleum products. Depending on the oil product these hydrocarbons differ widely from volatile compounds like BTEX to heavy compounds found in bunker fuel.
The instrumentation used by environmental laboratories for hydrocarbon analysis are focused around GC, either with a FID or a MS detector depending on local legislation. The volatile hydrocarbons will be analysed using either headspace or purge and trap while the heavier components will be analysed after solvent extraction
ALS follows international and local standards for testing including EPA and ISO methods.
Some metals like mercury, tin, selenium and arsenic have forms that are more toxic than others like methylmercury. Metal speciation is critical to understand bioavailability, transport and total toxicity.. Click here to find more information about VOC in Groundwater.MORE INFORMATION
