Kit PAH for Soil Analysis
Fast & field measurement of Polycyclic Aromatic Hydrocarbons
A growing concern
Soil assessment and remediation markets are expanding in industrial countries,
as soil protection has become a major issue of the environmental policies.
Polycyclic Aromatic Hydrocarbons (PAHs) are considered as priority pollutants
since some of them are expected to be carcinogens. PAHs are formed during the
incomplete burning of coal, oil and gas, or other organic substances. Many
industrial sites are contaminated by PAHs.
An unsatisfied need
Investigation of contaminated soils, assessment of treatment processes and
environmental monitoring of remediated soils require screening many samples.
Laboratory analyses (liquid or gas chromatography) are expensive, time consuming
and the procedures are not suitable for field conditions. Moreover immunoassay
field tests give only qualitative or semi-quantitative results. That's why there
was a lack of fast PAH quantification kit in the market.
A new solution
SECOMAM has designed in conjunction with TOTAL and the Alès School of Mines a
simple, fast, accurate and portable method for field PAH quantification. Based
on the UV spectrophotometric analysis of a soil organic extract, the PAH
concentration is estimated on site within 20 minutes. It refers to the 16 PAHs
included in the US Environmental Protection Agency Priority Pollutants List. The
detection limit is 20 mg/kg. Furthermore a treatability index informs on the
biodegradability of contaminants.
A validation study carried out on several contaminated soils from different
origins shows a very good correlation between the UV field method and the
standard laboratory methods.
The PAH kit comes complete with all materials required to implement 20 tests. A
consumables kit for 20 additional tests is available upon request from SECOMAM.
Time and money savings compared to laboratory analyses
On site and at a lower cost, the PAH kit allows to diagnose in 20 minutes a PAH
soil contamination, to point out the polluted area precisely and to sort
contaminated lands for treatment. It can be used also to follow up
rehabilitation works and to survey the natural attenuation into a PAH
