Pastel - Model UV HAP -Spectrophotometers
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.
SECOMAM has designed in conjunction with TOTAL and the Ecoles Des Mines d`Ales 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. Furthermore a treatability index informs on the biodegradability of contaminants. The measurement range is between 20 and 2000 mg/kg.
