Sitelab's laboratory performed a 4 day site investigation testing PAHs in sediment on the West Branch Grand Calumet River in Indiana. Test data was used to fingerprint and map the river bottom contaminated with heavy crude oil.
New regulations require testing asphalt for PAHs. Sitelab's UVF-3100D and TD-500D analyzers can test asphalt quickly and accurately. Results takes less than 5 minutes. The equipment is easy to operate.
There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content. In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff. Sitelab can be used to quickly check the concentrations of polycyclic aromatic hydrocarbons and determine if it's made from coal tar or alternative petroleum based black top sealants. Got samples? We'll test them for free! Contact Sitelab Corporation for details.
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.
