Polycyclic Aromatic Hydrocarbons (PAH's)



Chemitrace in collaboration with Bioventix Limited launch a PAH (polycyclic aromatic hydrocarbon) biomonitoring test kit. This kit is a sandwich enzyme-linked immunosorbent for the detection of 1-hydroxypyrene glucuronide (HOP-G) in urine samples. Each kit provides sufficient reagents for the determination of 40 samples run in duplicate.

The polycyclic aromatic hydrocarbons (PAHs) are common industrial chemicals. PAHs are employed in research, medicines, dyes, plastics and pesticides. Exposure to the PAHs is associated with the combustion of fossil fuels. Occupational exposure to PAHs may occur during oil and petroleum refining, aluminium smelting, bitumen processing and road paving. Steel plant and foundry workers can also be exposed to PAHs. Vehicle exhausts are a major source of environmental PAHs. PAH exposure is associated with an increased risk of cancers.

The assessment of occupational and environmental exposure to PAHs is difficult. The determination of airborne PAH levels fails to take into account the potential pathway of skin absorption, which can contribute significantly to the total internal dose. The most widely used biomarker of PAH exposure is urinary 1-hydroxypyrene (1-HP). Urinary 1-HP Biomonitoring Guidance Values have been published.

Chemitrace have developed an ELISA for the laboratory analysis of urinary 1-HP. The results of this work, presented at ICOH 2015, IOHA 2015, BOHS 2016 and Airmon10 in 2022, were well received by professionals working in the field of occupational and environmental health. The  PAH ELISA Test Kit Insert  provides further details of this quick and easy immunoassay.

Chemitrace are also developing a point of care test. This simple and novel “dipstick” will enable on-site testing and real time monitoring allowing employers to demonstrate the immediate impact of good working practice and provide immediate reassurance to workers involved in potentially hazardous tasks.
