B4567 - Anthropogenic Chemicals and Human Health - Non-invasive Human Biomonitoring Pilot Study - 27/03/2024
This project seeks to develop a non-invasive, human biomonitoring method to assess human exposure to anthropogenically sourced chemicals. In our day to day lives, humans are exposed to a mixture of “man-made” chemicals from the materials we touch, the food we eat or air we breathe. Some of these environmental pollutants may persist and accumulate in the human body, with potentially harmful or unknown health implications. Such chemicals may include pesticides, commercial drugs, flame retardants, combustion products of fuels, plasticisers or cosmetic components. Aside from accumulation in the blood, which would require invasive sampling to assess exposure, some of these anthropogenic chemicals can accumulate in human hair or nails. The focus of this pilot study is to develop an extraction procedure, to separate the target chemicals from hair, and optimised analytical approaches for chemical identification and quantification. For this, hair samples are required for method development. There is potential for this developed method to incentivise funding for additional sampling and analysis of a larger study group. A broader biomonitoring survey may provide valuable insight into chemical exposure sources and persistence both temporally and regionally. Monitoring exposure of chemicals with recognised human health implications may also provide new insight into the incidence of illness and disease.
