Toluene abuse markers in marginalized populations

Area of Science:

• Environmental Health
• Toxicology
• Public Health

Background:

• Toluene abuse is a prevalent addiction within marginalized Roma communities.
• Understanding exposure levels is crucial for targeted health interventions.
• The HEPA-META project focuses on mapping health issues in these populations.

Purpose of the Study:

• To compare urinary toluene metabolite levels between marginalized Roma and the majority population in Eastern Slovakia.
• To assess the accuracy of self-reported toluene abuse through biomarker analysis.
• To investigate potential environmental and lifestyle factors influencing metabolite levels.

Main Methods:

• Biochemical analysis of urinary hippuric acid and o-cresol levels.
• Participant recruitment from marginalized Roma and majority populations in Eastern Slovakia (n=770).
• Utilized data from the HEPA-META project for population health mapping.

Main Results:

• Statistically significant differences in hippuric acid and o-cresol levels were observed between the Roma and majority populations.
• Biomarker levels suggest higher toluene exposure in the marginalized Roma group.
• Questionnaire data on toluene abuse requires careful interpretation due to potential confounding factors.

Conclusions:

• Urinary toluene metabolite levels differ significantly between marginalized Roma and the majority population.
• Biomarker analysis provides objective data on toluene exposure, complementing self-reported information.
• Diet, medical treatment, and alcohol consumption may influence hippuric acid levels, necessitating comprehensive assessment.
