Summary

This study in rural Guatemala tests whether community education can reduce the burning of plastic waste and lower people's exposure to harmful pollutants. About 400 women and community members from 16 villages will take part, with half attending 12 weekly working groups on waste management and alternatives to burning. Researchers will measure air pollution and urine biomarkers to see if the intervention makes a difference over 12 months.
