摘要

Anthropogenic particles occur in various aquatic environments, and rainwater acts as a carrier of these contaminants by incorporating them into water droplets. To test the potential of rainfall to remove airborne particles, rainwater was collected three times during the rainy season in the municipality of Macapá, Amapá, Brazil. Chemical digestion and filtration protocols were applied to identify particles. A total of 225 ml of rainwater yielded 194 particles. Particle abundance increased with the number of preceding rain-free days, suggesting that rainfall may contribute to the atmospheric removal of these particles.
