Article Synopsis
- Stormwater runoff in urban areas poses a nonpoint source pollution risk, leading to degradation of aquatic ecosystems, particularly due to high levels of total solids and metals.
- In a study conducted at a car parking lot in São Paulo, Brazil, researchers monitored 12 rain events to analyze the runoff's composition and its response over time, finding that several metals exceeded the country's water quality standards.
- The study revealed that different pollutant sources could be identified based on seasonal changes, rainfall intensity, and the influence of local activities, with higher heavy metal concentrations linked to specific atmospheric conditions during winter.
Industrial foundry processes release metal dust and fumes into the environment. Our study evaluated the exposure to potentially toxic elements in foundry workers. The assessed samples consisted of air particulate matter (n = 42), urine (n = 194), and blood (n = 167).
