TL;DR: The utility of coordinating global sensing of environmental contaminants efforts through integration of environmental monitoring and specimen banking to identify regions for implementation of more robust environmental assessment and management programs is highlighted.

TL;DR: Research continues to identify environmental compartments—including stormwater runoff, lake sediment, soil, house dust, and most recently, air—contaminated by PAHs from coal-tar-based sealcoat and to demonstrate potential risks to biological communities and human health.

TL;DR: The results indicate that the presence of coal-tar-based pavement sealants is associated with significant increases in estimated excess lifetime cancer risk for nearby residents.

TL;DR: Using screening values created using probabilistic ecotoxicological hazard assessment approaches using chemical toxicity distributions could support the processes of data dossier development and environmental exposure assessment, allowing for rigorous prioritization in testing and monitoring to fill data gaps.

TL;DR: A framework for future experimental studies to support risk-based assessments of street cleaning technologies is provided and regenerative air street sweepers appear to provide the most benefit with regard to collection of small particles and prevention of re-entrainment.
