Environmental Protection in Urban Areas

Key Challenges

Urban environmental protection faces multiple challenges including air pollution, water resource depletion, and waste management issues.

Air Pollution Sources

• Industrial emissions
• Vehicle exhaust
• Construction dust

Water Quality Management

Urban wastewater treatment systems require continuous improvement to meet environmental standards.

Current Solutions

Green Infrastructure

• Urban tree planting programs
• Permeable pavements
• Green walls construction

Technological Innovations

Advanced oxidation processes (AOPs) have shown strong potential in heavy metal removal (Zhang et al., 2022).

Future Directions

Integrated management systems combining IoT sensors and big data analysis are recommended for sustainable development.
