1. Which SDGs are addressed or connected to the issues highlighted in the article?

1. SDG 3: Good Health and Well-being
   • The article extensively discusses the significant threat urban pollution, specifically micro rubber and vanadium in street dust, poses to public health. It highlights links to respiratory diseases and cardiovascular conditions, emphasizing the risks for vulnerable populations like children and the elderly.
2. SDG 11: Sustainable Cities and Communities
   • The core issue is urban pollution resulting from city life, particularly high traffic volumes. The article calls for better urban planning, traffic management, and dust control measures like street cleaning and vegetation to make cities safer and more sustainable.
3. SDG 13: Climate Action
   • The text explicitly mentions that the effects of climate change, such as rising temperatures and shifting weather patterns, can worsen urban dust pollution by increasing the mobilization of dust particles. It advocates for integrating climate resilience strategies into urban planning.
4. SDG 15: Life on Land
   • The article points out the environmental dimension of the problem, where contaminated dust runs off into nearby soil and water bodies. This introduction of toxic materials can harm biodiversity, disrupt food chains, and affect terrestrial ecosystems.

2. What specific targets under those SDGs can be identified based on the article’s content?

1. Target 3.9: By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination.
   • The article directly aligns with this target by investigating the health implications of harmful particles (micro rubber and vanadium) in urban dust. It calls for preventative measures to combat the adverse health effects, such as respiratory and cardiovascular diseases, caused by this form of pollution.
2. Target 11.6: By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management.
   • The research focuses on a key aspect of urban environmental impact: pollution from street dust linked to traffic. The call for dust control measures, better urban planning around traffic patterns, and regular street cleaning are direct strategies to improve urban air quality and reduce the city’s negative environmental footprint.
3. Target 13.2: Integrate climate change measures into national policies, strategies and planning.
