Other claims from this paper (7)
- Intervention effect Traffic-induced air pollution reduced leaf area, stomatal density and cuticle layer thickness of tree species compared with a control campus site.
- Intervention effect Traffic-induced air pollution increased electrolyte leakage across all investigated tree species compared with a control campus site.
- Association Heavy metal concentrations, particularly Pb, in soil and leaf samples increased in correlation with rising traffic congestion.
- Observation All studied tree species responded to traffic-related pollution, with varying response intensity.
- Observation Cupressus arizonica had the highest capacity to absorb and accumulate heavy metals.
- Recommendation Cupressus arizonica is the most tolerant and resilient species and an excellent candidate for planting.
- Observation Cupressus arizonica, Pinus nigra and Robinia pseudoacacia have potential as good bioindicators of urban air pollution.
