While urban greenery is known to regulate microclimates and reduce air pollution, its integrated effects remain insufficiently quantified. Through field monitoring ENVI-met 5.1 modeling of high-rise residential areas in Jinan, the results demonstrate that: (1) vegetation exhibits distinct spatial impacts air-quality impacts, reducing roadside PM2.5 by 26.63 μg/m3 while increasing building-adjacent levels 17.5 μg/m3; (2) shrubs outperformed trees reduction (up 65.34%), particularly when planted inner rows, whereas tree crown morphology spacing showed negligible effects; (3) densely spaced columnar optimize cooling, Ta 3–4.8 °C physiological equivalent temperature (PET*) 8–12.8 °C, planting on outer row best balanced thermal improvements; (4) each 1 m2/m3 leaf area density (LAD) increase yields benefits (ΔTa = −1.07 ΔPET* −1.93 °C) but elevates 4.32 μg/m3. These findings provide evidence-based design strategies for sustainable planning.

Stroke is the second leading cause of death worldwide, and exposure to particulate air pollution now recognized as one major modifiable risk factors. However, can vary in terms physicochemical composition exposition specificities. Therefore, its relationships with stroke outcomes remain under intense investigation.

Few studies have found an association between extreme temperature events and increased risk of recurrent ischemic stroke (IS). We examined associations (heat waves, cold spells) IS in Tianjin, China (2019-2020), using a time-stratified case-crossover design, while evaluating greenness's moderating role. Significant heat wave effects peaked at lag 8, with severe intensity increasing recurrence by 39.8% (OR = 1.398, 95% CI:1.032-1.894). Cold spell impacts 3, moderate spells elevating 20.3% 1.203, CI: 1.052-1.377) 98.2% 1.982, 1.407-2.791). Greenness modified these associations: low-greenness areas strengthened effects(lag9:OR 2.309,95%CI:1.024-5.209) but weakened impacts(OR 1.557,95%CI:1.037-2.340), whereas high-greenness attenuated links(lag8:OR 1.402,95%CI:1.022-1.924) nullified associations. Age sex disparities emerged - younger individuals males showed higher susceptibility to older were more vulnerable spells. The findings highlight greenness as potential modifier events-related risks underscore demographic-specific vulnerabilities.
