Willows and poplars worsen city air quality by releasing ozone-forming compounds
A Nature study finds that trees widely planted in cities release isoprene, a volatile organic compound that creates ground-level ozone, with warming expected to intensify the problem.
What to know
- Willow and poplar trees widely planted in cities release isoprene, a volatile organic compound that forms ground-level ozone when it reacts with nitrogen oxides.
- The problem is particularly acute in megacities like Beijing with millions of these trees.
- Rising temperatures are expected to increase VOC emissions from these trees, worsening urban air quality in a warming climate.

# Beijing # China Between 20C and 35C, the chemical reactivity of the volatile compounds emitted by city trees increased seven to eightfold, scientists found. Isoprene emissions in Beijing were the highest among the cities observed, approaching levels found in temperate forests, the study found https://www. independent.co.uk/news/science…

# Beijing # China These trees are making air quality in cities worse Across Beijing, millions of weeping willows and poplar trees turn the megacity into a green metropolis.
