["Dr Alex Laffbridge's Brought to you by Chemistry episode with Audrey Denazel argues that air-quality policy works when cities make the healthy choice easier than driving.", "Denazel, a senior lecturer at Imperial College's Center for Environmental Policy, says transport is the biggest city source of air pollution, while shipping, agriculture, industry, and meteorology shape local differences.", "Asked about London's ULEZ, she says the right evaluation is a natural experiment with before-and-after measurements and a comparable control area without the policy.", "She closes by linking 15-minute cities, bike lanes, sidewalks, trees, green space, and public transport to children's health, climate goals, and more liveable streets."]

["Brought to you by Chemistry's '4.2 How can we improve indoor air quality?' moves Dr Alex Lathbridge's series from outdoor pollution to the air inside homes, offices, and public buildings.", "Kath Noakes, a Professor of Environmental Engineering for Buildings at the University of Leeds, and Nick Carslaw, a Professor of Indoor Air Chemistry at the University of York, explain why indoor exposure changes by room, building, and activity.", "They point to the 90% of time people spend indoors, cooking and cleaning as major sources, and a European study that has already measured about 800 indoor chemicals, including formaldehyde.", "The practical guidance is direct: use cooker hoods or open windows, ventilate after cooking, keep cleaning and scented products in moderation, and design buildings that balance net-zero goals with healthy air."]

Dr Alex Lathbridge interviews atmospheric chemist Neil Donoghue of Carnegie Mellon University and environmental-health researcher Suzanne Bartington of the University of Birmingham about what air pollution is and how it affects health.
