Hong Kong is one of the most densely populated cities in the world, with millions of people living and working in close proximity to busy roads with severe air pollution. Among the various air pollutants, surface ozone is of particular concern.

A research team led by Professor Amos Tai successfully quantified and visualised the impact of Hong Kong air pollution, especially ozone pollutants, on plants and the environment. The first plant-based measurement of ozone in the southern China region shows that the ozone level in Hong Kong is high enough to cause significant damage to plants, even in the countryside. The findings have important implications for farmers in Hong Kong and southern China, where their crops suffer from ozone pollution.
