Urban environments that are already polluted can interact with polluting particles to create more intense smog and haze, according to scientists in China and the Houston . Climate change also factors into the formation of haze. The researchers analysed the morphology of black carbon, a pollutant that contributes to haze, global warming and the ultra fine particulates, PM2.5, which can cause human respiratory problems. The morphology modification of black carbon occurred in just 4 to 6 hours in China , 500 times more quickly than in China , which has cleaner air. Scientists have said it is important to investigate the interaction of primary pollutants with specific atmospheres in order to tackle air pollution.
