Assessing the Impact of London's Congestion Charge on Air Quality and Public Health

The video discusses a study by the Environmental Research Group at King's College London, examining the impact of a congestion charge on traffic and pollution in London. The study uniquely combines toxicology and epidemiology to assess air quality and health effects. Preliminary data shows a 30% reduction in traffic, but pollution levels remain high in some areas. The research focuses on the toxicity of pollutants like copper, iron, and PAHs from diesel cars. Despite reduced traffic, air pollution hasn't decreased proportionally.
