China’s toxic smog is affecting foetal health, two new studies show, adding to pressure on the government to tackle the harmful levels of pollution that are becoming a political liability.
A study of women who were pregnant during the 2008 Beijing Olympic Games, when the city reduced car traffic and halted many industrial plants in surrounding provinces, shows their babies had significantly higher birth weights than those born the year before or after.
Research is slowly highlighting the health effects of the headlong rush to industrialise. Public dissatisfaction at persistent smog is growing, especially among the capital’s wealthier residents. Provincial cities routinely fail to meet China’s own standards for air quality.
