Cutting ammonia pollution may lead to more acid rain in China

China’s plans to cut ammonia emissions to reduce haze pollution may worsen the country’s acid rain problem, a new study has found. To evaluate the potential impact of the government’s plans to reduce ammonia in the atmosphere, a team of researchers in China used models to predict how these cuts would affect haze pollution and acid rain. Over the last few decades, as a result of growing industrialisation, China has seen increased air pollution and acid rain, both of which are harmful to human health and the environment.
