'This will be the year when the secretary for transport will feel the heat, as she will be called into account. The chief secretary will have to bang heads in the transport, environment and development offices to get results.' Christine Loh Kung-wai, head of the Civic Exchange, on her views on air pollution in 2010 Background Air pollution is affecting all of us. It is the No 1 health risk in Hong Kong. Loh says Eva Cheng will 'feel the heat, as she will be called into account'. This means Cheng will need to explain to the government and the public what she did to reduce air pollution in Hong Kong. Loh thinks this will put her in an uncomfortable position because she hasn't done much. To 'feel the heat' means to feel pressure. Loh says Henry Tang Ying-yen will 'have to bang heads ... to get results'. This means Tang will probably have to get tough with officials if he wants to make some changes.
