Air pollution tops 'alert' level on two days
Air quality worsened slightly last month, with the pollution index passing the benchmark 100 level on two consecutive days, compared with once in June.
Pollution hit a high on July 4 and 5, according to Environmental Protection Department figures.
A reading of 111 was recorded on July 4 at the general station, and 105 was recorded at the Causeway Bay roadside station. The next day at the same roadside station it was 107. The lowest reading was on July 2, when the index registered 26 at the general station and 47 at the roadside.
People with respiratory diseases should take care when the index tops 100.
There were 22 convictions for pollution-related offences, and about 1,532 emission tests were carried out under the smoky vehicle control programme - 463 vehicles failed.
