Media credibility rating lowest for three years The credibility of Hong Kong media has dropped significantly in the past six months, reaching the lowest rate in the past three years, a survey by the University of Hong Kong's public opinion programme found. Seventy-four per cent of 1,022 respondents said news media misused or abused the freedom of the press, five percentage points up from April, while 41 per cent of respondents said the media practised self-censorship, up 3 percentage points from the previous survey. The credibility rating dropped from 5.72 to 5.6 on a scale of 10. Pollution law breaches bring 39 convictions Thirty-nine convictions were recorded last month for breaches of anti-pollution legislation. Of these, 23 were under the Air Pollution Control Ordinance, nine under the Noise Control Ordinance, four under the Waste Disposal Ordinance and three under the Water Pollution Control Ordinance. The heaviest fine of $80,000 was imposed on a company that imported controlled waste without a permit.
