Fifty-three polluters were convicted in July for breaching anti-pollution laws the Environmental Protection Department enforces.

Among them, 21 were convictions made under the Air Pollution Control Ordinance, 13 under the Waste Disposal Ordinance, 11 under the Noise Control Ordinance, six under the Water Pollution Control Ordinance and two under the Dumping at Sea Ordinance.

One company was hit with two fines of $50,000 - the heaviest fine for July - for using powered mechanical equipment and carrying out construction works without a valid construction noise permit.
