The Andhra Pradesh Pollution Control Board has leveled allegations of pollution against various bulk drug units manufacturing drugs in excess of the permitted quantities.

The charges also include pharmaceutical firms responsible for unauthorised manufacture of these drugs. Despite permission being taken to manufacture a certain quantity and category of drugs, these units allegedly exceed the prescribed limit, by more than 30 per cent in certain cases. The huge amount of resultant effluents are not treated and the excess drugs, according to the APPCB, add to the pollution in the city.
