LAHORE: Justice Atir Mehmood of the Lahore High Court (LHC) Tuesday issued a notice to the government on a petition seeking ban on use of plastic bottles for packaging. A local resident, Tariq Khan, moved the petition. Petitioner claimed that after laboratory tests of bottles of soft drinks, water and cough syrup, heavy metals were found present far beyond permissible limits. He said that excess amounts of metal cause kidney damage, respiratory problems, cancer, stroke and heart trouble as well as spontaneous abortions.
