The Delhi High Court (HQ recently reserved its order on the import of zinc and lead ash skimmings after hearing a marathon argument on a petition filed by the Zinc Manufacturers Association (ZMA). The HC had imposed an interim ban on the import of these two items on April 22, acting on a petition filed by the Public Interest Legal Support and Research Centre, which alleged that these substances were highly toxic. However, the ZMA said that the ban should not be extended as many international environmental organisations had declared them to be non-hazardous.
