The National Green Tribunal (NGT) issued notices to the central and Delhi governments over the chemical gas leak from the Tughlaqabad container depot that affected over 450 school children.
The tribunal also issued a show cause notice to the Container Corporation of India asking why its Tughlaqabad unit should not be not shifted to some other place.
On Saturday, over 450 students studying in schools close to the depot had to be hospitalised following the chemical spill.
