Question

The storm gutters of a large city empty into an ocean bay. A mechanic shop, unable to afford proper disposal, begins dumping its used car fluids, like motor oil, into the gutters instead. How will this impact the marine life of the bay?

Answer 1

The pollutants will disrupt oxygen absorption in fish

Answer 2

The oil tends to contain toxic substances such as lead, cadmium and chlorine compounds, which has a great capacity for environmental deterioration. This oil produces a waterproof film, which prevents oxygenation and can suffocate the living beings that live there. On the other hand. used oil, having a low biodegradability index, can seriously affect the biological treatments of water treatment plants, even disabling them.
