Continuing discharges into the river will flow into the bay, disrupting its ecological balance and leaving it as toxic as the estuaries adjacent to Manhattan...

The microorganisms move up the food chain into fish, and man eats the fish. Heavy doses of mercury can result in nervous-system damage, even death. Lead, long a factor in urban air pollution, has now been found in the oceans. The upper layers of the oceans seem to be polluted with industrial lead, says the report, and "atmospheric levels...
