...deadly marine impact of nitrogen, mainly from fertilizer runoff, sewage and animal wastes, has been recognized for years. But the E.D.F. study is the first to pinpoint acid rain as an important source of coastal pollution. Any overload of nitrogen feeds marine algae, which bloom into vast growths that block sunlight and deplete the oxygen supply, smothering fish and crustaceans. The E.D.F. reports that 25% of the nitrogen contaminating Chesapeake Bay is the result of acid rain; investigators found similar nitrogen levels in a preliminary study of the coastal waters of New York and North Carolina. The proposed solution: tighter...
