Authorities near Paulsboro, New Jersey, said the accident occurred early in the morning, causing seven train cars to derail and sending three into the water.
"Several cars had vinyl chloride and only one of those cars went into the water and lost some of its cargo and released some of the vinyl chloride into the air. That vinyl chloride has dissipated at this point," he said. "It's really a minimal environmental or health issue at this point."
According to Ragonese, 22 people went for doctor's check-ups but there were only "minor" injuries.
