A New Jersey Health Department survey finds the majority of residents in a town where a train derailed and released a noxious gas reported new or worsening health problems within weeks.
The state report was posted last week on the website of the National Transportation Safety Board, which is investigating the November 2012 accident in Paulsboro.
The survey reached residents of the town near Philadelphia in person and by mail in the weeks after vinyl chloride was released.
Residents reported upper respiratory problems, dizziness and eye irritation.
Symptoms were reported most often by those who were closest to the spill.
