BAYPORT, Texas (AP) Officials say air monitoring hasn't raised health concerns as the cleanup continues following a collision at a busy commercial waterway near Houston involving four vessels that caused a toxic gasoline product to leak into the water.
Authorities said at a news conference 2,700 air samples were tested and none have exceeded levels to cause concern.
Residents around the accident site have reported a gasoline smell.
Officials say the spilled product can be hazardous.
Friday's accident near Bayport between a tanker that punctured storage tanks on a tugboat pushing two barges along the Houston Ship Channel released 9,000 barrels of a gasoline blend stock.
Crews are working to remove the gasoline product from the barges.
The ship channel remains partially closed.
The cause of the collision is being investigated.
