There's still no information about other oil-related air toxic chemicals such as naphthalene or hydrogen sulfide, offshore.
The discovery that a special kind of naphthalene with a single extra proton is out in space is important to those studying interstellar regions for many reasons.
The soil has low levels of lead and semi-volatile chemicals, such as naphthalene, which also need to be addressed.

A natural component of crude oil, 2-methylnaphthalene is structurally related to naphthalene, an ingredient in mothballs and toilet-deodorant blocks that is considered a possible human carcinogen by the EPA.
(As product recalls pile up, consumers risk getting lost) "It is really troubling that you've got this form of naphthalene that's produced in millions of pounds a year and we don't have some of the basic information about how toxic it is," said Erik Olson, an expert at the Pew Charitable Trusts, which is advocating an overhaul of U.S. chemical laws.
'Petroleum distillate' is a blanket term that could be used to describe a wide range of chemical substances, many of which are as toxic as "naphthalene, xylene, toluene, and benzene ... methane, propane, and kerosene."
