XYLENE FACT SHEET
Brief Overview:
Contaminant: Xylene
Category: Organic
MCL: 10000 PPB
Source: Solvents, gasoline, plasticizers
Effect: Damage to the central nervous system, liver and kidneys
Followup: Treat and retest quarterly
Treatment: Granular activated charcoal
Details:
Source: A xylene is any of a group of very similar organic compounds. They are
clear liquids with a sweet odor. The greatest use of xylenes is as a solvent
which is much safer than benzene. Other uses include: in gasoline as part of the
BTX component (benzene-toluene-xylene); Xylene mixtures are used to make
phthalate plasticizers, polyester fiber, film and fabricated items.
Production of xylenes was 6.84 billion lbs. in 1993. Major environmental releases
of xylenes are due to evaporation from the refining and use of petroleum
products. It may also be released by leaks or spills during the transport and
storage of gasoline and other fuels. Xylenes are a natural products of many
plants, and are a component of petroleum and coal tar.
From 1987 to 1993, according to EPA's Toxic Chemical Release Inventory, xylene
releases to land and water totalled nearly 4.8 billion lbs. These releases were
primarily from petroleum refining industries. The largest releases occurred in
Texas. The largest direct releases to water occurred in New Jersey and Georgia.
What happens to Xylene when it is released to the environment? Most of the
xylenes are released into the atmosphere where they are quickly degraded by
sunlight. When released to soil or water, xylenes will quickly evaporate. They
may leach into ground water and persist there for several years. There is little
potential for accumulation in aquatic life.
Effect: Short-term: EPA has found xylenes to potentially cause the following
health effects when people are exposed to it at levels above the MCL for
relatively short periods of time: disturbances of cognitive abilities, balance, and
coordination.
Long-term: Xylenes has the potential to cause the following effects from a
lifetime exposure at levels above the MCL: damage to the central nervous
system, liver and kidneys.
Followup: Treat and retest quarterly.
Treatment: Granular activated charcoal in combination with Packed Tower
Aeration.

Did you catch in the above link, that the man who caused the China spill, was found dead?
I didn't see, why N.Y. would keep smelling.
I did post the effects sheet, mind and liver, with those destroyed, you have real problems.
I would expect the Gov. offices to know who was using enough to smell in the whole area.
