Seven Substances Added to 14th Report on Carcinogens

Five viruses, a chemical, and a metallic element
listed in new HHS report

Today's release of the U.S. Department of Health and Human Services
14th Report on Carcinogens includes seven newly reviewed substances,
bringing the cumulative total to 248 listings.

The chemical trichloroethylene (TCE), and the metallic element cobalt
and cobalt compounds that release cobalt ions in vivo, are being
added to the list, as well as five viruses that have been linked to
cancer in humans. The five viruses include human immunodeficiency
virus type 1, human T-cell lymphotropic virus type 1, Epstein-Barr
virus, Kaposi sarcoma-associated herpesvirus, and Merkel cell
polyomavirus.

Trichloroethylene (TCE)

Trichloroethylene (TCE) is an industrial solvent used primarily to
make hydrofluorocarbon chemicals. It is being listed in the Report
on Carcinogens as a known human carcinogen. Since 2000, TCE had
been listed as a reasonably anticipated human carcinogen. However,
numerous human studies showing a causal association between TCE
exposure and an increased risk for kidney cancer have led NTP to
reevaluate and reclassify TCE as known to be a human carcinogen.
There are many ways people can be exposed to TCE. It can be released
into the air, water, and soil at places where it is produced or used.
It breaks down slowly and can move readily through soil to make
its way into underground drinking water sources. Because of its
widespread use as a metal degreasing agent to maintain military
equipment, it has been found in the groundwater at many military
and Superfund sites.

Cobalt and cobalt compounds that release cobalt ions in vivo

Cobalt and cobalt compounds that release cobalt ions in vivo are
being listed as reasonably anticipated to be a human carcinogen.
The listing for cobalt includes different types of cobalt compounds
that release ions into the body. It does not include vitamin B-12,
because cobalt in this essential nutrient is bound to protein and
does not release cobalt ions. Cobalt is a naturally occurring element
used to make metal alloys and other metal compounds, such as military
and industrial equipment, and rechargeable batteries. The highest
exposure occurs in the workplace and from failed surgical implants.
The listing for this metal and its compounds is based largely on
studies in experimental *******

*GB* azz..... non mastico inglese, cioe ?


PS ma la trieleina cancerogena quindi anche inalata ?

Noooooo!
Di solito quando uno usa la trielina se la inietta endovena :-)
LOL.
