Especially the reference of the study is most convincing.

NO, I think not.

After absorption in the body by four ways, each type of mercury undergoes a
specific metabolism. Elementary mercury as mercury vapour becomes rapidly
oxidized to Hg2+ and, afterwards, is metabolized as an inorganic mercurial
compound. From the blood circulation mercury reaches target organs like the
kidneys, the central nervous system, the liver and the hypophysis, in which
mercury accumulates. The retention time varies by organ and is longest in
the brain. Mercury is mainly eliminated with urine and faeces, to a lesser
degree with transpiration and mother's milk and sometimes by respiration.

.1.2. Elemental mercury is also poisonous to the nervous system. Humans are
mainly exposed by inhaling vapours. These are absorbed into the body via the
lungs and move easily from the bloodstream into the brain. However, when
elemental mercury is ingested, little is absorbed into the body. The
inhalation of elemental mercury vapours can cause neurological and
behavioural disorders, such as tremors, emotional instability, insomnia,
memory loss, neuromuscular changes and headaches. They can also harm the
kidneys and thyroid. High exposures have also led to deaths.

Dental Amalgam Fillings is the Number One Source of Mercury in People
and
Exposure Exceeds Government Health Standards for Inorganic mercury (vapor)

Supplied by one of our readers     Government agencies and medical studies
have found that the number one source of mercury in people is from dental
amalgam fillings2-20. Exposure from fillings amounts to from 50 to 90
percent of exposure, with the average being about 80 % of total
exposure5-9,12-15,19,20. The studies found that mercury amalgams are
unstable due to mercury's low vapor pressure and galvanic action, leaking
mercury vapor continuously into the lungs and saliva at levels exceeding
health standards.
   Mercury exposure of most people with fillings was found to exceed
government health standards and levels found to cause adverse health
effects(see below).
   The U.S.EPA mercury health standard1 for elemental mercury
exposure(vapor) is 0.3 micrograms per cubic meter of air(0.3 ug/M3). For the
average adult breathing 20 M3 of air per day2, this amounts to an exposure
of 6 micrograms(ug) per day.
   The corresponding tolerable daily exposure developed in a report for the
Canadian Health Agency, Health Canada, is .014 ug/kg body weight or 1 ug/day
for average adult2. The U.S. Agency for toxic Substances and Disease
Registry (ASTDR) standard (MRL) -for acute inhalation exposure to mercury
vapor is 0.02 micrograms Hg/m3, which translates to approx. 1.2 ug/day for
the average adult.
   The range of mercury exposure levels found in people with amalgam
fillings by the World Health Organization Scientific Panel on Mercury was 3
to 70 micrograms per day3, with other medical studies finding up to 200
ug/day in gum chewers or people who grind their teeth6,11,16,17,18.
   The average exposure was above 10 ug/day3-18. The average mercury
exposure for a Canadian adult with amalgam fillings was found in the Health
Canada study to be 9 ug/day2. In a large German study with 20,000 tested
subjects at a University Medical Clinic, the average exposure from fillings
was over 10 ug/day and over 50 % of all those with 6 or more amalgam
fillings had daily exposure exceeding the EPA health guideline17.
   Studies have consistently found modern high copper non gamma-two
amalgams have greater release of mercury vapor than conventional silver
amalgams21-23. Recent studies have concluded that because of the high
mercury release levels of modern amalgams, mercury poisoning from amalgam
fillings is widespread throughout the population"17,22,18.
   Common levels found in persons with amalgam fillings are over 10 times
the Health Canada TDE, and more than the EPA health standard for mercury
vapor. Thus persons with amalgam fillings have levels of intraoral mercury
vapor and body exposure levels higher than the level considered to have
significant health risk.
   The studies found that Total mercury intake is proportional to the
number and extent of amalgam surfaces, but other factors such as chewing gum
and drinking hot liquids influence the intake significantly increasing
exposure as much as 500%. ).
   A World Health Organzation Scientific Panel concluded that a safe level
of mercury exposure below which no adverse effects occur has never been
established3.
