Sorry, Sir, but there you are mistaken. The laws and rules
for environmental poisoning AT WORK are quite different
from those in NORMAL life, like at home.
Yes, those who work in the mercury industry have much higher
mercury loads and much higher mercury excretion than those
who don't but only have amalgams. And amongst th workers it
is only those with the highest urinary mercury excretions
who show deleterious effects.

health impairment from them .
There is a key error in all those studies : They do not
have enough material for comparison. If more than 90
percent of the population are affected, you do not have
enough probands for long-term studies.
No problem. You determine whether there is a correlation
between symptoms and number of amalgam surfaces, or daily
mercury excretion. This has been done and there is none.
Here is an example of such a study ---

There is widespread concern regarding the safety of silver-
mercury amalgam
dental restorations, yet little evidence to support their
harm or safety. We
examined whether mercury dental amalgams are adversely
associated with
cognitive functioning in a cross-sectional sample of healthy
working adults.
We studied 550 adults, 30-49 years of age, who were not
occupationally
exposed to mercury. Participants were representative of
employees at a major
urban medical center. Each participant underwent a
neuropsychologic test
battery, a structured questionnaire, a modified dental
examination, and
collection of blood and urine samples. Mercury exposure was
assessed using
a) urinary mercury concentration (UHg); b) the total number
of amalgam
surfaces; and c) the number of occlusal amalgam surfaces.
Linear regression
analysis was used to estimate associations between each
marker of mercury
exposure and each neuropsychologic test, adjusting for
potential confounding
variables. Exposure levels were relatively low. The mean UHg
was 1.7 micro
b/g creatinine (range, 0.09-17.8); the mean total number of
amalgam surfaces
was 10.6 (range, 0-46) and the mean number of occlusal
amalgam surfaces was
6.1 (range, 0-19). No measure of exposure was significantly
associated with
the scores on any neuropsychologic test in analyses that
adjusted for the
sampling design and other covariates. In a sample of healthy
working adults,
mercury exposure derived from dental amalgam restorations
was not associated
with any detectable deficits in cognitive or fine motor
functioning.

Quoted message said:Do you remember the coffee-study in scandinavia, which
lasted about 20 years ? The key error there was that they
studied the effect of coffee, and did not consider that
coffee is drunk at a high temperature, which will vaporize
mercury from amalgam fillings. The result of the study is,
that the more coffee is drunk, the more problems with
joints occur (if I remember this point correctly).
We now could claim, that this result was caused NOT by the
ingredients of the coffee, but by dental amalgam being
vaporized by hot coffee. The studies done by Tekran
support this.
BUT, this still is no proof, as we need a study, lasting
about 20 years with persons who never had and in these
20 years never will have dental amalgam. And we need
another group which drinks another HOT drinks, but no
coffee. How many millions people to you need to start
with, to get this study done... ? Too many.. So it will
never be done...
Or you you can just try and show if the presence of amalgams
has any correlation with poor health, coffee or no.
Here is the closest we have to a prospective study looking
at a wide variety of symptoms, mortality and blood tests.

Serum mercury concentration in relation to survival,
symptoms, and diseases: results from the prospective
population study of women in Gothenburg, Sweden.

[Medline record in process]
A prospective population study of women in Gothenburg,
Sweden was started in 1968-69 and comprised 1462 women aged
38, 46, 50, 54, or 60 years at baseline. Follow-up studies
were carried out in 1974-75, 1980-B11, and 1992-93. The
baseline study included an extensive medical and dental
examination. Serum mercury concentration (beta-HG) was
determined in deep-frozen samples from all participants in
1968-69 and in a random subsample of sera from participants
in 1980-81, about 20 years after the baseline examination.
S-Hg was statistically significantly correlated with number
of amalgam fillings at both examinations. Of 30 defined
symptoms and 4 different clusters of symptoms, no one was
independently correlated with S-Hg measured in the samples
from 1968-69, while there was a negative statistically
significant correlation with over-exertion and poor appetite
in 1980-81. Blood hemoglobin and serum B-12 concentrations
in 1968-69 were statistically significantly and positively
correlated with S-Hg, while erythrocyte sedimentation rate
and the serum concentrations of potassium and triglycerides
were significantly and negatively correlated with S-Hg, also
after including potential confounders. Blood hematocrit
examined in 1980-81 was negatively correlated with S-Hg.
When including potential confounders, serum IgA was also
statistically significantly correlated with S-Hg, but not in
univariate analysis. No statistically significant
correlation was observed between S-Hg, on the one hand, and
the incidence of diabetes, myocardial infarction, stroke, or
cancer on the other, while a statistically significant
negative correlation was observed with overall mortality
when age and education were included as background
variables. There were some correlations between biological
variables and S-Hg, probably of no negative clinical
significance, and we conclude that there is no association
between disease and S-Hg on a population basis in middle-
aged and older women.

Quoted message said:One study only, which has never been replicated, purports
to find a statistical correlation of minor
neuropsychiatric abnormalities on sophisticated testing
with mercury levels that can theoretically be approached
by mercury release from a lot of amalgams. The same

illness from them.
As for some years now I deal with other topics : which
study do you mean ?

OBJECTIVES: To assess early effects on the Central Nervous
System due to occupational exposure to low levels of
inorganic mercury (Hg) in a multicenter nationwide cross-
sectional study, including workers from chloro-alkali
plants, chemical industry, thermometer and fluorescent lamp
manufacturing. The contribution of non-occupational exposure
to inorganic Hg from dental amalgams and to organic Hg from
fish consumption was also considered. METHODS:
Neuropsychological and neuroendocrine functions were
examined in a population of 122 workers occupationally
exposed to Hg, and 196 control subjects, not occupationally
exposed to Hg. Neuropsychological functions were assessed
with neurobehavioral testing including vigilance, motor and
cognitive function, tremor measurements, and with symptoms
concerning neuropsychological and mood assessment.
Neuroendocrine functions were examined with the measurement
of prolactin secretion. The target population was also
characterized by the surface of dental amalgams and sea fish
consumption. RESULTS: In the exposed workers the mean
urinary Hg (HgU) was 10.4 +/- 6.9 (median 8.3, geometric
mean 8.3, range 0.2-35.2) micrograms/g creatinine, whereas
in the control group the mean HgU was 1.9 +/- 2.8 (median
1.2, geometric mean 1.2, range 0.1-33.2) micrograms/g
creatinine. The results indicated homogeneous distribution
of most neurobehavioral parameters among exposed and
controls. On the contrary, finger tapping (p < 0.01) and the
BAMT (Branches Alternate Movement Task) coordination test (p
= 0.05) were associated with occupational exposure,
indicating an impairment in the exposed subjects. Prolactin
levels resulted significantly decreased among the exposed
workers, and inversely related to HgU on an individual basis
(p < 0.05). An inverse association was also observed between
most neuropsychological symptoms and sea fish consumption,
indicating a "beneficial effect" from eating sea fish. On
the contrary, no effects were observed as a function of
dental amalgams. CONCLUSIONS: In conclusion, this study
supports the finding of early alterations of motor function
and neuroendocrine secretion at very low exposure levels of
inorganic Hg, below the current ACGIH BEI and below the most
recent exposure levels reported in the literature.
There is another, that I cannot turn up for now, but which
will be in the archives of this group.

Yes, the old problem : no valid diagnoses - because of god-damned-
stupid "healers" and "medical doctors"... People are ill
and seek the cause for their illnesses and - as being
laymen - are ripped off by the whole health scene...
The key here is that the good medical doctors do not fight
fiercely enough for scientific medicine, but instead help
to cover up the criminals, MDs and "healers" the like...
