Toxicological Information:HEALTH EFFECTS: SILICON DIOXIDE: AN
EPIDEMIOLOGICAL STUDY WAS CONDUCTED WHICH INCLUDED 165 PRECIPITATED
SILICA WORKERS WHO HAD BEEN EXPOSED FOR AN AVERAGE OF 18 YEARS. NO
ADVERSE EFFECTS WERE NOTED IN COMPLETE MEDICAL EXAMINATION
(INCLUDING CHEST ROENTGENOGRAMS) OF THESE WORKERS. PULMONARY
FUNCTION DECREMENTS WERE CORRELATED ONLY WITH SMOKING AND AGE BUT
NOT WITH THE DEGREE OR DURATION OF DUST EXP OSURE. LABORATORY
STUDIES HAVE ALSO BEEN CONDUCTED IN SMALL ANIMALS VIA INHALATION TO
LEVELS OF PRECIPITATED SILICA DUST OF UP TO 126 MG/M3 FOR PERIODS
FROM SIX MONTHS TO TWO YEARS. ALTHOUGH PRECIPITA TED SILICA WAS

Ecological:N/P. TOXICOLOGICAL INFO (CONT): TEMPORARILY DEPOSITED
IN THE ANIMALS' LUNGS, MOST OF THE DEPOSITED MATERIAL WAS CLEARED
SOON AFTER THE DUST EXPOSURE ENDED. THE RESULTS OF ALL STUDIES
PERFORMED BY, OR KNOWN TO, PPG INDICATE A VERY LOW ORDER OF
PULMONARY ACTIVITY FOR SYNTHETIC PRECIPITATED SILICA. DEHP: THE
MAJOR TARGET ORGANS SHOWING DEHP RELATED TOXICITY IN ANIMALS ARE
THE LIVER AND TESTES . DEHP CAUSES LIVER ENLARGEMENT AND PEROXISOME
PROLIFERATION IN RODENTS. VERY HIGH DIETARY LEVELS OF DEHP PRODUCED
LIVER CANCER IN MICE AND RATS OF BOTH SEXES (NTP 4TH ANNUAL REPORT

AND TERATOGENNICITY IN PREGNAT FEMALE RODENTS (ENVIRON. HEALTH
PERSP. 1982, 45% TOX. APP L. PHARCOL. 1980, 53:35-41). THE TOXICITY
OF DEHP HAS BEEN QUESTIONED, ESPECIALLY SINCE THE NATIONAL CANCER
INSTITUTE (NCI) REPORTED IN 1980 THAT VERY HIGH LEVELS OF THE
PLASTICIZER CAUSED LIVER TUMO RS IN MICE AND RATS OF BOTH SEXES IN
A LIFETIME FEEDING STUDY. EXTENSIVE TOXICOLOGICAL STUDIES ON DEHP
HAVE BEEN REVIEWED AND REPORTED TO THE CONSUMER SAFETY COMMISSION
