It is one of the most widely used chemical components in jewelry, which can be found in cemeteries, graves, and burial plots.
While the toxic effects of BPA on the human body are well known, it has not been studied enough to make a definitive statement about the long-term health effects of its use.
Now, a team of researchers at Cornell University has found that BPA is toxic in humans.
A study published this week in the journal Environmental Health Perspectives found that, of the more than 10,000 individuals studied, BPA exposure was found in more than 50 percent of participants.
That’s significantly higher than previously reported, the researchers found.
“The study shows that BPCS is a highly toxic substance and its levels are increasing at a rate consistent with that of other BPA exposures,” lead author and professor of environmental toxicology, Laura B. Stearns, said in a statement.
“This study demonstrates that BPS is also a highly harmful substance.”
The study was based on the National Health and Nutrition Examination Survey (NHANES), a nationally representative survey of Americans conducted in the 1960s and 1970s.
A total of 6,957 participants participated in the study.
The participants were aged between 25 and 59 years old, and the average age was 40.
The study found that nearly one-third of the people in the sample had BPA levels in the range of 5 parts per billion, which is roughly 1,000 times higher than the Environmental Protection Agency’s (EPA) maximum allowable level of 1 ppb.
That level of exposure is higher than what is allowed by the Occupational Safety and Health Administration (OSHA).
BPA can also be found naturally in many other foods and beverages, including food processors, baked goods, and toothpastes.
The amount of BPS found in the blood of the participants ranged from 1.3 parts per million to 8.2 parts per trillion.
The researchers said the levels of BPCs in the participants’ blood are likely due to the high concentrations of BPHs, which are also found naturally.
While BPA was not the main driver of the study’s findings, it was a key contributor to a significant increase in BPC levels.
BPCP is a compound found in BPA, which the researchers believe is responsible for the observed increase in blood levels.
The compound, BPCPs are highly reactive, and they have the potential to trigger cancer.
BPA’s health impacts have been studied before.
In 2015, a group of scientists led by Dr. David M. Johnson of the University of California, Berkeley, published a study that found that exposure to BPA in the workplace increased the risk of cancer.
The results were consistent with the earlier research and suggested that BPH levels in blood could be a marker for BPA use in the future.
The new study, which also involved the Cornell lab, was not able to directly measure the BPA level in participants’ urine or saliva, but they found that they had levels of the BPC compound that were nearly twice that of the EPA’s limit.
BPH can cause cancer, and BPA has been linked to breast cancer in humans as well.
Researchers have also linked BPA to heart disease.
The Cornell study looked at the levels in participants over a 12-month period and determined that the amount of the compound in their blood was nearly 20 times higher in people with high BPA than in people without BPA.
The team, however, said that they cannot say with certainty whether this is a direct result of BPD, a genetic disease, or simply because BPA may be the cause of the elevated BPC in the people who were exposed.
“Our results suggest that BPD and/or BPA are likely independent of BP, and that the BPD-associated increase in the BPH level is a consequence of BPP exposure,” the authors wrote.
“We hypothesize that the elevated blood BPS levels in these BPD subjects reflect BPA-induced damage to the endocrine system, possibly through alterations in hormonal signaling pathways, and may be an additional marker of BPM exposure.”
