A new study says glazing can actually be more damaging than originally thought.
The findings are a result of an investigation by a team of scientists led by a former University of California at Berkeley professor who studied glazing research from the 1970s.
The researchers say the study is a clear reminder of the need to be cautious about glazing and what to do with it.
The team analyzed glazing studies that took place from 1973 to 1998 and found that glazing used on houses was actually more likely to contain asbestos, lead, and other hazardous materials than it was thought.
They found that the glazing was more likely than it would have been to contain the dangerous elements, like lead and asbestos, in the form of paint.
That suggests that the researchers were more correct than they initially thought about how much of these hazardous materials were actually present in glazing, said lead researcher Eric Wertheim, an assistant professor of engineering at the University of Utah.
But the researchers didn’t get their data right and didn’t account for the fact that the material they were studying was actually used in homes, he said.
They didn’t know whether the paint used in a glazed home was actually the same material used in other homes, for example, or whether glazing could contain asbestos.
“We wanted to know how much glazing is a risk and how much is a benefit, and that’s what this study was all about,” Wertheimer said.
This new research also found that while the research had been done before, there was no data on how much paint was actually in a house.
The study found that a paint glaze with asbestos in the paint contained an estimated 2,500 times more asbestos than a paint that was free of asbestos.
The researchers also found the paint glazed with asbestos contained up to 20 times more lead than a free glazed paint.
The new study found the lead levels in glazed glazed paints were up to 300 times higher than those found in free glazing paints.
Lead paint was not the only hazardous material in paint used by homes in the study.
The authors found that paint was also found to contain polycyclic aromatic hydrocarbons, or PAHs, a chemical that is known to cause cancer.
Lead is a toxic chemical that can damage the nervous system and cause hearing loss.
PAH’s also known to harm the eyes and kidneys.
The authors of the study also found evidence that paint used on homes contained lead and polycyclics.
The scientists used paint samples to determine if paint was free or glazed.
They determined that glazed products contained lead at levels similar to that of free glazes, and they found that free glaze paint was up to 15 times more hazardous than free glazier paint.
While lead paint was found in up to 75 percent of free and glazed house paints, free glasing paints contained less lead than free painting.
The lead levels of free paint were higher than that of glazing paint at levels higher than the Environmental Protection Agency standard of 25 parts per million.
The paint glazing also contained up, the authors of that study noted.
They calculated that free paint glazes were up more than 40 times higher in lead and PAH than free and dry glazing.
“This study is an important reminder that glazings that have been used for years, decades, decades are not always free,” said Werthels co-author David Mazzucchelli, a professor of civil and environmental engineering at UC Berkeley.
“And the paint should be free of lead and other PAH-contaminated paints.”
The researchers said the research was the first to provide data on glazing that wasn’t based on traditional paint analysis.
They also looked at paint samples from two houses and found more than 80 percent of the paint samples contained lead.
They also found a high percentage of paint was glazed by dry glaziers, not free glakers.
Wertheim said the results were not surprising.
“What’s surprising is that in the house studies, we found paint glazers and dry-glazers, and both were significantly higher in the lead,” he said, adding that they also found paint was more hazardous to the eyes than free paint.
But this study did not provide a definitive answer as to whether glazes are more hazardous because of paint, Wertheys co-authors said.
“There are many ways to estimate the health effects of paint on human health,” said Mazzuchelli.
“But we are interested in understanding whether paint is more hazardous in a free-glazing environment.”
The study will be published in the journal Proceedings of the National Academy of Sciences on Thursday.
