The chemicals found in polyethylenes are toxic and can damage human health.

The toxins can also cause cancer and birth defects.

Polyethylenims are made from polypropylene, a material that can withstand high temperatures, low pressure and high temperatures.

They’re also used in plastic bottles, and polyethylens are used to make food and other items.

“They’re incredibly toxic and they can damage people’s health in the long run,” said Dr. Mary L. DeBenedictis, the director of the Environmental Health Institute at the Johns Hopkins University School of Public Health.

“In some instances, they can even be carcinogenic.”

DeBensontis is the author of Toxic Substances in Household and Household Products: The Health Consequences of Environmental Contamination.

She said some of the toxins found in a plastic bottle could be harmful for human health because of the chemicals in the bottle.

“You can have a polyethylenedimide bottle and you have a plasticizer, you have another polyethylendimide,” DeBenistis said.

“So the end result of that is you’re using a mixture of chemicals that are not appropriate for human consumption.”

Plastic bottles and polystyrene polystyrols are not the only ones that could contain toxic chemicals.

De Bensontes said polyethylenic polyethylbenzene (PETB) and polymethylene (PMMA) are also found in plastics.

Those two are also used to form polystyrexene, which is used in a lot of consumer products and household products.

“These are all chemicals that you can find in household products,” De Benedictes said.

PETB is used to build, shape and paint plastic, but PMMA is used as a flame retardant.

She added that if polyethyleningyl ether (PEGE) was used to create plastic, it would be toxic because it contains a mixture called polyethyl ether monoxide.

That can cause liver damage, kidney damage and kidney failure, she said.

It’s not clear how often polyethylethylene polystyric acid (PEP) is used on plastics.

But DeBentis said it could be.

“There are many types of plastics, polystyres, polyethyleners and polyesters that have been found to be toxic,” she said, adding that it could affect health when used in these types of products.

For example, if plastic bottles and cans contain PEP, they could cause respiratory problems for the people in the home.

And because the chemicals can affect the nervous system, the use of the product could cause an allergic reaction, she added.

A study conducted by the American Academy of Pediatrics and published in the Journal of the American Medical Association found that PEP has been linked to a number of serious health problems, including cancer, heart disease, diabetes and lung disease.

De Boer said the chemicals found on plastics are often used in manufacturing.

“It’s a common way that the industrial processes are done,” she added, noting that polyethyles are used in many different products including plastic, vinyl, paper, and vinyl tubing.

DeBoer said there’s a lot more research that needs to be done to better understand the health effects of plastics.

“I think it’s very important that we know how to do the right thing when we’re manufacturing products,” she told CBS News.

“We can do a better job of using the right kind of chemicals to make the product and the right chemicals for the end consumer, so that they’re not exposed to harmful chemicals.”

The study also found that the levels of the most toxic chemicals are found in the environment.

DeMentis told CBS that the study does not consider the impact of the plastics that are being used.

“That’s why we need to understand the chemicals that actually are in the products we’re using,” she explained.

“What is the health impact of that?

And what’s the impact to our environment?

And we need those answers.”
