Concern: U.S. research says plastic bottles may cause cancer

U.S. government health agencies issued a preliminary report on the 15th saying that animal experiments showed that the chemical substance BPA contained in plastic bottles may cause canceration and other functional disorders.

BPA is widely used in the manufacture of baby bottles, discs, food containers and other plastic products. Some US lawmakers called on the government to re-examine the safety of BPA.

Plastic producers believe that
The report does not prove that BPA is harmful to the human body.

â–  Attitude change

The National Institute of Toxicology (NTP), affiliated with the National Institutes of Health, said that the results of animal experiments showed that BPA may cause canceration. The Planning Department expressed concern about this.

In the experiment, mice exposed to BPA developed signs of cancer such as breast cancer and prostate cancer. The Planning Office said that it is necessary to further study the safety of BPA.

Mike Shelby, director of the Toxicology Planning Department, said: "The results of the study are a warning, a signal that needs attention. We do not rule out that BPA may cause similar hazards to humans."

The Division of Toxicology uses a five-level warning system, from "serious attention" to "negligible." "Being concerned" is of medium concern.

The National Toxicology Planning Office rated the potential level of BPA warnings for fetuses, infants and children as “a little concern” and the potential harm to adults as “negligible”.

The Washington Post said that this report shows that the U.S. government has changed its attitude toward BPA security.

The U.S. Food and Drug Administration acknowledged last month that the Agency has disregarded the results of hundreds of government and academic institutions' research and only adopted two studies funded by plastics manufacturers to declare BPA safe.

â–  Concerned about the bottle

After the report was published, some researchers and lawmakers in the United States asked the Food and Drug Administration to reconsider the attitude toward BPA safety, because many baby products also contain BPA.

John Dingell, chairman of the US Senate Energy and Commerce Committee, said: "For the health of infants and children, I hope that the Food and Drug Administration will reconsider its attitude on the BPA issue." Henry A. Wake, chairman of the Senate Reform Committee Siman said: “The Office of Toxicology Planning has listened carefully to the opinions of scientific researchers. The report concerns public health and must be guaranteed to be free from errors.” Anila Jacobs, a member of the non-profit environmental working group, said: “Children are subjected to double Double hazard."

The Food and Drug Administration has not commented on this. The Food and Drug Administration said in November last year that there is no reason to prohibit or limit the use of BPA.

BPA is widely used in plastic manufacturing, and almost all Americans cannot avoid it. The Washington Post stated that 93% of Americans over the age of 6 can detect BPA in their urine.

This report caught the attention of the U.S. public. Bottles containing no BPA ingredients became hot items. BornFree, a manufacturer of such bottles, said that the company’s supply of bottles is in short supply. The CEO of the company, Gille Lamel, said: “Each time we publish a report on the safety of BPA, our inventory will be told in a few days...We produce 80,000 baby bottles every day, but we still have no stock.”

â–  Security disputes

The controversy over the safety of BPA has been a long time. U.S. plastics manufacturers believe that the new report does not prove that BPA is not safe for humans. There is no need to panic.

The American Chemical Society, which represents plastic manufacturers, said that the report proved that "BPA does not have a serious negative impact on humans." The Chemical Society supports the in-depth study of the safety of BPA.

The American Chemical Society publishes an article on its website saying: "Most scientific research clearly shows that BPA is safe. The BPA's statement on human health is completely groundless." The Washington Post stated that local governments such as California and New Jersey are working on the issue. Considering banning the use of BPA, Maine plans to require manufacturers to mark the products with BPA warnings.

The report said that the Canadian government may list BPA as "harmful substances".
