for this newspaper China daily features a latest test results show that plastic bottles of drinking water can make the human body is a controversial sex offset (that is, not men and not women) of chemical substance content raised more than two-thirds.

many plastic food and beverage containers, cans, as well as a transparent feeding-bottle containing a general chemical composition of Bisphenol a (BPA), the expert expressed concern about the effect it may have on human health, and the material has been officially classified as a toxic substance in some countries.

 

from the Harvard School of public health researchers surveyed 77 students, first of all, these respondents to wash for a week, during that period, without exposure to BPA as far . as possible, they can only have a stainless steel bottle of iced beverages. Researchers gave respondents two PC after plastic bottle, and asked them to in the next week, only used this water bottle drink iced beverages.

previous research has confirmed that high intake of BPA and birth defects, developmental issues, as well as linked to higher risk of heart disease and diabetes. Particularly worrying is that heating plastic bottles will cause even greater harm. For example when parents use a plastic bottle to the baby when you feed the hot milk, some potentially dangerous chemical substances into liquid in the bottle.

most adults carry BPA in the body, but for the harmfulness of the substances, the expert’s views were divided. According to the European food safety authority, the body will automatically translate into less harmful substances of the chemical substance.

previous research confirmed that BPA from PC plastic bottles into the liquid, but were published in the United States this research report in the journal environmental health perspectives has confirmed for the first time (after using PC plastic bottles of drinking water) of BPA concentration in human urine increases the corresponding content.

zhenni·kaweier Harvard University researchers said previous research has confirmed that BPA health side-effects, and this research has filled the blank of this inference–that is, PC plastic bottles are people high BPA levels in the body of the culprit.

 

using plastic water bottles to drink cold water only for a week, content of BPA in the urine of more than two-thirds. Heating plastic bottles, such as warm milk, the substance of the content can be quite high. BPA may disrupt the gland hormone secretion, infants are sensitive to this. Canada last year to ban the production of PC when plastic bottles with BPA. –Michelle
