Tan Dunzi, a clinical toxicology nurse of Linkou Changgeng, said that the concept of environmental protection and love for the earth is prevalent, and many people have begun to bring their own tableware. In fact, this behavior is not only altruistic but also self-serving. As for the plastic straw commonly used in drinks, it may face two major risks, plasticizer and heavy metal.

Yan Zonghai, director of clinical toxicology Department of Linkou Changgeng, said that if plastic pipettes were made of polyvinyl chloride (PVC), there might be a risk of release of plasticizers when exposed to high temperature. Tan Dunzi added that oily drinks such as dairy products, or acidic drinks such as fruit juice and cola, are also more likely to dissolve.

As for heavy metals, foreign inspections have found that some pigments of color pipettes originate from heavy metals such as lead or cadmium. Tan Dunzi suggests that if plastic pipettes are really to be used, it is better to use simple colors such as white or transparent.

Tan Dunzi said that plasticizers and heavy metals are not acute toxicity, but drink one or two cups a day, the long-term chronic cumulative impact should not be underestimated, especially some people like to bite pipettes, pipettes are damaged, these substances exposure risk is higher, it is recommended to own stainless steel or glass pipettes, more assured.

Some people worry that stainless steel straws can't be used in acidic drinks? Tan Dunzi said that as long as 304 stainless steel, acid and alkali resistance effect is absolutely no problem. In terms of self-contained pipettes, it is common and worrying that some people will think that pipettes are for their own use and do not wash them. It is afraid that this will continue to breed bacteria. People with poor immunity may cause infection problems. It is suggested that they should be washed every day to ensure hygiene. 57347
