Plastic foam boxes of vegetables
Eating plastic foam boxes grown vegetables will not cause cancer? To this end, the reporter interviewed Chemistry and Chemical Engineering Linyi University organic chemistry of Professor Peng Anshun. Peng Anshun explained that at present, the residents used to grow vegetables in plastic foam boxes main chemical ingredient is polystyrene. Polystyrene, its chemical structure, essentially non-toxic, can be used in food packaging, and its chemical properties are relatively stable and difficult to break down the water-soluble substances.
In addition, at high temperatures, the polystyrene monomer will decompose into polystyrene, polystyrene monomer does not dissolve in water. Meanwhile, polystyrene boiling point is very low, which means, polystyrene Polystyrene is decomposed into a monomer, insoluble in water, in the volatile atmosphere. Plants can absorb moisture in the soil, minerals and other ionic components, like, a large number of long-chain component benzene, basically not absorbed by crops. Therefore, cancer and plastic foam boxes to grow vegetables without necessarily linked.
In addition, also reminded the public that, for some unknown before its use of scrap foam box, while vegetables it is best not to use. Because some of the waste may be contaminated foam box harmful ingredients, vegetables definitely unhealthy use of such foam box.
