US media: Chinese supermarkets sell salt and contain many kinds of plastic particles.
according to the recent report by "Scientific American", the Chinese people with sea salt flavour may have unwittingly eaten plastic pollution. Dye particles. Europeans, however, may eat more plastic particles from shellfish.
the report said that researchers bought 15 different brands of ordinary salt from supermarkets across China, and found polyethylene terephthalate, polyethylene, glassy paper, and a variety of other plastics from salt granules.
the highest level of plastic content is sea salt, and the researchers measured more than 1200 plastic particles in the sea salt of each pound (0.45 kilograms). The research team, led by Dr. Shi Huahong of East China Normal University, also found that the salt produced in Saline Lake, salt wells and salt mines, though relatively low in the content of plastic particles, is also around 15~800 grains per pound. The researchers believe that plastic pollute particles are derived from a large amount of plastic contaminants floating in the marine environment of sea salt, such as plastic water bottles thrown into the water, or cosmetics using plastic microbeads as washing milk for exfoliation.
at the same time, researchers also indicated that plastic particles may also enter other forms of salt, including processing, drying and packaging.
Mason (Sherri Mason) of the plastic pollution research at New York State University in California said that, given that manufacturers usually vaporized sea salt by evaporation from seawater, the process evaporates water, and all other substances are left, so in other places outside China, sea salt contains plastic particles. The situation may also be common.
plastic has become a ubiquitous pollutant, so I think it doesn't matter whether you find plastic particles in the sea salt in China or in the American supermarket shelves. " He said he would like to see some follow-up studies. As plastic pollution contains heavy metals and other worrying chemicals, it is advisable to minimize plastic access to the food chain.
, however, the previous research team also said that if a person's intake of Chinese salt reached the maximum of the WHO recommended intake, the person's annual intake of plastic particles was about 1000, which is still far below the European intake of shellfish. According to a report released last year, Europeans consume about 11 thousand plastic particles per year on average because of seawater pollution.
