Recently, the research team led by Shi Huahong of East China Normal University also found that the salt obtained from salt lakes, salt wells and salt mines has a low content of plastic particles, but there are also 15 to 800 tablets per pound of salt. Sea salt is the most polluted by plastics, with more than 1,200 plastic particles per pound (1 pound or 0.45 kg) of sea salt.
Sea salt is heavily polluted. There are more than 1,200 plastic particles per pound.
A previous report from the Scientific American monthly website said that researchers analyzed the common salt of 15 brands purchased from supermarkets across China. They found poly-p-benzene for the production of ordinary plastic water bottles in salt granules. Ethylene glycol dicarboxylate, as well as polyethylene, cellophane and many other plastics.
Among them, sea salt is the most polluted by plastics. The researchers measured more than 1,200 plastic particles per pound (1 pound or 0.45 kg) of sea salt.
Plastic particles
The research team led by Shi Huahong of East China Normal University also found that the salt obtained from salt lakes, salt wells and salt mines, although low in plastic particles, is also between 15 and 800 per pound of salt. Shi Huahong and colleagues believe that plastic particles are derived from a large number of plastic pollutants floating in the marine environment where sea salt is obtained.
If a person's intake of sea salt reaches the maximum recommended by the World Health Organization, then this person will consume about 1,000 plastic particles per year. Despite this, it is still lower than the plastic particles that Europeans eat from shellfish. According to a report released last year, it is estimated that the average number of plastic particles in the shellfish consumed by Europeans per person per year is 11,000.
Plastics have become such a ubiquitous contaminant. This year, at the annual meeting of the American Association for the Advancement of Science in San Jose, the United States and Australia announced the first scientific assessment of the problem of plastic waste at sea. The world’s annual plastic waste into the ocean reached 8 million tons, among the 20 largest sources of plastic waste in the world. The top 19 are low- and middle-income countries, and the 20th is the United States. The most serious problem is the Asian countries. Among them, waste products from China accounted for 28% of all waste products, and Indonesia accounted for 10% of the total.
Indonesian marine pollution
The total amount of plastic waste flowing into the ocean is growing rapidly, and the speed is catching up with global plastic production. Although many of us live far from the ocean, we have become the biggest murderer of marine pollution.
Many marine organisms die after eating plastic waste, and many plastic particles are found in their stomachs.
Plastic waste not only affects the ecological environment of the coast and beach, but also threatens the life of marine life. It also causes great harm to human beings at the top of the food chain.
For the ocean, for ourselves, start with a beverage bottle and properly classify the plastic waste into a safe recycling channel.
