Are the darker the plastic bag, the more poisonous it is?

It has been nearly half a year since the "Plastic Restriction Order" was implemented in June this year. The reporter recently visited many areas in Guangzhou and found that the "Plastic Restriction Order" was like an empty letter in the farmers' markets where plastic bags are used the most. A rough estimate puts the number of ultra-thin plastic bags used in hundreds of farmers' markets in Guangzhou at hundreds of thousands every day.

Industry insiders and law enforcement officials said that most of the colorful ultra-thin plastic bags provided free by farmers' market vendors contain harmful substances and are not suitable for holding food. Citizens should think twice about taking free bags.

More than 90% of shoppers in supermarkets prepare "bags" and plastic bags are widely used in food markets.

The "plastic restriction order" has been implemented for nearly half a year, and it has obvious results in large shopping malls and supermarkets. At Jusco Supermarket, more than 95% of shoppers bring their own shopping bags. Even if they buy bags, most people choose reusable reusable bags. In the Shengjia Supermarket on Binjiang East Road, most of the customers are nearby residents. More than half of them bring their own shopping bags. Many people choose to take them home with their bare hands, and about 10% of them buy shopping bags.

But in the meat and vegetable market, where the largest number of plastic bags are used, the "plastic restriction order" is almost like a dead letter. On Sunday morning, the reporter saw at the Xinfenghuang Meat and Vegetable Market near Sun Yat-sen University that the hands of passing citizens were filled with colorful plastic bags, including red, yellow, orange, blue, and black. Almost all of them were super plastic bags. Thin bags, very few citizens bring their own reusable bags. The reporter made a rough calculation at the market exit and found that within five minutes, the number of plastic bags left by citizens was about 100. The reporter then walked around the market and found that none of the hundreds of stalls sold environmentally friendly plastic bags for a fee, and all provided ultra-thin bags for free.

Aunt Wang bought five dishes, namely two pieces of pork, one crucian carp, two eggplants, a bunch of cabbage sum, and a bag of garlic, but she was carrying seven plastic bags in her hand. It turned out that " The "generous" pork guy gave her an extra bag of pork, and the eggplant stall ran out of plastic rope, so the boss tied two blue ultra-thin plastic bags together to use as rope. The reporter walked along the market and found that none of the hundreds of stalls sold environmentally friendly plastic bags for a fee. All of them provided ultra-thin plastic bags for free, but the original price of the paid bags was still posted on the stalls.

The reporter also went to farmers markets such as Longjin Road and Changshou Road in Liwan District, Yankou and Changgang Road in Haizhu District, Haoxian Road and Dongchuan New Market in Yuexiu District. In addition to Dongchuan New Market Except for the relatively good implementation of the "plastic restriction order" in China, other markets are basically dominated by ultra-thin plastic bags. Even the high-priced "local pork" sold for more than 20 yuan per pound comes with ultra-thin bags for free.

If you are in a hurry to buy groceries and “have no time,” the environmentally friendly wholesale market sells ultra-thin bags generously

Why do most citizens bring their own shopping bags when shopping in supermarkets and shopping malls, but they have to do it every day? What if you don’t have this habit of going to the vegetable market? The trend of market stall owners giving away free bags is certainly one reason, but citizens themselves are also responsible. Zheng Yun, a white-collar worker, has a certain representative view: Shopping in shopping malls and supermarkets is "shopping", and it is basically planned. In addition, knowing that there is a fee, she usually brings her own shopping bags; while going to the market is a task, and she rushes after get off work. Don’t worry about bringing reusable bags wherever you go. Fish and meat are also bloody. Most people won’t object to the free bags provided by vendors. This habit is not easy to change.

In areas such as Tiancheng Road and Yide Road, where plastic bag wholesale stalls are concentrated in Guangzhou, ultra-thin plastic bags, which had been retired for a while after the plastic restriction order, are now openly sold in shops. The reporter visited 15 plastic bag wholesale stores of different sizes yesterday, and 6 of them made it clear that they did not sell ultra-thin bags, while all others were sold. Among them, the Wenjue Wholesale Department on Yide Road is larger in scale. Bundles of ultra-thin plastic bags are sold at the door with clearly marked prices. In the alleys of Xinqiao City on Tiancheng Road, several small shops sell ultra-thin bags of various specifications. The prices for black, red, orange and other colored bags are the same. A bundle of 100 bags ranges from 1.5 yuan to 3 yuan depending on the specification. The price ranges from 0.00 yuan to 0.5 yuan, and the white bags are 0.5 cents more expensive, and the transparent ones are slightly more expensive.

Colored plastic bags often contain powder residue. The darker the bag, the more dirt particles are covered up

“Both white and transparent bags can be used to hold food.” The boss picked up a bag The transparent bag with a score of 3.5 points emphasizes that "it can contain hot and spicy cooked food." The reporter immediately asked if colorful ones could not be used to hold food. "It depends on how you use them. It's a matter of opinion. You can tell by smelling and touching them." Picking up the colored bags, you can find some powder residue, especially the black plastic bags, which have a strong smell.

Yesterday afternoon, at the Haoxian Road market, the reporter saw two citizens buying river shrimp and the stall owner arguing about plastic bags. Ms. Liu, who is in her 50s, complained that the black plastic bags provided by the stall owner were "poisonous" and she specially prepared her own fresh-keeping bags for shrimps. When another aunt who bought shrimps saw this, she also said that the plastic bags smelled bad and asked the stall owner to change to another bag. , and the boss said that the free bags should be strong. Ms. Liu said, "I also bought shrimps here a few days ago, but on the way home, I could smell the smell from the black bags of shrimps on the bus. I was so scared that I had to soak them many times before I dared to eat them."

The reporter interviewed Rao Jianbing, head of the business section of the Baiyun District Quality Supervision Bureau. He said that standard plastic bags for food are made of polyethylene and are non-toxic, while some are made of polyvinyl chloride. Plastic bags are poisonous and must not be used to hold food. The ultra-thin colored plastic bags used in farmers' markets are often made from recycled waste plastics. The colorants used to cover up defects contain toxic substances. If used to package food, the toxic substances will penetrate into the food through the oil in the food. The vegetables, meat and seafood sold in farmers' markets are food raw materials. If they are packaged for a long time, harmful substances will also penetrate and cause harm to the human body.

We should be more vigilant about black plastic bags. Lu Zhiming, who is engaged in plastic processing, said that most black plastic bags are processed using waste recycled particles of poor quality, and a large amount of dark pigments are added to cover up these recycled materials. The particles are obtained by crushing and granulating waste packaging films, so it can be said that their origin is unknown. If the raw materials have been filled with toxic and harmful substances such as chemical fertilizers and pesticides, it is impossible to remove them by simple washing, so the safest way is to use them as "garbage bags".

It is understood that in order to ensure the safety of plastic bags for food, the quality supervision department controls at the source. Only companies that have obtained the production qualification of plastic packaging bags for food can produce food bags, and standardized food bags The bag should be marked with the "QS" logo. The ultra-thin colored bags used in farmers' markets definitely do not meet the standards for containing food. Citizens should not let the penny drop.

It is not difficult to "guide" the market in place and abandon "plastic" when buying vegetables

In the model market Dongchuan New Street, the model here is closer to a supermarket, and meat and fish are basically They are all packaged in free tear-tear bags, and vegetables are packaged with water plants or nylon ropes. More than 80% of shopping residents bring their own large reusable bags to hold meat and vegetables. Aunt Liang, who lives nearby, said that since the implementation of the plastic restriction order, there have been no free ultra-thin plastic bags here. “I didn’t get used to it at first, but after more than half a month, I got used to bringing my own bags.” Every time she comes to buy groceries, she brings a large reusable bag and a few fresh-keeping bags to cope with it. Aunt Liang also took out a fish shred bag that was very popular in the past and said it was very useful for carrying vegetables.

The reporter interviewed several citizens at Dongchuan Market. They said that environmental protection is not that difficult. If the market management is strict, habits will naturally be formed.
