On December 1, sports equipment such as rackets and skipping ropes commonly used by primary and secondary school students were exposed by CCTV News' "Weekly Quality Report" column. The plasticizer content of some samples exceeded the reference standard limit by more than 200 times. Let’s take a look at

More than a quarter of the tested samples

The plasticizer content exceeds the reference standard

Experts from the Fujian Provincial Quality Inspection Institute and the Ningbo Municipal Quality Inspection Institute are jointly conducting product quality and safety risk monitoring on the three types of products for the first time. These three types of products are balls, rackets and skipping ropes, which are currently used very frequently by primary and secondary school students.

What the inspectors want to know is whether the long-term contact between the skin and sports equipment will cause health risks when students are playing ball with rackets and skipping ropes with rope handles. In order to make the data as comprehensive and objective as possible, this risk monitoring sampled a total of 112 batches of samples , covering high, medium and low price ranges. The sampling channels involved offline large supermarkets, wholesale markets, sporting goods stores and retail stores. and major online e-commerce platforms.

At the same time, the reporter also conducted further investigation on the consumption and use of students' sporting goods. At present, my country is already the largest producer of sporting goods in the world, and most student sporting goods manufacturers are concentrated in Zhejiang, Guangdong, Fujian, and Jiangsu.

The reporter at the testing center saw such a set of risk monitoring data. Among the 112 batches of student sporting goods collected, 30 batches of products did not meet the reference standard requirements, with a non-compliance rate of 26.8%. The non-compliance rate of racket products is the highest, with a non-compliance rate of 60.6%, and the non-compliance item is plasticizer; followed by skipping rope, with a non-compliance rate of 17.5%, and the non-compliance item is mainly plasticizer; the non-compliance rate of ball products is 7.8%, it is still a plasticizer that does not meet the project.

That is to say, more than a quarter of the products in the samples have plasticizer content exceeding the reference standard, and the plasticizer content of some samples exceeds the reference standard limit by more than 200 times.

A large number of experiments have shown that long-term excessive exposure to plasticizers will interfere with human endocrine and affect adolescent reproductive health and growth and development.

Long-term intake of plasticizers

will affect the growth and development of children

What kind of substance is plasticizer?

Zhu Yi, associate professor at the School of Food Science and Nutritional Engineering, China Agricultural University: These are plasticizers, thick and oily.

What are the effects of excessive phthalate plasticizers on the human body, especially on teenagers? Experts told reporters that some studies have found that children's developmental abnormalities are related to the content of phthalates in the body.

Wang Yongwei, director of the Occupational Hazard Evaluation Department of West China School of Public Health, Sichuan University: Research shows that long-term plasticizer intake will have an estrogen-like effect on boys, which will have some impact on his growth and development. For girls, Some phenomena such as premature maturity may also occur.

Experts told reporters that plasticizers, also known as plasticizers, have been widely used around the world for nearly a hundred years, and eighty of them are phthalate plasticizers because they can increase plastic Its flexibility and stretchability are widely used in plastic products. The reason why this risk monitoring found that plasticizers in some skipping rope, racket, and ball samples exceeded the reference standard requirements is because they were also used in the production process.

Senior Engineer, Fujian Provincial Quality Inspection Institute Zhou Xiuhua: The purpose of wrapping the hand glue on the racket is to cushion and absorb shock during exercise. Some manufacturers increase the flexibility and elasticity of the hand glue so that the hand glue can be better wrapped around the racket handle. may be An excessive amount of plasticizer was added during the production process.

The reporter noted that current research has confirmed that phthalate plasticizers can enter the human body through oral ingestion, respiratory inhalation and skin penetration., and are considered to be the most produced by humans themselves. One of the environmental estrogens, it has been successively listed as a priority pollutant to be controlled by countries around the world.

During the investigation, the reporter found that primary and secondary school students In daily sports, the proportion of direct skin contact with rackets, skipping ropes and balls for more than 30 minutes is high. If sports products with phthalate plasticizers exceeding the reference standard are used for a long time, there will be health risks. .

The reporter consulted relevant information and learned that my country’s national standards have long made it clear that phthalate plasticizers are not food raw materials or food additives. In addition, relevant national standards for children's products such as children's clothing, shoes, toys, and children's furniture; and student supplies such as paints, crayons, and school bags also have clear limit requirements for phthalate plasticizers. The limit values are the same as The current EU standards are consistent.

However, the reporter found that the current standards have not set limits on phthalate plasticizers in student sports products such as balls and skipping ropes. It is understood that alternatives with excellent performance, non-toxic and safe properties have been found.

How to use student sporting goods more safely?

Be careful to select when buying and wash your hands after use

In response to the problems found in student sporting goods, The State Administration for Market Regulation stated that it will take follow-up disposal measures.

First-level researcher, Safety Assessment Division, Quality Supervision Department, State Administration for Market Regulation Wang Na: According to the results of this risk monitoring, the market supervision department has issued risk notification letters to relevant enterprises, requiring timely rectification measures, and timely organization and follow-up monitoring, and organized technical institutions to help enterprises find out the reasons in depth, and propose improvement measures and solutions. program to promote the improvement of industry quality levels.

Reporters searched and found that recently, the National Technical Committee for Standardization of Sporting Goods issued a draft national standard for "Skipping Rope", which specifically sets limits on the content of phthalate plasticizers in skipping ropes. The consultation draft is expected to be made public for comments in the near future. In response to the results of this risk monitoring, experts suggest that consumers should purchase regular brands through regular sales channels when purchasing products, and check whether the product logos are complete.

Deputy Director of the National Stationery and Educational Supplies Testing Center of Ningbo Quality Inspection Institute Tian Xuling: When buying products such as skipping rope rackets, it is best to touch the grip of the handle with your hands. Do not buy products with too soft materials. It is also not recommended to buy products with too bright colors and rich patterns. Because these products May contain excessive and excessive amounts of harmful chemicals. Parents should also supervise children and students to wash their hands after using rackets, skipping ropes, balls and other products.
