According to a recent press release issued by the German Research Association, the association sponsored a special study conducted by the University of Erlangen-Nürnberg in Germany that the reduction in the number of sperm in global men over the past few decades may be related to the use of chemicals that are widely used as softeners in light industry. Dicarboxylate related. This substance is widely found in cosmetics, children's toys, and food packaging. If its content is excessive, it will cause great harm to human health. So, what kind of material is it? What kind of harm will it cause to the human body?
According to experts from the Institute of Environmental Health Monitoring at the Chinese Academy of Preventive Medicine, phthalates are a class of chemicals that can act as a softening agent. It is commonly used in hundreds of applications such as toys, food packaging materials, medical blood bags and hoses, vinyl flooring and wallpapers, detergents, lubricants, and personal care products (such as nail polish, hair sprays, soaps, and shampoos) In the product.
An expert from the Department of Chemistry at Tsinghua University said that studies have shown that phthalates play a role similar to estrogens in humans and animals. They can interfere with endocrine, reduce semen volume and sperm count, reduce sperm motility, and sperm morphology. Serious testicular cancer is the "culprit" of male reproductive problems.
In cosmetics, nail polish has the highest phthalate content, and many cosmetic aroma components also contain it. Experts say that this substance in cosmetics will enter the body through the female's respiratory system and skin. If it is used excessively, it will increase the chance of women suffering from breast cancer, and it will also endanger the reproductive system of the baby boys that they will have in the future.
Experts have found that soft plastic toys and children's products containing phthalates may be put in children's imports. If they are left for a long time, the amount of phthalates released will exceed the safe level, which will endanger Children's liver and kidneys can also cause precocious puberty in children.
In order to reduce the harm of phthalates to the human body, it is usually necessary to pay attention not to foam instant noodles with foam containers. Do not use polyvinyl chloride (containing phthalates) plastic containers to heat foods in a microwave oven. The correct procedure is to move foods into heat-resistant glassware or ceramic vessels for heating.
