Germany Research Association recently issued the press release said that the Association funded Germany well Lange · Nuremberg University special studies have shown that global decline in sperm counts in men may be the past few decades and light industrial chemicals widely used as softeners in phthalate ester-related. This substance is widespread in cosmetics, toys, food packaging, if excessive, may cause a lot of harm to human health. So, what exactly it is a substance which caused harm to the human body? We interview experts on this issue.
According to researcher by the Chinese Academy of preventive medicine and environmental health monitoring Qu Jian Qiao introduction, phthalate esters are a class of chemicals can be softened. It is widely used in toys, food packaging, medical blood bags and rubber tube, vinyl flooring and wallpaper, cleaning agents, lubricants, personal care products, such as nail polish, hair spray, in hundreds of products such as SOAP and shampoo.
Department of chemistry, Tsinghua University Professor Cheng changmei said, studies have shown that, phthalate esters in human and animal body plays a similar role of estradiol may interfere with the endocrine, men\'s semen volume and sperm count decrease in sperm motility low ability, abnormal sperm morphology, serious causes of testicular cancer, was the cause of male reproductive problems \"blame\".
In cosmetics, Nail Polish had the highest content of phthalic acid esters, aromatic component also contains the substance of many cosmetics. Cheng changmei says of this substance in cosmetics through the respiratory system and skin of women into the body, if excessive use, increases the chances of women suffering from breast cancer, but also jeopardizing their future fertility of the male reproductive system.
From the perspective of the present situation, people of phthalic acid esters in children\'s products the most attention. Prof Cheng said that in 1999 of the European Union will make a formal decision, within the EU Member States, the use of children under 3 years old toys in contact with the mouth (such as baby pacifier), and other content of phthalic acid esters in children\'s products are strictly limited. Experts found that contains phthalic acid ester of soft plastic toys and children\'s products is likely to be child-and-drop in imports, if the place of time long enough, can cause dissolution of phthalic acid esters than safety standards, will jeopardize the child\'s liver and kidneys, can also cause children sexual precocity.
Prof Cheng told reporters that at present, China has no clear provisions on the content of the material also, ordinary consumers difficult to see the content of the substance from the marking of goods, the relevant departments should strengthen standardized management in this area. In order to reduce the harm of phthalic acid esters on the human body, usually to note it is best not to use styrofoam containers foam noodle. Do not use PVC (contains phthalic acid ester composition) in plastic containers in the microwave heating of food, the correct approach is to move the food to heat-resistant glass or ceramic containers for heating.
