What are the hazards of plastic products

by admin

plastic bags do bring me shit, but they do harm for a long time Plastic bags have a low collection value, except for scattered urban streets, tourist areas, water bodies Visual pollution on both sides of roads and railways has potential hazards. The stability of plastic structure is easy to be degraded by micro bacteria. From the environmental period, it means that waste plastic waste is charged. Environmental variable pollutants exist permanently and accumulate continuously. Environmental polar hazards affect agricultural development. Waste plastic products are mixed with soil and accumulate continuously, which affects the absorption of water by crops, resulting in the reduction of crop production. The second physical structure threatens to abandon waste plastics on land or water The products were swallowed as food, resulting in the death of nearly 1000 sheep in 20 herdsmen on the Bank of Qinghai Lake. The economic loss was about 30000 yuan. Sheep liked to eat plastic bags wrapped with oily residues, but they ate even plastic bags. Because it was difficult to digest the retained stomach in the plastic room, some sheep’s stomach was full, and then they could starve to death in food gardens, pastoral areas, rural areas It is common to see that the three wastes of marine plastics only occupy a large amount of soil with the landfill, and the recovery of the occupied soil will affect the sustainable utilization of the soil into the waste plastic products. The degraded soil in the landfill room 200 is extremely harmful, changing its pH will affect the absorption of water by crops, resulting in the reduction of agricultural production. As for the abandoned water or land plastic products, it will only affect the environment and cause death if swallowed, damaging the state balance?? Fourth, high temperature will detoxify toxic substances plastic products. The collection and reuse equipment of toxic substances is perfect, the process is simple, and the manufacturer may cooperate with the business license, resulting in the temperature of recycled plastic products reaching 6.5 ℃. If toxic substances are separated and penetrate into food, the liver, kidney White pollution mainly refers to the two negative effects of visual pollution and potential harm caused by the environment. Visual pollution refers to the damage to the city appearance and landscape caused by the random disposal of plastic waste in scattered cities The amount of rivers and lakes, the flying of polystyrene foamed plastic tableware or the hanging of ultra-thin plastic bags all reflect a strong potential crisis to the people with visual stimulation. It refers to that plastic waste enters the environment and is difficult to reduce and release environmental problems. Its harm mainly includes the following points: easy collection and utilization cost is high, utilization rate is low, businesses are profitable, and it is difficult to attract people to carry out white collection work due to low collection price Refractory white waste is easy to treat. At this stage, it is mainly treated for incineration and landfill. If it is burned, it will produce toxic smoke, pollute the gas and promote the formation of acid rain. As for landfill, it will be buried in its original state, which is absorbed and extremely harmful to the soil. Its pH will affect the absorption of water by crops, resulting in the reduction of agricultural production. As for abandoned water or land plastic products, it will only affect the environment and cause death and damage the state balance if swallowed High temperature will detoxify toxic substances plastic products. The collection and reuse equipment of toxic substances is perfect, the process is simple, and the manufacturer may have a business license, resulting in the temperature of recycled plastic products reaching 6.5 ℃. If toxic substances analyze and penetrate into food, they will cause harm to important parts of liver, kidney, reproductive system and pivot nerve. Answer: black and white_ Milk tea – take five levels one one one one one one: 0 2 potential crisis refers to that plastic waste enters the environment and is difficult to reduce and release environmental problems. Its harm mainly includes several points: easy collection and utilization cost is high, utilization rate is low, businesses are profitable, and due to low collection price, it is difficult to attract citizens to carry out white collection work, resulting in easy collection, difficult degradation, easy treatment of white waste. At this stage, it is mainly treated by incineration and landfill Its incineration will produce toxic smoke, pollute gas and promote acid rain. As for landfill, it will bury 100 in its original state, which is absorbed and extremely harmful to the soil. Its pH will affect the absorption of water by crops, resulting in agricultural production reduction. As for abandoned water or land plastic products, it will only affect the environment and lead to death and damage the state balance if swallowed. High temperature will detoxify toxic substances. Plastic products this toxic substances collection and reuse equipment If the process is perfect and simple, and the manufacturer is allowed to sign the business license, the temperature of the remanufactured plastic products will reach 6.5 ℃, and the toxic substances will separate out and penetrate into the food, which will lead to liver, kidney Experts have found that almost all plastic products contain plasticizers, which pose great potential hazards, and have caused a safety crisis of supermarket fresh-keeping film. Plasticizers (plastic bags and plastic products contain phthalate esters, adding seeds to increase plastic plasticity, flexibility and strength of plastic products) Now the problem is that people use plastic barrels of edible oil for three meals. Long ago, Guangzhou food safety information China released a news that Tongji research confirmed that the plasticizer in plastic barrels of edible oil is harmful to the body. The news said that Professor Li Shuguang’s research group of Tongji basic hospital had not collected the same brand of plastic barrels of bean salad oil, blending oil According to the determination of flower oil and bulk soybean oil sold in the market, it is found that almost all brands of plastic barreled edible oil contain the plasticizer dibutyl phthalate. It is inferred that the plasticizer in edible oil inspection mainly comes from the toxic effect of the plastic container. The plasticizer is more toxic to men. It is directly recognized that the plasticizer compounds have low toxicity, good physical and chemical characteristics and low fecal price, which almost restricts the production and use. At present, I have increased the use of plasticizers A comparative study conducted by Professor Li shows that the plasticizer for edible oil inspection mainly comes from the edible oil collected by its plastic container research group. It is found that the plasticizer content of plastic barreled edible oil of two brands is 2.9 mg /L 24 Yilu mg /L researcher recognized that due to the high content of plasticizer in the plastic container of this brand or the pollution of plasticizer in production and processing engineering, it was found that there was no significant correlation between the content of phthalate plasticizer and storage. The factors affecting the migration rate of plasticizer to edible oil were compared with those except storage room, storage temperature and plastic packaging materials? Plasticizer content off: the higher the storage temperature, the faster the migration rate; The higher the plasticizer content is, the more compatible the plasticizer content is with the edible oil stored in the kitchen. The higher the plasticizer content is, the more the plasticizer content is with the edible oil stored in the plastic barrel It means that the plasticizer with high cooking range can be inhaled into the lung with oil fume. The news said that the researchers found that the plasticizer has low Chinese sexual toxicity, and there is almost no Chine
se sexual toxicity in a short period of body intake, which means that it is safe. On the contrary, its chronic toxicity is harmful to foreign substances. The research results show that the plasticizer leads to reduced storage rate, weight loss, liver and kidney function Experts introduced that PVC products containing DOP (dioctyl phthalate) plasticizer are widely used in medical and related fields and are difficult to use. Its materials all replace latex gloves, plasma bag blood transfusion, infusion, respiratory appliances and children’s toys The proportion of PVC products for leather making (used as clothing, shoe material, handbag, sofa fabric, etc.) some developed countries have used plasticizers for some products, and their additives are strictly regulated or recommended accordingly. The main plasticizer for medical gloves and plasma bags is still DOP, which makes the plasticizer pollute almost all kinds of raw materials used in chemical industry. With the passage of time, plastic products slowly overflow into the air, soil Water sources and even food have a wide range of use, and the impact of polluted areas is more serious than pesticides, DDT and Professor Li Shuguang. Professor Li Shuguang pointed out that at present, there is a trend of less awareness of the danger of planting seeds, and the Family Customs Department will give effective prevention and strong control to our phenomenon With the development of plasticizers and the increase of their use scope, more and more attention has been paid to their safety. Governments have begun to realize the potential threat to the health of plasticizers. Denmark prohibits the use of phthalate plasticizers in children’s toy care products. Children like to put toys into the mouth. Plasticizers are harmful to children’s health; Switzerland prohibits the use of DOP in children’s toys. Although the types of plasticizers are the same, it basically follows two principles: it limits the use of plastic plasticizers; Second, the principle of limiting the allowable amount of migration to food is the combination of the two principles mentioned by Jiamei, Germany, Britain, the Netherlands, Italy and Spain. It is reported that I have formulated the hygienic standard for the use of additives for food containers and packaging materials (gb9 Luba 5-9 IV). The varieties of additives for food containers and packaging materials The application scope and dosage are specified, and its DBP (dibutyl phthalate) The allowable use of DOP varies from 3.5% to 50%, and the allowable content of food has not been formulated. Experts suggest that the food industry should stress to advocate reducing the use of plastic packaging containers, especially to avoid direct contact between plastic products and various foods, prevent plasticizer food pollution and increase investment in scientific research, research on the toxicity of plasticizer and related prospective epidemiological investigation on the same health Based on the analysis of plasticizers with high toxicity at the same level, develop higher quality and safer alternative products, and study relevant dry prevention and treatment measures
