What harm does plastic bag do to human beings?

what harm do plastic bags do to human beings? What are the hazards of plastic bags to the environment? At present, the annual output of plastics in China is 3 million tons, and the consumption is over 6 million tons. Plastics not only bring convenience to people's lives, but also bring irremediable troubles to the environment. People call the disaster brought by plastics to the environment "white pollution". Plastic bags are not only harmful to the human body, but also more harmful to the environment. What are the specific injuries?

What harm do plastic bags do to human beings? 1. Destroy immunity. Some plastic bags and paper lunch boxes will add some whitening agents and fluorescent powder, which are not only potentially carcinogenic, but also destroy human immunity.

2, causing blood system diseases. After being heated at high temperature, PVC contained in non-food plastic bags will easily produce harmful substances such as dioxins, causing diseases of liver and kidney, central nervous system and blood system.

3, carcinogenic. The composition of plastic bags for food is mostly polyethylene, which is not easy to decompose as long as it is below 11 degrees Celsius, so it is generally no problem when containing water-containing food with a temperature not exceeding 1 degrees Celsius. However, the temperature of fried food just out of the pot, such as fried dough sticks, far exceeds the tolerance temperature of food bags, which may lead to the production of harmful substances. Light people may be dizzy and nauseous, while heavy people may cause cancer.

4, lead to gallbladder, kidney calculi. Unqualified plastic bags mostly contain industrial calcium carbonate and paraffin. Calcium carbonate can cause constipation or gallbladder and kidney calculi; Paraffin wax can make people have diarrhea.

5, affect intelligence. If the heavy metals in plastic bags exceed the standard, it will affect the blood system and intellectual development.

The annual output of plastics in the world is 1 million tons. If the annual plastic waste is calculated by 15%, the annual plastic waste in the world is 15 million tons, and that in China is more than 1 million tons, accounting for 4% of the garbage. So a lot of discarded plastics are buried underground as garbage, which undoubtedly brings greater pressure to the arable land that is already lacking.

At present, many countries adopt incineration (thermal energy recycling) or reprocessing manufacturing (product recycling) to treat waste plastics. These two methods can recycle waste plastics and achieve the purpose of saving resources. However, because waste plastics will produce gases harmful to human body and pollute the environment when they are burned or reprocessed, it can be said that the treatment of waste plastics is still a headache in environmental protection work.

What harm do plastic bags do to the environment? Plastic bags do bring convenience to people's lives, but this temporary convenience brings long-term harm.

The recycling value of plastic bags is low. In the process of use, it is not only scattered in urban streets, tourist areas, water bodies, roads and railways, causing "visual pollution", but also has potential hazards. Plastic has a stable structure, is not easily degraded by natural microorganisms, and does not separate in the natural environment for a long time. This means that if the waste plastic garbage is not recycled, it will become pollutants in the environment, which will exist permanently and accumulate continuously, and will cause great harm to the environment.

first, it affects agricultural development. The accumulation of waste plastic products mixed in soil will affect the absorption of nutrients and water by crops, resulting in crop yield reduction.

secondly, it poses a threat to the survival of animals. Waste plastic products abandoned on land or in water are swallowed by animals as food, resulting in animal death. Last year, there were 2 herdsmen on the lakeside of Qinghai, and nearly 1, sheep died, resulting in an economic loss of more than 3, yuan. Sheep like to eat oily residues wrapped in plastic bags, but they often eat them together. Because the plastic they eat is difficult to digest in their stomachs for a long time, their stomachs are crowded and they can no longer eat, and finally they can only starve to death. Such things are common in zoos, pastoral areas, rural areas and oceans.

thirdly, waste plastics will not only occupy a lot of land with garbage landfill, but also the occupied land will not be restored for a long time, which will affect the sustainable use of land. Waste plastic products entering domestic garbage will not degrade for 2 years if they are buried.

Moreover, plastic bags are made of petroleum, which not only consumes a lot of resources, but also cannot be decomposed. Burying them underground will pollute the land and rivers.

in addition, plastic bags themselves will release harmful gases. Cooked food, in particular, often goes bad after being packed in plastic bags. Deteriorated food has a particularly prominent impact on children's healthy development.

it consumes a lot of energy. according to estimates, every ton of plastic bags in China needs 3 tons of oil, and the annual consumption of plastic bags in China can run at least 3 million ordinary cars for 5 years. Changing this situation, eliminating ultra-thin plastic bags is the general trend, benefiting the country and the people, and contributing to the future generations.

What are the harmful components of plastic bags? The plastic is a polymer compound which is polymerized by a large number of monomers with small molecules through valence bonds. It is made of polymer resin as the main raw material and plasticized by adding a proper amount of additives.

The high molecular compounds of synthetic plastics are polyvinyl chloride, polyethylene and polypropylene, and their small molecular monomers are vinyl chloride, ethylene and propylene respectively. In the process of polymerization of small molecules into macromolecules, some monomers that are not involved in polymerization or compounds that are not fully polymerized have neurotoxicity and cytotoxicity. For example, vinyl chloride monomer, after human contact, can cause hepatic angiosarcoma in severe cases.

Of course, some additives, such as plasticizers, stabilizers and colorants, added in the process of synthesizing plastics may also migrate to food during contact with food. Some plasticizers, such as phthalates, have the characteristics of estrogen; Some stabilizers that do not meet the requirements (see GB/T21661-28 for details), such as lead stearate, barium stearate and cadmium stearate, are harmful to human body.

Advantages and Disadvantages of Plastic Bags In our daily life, plastic bags do bring convenience to our lives, but this temporary convenience has brought long-term harm in the future.

Plastic bags are often seen in shops, vegetable markets and delicatessens, and with this plastic bag, people no longer have to worry about buying too many things to take. But what harm will plastic bags bring to us while bringing us convenience?

Plastic bags will not only affect the development of agriculture, but also do great harm to the land, which will change its pH and affect the absorption of nutrients and water by crops. Other plastic bags are thrown into some wasteland. If these plastic bags are recycled, processed and reused, there will be more magazines and additives, which will be more harmful to people's health.

Plastic bags not only do harm to human beings, but also pose a threat to the survival of animals. Sheep like to eat the parade residue wrapped in plastic bags, but they often eat the plastic bags together. Because the eaten plastic stays in their stomachs for a long time and is difficult to digest, these sheep's stomachs are crowded and they can't eat any more, and finally they can only starve to death.

Plastic bags are too harmful. Please refuse to use them for the sake of our living environment. [Detailed > > ]

If you don't like them, take one away. It's not too late to tidy them up when you come back. What a beautiful bag to save. See you later. Tie a knot in the plastic bag of garbage bag and pile it up. The most taboo of plastic bags for storing garbage bags is to throw them at will, which takes up too much space and is easy to salvage. So, first, pull the plastic bag into the shape of a rag and tie a knot. With the concentrated quality, the plastic bag will be better placed and taken. And I just make them look like rags, tie a knot and put them all in a small wastebasket. When you take it out, you can easily see the size and quality of the whole bag, so when you use it as a garbage bag in a big bucket, take a larger plastic bag with good quality and use it to hold small garbage, and take a small bag.

There are also plastic bags for express delivery and plastic bags for take-away. These plastic bags can really be reused. Plastic bags for clothes can be classified as beautiful and suitable for garbage, plastic bags for express delivery and take-out can be used as garbage bags in the room temporarily, plastic bags for food can be used as garbage bags before and after cooking in the kitchen temporarily, and so on. Reuse plastic bags, increase the utilization rate of existing plastic bags and reduce the utilization rate of new plastic bags, and Mother Earth will be healthier. Reduce the chances of obtaining plastic bags. When shopping, clothes bought by different stores can be put into the same bag if they are bought too much, so that merchants don't have to take another bag. When buying snacks, you can take one less bag if you can hold it. After shopping in the mall, take your shopping bag in advance, so you don't have to buy plastic bags from the mall. If you buy less things, you can also take a fresh-keeping bag directly from the shopping mall and just put all the goods in it. Both of these methods save money, labor and resources. Love life, love life and cherish the earth. Establish a correct view on the use of plastic bags. Plastic bags not only make our life simple, but also make our life more enjoyable. For example, when you buy something to support them, for example, when you buy sanitary napkins, you have a black bag to hide them afterwards, for example, when you eat snacks, you can keep your hands from getting dirty. So in general, plastic bags are a good thing. Making good use of them will certainly do a good job. Plastic bags should be saved, but they are also worth using well. Control the improper use of plastic bags. In fact, plastic bags should not be in direct contact with cooked food and hot food, which is not good for health and will release bad gases to the atmosphere. Don't use plastic bags to get food unless it's an emergency, which will harm your health and pollute the environment.
