White pollution survey report

I. Survey plan

Plastic bags, the items we touch every day, seem to have become close partners in our lives. Red, black, blue, purple, colorful plastic bags add a lot of color to our lives, but also bring a lot of convenience to our lives, but do you know that these plastic bags may be with you? Intimate contact erodes our health step by step? At the same time, these white rubbish will gradually destroy our homes, but if we really lack them in life, it will bring us a lot of inconvenience. So many citizens have sent out such feelings: plastic bags, less you are inconvenient, you have trouble.

In order to understand the plastic bag and the "partner" that we are in close contact with every day, we have conducted a social survey to truly understand our partner by checking the information and on-the-spot observation.

Second, the investigation process

From January 27th to 30th, we went to the vegetable wholesale market, the main street and other places. The survey found that the plastic bags of various colors are very large, but the hawkers and shop owners in the market will It is unclear about the impact on health.

As early as January 27th, we saw that there were red or purple plastic bags on the food stalls, and red plastic bags were hung on the meat store. Even the vegetable hawkers packed the bundles of vegetables. Sack-sized plastic bag. At a wholesale point of garlic, we saw bundles of garlic in a slightly purple plastic bag, and most of them were tied with a rope, so we asked the hawker: "The bundles are so tight, these plastic bags are harmful. Didn't the material invade into the garlic?" Who knows the hawker tells us: "Why is it possible? We have always been packed like this, and we haven't seen anyone who has problems with this plastic bag." And on the south side of the market There are many vendors selling various plastic bags while selling spices.

On the afternoon of January 27th, we found here that the plastic bags used by the hawkers here are much thicker than the average plastic bags, both black and red. We asked a chef who sells fish: "Does these plastic bags affect health?" He seems to be a bit puzzled when he hears us: "Is it healthy? This fish is not eaten raw, how can it affect health? Besides, no need This plastic bag, do you let us use it? This plastic bag is both strong and waterproof, and it is just right to sell fish."

Early January 30 We found in some restaurants that the use of plastic bags is quite common. In order to save the trouble of washing dishes, restaurants usually put a plastic bag on the bowl. These plastic bags are generally white and are divided into two types, transparent and opaque. The porridge, dumpling skin, etc. will enter the customer's stomach after intimate contact with the plastic bag without exception. I asked a boss in a breakfast shop to use a plastic bag to fill the porridge. The boss smiled and said: "There is no problem, we are all from the formal channels." When we ask what these formal channels are When he told me that there were people selling outside the store, we bought some, and almost everyone else was using it. In addition, the boss also told me that most of these plastic bags came in from the wholesale market, and the chemical composition of these bags at high temperatures did not harm the human body. The boss also said that it was unclear.

After two days of actual investigation, we found that people know little about the harm of plastic bags to the human body, showing a kind of indifference, so how much harm does the plastic bag pose to the human body?

At present, the plastic bags we often use are mainly made of polyethylene, polypropylene and polyvinyl chloride. Among them, polyethylene and polypropylene have no toxic effects on the human body. Plastic bags made of polyvinyl chloride, because they contain chlorine, produce toxins that cannot be used to hold food.

In addition, we also found a method for identifying polyvinyl chloride and polyethylene. Polyvinyl chloride is on fire and extinguished from fire. Polyethylene and polypropylene burn with a yellow flame and can continue to burn away from fire. So we conducted a test on the plastic bags that we often use according to the method. We found that the red, white, yellow, blue, red and purple plastic bags we often use are made of polyethylene or polypropylene, but thicker. The black and red plastic bags are made of polyvinyl chloride. In addition, even if these plastic bags are made of non-toxic polyethylene or polypropylene, it cannot be guaranteed that these plastic bags can be used for food. Because of the process of processing these materials into plastic bags, it is necessary to add auxiliary materials such as additives, dyes and other harmful human health. Therefore, the colored plastic bags that are commonly found on the market should not be used for direct food. However, it should be no problem to use vegetables, but it is best not to use these plastic bags to store vegetables. Because of the long time, toxins may penetrate into vegetables.

Secondly, experts also remind everyone to use it carefully for the white plastic bags that we use to directly load food. In particular, do not install oily, alcoholic foods and foods with temperatures above 60 degrees Celsius, otherwise the lead in the plastic bags will be incorporated into the food. Colored plastic bags are even less able to hold these foods.

Finally, we must remind everyone that there are uniform standards for the quality of plastic bags, and many of them have quality problems. Therefore, it is recommended that you use plastic bags as little as possible, which is beneficial to your own health and environmental protection.

After four days of field investigations and access to information, we learned about the dangers of plastic bags, the “partners” we intimately contact every day, because this harm is not only protecting our homeland, but also protecting ourselves. Let us start today, reject plastic bags, reject white pollution, and hold hands with green.

Third, advocate its future

Once upon a time, plastic bags, the items that we touch every day, seem to have become part of our lives. It is undeniable that it does bring a lot of convenience to our lives, but when you have used it in the process of using it, have you ever thought about it? Will it also harm our bodies? During the holiday, after four days of actual investigations and interviews, I felt a lot and benefited a lot.

It turns out that our "partners" who are in contact every day are really swallowing up our health a little bit. The thicker black and red plastic bags that we often use are made of polyvinyl chloride-containing PVC, while others All kinds of plastic bags also contain various additives such as additives, dyes and other harmful human health materials, so plastic bags are still used less. In the investigation, I also found that there are some austerity businesses who know a lot about the harm of plastic bags. However, in order to improve the health of consumers, they continue to use plastic bags in large quantities, so we have plastic bags. The understanding really did not improve to a certain height.

Of course, if we process plastic bags into other plastic products, it will not harm us, but it will bring convenience to our lives.

Therefore, as the master of the new century, we should start from the self, starting today, reject plastic bags, reject white pollution, and always accompany the green life.
