What kind of health hazards garbage brings to us

Polluting the air. Garbage is a complex mixture. In the process of transportation and open stacking, the decomposition of organic matter produces foul odor, and releases a large number of ammonia, sulfide and other pollutants to the atmosphere, including more than 100 kinds of organic volatile gases, which contain many carcinogenic and teratogenic substances.

Plastic film, paper scraps and dust are blown by the wind to form "white pollution".

Polluting water bodies. The harmful components in the garbage are easily washed into the surface water body through rainwater, and a large number of acidic and alkaline organic pollutants will be produced in the process of garbage stacking or pit filling, and the heavy metals in the garbage will be dissolved at the same time. The leachate produced by the garbage pollution source will enter the groundwater body through soil infiltration; Waste is disposed of directly into rivers, lakes or oceans, causing even more pollution.

You see: plastic bottles and lunch boxes floating on the surface of the Summer Palace and Beihai Sea, plastic bags and bread wraps scattered on the forest and mountain roads in Xiangshan and Bada and hanging on tree branches, etc., some tourists only want their own convenience, causing pollution of the tourism environment. If an animal accidentally ingests white garbage, it will not only harm health, but even lead to death.

Nests of pests. Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding places for rats, birds, mosquitoes and flies, and is also a source of infectious diseases.

With the increase of quantity, there is a devastating damage to the ecology and resources, which poses a great threat to human health. The harm of garbage to the environment mainly includes: (1) pollution to the water environment, (2) pollution to the atmospheric environment, (3) erosion of land, (4) harm to human health, and (5) impact on economic development.

Garbage can be divided into many categories and can be harmful to humans from all aspects.

In today's world, garbage is infested, and the whole earth seems to be full of garbage. Garbage is also competing with humans for living space. When garbage is piled up in the open air, when strong winds blow and when it is burned, the garbage dust will pollute the atmosphere.

Rainwater from open-air garbage dumps leaks into the ground and pollutes water sources. Untreated waste is used on farmland, which contaminates crops and causes many diseases if people eat contaminated food and vegetables.

Improper waste disposal can cause pollution, which is not only unhygienic, but can also encroach on land, clog rivers, and endanger crop growth and human health. In the city, due to the increasing population, domestic garbage.

It is increasing at a rate of 10% per year, causing a major public nuisance. The harm of garbage is serious, first of all, it encroaches on a large amount of land;The second is polluting farmland;The third is to pollute groundwater;Fourth, polluting the atmosphere;Fifth, the spread of diseases. Therefore, we advocate the separation of garbage for effective secondary use or harmless disposal.

A significant portion of newspapers are recyclable paper;Glass bottles can also be used over and over again. Garbage sorting and collection is a common method at present. If 40% of the reusable substances in the household waste are recovered, the amount of garbage will be greatly reduced.

Every year, a large number of waste newspapers are produced in the world, and the main use in the past was to send paper mills to make recycled paper paddles. Today, two research institutes in the United States have developed two new and more valuable uses for waste newspapers. The first is to use waste newspapers to improve royal soil;The second is to chop up waste newspapers and make them into feed for cattle and sheep.

First, it occupies too much space.

The garbage piled up on the outskirts of the city encroaches on a large amount of farmland. The time for garbage to stay in nature is also very long: 2 weeks for apple cores;Cigarette butts, wool fabrics 1-5 years;Orange peel 2 years;Painted planks for 13 years;Nylon fabric 30-40 years;Leather 50 years;Cans 80-100 years;Plastic 100-200 years;Glass 2000.

Second, air pollution.

The open stacking of garbage will release a large number of harmful gases such as ammonia and sulfide, which will seriously pollute the atmosphere and the living environment of the city. It contains more than 100 kinds of organic volatile gases, and these releases contain many carcinogenic and teratogens. Plastic film, paper scraps and dust are blown by the wind to form "white pollution".

The significance of garbage sorting:

Garbage classification is an important part of the pre-disposal of garbage, and it is the key to realize the reduction of garbage and reduce environmental pollution from the source. Waste mixed and burned together can release harmful gases, cause air pollution, and pose health risks to the public. The classification of domestic waste can improve the efficiency of subsequent waste treatment and reduce the difficulty of treatment, which is an important starting point for the development of circular economy.

For example, combustible components with high calorific value are burned to generate electricity to improve thermal efficiencySorting out easily degradable organic matter for composting can improve composting efficiency and quality.

What are the hazards of garbage and how to classify garbage, 4 pictures make it easy for you to grasp.

This is a big question, and it's not just medical knowledge that can answer it. There are five main types of municipal solid waste: waste paper, plastic, glass, metal, and biological waste. The main hazards brought by waste to human life and the environment are:

Takes up too much space, pollutes the air, pollutes the water, fire hazards, nests of pests, etc. For medical waste, the state has clear requirements, it is classified **, which can be assured.
