The harm of garbage to human beings, what are the hazards of garbage

Hazardous waste refers to waste batteries, waste lamps, waste medicines, waste paint and their containers, and other domestic wastes that cause direct or potential harm to human health or the natural environment. Common ones include waste batteries, waste fluorescent tubes, waste light bulbs, waste water silver thermometers, waste paint buckets, waste household appliances, expired drugs, expired cosmetics, etc.

Food waste is uniformly disposed of according to the solid waste treatment method. The treatment methods mainly include physical method, chemical method, biological method, etc.; The specific treatment technologies include landfill, incineration, composting, fermentation, etc., in short, its resource reuse shows a trend of diversification. According to the different application scopes and actual situations, the following methods are mainly introduced.

1. Physical sorting and processing is mainly to use a series of methods to realize the separation of various components in the garbage, and then unify it. On the one hand, this method achieves a great deal of utilization, and on the other hand, it minimizes the pollution that may be caused by garbage. However, due to its high cost, most countries do not use this method, except for a few developed countries.

2. Crushing the straight row method, the United States has successfully developed the individual family as early as the 40s of the last century....

1. Occupy too much land. Garbage piled up on the outskirts of the city encroaches on a large amount of farmland. At present, the average annual output of garbage per person in Beijing is 440 kilograms, and the annual output of the city is about 4 million tons, which is equivalent to two and a half view mountains.

There are more than 4,500 garbage dumps in Beijing, covering an area of more than 10,000 acres. Garbage stays in nature for a long time: cigarette butts, woolen fabrics for 1-5 years; orange peel 2 years; 13 years of painted boards; nylon fabric 30-40 years; leather 50 years; cans 80-100 years; 100-200 years for plastics; Glass 1000 years.

2. 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".

3. 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.

Extended Information: Ways to Protect the Environment:

1. Prevent vandalism.

Prevent environmental damage caused by construction and development activities, including preventing environmental pollution and damage caused by the construction of large-scale water conservancy projects, trunk highways, large ports and wharves, airports and large-scale industrial projects, agricultural reclamation and lake-enclosing activities, offshore oil fields, coastal zones and marshlands, development of forests and mineral resources, and environmental damage and pollution caused by the establishment and construction of new industrial zones and new towns.

2. Nature conservation.

The protection of the natural environment with special value includes the effective protection of rare species and their living environment, special natural development history relics, geological phenomena, landforms, etc. In addition, urban and rural planning, controlling soil erosion and desertification, afforestation, controlling the growth and distribution of population, and rationally allocating productive forces are also part of environmental protection. Environmental protection has become one of the common actions and main tasks of the world's leading countries and peoples today.

China has declared environmental protection as a basic national policy of China, and has formulated and promulgated a series of laws and regulations on environmental protection to ensure the implementation of this basic national policy. Environmental pollution problems have occurred to varying degrees in the world, and the aspects with global impact include atmospheric environmental pollution, marine pollution, and urban environmental problems. With the globalization of the economy and the world, environmental pollution is also increasingly showing an international trend, and the transboundary transfer of hazardous waste is a prominent manifestation in this regard.

Garbage contains a large amount of combustibles, and methane and other combustible gases will be produced in the process of stacking.

Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding grounds for rats, birds, mosquitoes and flies, and is also the root cause of infectious diseases.

Seeing the harm of the above garbage to human beings, do you still dare to litter?

In order to protect our environment, garbage should be separated.

Domestic garbage is divided into: hazardous waste, kitchen waste, and other garbage.

can be ** things; Refers to the domestic garbage that is suitable for the use of resources without pollution, including: waste paper, waste plastics, waste metal, waste packaging, waste textiles, waste furniture, waste books, waste electrical and electronic products, waste glass, plastic and aluminum packaging, etc.;

hazardous waste; Refers to domestic garbage that causes direct or potential harm to human health or the natural environment, including: waste cadmium batteries, waste mercury oxide batteries, waste lead-acid batteries and other waste batteries, waste fluorescent tubes, waste energy-saving lamps and other waste fluorescent tubes, waste thermometers, waste blood pressure monitors, waste drugs and their packaging, waste paints, solvents and their packaging, waste pesticides, disinfectants and their packaging, waste film and waste photo paper, waste mineral engine oil and its packaging, etc.;

food waste; Refers to organic wastes that are easy to decay and deteriorate under ordinary storage conditions, including: kitchen waste generated by unit canteens, hotels, restaurants, households, etc., vegetables, melons and fruits, garbage, rotten meat, meat and bones, eggshells, offal of livestock and poultry products, etc., produced by food processing, bazaars, agricultural products wholesale markets, etc.;

other garbage; Refers to other household garbage except for objects, hazardous waste and kitchen waste.

Domestic garbage should be put in a classified manner.

It can be put into this collection container, or handed over to the renewable resource station.

Hazardous waste is put into the hazardous waste collection container, or handed over to the hazardous waste ** station.

Kitchen waste is put into the kitchen waste collection container, and if it can be disposed of locally, it can be directly put into the designated point for on-site disposal.

Other garbage is disposed of in other garbage collection containers.

Bulky garbage such as waste furniture, waste electrical products, etc., which is large in size, strong in integrity or needs to be split and reprocessed, shall be reserved or entrusted to a property service enterprise, and an appointment shall be made for the collection of renewable resources ** operators or operators engaged in collection and transportation services in accordance with the law, or temporarily stacked in the designated place.

As long as everyone consciously protects the environment and does not litter, our earth will become more beautiful.

1. Seriously pollute water bodies. Garbage not only contains pathogenic microorganisms, but also produces a large number of acidic and alkaline organic pollutants in the process of stacking and decaying, and will dissolve the heavy metals in the garbage, and the leachate produced by rainwater will inevitably cause serious pollution of surface water and groundwater.

2. Biological pollution. There are many pathogenic microorganisms in garbage, and garbage is often a breeding ground for mosquitoes, flies, cockroaches and rats, which inevitably endangers the health of the general public.

3. Encroachment on a large amount of land. According to preliminary surveys, in 2003, 2 3 out of 668 cities in the country were surrounded by garbage patches. The total area of garbage storage in the country is 800,000 mu.
