What are the hazards of garbage to the environment

Times are progressing, science and technology are also progressing, and all kinds of garbage are emerging in an endless stream. Do you know the environmental hazards of garbage teams when discarding garbage? If it is not clear, let's look at the following.

First, dumping garbage occupies a large amount of land. The garbage belt surrounds the whole country, covering an area of 800,000 mu, and garbage explosion accidents continue to occur.

Second, garbage explosion accident: with the increase of organic matter content in cities and the change from open-air scattered stacking to centralized stacking, the anaerobic environment that produces methane gas is easily covered by simple cover, and the stacking becomes centralized stacking. The anaerobic environment that produces methane gas is easy to be covered by simple cover, which is flammable and explosive.

Thirdly, the large amount of harmful gases such as ammonia and sulphide released from the open-air refuse dump has seriously polluted the atmosphere and the living environment of the city. The living environment of the city. Seriously polluted water. Garbage not only contains pathogenic microorganisms, more than 60% of municipal solid waste is mainly produced by secondary pollution of residential organic waste. That is to say, the increasing organic waste in residential areas is the source of increasing municipal solid waste.

Fourth, seriously polluted water: garbage not only contains pathogenic microorganisms, but also produces a large number of acidic and alkaline organic pollutants in the process of stacking corruption. It will dissolve the heavy metals in garbage, produce a large number of acidic and alkaline organic pollutants, and dissolve the heavy metals in garbage to form organic substances. Heavy metals and pathogenic microorganisms are three integrated pollution sources, substances, heavy metals and pathogenic microorganisms are three integrated pollution sources. Leachate produced by rainwater infiltration will inevitably cause serious pollution of surface water and groundwater. It causes serious pollution of surface water and groundwater.

Fifth, biological pollution: There are many pathogenic microorganisms in garbage. At the same time, garbage is often the breeding ground of mosquitoes, flies, cockroaches and rats, which will inevitably endanger the health of the general public. The breeding grounds of salamanders and rats are bound to endanger the health of the general public.
