What are the hazards of garbage pollution

Harm to the environment:

1. A large amount of ammonia, sulfide and other harmful gases are released from open piles of garbage, seriously polluting the atmosphere and the living environment of the city.

2. Serious pollution of water bodies. The garbage not only contains pathogenic microorganisms, but also produces a large number of acidic and alkaline organic pollutants in the process of stacking and rotting, and will dissolve the heavy metals in the garbage, forming an organic material, heavy metals and pathogenic microorganisms into a three-pronged pollutant, the leachate produced by the rainfall will inevitably result in the serious contamination of the surface water and groundwater.

3. Occupy a large amount of land. According to a preliminary survey, in 2003, 2/3 of the 668 cities in China were surrounded by garbage belts. The total land occupied by garbage is 800,000 mu.

4. More than 60% of the urban garbage is mainly generated by the secondary pollution of organic garbage from the residents of the community, that is to say, the increasing organic garbage in the community is the source of the increasing urban garbage. p>With the development of the economy and the improvement of people's lives, urban garbage has increased in large quantities. Garbage disposal has become an urgent problem in the comprehensive improvement of urban environment. Food is one of the three main elements of human life and health. Once food is contaminated, it has to jeopardize human health. Food contamination refers to a variety of food people eat, such as grain, fruits, vegetables, fish, meat, eggs, etc., in the production, transportation, packaging, storage, sales, cooking process, mixed with harmful toxic substances or germs.

Preventing food contamination, not only to pay attention to dietary hygiene, but also from the production, transportation, processing, storage, sales and other aspects. Only in this way can we get to the root of the problem.
