1, abusing food additives. Including over-dose and over-range use of food additives.
2. Food packaging materials, containers and equipment. Include plastic, rubber, paint, ceramics, enamel and other materials.
3. Radioactive pollution in food. Including the harm caused by various radioactive isotopes polluting food raw materials. Aquatic products such as fish have a strong enrichment effect on some radionuclides, which needs special attention.
4. Human abuse of antibiotics, especially in China: According to the data published by the World Health Organization, one third of people who died of illness did not die from the disease itself, but from irrational drug use. Every year, 80,000 people in China die from antibiotic abuse! China has become one of the countries with the most serious abuse of antibiotics in the world.
5, improper use of highly toxic pesticide preparation, or use of highly toxic pesticide preparation without the required protective equipment, can easily lead to poisoning incidents.
Human abuse of chemicals has brought ecological disasters.
1. ozone layer destruction: after a large number of ozone layer depletion, its ability to absorb ultraviolet radiation is greatly weakened, resulting in an obvious increase in ultraviolet B reaching the earth's surface, which brings many hazards to human health and ecological environment.
2. Greenhouse effect: also known as "greenhouse effect", it is the common name of atmospheric heat preservation effect. Since the industrial revolution, carbon dioxide and other greenhouse gases with strong heat absorption emitted by human beings into the atmosphere have increased year by year, and the greenhouse effect of the atmosphere has also been enhanced, which has caused a series of problems and attracted the attention of all countries in the world.
3. Waste pollution and reduction of transferred forest area.
4. Decreased biodiversity: Animals, plants, microorganisms and other living things are regularly combined to form a stable ecological complex.
5. Nuclear pollution: the environmental damage caused by the residue after the leakage of nuclear substances, including the pollution caused by nuclear radiation and atomic dust, and the secondary pollution caused by these substances, such as the harm of water sources polluted by nuclear substances to people and animals.
