1. Environment refers to the totality of various natural and artificially modified natural factors affecting human survival and development, including atmosphere, water, ocean, land, mineral deposits, forests, grasslands, wildlife, natural monuments, nature reserves, scenic spots, cities and villages.
Second, China's environmental protection policy comprehensive planning, rational layout, comprehensive utilization, harm into profit, relying on the masses, everyone to do it, protect the environment, benefit mankind.
3. Environmental protection refers to the general term for various actions taken by human beings to solve actual or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure sustainable economic and social development. Its methods and means include engineering and technical aspects, administrative management, as well as legal, economic, publicity and education.
1972. World Environment Day: The United Nations held the "United Nations Conference on the Human Environment" in Stockholm, Sweden, on June 6, 5, and since then June 6 has been World Environment Day every year.
5. Sustainable development that meets the needs of the present without jeopardizing the needs of future generations.
Sixth, the greenhouse effect carbon dioxide and water vapor in the air can absorb the heat lost by the ground, but part of the heat energy is retransmitted back to the earth, which plays a role in insulating the ground, and this effect similar to the greenhouse is called the greenhouse effect.
7. "White pollution" foam tableware, plastic bags, etc. are differentiated because they are difficult to degrade, and produce toxic gas when burned, and will damage the soil structure when landfilled. Therefore, it is called "white pollution".
8. "Acid rain": Sulfur dioxide or nitrogen oxides artificially emitted and nitrogen oxides in automobile exhaust will form highly corrosive acid precipitates when encountering water vapor. It's called "acid rain".
5. Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds (metals weighing metals with a specific gravity of more than <>; Environmental pollution refers to heavy metals mainly refer to mercury, cadmium, lead, chromium and arsenic and other toxic heavy metals, also refers to zinc, copper cobalt, nickel, tin and so on with certain toxicity).
PM10 refers to particulate matter with an aerodynamic equivalent diameter of less than 10 microns, also known as inhalable particulate matter or dust.
PM2.5 refers to particulate matter with a diameter of less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs.
12. Water pollution refers to the phenomenon that the chemical, physical, biological or radioactive characteristics of a water body are changed due to the intervention of a substance, thereby affecting the effective use of water, endangering human health or damaging the ecological environment, and causing deterioration of water quality.
13. Solid waste refers to solid and semi-solid waste generated in production, construction, daily life and other activities that pollute the environment.
14. Hazardous waste refers to one or more hazardous wastes with corrosive, toxic, flammable, reactive and infectious characteristics listed in the national hazardous waste list or identified in accordance with the national hazardous waste identification standards and identification methods, and solid wastes with the above hazardous characteristics that are not excluded.
15. Environmental noise refers to the sound generated in industrial production, building construction, traffic construction, transportation and social life that interferes with the surrounding living environment.
16. Environmental noise pollution refers to the phenomenon that the environmental noise generated exceeds the environmental noise emission standards stipulated by the state and interferes with the normal life, work and study of others.
17. The "three simultaneities" of environmental protection of construction projects means that the equipment (facilities) for pollution prevention and control in new construction, reconstruction and expansion projects must be designed, constructed and put into operation at the same time as the main project.
18. Cleaner production refers to the continuous adoption of measures such as improving design, using clean energy and raw materials, adopting advanced technology and equipment, improving management and comprehensive utilization, etc., to reduce pollution at the source, improve the efficiency of resource utilization, and reduce or avoid the generation and discharge of pollutants in the process of production, service and product use, so as to reduce or eliminate harm to human health and the environment.
19. Environmental emergenciesEnvironmental emergencies refer to emergency environmental incidents that occur suddenly, cause or may cause major casualties, property losses, damage to the ecological environment and serious social harm, and endanger public safety.
20. Environmental impact assessment refers to the methods and systems for analyzing, predicting and assessing the environmental impacts that may be caused by the implementation of planning and construction projects, proposing countermeasures and measures to prevent or mitigate adverse environmental impacts, and tracking and monitoring.
Environmental pollution refers to the phenomenon that human activities cause changes in environmental elements or their status, deteriorate environmental quality, and disturb and destroy the stability of ecosystems and the normal living conditions of human beings.
