1, what are the behaviors that pollute the environment
Common environmental pollution is air pollution, water pollution, soil pollution, noise (sound) pollution, pesticide pollution, radiation pollution, thermal pollution.
1Radiation pollution refers to the appearance of radioactive substances or rays exceeding the national standard on the surface or inside of materials, human bodies, places, and environmental media due to human activities.
2 water pollution: the formation of the cause is a body of water due to the intervention of a certain substance, and lead to its chemical, physical, biological or radioactive pollution and other aspects of the characteristics of the change, thus affecting the effective use of water, endangering human health or damage to the ecological environment, resulting in the deterioration of water quality
3 air pollution:: the formation of the cause is the concentration of pollutants in the air reaches or exceeds the degree of harmfulness, resulting in the destruction of ecosystems and the normal survival of human beings. damage to the ecosystem and the normal survival and development of human beings, causing harm to people and living things. It mainly comes from carbon monoxide and hydrogen sulfide etc. emitted by factories, automobiles, power plants etc.
4 noise pollution: the formation of causes including traffic noise motor vehicles, ships, subways, trains, airplanes and other noise. Industrial noise factory noise generated by a variety of equipment. The sound level of industrial noise is generally higher, and has a greater impact on workers and surrounding residents. Construction noise mainly comes from the noise emitted by construction machinery. Construction noise is characterized by greater intensity. Noise from people's social activities and household appliances and audio equipment. Because of the close contact with people's daily life, so that people can not be quiet at rest, especially annoying, very easy to cause neighborhood disputes.
Two, what are the hazards of environmental pollution?
1. Hazards to human health
People need to breathe air to maintain life. An adult breathes about 20,000 times a day, inhaling 15 to 20 cubic meters of air. Therefore, polluted air has a direct impact on human health.
The harm of air pollutants on the human body is multifaceted, manifested in the respiratory system damage, physiological dysfunction, digestive system disorders, neurological anomalies, intellectual decline, carcinogenic, disabling. People call this disaster smog "killer smog". When the concentration of pollutants in the atmosphere is very high, it can cause acute pollution poisoning, or worsen the symptoms of the disease, and even take the lives of thousands of people in a few days. In fact, even if the concentration of pollutants in the atmosphere is not high, but the human body adult months and years of breathing this polluted air, will also cause chronic bronchitis, bronchial asthma, emphysema and lung cancer and other diseases.
2. Harm to plants
Atmospheric pollutants, especially sulfur dioxide, fluoride and other harm to plants is very serious. When the concentration of pollutants is very high, it will produce acute harm to plants, so that the plant leaf surface injury spots, or directly make the leaves withered and fall off; when the concentration of pollutants is not high, it will produce chronic harm to plants, so that the plant leaves green, or the surface can not be seen on the symptoms of the harm, but the plant's physiology has been affected, resulting in a decline in plant yields, the quality of the deterioration.
Legal basis:
"The Chinese People's **** and State Water Pollution Prevention and Control Law"
Article 42 of the pollutants discharged by enterprises, institutions and other producers and operators shall take measures to prevent and control the production of wastewater, wastewater, waste, slag, medical wastes, dust, foul-smelling gases, radioactive substances, and noise, vibration, and the production and construction of other activities. gases, radioactive substances, and noise, vibration, optical radiation, electromagnetic radiation and other pollution and harm to the environment.
Article 43 Enterprises, institutions and other producers and operators that discharge pollutants shall pay sewage charges in accordance with the relevant state regulations. Sewage charges shall be fully earmarked for the prevention and control of environmental pollution, any unit or individual shall not be retained, squeezed or diverted for other purposes.
Article 44 of the state to implement the total emission of key pollutants control system. Key pollutant emission control targets issued by the State Council, the people's governments of provinces, autonomous regions and municipalities directly under the Central Government to break down the implementation. Enterprises and institutions in the implementation of national and local standards for the discharge of pollutants at the same time, should comply with the decomposition of the total amount of key pollutant emissions control indicators implemented into the unit.
