What are the hazards of environmental pollution? We all know that environmental pollution is a bad word, but we can't stop some environmental pollution. In recent years, environmental pollution has become more and more serious, and many people are worried about the harm caused by environmental pollution. What are the hazards of environmental pollution?
What are the hazards of environmental pollution 1 1 and what are the hazards to human health?
When the concentration of pollutants in the atmosphere is high, it will cause acute pollution poisoning, or aggravate the symptoms, and even kill thousands of people within a few days. In fact, even if the concentration of pollutants in the atmosphere is not high, breathing this polluted air all the year round will cause chronic bronchitis, bronchial asthma, emphysema, lung cancer and other diseases.
2. Environmental pollution and cancer
Environmental pollution is an extremely important cause of cancer. Relying on the strength of the whole society and taking comprehensive measures to effectively control environmental pollution is an important part of comprehensive cancer prevention and control measures.
3. Damage to plants
Air pollutants, especially sulfur dioxide and fluoride, are very harmful to plants. When the concentration of pollutants is high, it will cause acute damage to plants, damage to the surface of plant leaves, or directly cause leaves to wither and fall off;
When the concentration of pollutants is not high, it will cause chronic damage to plants, make the leaves of plants fade, or have no harmful symptoms on the surface, but the physiological functions of plants are affected, leading to the decline of plant yield and deterioration of quality.
According to the nature and source of environmental pollution:
Land pollution: garbage disposal has become an important issue in major cities. Tens of millions of tons of garbage every day, many of which cannot be burned or corrupted, such as plastics, rubber, glass and other enemies of mankind.
Marine pollution: mainly crude oil leaked from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories and acidic solutions from mines; They pollute most marine lakes. Therefore, not only marine organisms are harmed, but birds and humans may also be poisoned by eating these organisms.
Air pollution: refers to the concentration of pollutants in the air reaching or exceeding the harmful level, which leads to the destruction of the ecosystem and the normal survival and development of human beings, and causes harm to people and creatures. This is the most direct and serious, mainly from carbon monoxide and hydrogen sulfide released by factories, automobiles and power plants. Every day, people suffer from diseases of respiratory organs or visual organs due to contact with these dirty air.
Water pollution: refers to the phenomenon that the chemical, physical, biological or radioactive pollution of water changes due to the intervention of certain substances, thus affecting the effective use of water, endangering human health or destroying the ecological environment, and leading to the deterioration of water quality.
What are the hazards of environmental pollution? 2. Suggestions and countermeasures to prevent and solve indoor environmental pollution.
1, improve local laws and regulations and straighten out management relations. Seeking and developing pollution-free, pollution-free, sustainable and healthy green indoor environment should be the main goal of Jiangsu's future environmental construction and development. Therefore, it is necessary to formulate a long-term plan and improve the legal system, standardize the production, operation and management of home improvement materials, and make them embark on a pollution-free track as soon as possible.
2, improve the quality monitoring system of building materials and decorative materials products, strengthen law enforcement.
3, urban construction and health departments should increase publicity and popularization, to help the masses consciously establish environmental awareness of green decoration. We should increase investment in science and technology, organize scientific research, teaching, promotion and production departments to strengthen the product development of pollution-free green building decoration materials. Do a good job in producer training, improve the quality of production and sales personnel, and let more people know the negative impact of indoor environmental pollution on society. Regularly increase the publicity of newspapers, television and advertisements. It is suggested that green decoration, environmental protection building materials and safety education should be included in the curriculum system of primary and secondary schools to improve the awareness of anti-virus and pollution prevention of relevant families.
4, actively promote and support the production and operation of pollution-free building materials and pollution-free decorative materials. Strengthen market supervision and management, popularize market access system, crack down on counterfeiting, maintain market order, and realize the enthusiasm of producers and operators to protect high quality and good price.
5. Strengthen the environmental inspection of public buildings and houses. Newly-built buildings, office buildings, residential buildings, hospitals and schools whose indoor environment is not up to standard shall not be accepted, and the indoor environment grade must be included in the important basis for rating star-rated buildings and kindergartens. After acceptance, the relevant functional departments and testing departments will issue green decoration signs.
6. Interior decoration shall be made of high quality, healthy and environmentally friendly materials that meet national standards. Generally speaking, artificial boards are the most likely to cause indoor pollution, so try to choose log building materials and furniture when conditions permit.
