1、噪声污染
1. Noise pollution
是接近或超过人耳听觉承受限度的声音污染。能影响和改变人体正常的生理状态,甚至诱发疾病。主要来源于工业、交通运输等领域各种类型机器的运转。城市噪声已经是城市环境的一大公害。主要来源有:工业噪声、交通噪声、建筑施工噪声和社会生活噪声等。
It is the sound pollution that is close to or exceeds the hearing limit of human ears. It can affect and change the normal physiological state of the human body, and even induce diseases. It mainly comes from the operation of all kinds of machines in the fields of industry, transportation and so on. Urban noise has become a major public nuisance in the urban environment. The main sources are industrial noise, traffic noise, construction noise and social life noise.
2、土壤污染
2. Soil pollution
是人类活动产生的污染物进入土壤并积累到一定程度,引起土质恶化的现象。主要源于工业、生活废水和固体废物、农药和化肥以及大气沉降物等。
Pollutants produced by human activities enter the soil and accumulate to a certain extent, causing soil deterioration. Mainly from industrial, domestic wastewater and solid waste, pesticides and fertilizers, and atmospheric deposition.
3、农药污染
3. Pesticide pollution
光氧催化设备
农药及其降解产物对土壤、水体和大气的污染。主要指有机氯、有机磷和有机氮农药污染。严重时能引起人和动植物的急性或慢性中毒。是农药及其在自然环境中的降解产物,污染大气、水体和土壤,破坏生态系统,引起人和动植物急性或慢性中毒的现象。农药也分有机农药和无机农药。污染主要由有机氯农药、有机磷农药和有机氮农药等造成。造成农药污染的原因很多,比如长期使用一些禁用的高毒高残留农药,或在作物上滥施乱用等。
The pollution of pesticides and their degradation products to soil, water and air. Mainly refers to organic chlorine, organic phosphorus and organic nitrogen pesticide pollution. Severe cases can cause acute or chronic poisoning of human beings and animals and plants. Pesticides and their degradation products in the natural environment, polluting the atmosphere, water and soil, destroying the ecosystem, causing acute or chronic poisoning of human beings, animals and plants. Pesticides are also divided into organic pesticides and inorganic pesticides. Pollution is mainly caused by organochlorine pesticides, organophosphorus pesticides and organic nitrogen pesticides. There are many reasons for pesticide pollution, such as long-term use of banned high toxic and high residual pesticides, or indiscriminate use of crops.
4、化肥污染
4, chemical fertilizer pollution
过量施用化肥而引起水体、土壤和大气的污染。未被植物及时利用的氮化合物,若以不能被土壤胶体吸附的NO3—N的形式存在,就会随下渗的土壤水转移至根系密集层以下而造成污染。可导致河川、湖泊和内海的富营养化;土壤受到污染,物理性质恶化;食品、饲料和饮用水中有毒成分增加。为防止污染环境,应对使用的化学肥料进行控制和管理。
Excessive use of fertilizers causes water, soil and air pollution. Nitrogen compounds that are not used by plants in time, if they exist in the form of NO3-N which can not be adsorbed by soil colloids, will be contaminated by soil water transferred to the dense layer below the root system. It can lead to eutrophication of rivers, lakes and inland seas; contamination of soil and deterioration of physical properties; and increased toxic components in food, feed and drinking water. In order to prevent environmental pollution, chemical fertilizers should be used for control and management.
