Due to environmental pollution, there is a decrease in soil fertility, land degradation and desertification, loss of flora and fauna, deterioration of the quality of atmospheric air, surface and groundwater. Overall, this leads to the disappearance from the face of the Earth of whole ecosystems and biological species, deterioration of the health of the population and a decrease in the life expectancy of people.
Most diseases of a modern person are associated with adverse environmental conditions. Not only is the health of people falling dramatically: previously unknown diseases have appeared, and their causes are hard to establish. Many diseases have become more difficult to cure than before.
The negative impact on human health and the environment is exerted by industrial enterprises located in the territory of the city, especially near residential areas. These are enterprises of ferrous and nonferrous metallurgy, coal and ore mining and processing industries. All these objects of the national economy are powerful sources of emissions of harmful substances into the atmosphere. As a result of human activities, there are various solid and gaseous substances in the atmosphere. Oxides of carbon, sulfur, nitrogen, hydrocarbons, lead compounds, dust, etc., entering the air have a toxic effect on the human body.
The harmful substances in the atmosphere affect the human body upon contact with the skin or mucous membrane. Along with the respiratory system, pollutants affect the organs of sight and smell. Polluted air irritates most of the respiratory tract, causing bronchitis, asthma, worsens the overall health of a person: there are headaches, nausea, weakness, reduced or lost work capacity. It has been established that such industrial wastes as chromium, nickel, beryllium, asbestos, and many toxic chemicals cause cancer.
Unfortunately, drinking water can have a negative effect on human health too. Diseases transmitted through polluted water cause deterioration of health, and the death of a huge number of people. Open water sources are especially polluted: rivers, lakes, ponds. There are many cases when polluted water sources caused epidemics of cholera, typhoid fever, dysentery, which are transmitted to humans as a result of contamination of water basins with pathogens and viruses.
The sources of soil pollution are agricultural and industrial enterprises as well as residential buildings. At the same time, from industrial and agricultural facilities chemical (including very harmful to health: lead, mercury, arsenic and their compounds), as well as organic compounds enter the soil. From the soil, harmful substances and pathogenic bacteria can penetrate into the groundwater, which can be absorbed from the soil by plants, and then through the milk and meat into the human body. Diseases such as anthrax and tetanus are transmitted through the soil.
The Effect on Human Health
2. Air and water pollution by industrial enterprises.
3. Food quality.
4. Composition of atmospheric air.
The environment is the collection of all that is around a person in the continuation of his/her life. It consists of natural components, such as: land, air, water, solar radiation, and man-made factors, which include all manifestations of human civilization. The health of the human body is directly or indirectly influenced by the various properties and qualities of all environmental factors. Let’s consider the most important of them:
1. Climatic factors
Weather conditions have a great impact on well-being and normal human performance. For example, if the air temperature has dropped significantly, you need to protect the body from hypothermia. Without doing this, a person is at risk of developing acute respiratory infections.
Environmental factors, such as changes in atmospheric pressure, humidity, the electromagnetic field of the planet, precipitation in the form of rain or snow, movement of atmospheric fronts, cyclones, or wind lead to changes in health. They can cause headaches, exacerbation of diseases of the joints, drops in blood pressure. However, weather changes ambiguously affect different people. If a person is healthy, the attunement with new climatic conditions will quickly occur in the body and unpleasant sensations will pass by. A sick or weakened human body has an impaired ability to quickly tune into weather changes, so it suffers from general malaise and pain. Try to maintain your health level at the proper level, respond to environmental changes in a timely manner, and climatic factors will not cause you discomfort. To acclimatize your body, do daily exercises, walk for an hour, follow the daily regimen.
2. Chemical and biological factors
The technogenic activity of people leads to an increase in emissions of industrial waste. Chemical compounds from waste enter the soil, air, and water, and then, through the use of contaminated food and water, inhaling air saturated with harmful elements, enter the body. Consequently, all human organs, including the brain, contain several milligrams of poisons. Exposure to toxic substances may cause nausea, coughing, and dizziness. If they regularly get inside, then the development of chronic poisoning is possible.
The symptoms include fatigue, insomnia or drowsiness, apathy, frequent mood swings, impaired attention, and psychomotor reactions. If you suspect you have the signs of chronic poisoning, you should undergo a medical examination and take measures, and maybe even change your place of residence if it threatens your life and health. Biological factors are countless viruses, bacteria, parasites that are constantly present in the environment. In order to protect oneself from them, one should pay attention to hygiene: wash hands before eating, boil drinking water, and immediately disinfect skin damage.
Eating food is one of the basic instincts of the body. The supply of nutrients necessary for normal life comes from the external environment. Medical studies have shown that for optimal physiological processes, good nutrition is a necessary condition. Every day the body needs a certain amount of protein compounds, carbohydrates, fats, elements and vitamins. In the case when the food is inadequate, there is a risk of development of diseases of the cardiovascular system, digestive canals, disturbance of metabolic processes.
For example, the constant overeating of foods rich in carbohydrates and fats can cause obesity, diabetes, vascular and heart muscle diseases. The use of genetically modified organisms and products that contain elevated concentrations of harmful substances leads to the deterioration of general health and the development of a wide range of diseases. Overall, all this comes to the person from the environment, so one should be careful when choosing food.
