Health effects of the environment
At present, extensive scientific material has been accumulated proving the direct impact of a number of environmental factors (climate, weather, ecological situation) on human health.
Based on extensive material, biometrics (a science that studies the dependence of well-being on weather) has developed a kind of “calendar” of diseases that are characteristic of the middle geographical latitudes of the northern hemisphere. So, in winter, flu and colds are more common than in summer, however, if it is a dry winter, they get less sick; if the weather is with sharp fluctuations in temperature, then the strength of its impact is compared with the health damage caused by epidemics. Inflammation of the lungs is more often affected in January, the peak of ulcerative bleeding occurs in February; rheumatism worsens in April. Winter and summer are characterized by skin diseases.
The environmental situation also affects human health. Violation of the ecological balance or the so-called ecological scissors are dangerous in disrupting the mechanism of human adaptation.
The body responds with various disorders to the harmful effects of physical radiation: occupational diseases to unpreparedness for new professions; neuropsychic instability on information overload and overpopulation, excessive noise in cities; allergic reactions to changes in the chemical composition of the environment.
The ability to adapt to negative influences is different in people with different levels of health, physical fitness. Adaptive features of a person depend on the type of his nervous system. The weak type (melancholic) adapts harder and is often prone to serious breakdowns. The strong, mobile type (sanguine) is psychologically easier to adapt to new conditions.
At the same time, as special studies have shown in people with a higher level of physical fitness, the body's stability is significantly higher than in individuals with general physical fitness.

Health effects of the environment
- Types of chemical environmental pollution, their impact on health
Chemical pollution of the environment with substances unusual for it (xenobiotics) is currently the most ambitious and significant. The main harmful substances that pollute the atmospheric water are the following: a) nitrogen oxides, especially nitrogen dioxide - a colorless odorless poisonous gas that irritates the respiratory system when increased

Module 3. The effects of the environment and heredity on health
- Types of physical pollution of the environment and their impact on the human body
Physical pollution is pollution associated with changes in the physical parameters of the environment. Depending on which parameters exceed the MPC, the following types of physical pollution are distinguished: - thermal - light; - noise; - electromagnetic; - radioactive, - radiation .. Temperature (thermal) pollution. Important weather element
- The influence of microorganisms and environmental factors on the quality of products
Food products containing 30% water or more are a good breeding ground for microorganisms. During propagation, microorganisms secrete enzymes that decompose proteins (proteolytic), fats (lipolytic), carbohydrates (amylolytic) to intermediate or final decomposition products. At the same time, the properties of the products change for the better or for worse. The ability of microorganisms to improve
- The influence of environmental factors on the development and survival of eggs and larvae of helminths
Oxygen. It has been established that about 0.0009 cm3 of oxygen is required for the development of Ascafis suilla eggs. Mature A.suilla eggs need less oxygen than developing eggs. Each egg in the process of development requires 0.0000025-0.0000031 cm3 of oxygen. With the cessation of oxygen access, the further development of helminth eggs stops and can continue during aeration. Egg survival
- Public health as an integral criterion for assessing the state of the environment
In May 1998, the World Health Assembly approved the World Health Declaration for countries belonging to WHO, which noted that improving the health and material condition of the population is the ultimate goal of social and economic development. The importance of the health problem has especially increased recently, as the health status of the population has changed significantly,
- MEASUREMENT OF COMMUNICATION BETWEEN PHENOMENA. METHODS FOR STUDYING CORRELATION RELATIONS IN THE EVALUATION OF HEALTH INDICATORS AND ENVIRONMENTAL FACTORS
LESSON PURPOSE: To master the principles of measuring correlation and master the technique of measuring the relationship between phenomena. LESSON METHODOLOGY: Students independently prepare for a practical lesson in the recommended literature and complete their individual homework. The teacher within 10 minutes checks the correctness of homework and indicates the allowed
- ENVIRONMENTAL PROTECTION
Currently, the Republic of Kazakhstan has developed an unfavorable environmental situation. This is largely facilitated by the fact that for many decades Kazakhstan has developed an advantage in the raw materials system of nature management. This was accompanied by extremely high technological pressures on the environment. Therefore, a radical improvement of the environmental situation did not happen, and she
- Environmental protection
Environmental protection from pollution includes the following measures: 1. Of particular importance are legislative measures that determine the responsibility of various organizations for environmental protection (federal laws and regulations). Development of hygiene standards establishing MPC, SDA, PDU for pollutants. 2. Technological activities should
- PATHOLOGY CAUSED BY ENVIRONMENTAL FACTORS
The words of the famous physician of antiquity Paracelsus (1493-1541), who believed that "Everything is poison and nothing is poisonous" can be put as an epigraph to this lecture. In fact, the problem of pathology caused by environmental factors covers almost all human diseases. Some diseases, of which there are many, are caused by direct exposure to unfavorable factors.
- SANITARY AND PARASITOLOGICAL SUPERVISION OF OBJECTS OF THE ENVIRONMENT
The causative agents of parasitic diseases, as mentioned above, are widespread in the environment and can survive in it for a long time, while maintaining their invasiveness. In this regard, in our opinion, sanitary-parasitological surveillance (SPN) of environmental objects is an important component of preventive work in cases of parasitosis. Sanitary and parasitological surveillance
- LUNG DISEASES DUE TO ENVIRONMENTAL FACTORS
Frank E. Speizer This chapter focuses on the perspectives of environmental assessment of lung disease. This assessment is very important, since the elimination of harmful factors from the environment can often be the only way to prevent further deterioration of the patient's condition. In addition, the identification of these diseases in one patient may
- Environmental condition
From the moment of its appearance on Earth, a person is constantly confronted with the need to fight for life, with adverse environmental conditions, with natural factors, with the unpredictability of even the near future. Environmental factors that affect the body include: energy effects (including physical fields), the dynamic and chemical nature of the atmosphere, and water
- ENVIRONMENTAL ACTIVITIES FROM PARASITOSIS PATTERNS
In the prevention of invasive diseases, regardless of the mechanism of infection and transmission pathogens, it is necessary to take into account not only their biological characteristics, but also the influence of certain conditions of the social environment in which the epidemic process develops. This position is especially clearly confirmed in intestinal parasitoses (helminthiases, protozoa), when the role of sanitary-hygienic
- The concept of environmental pollution, its sources, types
All processes in the biosphere are interconnected. It is well known that nature is the necessary environment for the existence of mankind and at the same time is the source of all the material goods it consumes. From the first moments of life to the last minute, the human body interacts with the external environment. The external (environment) environment as an integral system includes a large number of different factors affecting
