The World Health Organization declares that pollution levels exceeded in more than 50% of cities. According to statistics, the average inhabitant of a megapolis life for four years less compared to the population living in rural areas.
The question arises as to which pollutants are more likely to be present in the air of the room, what impact they have on human health, and how to detect and neutralise them.
The most common air pollutants for residential and office premises are carbon dioxide and carbon monoxide, phenol and formaldehyde, volatile organic compounds, sulphur dioxide, ozone, solid impurities, mould fungi and bacteria, dioxide and nitrogen oxide, ammonia and others.
Exceeding the allowable concentrations of these pollutants can provoke malfunctioning of the body, exacerbate chronic diseases, as well as the development of severe and irreversible diseases.
So, for example, exceeding the level of some volatile organic compounds free online journal can cause irritation to the eyes, throat, nose, and headaches, loss of coordination, nausea, liver, kidney and central nervous system damage, cancer.
Volatile organic compounds are emitted by means used in the home, office, school. These include perfumes, after shave lotion, nail polish and hair, detergents, paints and varnishes, vinegar, building materials and household goods, office equipment and many others.
Exceeding ozone concentrations will cause acute respiratory problems, worsen asthma, weaken the body’s immune system, making a person more susceptible to respiratory illnesses, including bronchitis and pneumonia.
Ozone sources are diverse, so ozone-level land is a key component of urban smog. Exhaust and industrial vehicle emissions, gasoline vapours, and chemical solvents are some of the major sources of nitrogen oxides and volatile organic compounds that help form ozone. Office products, such as copiers, computers, printers, certainly contribute to increasing the level of ozone in the premises.
A significant effect on human health is caused by formaldehyde, causing tearing of the eyes, burning of the throat and eyes, nausea and breathing problems, asthma attacks, and can cause serious allergic reactions and cancer. So the US Environmental Protection Agency USEPA considers formaldehyde a likely carcinogen for humans. This substance enters the air of premises from pressed wood and furniture made from this product, from combustion processes, tobacco smoke and so on.
To establish the causes of discomforts, fatigue, decreased productivity, increased susceptibility to respiratory diseases and access to sick leave, and prevention of serious diseases, it is necessary to conduct a comprehensive assessment of indoor air quality and the efficiency of ventilation using modern methods, equipment and attracting accredited specialists In the field of environmental assessment and control of indoor air quality, m of modern measuring equipment air quality assessment, such as GrayWolf Sensing Solutions, mycometer and other manufacturers. Only accredited specialist with experience will be able to identify the sources of pollution, categorised allocated pollutants and to develop air purification project of residential and office space, thereby to maintain and improve your health and life expectancy, increase productivity and profit.
This is only a brief overview of pollutants and their effects on the body. A more detailed examination and assessment of the impact will be disclosed in the following blocks of each substance alone.
