    Detection of Heavy Metals in Educational Institutions' Indoor Dust and Their Risks to Health
    (Mdpi, 2023) Kunt, Fatma; Turkyilmaz, Elif Sari
    In addition to human health, there are typical pollutants that significantly determine the quality of life and deteriorate the quality of the air. Although these pollutants are familiar in outdoor environments, they also pose a health threat in indoor environments. These need to be monitored and controlled. Children, who spend most of their time in these environments, are especially exposed to these pollutants, and such contaminants pose a threat during their learning and growing periods. In this study, the detection of heavy metals in indoor dust in educational institutions and their health risks were evaluated. Heavy metals such as arsenic, lead, mercury, and cadmium, which are named differently due to their densities, were detected, and their effects on children were determined. The measured values of heavy metals cadmium and arsenic were above the standard values of OSHA (Occupational Health and Safety Administration), one of the health and safety organizations. However, when educational institutions were examined, an increase in the amount of arsenic due to drinking water used, cadmium batteries containing batteries, the use of batteries, and the pigment feature in oil paint derivatives supplied with cadmium may increase the values. The other heavy metals such as Al, Zn, Hg, and Pb remained below the limit values. A health risk assessment was made by considering the data obtained from the samples taken from the educational institutions in Konya province, as well as factors such as environmental conditions, the number of students, the area per capita, temperature, and humidity. The causes of polluting sources and the precautions to be taken have been determined.
