Abstract

The municipal solid waste of coal combustion is one of the main environmental problems in Ulaanbaatar, especially in the area of "Ger" districts due to lack of heating system and no waste management [D. Altantuya et al., 2012 and B.Byamba et al., 2017 and Delgermaa et al 2016]. The coal ash is disposed of in wintertime from each household in ger districts which contains approximately 49% of waste disposes of Ulaanbaatar [Ulaanbaatar Waste Management Improvement Strategy and Action plan]. Our previous study assessed the human health risks of heavy metals in soil on the ger districts of Ulaanbaatar [B. Enkhchimeg et al, 2020]. The results showed that elements of Cr and As were ranged the risk for human health from soil near their street in ravine and waste points. Those elements in coal were ranged to possible to transition for the human body by three pathways. Therefore, to protect the environment and public health of those living in the Ger area, the risk management study should be performed. This study is continuing our previous study that was necessary to consider the risk communication of environment and human health issues on coal ash and coal usage at ger residents due to there is no research related to the risk communication between coal usage and residents in Ger district of Ulaanbaatar city. According to our objectives, the subjects determined how the expose from coal usage through three pathways based on the questionnaire survey.
