Samples of dust collected from the interiors of 45 buildings in all city districts of Prague are being analyzed in cooperation with the University of Chemistry and Technology in Prague. This unique research, which included 26 households as well as public buildings (including the Senate of the Czech Republic and the Prague City Hall), offices, printing works or a dental laboratory, is carried out within the project “Rtuť, arsen, olovo a kadmium – nebezpečné kovy v životním prostředí Prahy” (mercury, arsenic, lead and cadmium – hazardous metals in the environment of Prague) funded by the city of Prague.
The results will form the basis of a study that is supposed to clarify whether indoor dust reflects the quality of the external environment in a given location, whether there are any differences between individual city districts or in the vicinity of potential sources of pollution, or whether indoor furnishings are the main factor. The project aims to raise public awareness of the harmfulness of heavy metals to human health and the need to avoid such substances. The results of the research of interior dust will be compared to the map of the outside air quality regularly created by the Czech Hydrometeorological Institute and we will find out the extent to which external pollution coincides with the pollution of the examined interiors.
The results of the research will be published during autumn 2017. Arnika will introduce them to the general public as well as experts and state administration. Before Christmas, all participants will be invited to a round table to discuss the conclusions of the research and propose measures that people or government authorities should take to avoid the occurrence of heavy metals at home or at work. The measurement results will be anonymous so as not to harm private establishments or child facilities. You can learn about the dust sampling here.
