We contacted Uzhydromet; they responded immediately and gave us the data. We made a written request and received a written response. We gave this data to Pavel; he prepared graphs for all countries. Later, Pavel said that he would use data from the https://aqicn.org/
website; he trusts it more. Another source of information for us was a family from Almalyk: a son and a mother who suffer from respiratory diseases and attribute their diseases to polluted air. We also tried to talk to representatives of an environmental movement, but we did not get to the point of requesting data: they assured us right away that there were no problems in the city, and we did not argue with them. An employee of the AMMC (Almalyk Mining and Metallurgical Complex, a city-forming enterprise) claimed that they had everything thought through, that work was underway, that new filters were installed in production, and everything was being done to improve the situation. We also had information that the filters installed at the factory delay the production process and consume energy, so they are often simply not turned on, unless there are inspections coming. We did not have a source to confirm this information, so of course we could not include it in the material.
