Supplementary notes

* The atmospheric pollution index (API), used in Central Asian countries, was introduced in the USSR in 1991. It calculates "for the five substances found in the highest concentrations in relation to their degree of hazardousness. Air pollution is deemed to be very high, if the aggregate API exceeds 14; high, if 14 > API >7; relatively high, if 7 > API > 5; low, if API is < 5."
