Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:
- Particulate matter (PM) Levels
- Sulphur oxides (SOx)
- Nitrogen oxides (NOx)
- Volatile organic compounds (VOCs)
- Carbon monoxide (CO)
- Updated on at least once a week.
- Measured either at a national level by regions or at leasts in 3 big cities.
No data is available online for air pollution but it seem the data is Measured -no pm data Exist so the data is Considered non-existent http://www.unece.org/fileadmin/DAM/env/epr/epr_studies/kazakhstan.pdf
The four basic pollutants (SO2, CO, NO2 and dust) are monitored, as are some site-specific pollutants such as heavy metals, HF, HCl, NH3, arsine, phenol, formaldehyde and chlorine. There are no ground-level ozone monitoring data available. Data on lead and other heavy metals as well as benzo(a)pyrene, which were monitored regularly in the past, are scarce at present. No information on PM 10 or PM 2.5 is available. Air quality is assessed according to the so-called IZA5 indexes, which record the exceeding of maximum permissible concentrations (MPCs) of five representative pollutants, together with their toxicity classes. The air is considered polluted, if this index is higher than 5. As shown in table 4.6, air quality has improved slightly in recent years, but still needs to be improved in most cities. Moreover, due to a lack of money monitoring has suffered some inconsistency over the past years, reducing the number of monitoring sites as well as the number of monitored pollutants. The indexes are therefore not always calculated from the same set of pollutants, and this may result in inconsistency. For example, if in Almaty benzo(a)pyrene, also in the highest toxicity class, was included in calculations of the IZA5 index, it would amount to 54. When benzo(a)pyrene was no longer measured, the value of the index fell, but this does not necessarily mean that air quality in fact improved.
checked its seem that Originally the The criticism is of incorrect information Pollution What was originally written There are datasets about level of pollution of settlements, radiation state of surface air, the density of radioactive fallout in the surface layer of the atmosphere, changes of complex index of water pollution in the rivers, reserviours, lakes and canals. The information provided by government officials in Kazakhstan (by default) is open for reuse, publishing as cited by the law.
