Hi Tatyana,

Good job.

This is pretty complicated text so it can be pretty challenging to write.

Just a few corrections:

Translation

We can buy pure water and good-quality food. (But) We can't buy clean air. Polluted air easily crosses borders, companies, towns and countries, and penetrates into the offices, homes and hospitals. Therefore, we can only welcome the work of the WHO Regional Office, that solves the problem of providing good air quality. One of the important activities in this area is monitoring of the air. Quite naturally, the main task of monitoring is the acquisition (or accumulation, or generation) of such information about air quality , which will allow to estimate its influence on peoples health, that in turn, provides more reliable information base for implementing and control of the effectiveness of appropriate management decisions.
