This laboratory performs analyses of pollutants affecting the environment. This includes two important areas: measuring pollutants in the work environment and analysis of waste and surface waters. The purpose of the measurement is worker health protection.
With regard to work environment pollutants, the National Institute of Public Health authorized the laboratory to perform the following measurements:
Set H6 – Sampling and evaluation of dust concentration in the work environment.
Set G8 – Measurement of noise level in the work environment C
With regard to dust, the laboratory measures weight concentration of inhalable or respirable fraction of volatile dust particles in the work environment; it identifies the level of exposure of workers exposed to such dust during the eight hour shift and comparies this level of exposure to the allowed exposure limit. The method is based on blowing air through a device equipped with a filter which captures a certain fraction of volatile dust particles in accordance with accepted conventions and gravimetric analysis is performed. Based on this calculation, the concentration for the whole shift is determined and evaluated against the allowed exposure limit.
Noise level measurement is performed at work stations by taking equivalent levels of acoustic A pressure (LAeq, T) at work stations. This is performed using a phonometer and a microphone. Based on the measured values and the worker's time sheet the total exposure to noise during a shift is calculated for an 8-hour working day (LEX, 8h).
With regard to waste and surface water analysis, the ASLAB Centre for assessing laboratory quality systems awarded the laboratory its Certificate on the correct laboratory activities.
This laboratory performs the following routine tests:
- Identification of dissolved inorganic salts
- Iron identification
- Fluoride identification
- Sulfate identification – gravimetry
- pH identification
- Conductivity identification
- NL identification
- COD (Cr) identification – titration
- Chloride identification – argentometry with potentiometric titration
- The eligibility of the laboratory to perform the above activities is verified annually by authorized persons.
