Laboratory`s measurements:

  • work enviroment noise measurements;
  • working environment vibration measurements;
  • environmental and building structures vibration measurements;
  • measurements of electromagnetic field.

  • Chemical risk factors:

  • lead, mercury, manganese, zinc and other metals;
  • phenol, formaldehyde, xylene, toluene, benzene, tetrachlorethylene, solvents and other organic compounds;
  • various types of dust (sugar, flour, wood, metals, textiles and others);
  • carbon monoxide, nitrogen and sulfur dioxide, ozone and other chemical compounds;
  • lighting (general, localized-general, local,combined);
  • microclimate (relative air humidity, temperature, air velocity).

  • Pollutant emissions measurements:

  • soligs concentration and mass flow determination in the discharges;
  • inventorisation of source of emissions and gas treatment plant passportisation;
  • pollutant emissions testing, including the different capacity of boiler houses (oxygen, carbon dioxide, carbon monoxide, nitrogen oxides and sulfur dioxide by express method);
  • measurements of the gas flow physical parameters, adjustment of ventilation system and passportisation (as for the new ventilation systems before is input into operation, as well as to existing systems).

  • Water analysis:

  • chemical: alkalinity, hardness,permanganate index, calcium, magnesium,iron, manganese, ammonium ions, nitrate, nitrite, chloride, sulphate, dry extract;;
  • electrochemical: pH and electrical conductivity;
  • organoleptic: odor, taste, color, turbidity.

  • In the wastewater are analyzed:

  • effect of environmental pH;
  • chemical oxygen demand (COD) and biochemical oxygen demand (BOD);
  • suspended matter;
  • grease and oil products;synthetic surfactants;
  • ammonium, nitrate, nitrite and total nitrogen;
  • phosphates and total phosphorus;
  • index of phenols and formaldehyde.
  • LLC "R & S TET" composed the work environment Control Laboratory (accredited by the Latvian National Accreditation Bureau and is competent to perform testing in accordance with LVS EN ISO / IEC 17025: 2005 standard requirements in the following areas: the working area air and physical factors testing (LATAK registration number LATAK-T-421-05-2010-A)).
