These substances in high concentrations can be dangerous and have negativ influence on the living environment. This work deals about the results of expertize condensation arose during the drying of spruce wood. Wet spruce lumber was dried by dehumidification system with low temperature conditions (55 °C). The analysis of condensate fluid (water) collected during the first part of drying process shows on a content of some volatile organic compounds. The condensed fluid was get from drying of spruce timbre of 24 mm of width. The timbre was dried in a small semi industrials scale drying kiln when the moisture of the lumber was 56% in the beginning of the process. Volume of the lumber under examination was 2.2 m<sup>3</sup>. The condensate fluid was originally from down pipe. The condensate fluid was collected during the initiatory phase of the drying, four hours after the initiation of the drying process itself. First, the value of pH of the condensate fluid was measured. Determination of volatile organic compounds was done by accredited method SOA-16. The concentration of these substances were under the limits set in the statute No. 61/2003 Law Digest.
