Mean conductivity values are based on 16 different measurements between March 1999 and November 2000.
Numbers of culturable hydrocarbon degraders (MPN per gram of soil as determined in Bushnell-Haas medium with hexadecane as the sole carbon source) are expressed as fractions of the numbers of total culturable heterotrophs (MPN per gram of soil as determined in 10% TSB medium) calculated as the means of data collected in five different months in the year 2000.
