Importance of fish gender as a factor in environmental monitoring of mercury
Original language description
Total mercury concentrations were determined in the gonadal tissues of 15 female and 10 male European perch (P. fluviatilis) from one location of the stream ?Jevanský potok? located about 30 km from Prague (Czech Republic). Tissue samples were frozen at-26°C in polypropylene containers until further processing, which was carried out using an Advance Mercury Analyser (single purpose atomic absorption spectrometer). Mercury concentrations were present in all analysed gonad samples, and ranged from 2.3 to12.7 ?g/kg wet weight. However, we determined a mean Hg concentration (9.45 ?g/kg) in male gonads that was 2.4 times greater than that of female gonads (3.9 ?g/kg). This is important finding when taking into account fish sex in environmental pollution monitoring (especially for mercury contamination).
