    Wpływ zanieczyszczenia gleby różnymi związkami rtęci na aktywność mikrobiologiczną gleby
    (Wydawnictwa AGH, 2005) Florencka, Natalia; Chmiel, Maria
    Presented paper concern studies on influence of soil contamination by mercury compounds $(HgCt_{2}$ $HgO$, $Hg(NO_{3})_{2})$ in five different doses (0,1. 0,5. 1,0. 5,0. 10,0 mg/kg) on number of vegetative and resting stages of mesophilic bacteria, Azotobacter genus, the number of Actinomycetes and microfungi. The results of laboratory investigations displayed the mean reduction of vegetative stages of mesophilic bacteria on sites with mercury oxide $(HgO)$ already in lowest dose - 0,1 mg/kg and the Actinomycetes number on sites with doses over 0,5 mg/kg $Hg(NO_{3})_{2}$. $HgCl_{2}$ (corrosive sublimate) was the most toxic compound to Azotobacter sp. Filamentous fungi were the most resistant group of soil microorganisms.
