Acute toxicity of two pesticides (organophosphorous insecticide and fungicide from sulfamid group) on Daphnia magna was studied in this experiment. Mortality of examined organisms in different concentrations of these active substances was defined. The value of lethal concentration (LC50) was calculated using probit method based on the observation results. The results have shown that after 6-hour exposure...
The paper presents the results of laboratory tests carried out in the modified soiI-geotextile penneameter (Fig. 1) recommended in ASTM standard D 5101-90. Laboratory tests were performed on nonwoven geotextile K-500 (Tab. 1) and slightly clayey sand (Tab. 2). In figures 2 and 3 the change in permeability coefficient in soil-geotextile system for individual zones under different hydraulic gradients...
