UNLABELLED BACKGROUND, GOAL AND SCOPE: Cleaner CRYSTAL Simple Green (SG) was used for the cleanup of the oil spill in the Baltic Sea near Lithuania in 2001. No scientific data are available on the effects and consequences of its application for local aquatic life. The aim of this study was to determine and compare sublethal effects of a) solution SG; b)(More)
Semi-static acute toxicity tests were conducted on adult roach, Rutilus rutilus, to estimate its sensitivity toward an equitoxic binary mixture (EBM) of copper and nickel. The sum of their individual LC50 values was considered to equal 100 %. The main endpoints of the study were mortality and behavioral responses: detection, locomotor activity, coughing(More)
Laboratory tests were conducted on higher plants [garden cress (Lepidium sativum), great duckweed (Spirodela polyrrhiza), and Tradescantia clone BNL 02] and fish [rainbow trout (Oncorhynchus mykiss) at all stages of development: eggs, larvae and adults] to estimate their sensitivity to heavy fuel oil (HFO). A number of biological indices (survival, growth,(More)
Experimental studies of infection transmission via water from infected to healthy fish were conducted. The dark-brown bacterial colonies typical for Aeromonas salmonicida on tryptone soya agar (TSA) have been isolated and counted (from 3.0±0.6×102 to 3.5±0.5×105 c.f.u. g−1) from the internal organs of naturally infected (NI) and experimentally infected (EI)(More)
The effects of a model mixture (HMMM) of seven heavy metals (Cu, Zn, Ni, Cr, Pb, Cd, Mn) on the rainbow trout Oncorhynchus mykiss at all stages of development (embryos, larvae, adults) were investigated based on the annual average concentrations of these metals in cooling waste waters discharging from Ignalina Nuclear Power Plant (Lithuania) into the(More)
GOAL, SCOPE AND BACKGROUND Orimulsion (stable emulsion of natural bitumen and water) is a new imported industrial fuel in Lithuania. No data on its toxicity to fish is freely available. The aim of this study was to investigate sensitivity of rainbow trout (Oncorhynchus mykiss) to acute and chronic toxicity of orimulsion and to estimate the Maximum(More)
The toxicity and genotoxicity of untreated raw (RWW) and treated wastewaters (TWW) samples from Vilnius wastewater treatment plant was assessed using fish (rainbow trout) at different stages of development. The survival of larvae and fish exposed to RWW in short-term and longterm tests reduced, whereas gill ventilation frequency, heart rate and relative(More)
