The Effect of Various Types of Norway Spruce Woodchips on Aquatic Organisms
Original language description
Wood and woodchips are widespread materials with different uses, but their ecotoxicity is not yet sufficiently examined. Branches of Norway spruce collected in Hostouň (Czech Republic) were separated into bare and needle-leaved branches and chipped in two ways: as rough chips and as fine chips. Besides, samples of needles, chipped cones, and a mixture of all parts were also prepared. Water leachates made from the samples were tested for their ecotoxic effect in duckweed and freshwater algae. Microscopic fungi and yeasts, conductivity, and pH were measured in the leachates. Concentrations of selected elements were subsequently determined by atomic absorption spectroscopy. Phenolic compounds were identified through high-performance liquid chromatography. The fine chips produced more toxicity to the model organisms than rough chips. Samples containing cones had the highest negative impact, whereas needles showed only low toxicity. These results indicate the necessity of ecotoxicological testing of woodchips prior to their use in practice. The level of toxicity seems to correlate with the content of phenolic compounds and the variety of microorganisms present in the wood, but further research is necessary.
