Assessing the effect of irrigation with landfill-rainwater some higher plants

Popis výsledku v původním jazyce

Landfilling of municipal solid waste (MSW) and waste handling in the landfill may be risk of pollution to the environment. Rainwater which does not fall into the open landfill body should not be contaminated with pollutants from waste and therefore, it is stored in a separate rainwater pond. There is however a risk that the precipitation water will come into contact with contaminants, which might occur on the landfill site (handling surfaces, access roads etc.). The pond is isolated from the surrounding environment by the HDPE foil. Because water from the rainwater pond can be used for watering e.g. the poplar plantation in the landfill site, it is necessary to evaluate its possible toxicity. This study focuses on the assessment of landfill rainwater effects on plant material. Phytotoxicity was assessed in modified semichronic tests with the seeds of hemp (Cannabis sativa L.) and white mustard (Sinapis alba L.) Vital seeds were cultivated on Petri dishes in laboratory conditions in the solution of landfill rainwater at various concentrations. Inhibition or stimulation of root growth was evaluated through calculation and comparison of seed root lengths from reference samples and tested samples. The tests demonstrated higher susceptibility of Sinapis alba L. to contamination as compared with Cannabis sativa L. The lowest value of mustard seed inhibition was recorded in March at a concentration of 20%. Values of inhibition were high in all tests with Sinapis alba L. (up to 89.5%). Inhibition in Cannabis sativa L. seeds from September, October and November was high. The tests with the use of Sinapis alba L. did not show any stimulation of root growth. In some cases, Cannabis sativa L. could resist the toxic influence of water samples and it was recorded growth stimulation of up to 33.2%. Results of the tests of landfill rainwater toxicity were fluctuating and pointing to the contamination of this water.
