Seasonal Changes and Toxic Potency of Landfill Leachate for White Mustard (Sinapis alba L.)

Abstract

Landfills are the most broadly used methods for the disposal of municipal solid waste (MSW). Leachate can be contaminated with pollutants that may pose a threat to the landfill surrounding namely soil, groundwater and surface waters.. Examination of leachate composition is determinative in long-term impact of landfills on the environment and human health. Moreover, it is essential to assess such prior knowledge for prevention of negative outcomes. The evaluation of the seasonal changes of landfill leachate and rainwater composition is presented in this paper. Research samples of leachate and rainwater were collected from February till June of 2017 (still ongoing) and analyzed for pH, electrical conductivity, dissolved oxygen, series of trace elements, Subsequently the test of leachate toxicity for higher plants (Sinapis alba L.) was carried out. Up to now, the results do not indicate significant seasonal difference in landfill leachate composition, however the toxicity tests provided on Sinapis alba L. demonstrate that landfill leachates can present a significant source of contamination. This research can serve practical tools for evaluating quality and risk assessment for landfill leachate.

Chemical Composition and Hazardous Effects of Leachate from the Active Municipal Solid Waste Landfill Surrounded by Farmlands

“…The effect of leachate on higher plants (Sinapis alba L. and Cannabis sativa L.) was studied by Zloch et al [14,18]. Phytotoxicity tests of concentrated leachate confirmed a GI higher than 90% (Sinapis alba L.).…”

“…It follows that toxicological research focused on the synergic effects of pollutants contained in leachates is necessary [17]. Since the leachates from MSW landfills are characterized by various compositions, biological tests are becoming more popular in determining their toxicity [12][13][14]18]. A test of leachate toxicity for higher plants was carried out by Zloch et al [14,18].…”

Kalčíková et al [19] consider that Sinapis alba L. belongs to sensitive species and is often used to test toxicity.…”

Biodegradation/Disintegration of Selected Range of Polymers: Impact on the Compost Quality

“…The plants grow rapidly and enter a phase of dense flowering in early summer, reaching their full height of 1.5 to 2 metres as their flowers fade and the fruits appear. Sinapis alba L. is sensitive to chemicals so it is suitable for toxicity tests [23] and is ideal for studying soil/ compost and soil/compost extracts [24,25].…”
