Impact of closed Kairiai landfill on the Ginkūnai Pond, Lithuania

Abstract

The main goal of this study was to investigate the impact of the closed Kairiai municipal landfill located near Šiauliai City on the Ginkūnai Pond, into which the leachate from the landfill is released. The main aim of our study was to determine the phytotoxic impact of landfill leachate, water and bottom sediments of the Ginkūnai Pond and Švedė Creek, as well as drainage channel through which the leachate is discharged into the pond. The main characteristics of physico-chemical analysis of the leachate, water and bottom sediments of ecosystem tested were assessed. The amount of chlorophyll "a" and dominant groups of phototrophic organisms were also investigated. The tests were performed during 2012 and 2013. Phytotoxicity tests were carried out using seed germination and root growth test of Lepidium sativum and relative growth rate (RGR), biomass, and amount of total chlorophyll of Lemna minor. The leachate was very toxic to both tested plants. The water of the Ginkūnai Pond was moderately toxic for root growth of L. sativum and in many cases non-toxic or slightly toxic to L. minor. Investigations of the impact of Kairiai landfill on the Ginkūnai Pond confirmed the expected existence of the gradient of the usually measured physic-chemical parameters in water of the receiving pond. A strong trend of the decrease of chlorophyll "a" content across the pond was revealed. However, the data of phytotoxicity tests did not show similar tendency. Phytotoxicity testing and physico-chemical investigation showed that the closed Kairiai landfill is still remains a serious source of long-lasting permanent pollution, which affects the neighboring water bodies.

Wastewater and Landfill Leachate Testing: Acute Toxicity Biotest Results Evaluation

“…The landfills could remain a permanent pollution sources for long periods of time after closing (Pablos et al 2011;Klauck et al 2013). For example, physico-chemical investigation, phytotoxicity testing and use of battery of biotests (leech, crustacean and fish) showed that the Kairiai landfill closed in 2007 remains a serious source of long-lasting pollution, which adversely affects the neighboring water bodies (Svecevičius et al 2013;Montvydienė et al 2014). Such problems can be potentially even worse when leachates are percolating into trans-boundary Rivers (i.e.…”

“…Ecotoxicological reseach of toxicants, WW and ll in lithuania. Ecotoxicity investigations of various individual toxicants or their mixtures, WW, LLs were undertaken with standard aquatic organisms of different phylogenetic levels (bacterium, crustacean, algae, fish (četkauskaitė, Bražėnaitė 2004;Kalcienė, četkauskaitė 2007); and ontogenetic stages (fish embryos, larvae, adults) (Kazlauskienė, Vosylienė 2008;Svecevičius 2006;Vosylienė et al 2010;Svecevičius, Kazlauskienė 2011;Montvydienė et al 2014). Chemical analysis and biotest battery data based ecotoxicological evaluations of municipal WW from regional WW treatment plants of Lithuania cities were implemented in 2007 and 2010 (Manusadžianas et al 2010;COHIBA 2012).…”
