Abstract [en]

More than 34 old glasswork sites in the southeastern part of Sweden pose a permanent threat to human and environmental health due to the presence of toxic metals in open dumps with glass waste. The possibility of leaching of metals from different fractions of the disposed waste needed to be assessed. In the present investigation, leachate from fine fraction (soil plus glass particles < 2 mm) was characterized as following: pH (7.3), TOC (< 2%), organic content (4.4%), moisture content (9.7), COD (163 mg/kg) and trace elements content, being the values in accordance to the Swedish guidelines for landfilling of inert materials. However, very high metals content was found in the fine fraction as well as in all colors of the glass fraction (≥ 2 mm), whose values were compatible to hazardous waste landfill class. Tests with Lepidium sativum growing in the fine fraction as substrate revealed chronic toxicity expressed as inhibition of root biomass growth in 11 out of 15 samples. Additionally, leachate from fine fractions posed acute toxicity to genetically modified E. coli (Toxi-Chromotest). This study highlights the importance of combining physicochemical characterization with toxicity tests for both solid waste and leachate obtained from different waste fractions for proper hazardousness assessment supporting decision making on remediation demands.
