Abstract

Remediation and management of dumpsites is a worldwide problem that must be addressed to protect human health and the environment. Aragon Government long-term objective is the control of air quality related to landfills used to dump organochlorine waste. The present study evaluated the influence of dismantling works performed in Bailín landfill, an hexachlorocyclohexane (1,2,3,4,5,6-hexaclorohexane; HCH) dumpsite located in the city of Sabiñánigo, Spain. A total of 65,000 t of HCH solid waste and 342,000 t of polluted soil were transferred to a new cell with additional isolating measures going beyond the Spanish legal requirements. To evaluate influence of excavation of the old cell, transfer of waste and the state once the works in Bailín area had finished, levels of α-, β-, γ-, δ- and ɛ- HCH isomers were analyzed in 112 air samples obtained from summer 2014 to autumn 2016 by using passive air samplers. Results showed that: i) the existence of the old landfill and/or the works performed during its dismantling were a source of HCH air contamination, ii) old landfill represented an HCH source even after dismantling work was completed, iii) other sources, tentatively associated to Sardas dumpsite and HCH production site (INQUINOSA Factory) were identified in the surroundings, where management should be addressed. Data comparison reflected a heavier contamination caused by the production, storage, and waste disposal than the corresponding to application of lindane and/or technical HCH in Spain. Meteorological dependence (temperature, solar radiation and relative humidity), α-/γ-HCH ratios and isomer profiles of HCH air concentrations were evaluated for temporal trends and geographic distribution.
