Contamination of bank sediments near historic glass works in the Bohemian Forest, Czech Republic

Original language description

Basic characteristics (texture, dry bulk density, pH(H2O) and pH(CaCl2), total C and N contents) and the vertical distribution 46 element contents were determined at 5 cm intervals in vertical bank sediment profiles from 9 pits dug along the Teplá Vltava and Řasnice Rivers, in order to uncover potentially archived contamination from the operation of a former (1834–1995) glass works in Lenora. Ample amounts of charcoal fragments buried in the sediments of two pits had 14C ages between 1250 and 1445 BP. Charcoal affected the bulk density and content of elements in fine earth. The contents of the anthropophile elements As, Bi, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, S, Sb, Se, Sn, V and Zn, the thickness of the contaminated topsoil layers and the element content gradients in sediment profiles decreased with the distance of pits from the former glass works. The sediment topsoil was most heavily contaminated by Cd, Hg, Pb, Sb and Sn, especially near the former glass works. Most of the As in sediments from the pit near Borová Lada was of geogenic origin. Surprisingly, sediment pollution by Pb near the glass works was lower than expected. However, the 206Pb/207Pb ratio increased with the depth of sediments, indicating an anthropogenic origin of Pb in the topsoil. The geoaccumulation indices (Igeo) of elements mainly in the topsoil were highest for As, Cd, Hg, Pb, S, Sb and Sr, while enrichment factors (EF) were highest for As, Be, Bi, Cd, Hg, Mo, Pb, S, Sb, Sn, Ti, W and Zn. Increased contents of especially lithophile elements in the flood sediment layers exceeding local background element levels were caused by the accumulation of weathering products of local granites and other bedrocks rich in these elements. Contents of 8 potentially toxic elements (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) in the topsoil and in the whole sediment profiles near the glass works represent moderate to severe potential ecological risks. Cd, Hg and As, with the highest toxicological effects, contributed most to the total potential ecological risk. However, contributions to the total ecological risk from other elements with biological impacts (e.g., Be, Sb, Sn, Th, Tl, etc.) could not be estimated due to the unknown toxic response levels of biota.
