Abstract The inputs of As in forest ecosystems have declined since the eighties when higher concentrations that metalloid were observed due to industrial activities. floor include throughfall and litterfall where dry deposition is an appreciable percentage. This manifested by concentration older needles conifers enrichment relative bulk deposition. convert inorganic into methylated organic this...

This study detected eight heavy metal (Cu, Pb, Zn, Ni, Mn, Fe, Cr, Al) and one metalloid (As) amounts in the sediment of Meyil Lake. The findings obtained were compared with limit values quality guidelines (SQGs) such as PEL (probable effect level), TEL (threshold ERL (effects range low) ERM median). In addition its probable toxic effects investigated via different evaluation methods. As a resu...
