Arsenic and mercury bioaccumulation in the aquatic plant, Vallisneria neotropicalis.

Arsenic (As) and mercury (Hg) are among the most toxic metals/metalloids. The overall goal of this study was to investigate the bioaccumulation of these trace elements in Vallisneria neotropicalis, a key trophic species in aquatic environments. For this purpose, As and Hg concentrations were determined in sediments and natural populations of V. neotropicalis in sub-estuaries of Mobile Bay (Alab...

Role of photochemical reactions in the biogeochemical cycling of detrital carbon in aquatic environments

Cover figure: Atomic force microscopic image of <0.1 µm filtered water of Lake Valkea-Kotinen sampled on 6 August 1996 displaying detrital and/or viral particles. Fifty µl of the filtered water was allowed to evaporate to dryness on a crystal of mica (diameter of 1 cm). The image was taken with a multi mode atomic force microscope by the courtesy of dr. S.
