Bottom-sediment cores were used to investigate the occurrence of 44 metals and trace elements, and 15 organochlorine compounds in Tuttle Creek Lake, a reservoir with an agricultural basin in northeast Kansas, U.S.A. On the basis of U.S. Environmental Protection Agency sediment-quality guidelines, concentrations of Ag, As, Cr, Cu, Ni, and Zn frequently ...

Separation of organic compounds binding trace elements in seeds of Leuzea carthamoides (Willd.) DC
Applied Organometallic Chemistry, 2004AbstractThe distribution of trace elements into important groups of compounds in seeds was investigated using a seven‐step sequential extraction of seed biomass (solvents used: petroleum ether, ethyl acetate, butanol, methanol, methanol + H2O (1 + 1; v/v), H2O, methanol + H2O + HCl (49.3 + 49.3 + 1.4; v/v/v)).

The atmospheric aerosol is an important pathway by which chemical compounds are transported both locally and on a global scale. It is extremely important to know the origin, geochemical composition and effects that the aerosol composition could have on a very sensitive environment such as the Arctic.

The importance of knowledge about the chemical nature and the concentrations of trace element compounds in environmental samples is now widely recognized. Methods are available to identify and determine trace element compounds that are kinetically stable under the conditions imposed by the analytical procedure.
