The main properties i. e., grain size distribution, contents of DCB (dithionite citrate bicarbonate extracted iron Fe(subscript d, AAO extracted iron Fe(subscript o, total Fe, DCB extracted Mn Mn(subscript d, total Mn, organic matter, magnetic susceptibility of the samples, as well as the concentrations of Cu, Zn, Pb, Cr, Cd and Ni in the samples, were determined. Basing on the data, the relation of the sediment properties to heavy metal concentrations was evaluated with pearson's rank and partial rank correlation analysis.

S where 3-EtO-SalAPA is the monoanionic Schiff base derived from 3-ethoxysalicylaldehyde and N-(3-aminopropylaziridine and S is C6H5F, C6H5Cl, C6H5Br, C6H5I or o-C6H4Cl2. Their gradual nature of spin-state interconversion is evidenced by the variable-temp. magnetic susceptibility and EPR data. Only a single quadrupole-split doublet is seen in the Moessbauer spectra for all solvates in the temperature range of
