T. Akyuz et al., Radioisotope excited EDXRF analysis of sediment core samples from the southern part of the Black Sea, J RAD NUCL, 250(1), 2001, pp. 129-137
In all 43 sediment samples were collected as gravity cores in depth from 70
to 150 cm from the 20 sampling sites of the continental slope of the south
ern part of the Black Sea, during 1978. The samples were quantitatively ana
lyzed by radioisotope excited energy dispersive X-ray fluorescence spectrom
etry (EDXRF) using fundamental parameter technique (FTP). The investigated
sediment samples were the organic rich-mud components of the core samples,
which were known as rich in metals. The metal concentration ranges were as
follows: Ca (3.1-12.9%), Ti (1000-2000 mug/g), V (40-150 mug/g), Cr (30-200
mug/g), Mn (200-1500 mug/g), Ni (25-100 mu /g), Cu (20-70 mug/g), Zn (20-5
0 mug/g), Br (15-670 mug/g), Rb (5-90 mug/g), Sr (80-700 mug/g), Y (10-20 m
ug/g), Mo (10-111 mug/g), Zr (20-190 mug/g), Cd (<1-5 mug/g). Sb (<1-5 mug/
g), I (10-430 mug/g), Ba (100-1650 mug/g), La (5-18 mug/g), Ce (12-38 mug/g
) and Nd (6-17 mug/g). The sediment cores systematically collected in 1978
by Mineral Research and Exploration Institute of Turkey (MTA) are the oldes
t available sediment samples from the Turkish coastline of the Black Sea. T
herefore. the results may be used as references for monitoring possible fut
ure metal pollution.
