ABSTRACT
Surface and bottOlll aea water s..,lea were collected frOlll
the elatern Hlrbour during the period frOlll May 1987 to May
1988. Detergenta, salinity, totll phosphorus and
polyphoaphatea coccentrltlona were dete~fned. Average
aurflce content. of detergents at the surface was 0.92 Mg
eq. LAI/l and It the bottOlll waa 0.43 Ill9 eq. LAS/l. Tile
frequency distribution of anionic detergenta showed thlt 68″
of the analysed s~les l fea in the range of 0.0-0.8 IlI9 eq.
LAS/l. Totll phosphorus average concentration It the surflce
WIS 3.76 umol/l end at the bottom wc~ 2.1 umol/l and
polyphosphates content It the surface was 2.96 umol/l and It
the bottom wal 1.45 umol/l. Salinity concentration It the
surface was 35.85″0 whill It the bottom was 38.2″0 In June
and July 1987 a significantly high negltlve correlation
exists between booth sllinity and detergents, total
pgosphorus Ind pol yphosp,otel. On the other hand detergents
show high positive correlltion with total phosphorus and
polyphosphates In the aame period. we aimed to atudy the
distribution of Mionfc detergenta In the Harbour and Its
effects on th!’! tota l phosphorus content.
