ndocrine disrupting chemicals (EDCs) are of global concern
and find their way to the marine environment via the
sewage treatment plants (STPs). Dumping untreated sewage to
the coastal areas is one of the critical stressors to Kuwait marine
environment, which can deteriorate the quality of seawater and
sediment. This study was designed to investigate the status and
sources of EDCs and their effect on fish in Kuwait’s coastal areas.
The analysis of field samples from exposure sites revealed
significant levels of EDCs in seawater (phthalates: 2.1 to 4.6 µg/l;
alkylphenols: 1.2 to 16.4 ng/l; estrogens: 0 to 36.2 ng/l) which
clearly indicated a local source or chronic input of untreated or
partially treated water. Sediment samples showed significant
levels of the three main classes of EDCs (phthalates: 2.1 to 15.7
mg/kg drywt; alkylphenols: 2.5 to15.1µg/kg drywt.; estrogens:
4.1 to 214.2 µg/kg dry wt.) which indicated a possible release
from sediment which acts as a reservoir for pollutants. Yellow-
finned seabream (
Acanthopagrus latus
) were placed in cages
and exposed near sewage discharge areas for two weeks. Fish
liver were dissected for histology and immunohistochemistry
and the results revealed hepatic alteration in fish liver samples
in the form of hepatic depositions and necrotic changes
although no marked deviation in the structural integrity of the
hepatic tissue was observed. Vitellogenin (Vtg) localization was
also detected in liver samples correlated with the EDCs levels
in seawater and sediment samples. The existing levels detected
in Kuwait marine environment posed a physiological effect on
fish and Kuwait Bay is very important and sensitive ecological
system which should be protected from all kinds of stressors
especially the anthropogenic.
