| description | Heavy trace metals such as arsenic, cobalt, chromium, nickel, cadmium, mercury,
selenium and lead, in addition to some micronutrients such as manganese, copper, iron and zinc
were analyzed in water, sediment, and tissues of three edible fishes (Capoeta trutta, Arabibarbus
grypus, Cyprinus carpio) and two gull species (Chroicocephalus genei and Larus michahellis)
from Derbendikhan Lake in Sulaymaniyah governorate, Kurdistan region of Iraq during winter,
spring and summer seasons. The content of heavy metals in the fish species differed depending
on the season, feeding status and sediment quality which in turn biomagnified in gull tissues. The
indices of bioaccumulation factors from water and sediment (BAFw and BAFs), bioconcentration
factor (BCF), biogeochemical index (I-geo) and pollution load index (PLI) between concentrations
of selected heavy metals in fish tissues, bird organs, sediments and water indicated that there is
direct accumulation of metals from the water and sediment to the fish and then to the higher
trophic level. Seasonal variations of heavy metal levels in water and sediment samples indicated
high levels during spring season; however, fish tissues indicated elevated concentrations during
the dry season. Sediment results for heavy metals were higher than that in water and tissues of
gull and fish species. Correlation coefficient (P < 0.05) were found between heavy metals in
sediment, fish, water and bird. The current study assumes that various metals were present in
the fish tissues at different levels, but these exceeded maximum levels permitted by WHO/FAO
particularly for lead, mercury and zinc; thus, the fish from these areas are generally unsafe for
human consumption |
