Abstract

In this study have
been investigated the effects of heavy metals on foraminiferal assemblages in
Çanakkale Strait. For this purpose, core samples were collected from 12
locations in the Çanakkale Strait. With the consideration of the faunal and
sedimentological properties of the samples have been showed that the Çanakkale
Strait is completely has rich marine foraminifer populations. The abnormalities
observed of foraminifer the yellow and/or black colored shells have been due to
natural and anthropogenic ecological pollution. In the present study the
pollution index (PI) values were calculated to bring to light the heavy metal
pollution.

 

Especially in the
ports, Morphological abnormalities and the color changes have been seen at
shales of benthic foraminifer genera and species. Morphological changes were
observed in Elphidium crispum, Massilina secans, and Ammonia compacta
foraminifer species in the core samples taken in areas where  ports in the Çanakkale Strait. Especially
Morphological changes were observed in Elphidium crispum, Massilina secans, and
Ammonia compacta foraminifer species in the core samples taken in areas
where  ports in the Çanakkale Strait. The
pollution index (PI) value measured in Ports have been higher than the critical
value, indicating that heavy metal concentrations affect the foraminifera.
