The effects of dioctyl adipate (DOA) on the gill histology of labidochromis caeruleus fryer,1956 (Cichlidae,Teleostei) [dioktil adipat'i{dotless}n (doa) labidochromis caeruleus'un fryer,1956 (Cichlidae,Teleostei) solungaç histolojisi üzerine etkileri]

Although it is used widely as a second plasticizer in processing polyvinyl and other polymers,the data about the ecotoxicological effects of dioctyl adipate (doa) is limited. in order to investigate the primer effects of short term sublethal exposure to doa on the gills of labidochromis caeruleus (yellow princess),the specimens were divided into three groups included two control and one experimental group. after a period of 30-days,the tissues were removed for histological examination. when compared to the untreated and 2.5 ppm acetone exposed controls,the gills of the experimental animals that exposed to 0.75 ppm doa showed remarkable histopathological changes distinguished as hypertropy,severe hyperplasia,aneurysma,oedema,epithelial lifting,and striking fusion. the results indicate that doa would have to take into more consideration as an ecotoxicant.
