Abstract

Today all living
creatures live in "an ocean consisting of chemicals". Therefore,
combined effects of insecticides and herbicides that frequently used together
in natural areas are important. This study aims to investigate the toxic effects
of herbicide Atrazine (ATR) with insecticides indoxacarb (IND), thiamethoxam
(THI) and endosulfan (END) mixture on Gammarus kischineffensis.

Firstly,
organisms were exposed to 1/100 LC50 value that have been determined during
96-h. We used Catalase (CAT), superoxide dismutase (SOD), glutathione reductase
(GR) glutathione S-transferase (GST) and acetylcholinesterase (AChE) activities
as biomarkers. Integrated Biomarker Response (IBR) values were calculated for
combining all assayed biochemical marker responses into one general stress
index.

Biochemical
analysis indicated that; enzymes activities in the mixture groups of atrazine
and indoxacarb reduced significantly. The combined treatment of atrazine and
thiamethoxam was caused an antagonistic effect on the biomarkers. The effect of
endosulfan and atrazine mixture caused an increase in enzyme activities.

 

This study supported by The Scientific and
Technical Research Council of Turkey (TUBITAK Proje No: 111T661) and Dicle
University Research Fund (Project no:12-FF-87)
