Abstract:
Atrazine (2-chloro-4-ethy- lamino-6-ethylamino-1,3,5-triazine) is the commonly used pesticide in agriculture for pest control. It is the most used synthetic and toxic triazine herbicide in the world and is applied against the emergent weeds in maize, sorghum, sugarcane, and fruit crops. It was initially introduced in the 20th century and is frequently combined with other herbicides or used alone in agricultural applications. Atrazine pesticide was detected in replicate in water, sediments, and fish from three sites of River Indus including Attock (S1)reference site, Khushal Garh (S2) Medium site, and Chashma Barrage (S3) heavy polluted site receiving agricultural runoff from nearby agricultural fields around the River Indus. The samples from all the three sites of River Indus were analysed for Atrazine pesticide by using High performance liquid chromatography (HPLC). The results of the assessment of ATZ revealed the widespread occurrence of atrazine in the River Indus ecosystem. Elevated concentrations of atrazine were detected in both water and sediment samples, indicating a significant contamination of the river Indus. Fish samples from different species were analysed for atrazine residues to evaluate the potential bioaccumulation and biomagnification of the herbicide in the aquatic food chain. The findings indicated the presence of atrazine residues in fish tissues. The results indicated that the measured concentrations of atrazine in the River Indus exceeded the recommended limits set by FAO and WHO, suggesting a potential detrimental impact on aquatic organisms and ecosystems. In conclusion, this study highlights the significant presence of atrazine in the water, sediment, and fish of the River Indus, emphasizing the urgent need for effective management strategies to mitigate the potential ecological and health risks associated with this herbicide.
