**4. Conclusion**

Ergene River Basin surroundings were selected for this study: one heavily contaminated sites, moderately contaminated sites, and one less contaminated reference sites. The modified QuEChERS method used in this study was practical for mixtures found in environmental samples. This technique performs well, exhibiting good sensitivity, selectivity, and precision in the range of concentrations appropriate for the determination of target analytes. Our study investigated to the Ergene River Basin in sediment, rice, rice husk and water were analyzed for trace organic pollutants. However, the sediment and plant (rice and husk) had measurable and sometimes high levels of PAHs, even though no industrial sources of pollution were known. Other sources of PAH contamination may include runoff from paved roads and exhaust from farm machinery, and factory wastes immediate of the sampling stations. Therefore, in the alives feeding with husk of rice, there may be bioaccumulation of EN and PAHs. Ecological risk assessments for the sediment efficacies concluded that response actions were necessary for the sediment and husk, except for water and rice.
