**4. Conclusion**

In conclusion, the production of feedstuff, both naturally and from industrial by-products, for use in animal husbandry, poses the risk of exposure to PAHs. This risk points out to the need for conducting PAH analyses in feedstuff used for the production of animal products, which have an important place in the food chain of humans. It is evident that the number of available studies on the impact of PAHs on the environment and animal health is rather limited [12, 18, 36]. In this context, it is considered that determining the impact of PAHs on human nutrition and health by fully demonstrating the adverse effects of PAHs on animal nutrition and health, as well as developing remediation strategies, is of utmost importance.
