Apstrakt:
Fish consumption, especially consumption of oily marine species, is globally
increasing since it has been recommended by dieticians due to high content
of polyunsaturated ω-3 and ω-6 (PUFAs) fatty acids in fish tissue. Health
benefits of PUFA ingestion coincide with the risk of intake of hazardous
lipophilic persistent pollutants including organochlorine pesticides (OCPs)
and related polychlorinated biphenyls (PCBs). We examined the impacts of
18 fatty acids (FAs) and 36 toxic organic and inorganic contaminants on the
behavior patterns of indicator congener PCB-138 in marine fish using eXtreme
Gradient Boosting (XGBoost), SHapley Additive exPlanations (SHAP), and
SHAP value fuzzy clustering. XGBoost indicated non-linear relationships
between investigated variables that surpasses indications suggested by commonly
applied correlation matrices. Ten extracted fuzzy clusters of SHAP
values revealed that higher intake of saturated myristic-C14:0 and margaric-
C17:0 acids followed by intake of nutritionally beneficial eicosadienoic acid
(C20:2n-6) mostly contributed to the PCB-138 bioaccumulation. Important
impacts on PCB-138 behavior patterns were also registered for chemically
allied indicator congeners (-153 and -180) and organochlorines’ metabolite
p,p’-DDE. Less prominent were the associations between target congener
and the most toxic dioxin-like PCBs.
