Methodology of PAHs and threshold dynamics research in oilseed‑based food chains.
This research focuses on methodology and systematic monitoring of agroecosystems, with particular attention to xenobiotics in lipid‑containing plant products. Polycyclic aromatic hydrocarbons (PAHs), as lipophilic contaminants, pose carcinogenic risks to food chains when their gradual accumulation reaches and exceeds critical sanitary‑hygienic thresholds. One of the tasks of the research was to develop a methodology for identifying and studying threshold dynamics, gradual accumulation of contaminants may remain undetected until a critical point is reached, shifting ecological safety. A validated chromatographic methodology allowed the detection of trace amounts of PAHs in sunflower and flax seeds, as well as in vegetable oils. This provides early warning signals for the food safety system. Grounding on Codex Alimentarius and sectoral sanitary standards norms, we can see the practical importance of experimental monitoring. Systematic monitoring makes it possible to capture both linear accumulation and abrupt (jump‑like) threshold transitions across the stages of cultivation, storage, and processing of oilseeds. The study describes the features of validation and shows that continuous laboratory monitoring is important for detecting threshold transitions in agroecosystems, as well as in the oil production process. Understanding the level of xenobiotic content allows for proper application of technological adjustments to obtain food products that are safe for human consumption.
