Vitamin D stands for a group of fat-soluble vitamins, the so-called calciferols. These include the most important forms vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D plays an essential role in regulating the calcium level in the blood and in bone formation. It is also involved in other metabolic processes and in the protein biosynthesis.

Chloramphenicol (CAP) is a widely used broad spectrum antibiotic in food of animal origin. It is often used as a bacteriostatic antimicrobial agent in honey production.
Its lipophilic backbone interacts with nonpolar hydrocarbon residues of the analytes while the linked hydrophilic groups interact with polar functional groups to provide enhanced retention.

Due to their wide range of application as additives e.g. in fire-fighting foam, fiber and textile coating, food packaging, e. g. pizza cartons or paper cups, PFAS do not only end up in water bodies but also in sediments or also into the food chain. Therefore, monitoring is important.
