Honey, renowned for its natural sweetness and versatility, serves as a flavorful and healthier alternative to traditional sweeteners in various culinary applications. This worldwide used sweetener, however, is extremely affected by anthropogenic activity through extensive agriculture, industrialization or traffic, and the impact of these influences can be detected by element and isotope analytical tools. Our former studies on unique, old series of EU (Hungarian) honeys proved their excellent relevance in reflecting the environmental conditions over a longer period of time based on their inorganic constituents but also showed not-contemporary carbon contribution which amount looks random, varying honey to honey. In present work the elemental composition and the contribution of the old carbon in aged honey samples from the eastern part of the USA were analyzed to verify the previous observations (in the EU) in a very different environment and continent. We used modern isotope ratio measurements (13C/12C, 14C/12C,) to determine the carbon isotopic composition and radiocarbon age of different US honey samples as well as the elemental concentration, Sr and Pb isotope ratio of the received honeys was determined by different inductively coupled plasma techniques (ICP-OES, ICP-MS, and MC-ICP-MS)
