Abstract Based on the existing research, the morphological methods and biological models commonly used for determining the bioavailability of heavy metals in soils and crops were outlined, and several in vitro methods commonly used for studying the bioaccessibility of heavy metals in soils and crops were summarized, and the factors influencing the bioaccessibility and bioavailability of heavy metals were analyzed, with a focus on the effects of the physical and chemical properties of the media, the interaction between various forms of heavy metals and exogenously added substances on the bioaccessibility and bioavailability of heavy metals in soils, as well as the effects of heavy metal morphology and subcellular distribution of heavy metals on the bioaccessibility and bioavailability of heavy metals in crops. Future research directions on the bioaccessibility and bioavailability of heavy metals in soils and crops were suggested, which may provide theoretical references for future research.
