“…Until 2023, both of them have published 15, 12, and 11 papers, respectively, on the topics of cadmium and lead in cacao. The last article on STE, entitled "Revealing the Pathways of Cadmium …" discusses the new findings about Cd uptake and translocation pathways in cocoa plants, which can help develop mitigation strategies to reduce Cd content in cocoa beans [14]. Meanwhile, the last article from FC, entitled "Incubating Tests Mimicking Fermentation …" explained that the fermentation experiment reduced the concentration of Cd in cocoa beans [15].…”

Theobroma cacao L., a special crop, is used to make famous culinary products like chocolate that are distributed all over the world. However, heavy metals like cadmium (Cd) and lead (Pb) can taint cacao, posing health risks to farmers and consumers. Scientists and researchers are examining ways to lessen the toxicity and uptake of Cd and Pb in cacao and are putting forth prospective strategies to restrict their uptake and accumulation in cocoa. This study aims to examine the literature from the last ten years of scientific research on preventing Cd and Pb absorption into cocoa using bibliometrics from RStudio. We collected 446 articles with 2118 authors from Scopus and Web of Science, published between 2014 and 2023. Food Research International and Science of The Total Environment are the two journals with the most relevant publications about Cd and Pb contamination in cacao. The findings of the bibliometric analysis revealed that not only Cd and Pb but also other heavy metals were present in cocoa. Several studies have explored ways to prevent or reduce metal uptake by cacao, such as biochar and organic matter, lime and micronutrients, and cacao genotypes with low accumulation. Postharvest handling, such as fermentation and winnowing, is also potentially used to reduce Cd and Pb content.

“…The rapid development of the world economy has led to the release of large amounts of anthropogenic cadmium (Cd) into the atmosphere. − The released Cd is ultimately deposited on the earth surface, which is absorbed by crops and accumulates in food chains. − Cadmium stable isotopes can be used to trace the geochemical cycles of Cd in the environment. ,− Natural and anthropogenic sources can be potentially tracked on the basis of the Cd isotopic composition and the large fractionation induced by evaporation and condensation due to industrial activities. − Several studies have successfully traced the source of soil Cd. , However, identification of the plant sources remains a challenge. Recent studies involving Cd isotopes in cereal crops mainly investigated the factors affecting Cd isotope fractionations via root uptake and Cd transport within the plant. ,,,,− In spite of using labeled Cd isotopes, studies have analyzed the role of different sources in plant tissues without evaluating the mass-dependent fractionations of natural isotopes induced by biological and abiotic processes. , Currently, the use of stable isotopes to trace Cd in plants based on mass-dependent fractionations is unknown …”

Rice roots and leaves were exposed to cadmium (Cd)-contaminated particles in a greenhouse to modify the fractionation during Cd uptake and transport in the plants by using the Bayesian mixing model. The exposure to atmospheric Cd in rice near a copper smelter was determined under the field conditions. The results showed that the leaves directly absorb and accumulate atmospheric Cd in other aboveground tissues by 84− 99%. Positive values of Δ 114/110 Cd Leaf−Particle (0.08−0.11‰), Δ 114/110 Cd Node−Leaf (0.77− 0.81‰), and Δ 114/110 Cd Grain−Leaf (0.39−0.43‰) following foliar exposure as well as Δ 114/110 Cd Root−Particle (0.19−0.22‰) and Δ 114/110 Cd Grain−Root (−0.29 to 0.34‰) following root exposure suggested that particles released heavy isotopes. The roots and leaves preferentially retained light isotopes and transported heavy isotopes upward. The Cd isotope fractionations in the plant were constant under both root and foliar exposures at two dosages. The results were used to correct the parameters in the isotope mixing models and to trace the source of atmospheric Cd in rice tissues in the field. Both models of isotope mixing and mass balance suggested 50−63% Cd deposition on the grains. This study provides a theoretical basis for tracing the source of Cd isotopes in plants.
