“…Our findings in this survey show that both the geographical distribution of Cd and the number of cacao-growing farms assessed in each of the four districts, might exert an influence on the variability of Cd in cocoa beans, a relationship that should be confirmed. This relationship must include other types of study, for example, microbiological evaluations, eco-physiological description, genetic analysis, and absence or presence of other plant species that reduce the concentration of Cd [59].…”

This study represents the first nationwide survey regarding the distribution of Cd content in cacao-growing soils in Colombia. The soil Cd distribution was analyzed using a cold/hotspots model. Moreover, both descriptive and predictive analytical tools were used to assess the key factors regulating the Cd concentration, considering Cd content and eight soil variables in the cacao systems. A critical discussion was performed in four main cacao-growing districts. Our results suggest that the performance of a model using all the variables will always be superior to the one using Zn alone. The analyzed variables featured an appropriate predictive performance, nonetheless, that performance has to be improved to develop a prediction method that might be used nationwide. Results from the fitted graphical models showed that the largest associations (as measured by the partial correlation coefficients) were those between Cd and Zn. Ca had the second-largest partial correlation with Cd and its predictive performance ranked second. Interestingly, it was found that there was a high variability in the factors correlated with Cd in cacao growing soils at a national level. Therefore, this study constitutes a baseline for the forthcoming studies in the country and should be reinforced with an analysis of cadmium content in cacao beans.

“…The presence of metals in vegetables is influenced by many factors, principally by the crop species and its metabolism, and by others such as the soil’s initial concentration of contaminants, pH, organic matter availability, and presence of other ions and molecules [ 16 , 17 ]. The kinetics of TMs’ uptake depends on the mechanisms of their ion toxicity, including the blocking of functional groups in biomolecules and the replacing of essential metal ions in biomolecules [ 18 ].…”

Graphical abstract In most of the samples, each individual metal content does not overpass the FAO/WHO threshold limits, nevertheless 25 % of the tomato samples were near or exceeded the Pb threshold value. The total metals content suggests that there is an important contamination in tomatoes and lettuces commercialized in the markets from Central and South zones of the DMQ. In addition, the organic products analyzed have an alarming metal content that should be considered.

“…Comparing both methods of analysis, it was observed that flame offers results in shorter times, allows working with larger sample volumes and interferences are lower. [14] Likewise, the analytical technique of inductively coupled plasma mass spectrometry (ICP-MS) together with the analytical technique of flame atomic absorption spectrophotometry (FAAS) were the later most repetitive methods. Inductively coupled plasma mass spectrometry (ICP-MS) is an analytical technique that is generally established for food analysis, it features high precision, shorter analysis time, low detection limits, and less interference.…”
