The following work is an advance that proposes to identify and integrate the national studies related to the determination of cadmium in cocoa soils of Barlovento, Edo. Miranda, Venezuela, as well as collecting the evidence that indicates Tuy river´s water as a tributary of this metal. Eight cocoa sectors of Barlovento have been chosen for the measurement of edaphic cadmium. The risk assessment code values, all above 4%, suggest the possibility that a significant portion of the cadmium associated with cocoa substrates is transferred to cocoa beans; this, added to the content of soil total cadmium always higher than the global mean concentration of this metal, suggests that the substrates of this region appear to be contaminated, however, it results necessary to construct local reference values to discriminate between anthropic and lithological influence. The concentration of total cadmium in suspended particles of the Tuy basin from Araguita to its mouth is significantly higher than that found in the evaluated cocoa substrates of Barlovento, and similar trend is exhibited by the bottom substrate of the same river, which shows the potential of Tuy river´s water and substrate as tributaries of this pollutant.
