Like all plants, roots of durum wheat absorb a very toxic metal naturally present in soils: cadmium (Cd, which contaminates the harvested grains. The European regulation EC 1323/2021 limits the Cd content of durum wheat to 0.18 mg Cd/kg grains, a threshold that has results from a downwards revision in august 2021. In France, about 5% of durum wheat plots produce harvests that do not comply with the current threshold, and up to more than 15% in some regions. The research group Ispa -Inrae and Arvalis-Institut du végétal have developed the "Bléssûr" tool amodel which makes it possible to predict the non-compliance of a future durum wheat harvest for Cd in order to allow growers to anticipate the necessary preventive measures. The tool requires (i) the soil analysis data that determines the availability of soil Cd and (ii) the variety that determines the plant ability to accumulate Cd in its grains. Bléssûr detects 82% of actual non-compliance cases and predictions of non-compliance are 75% reliable. For compliance cases, performance is 88% of detected cases with 89% reliability, respectively. Bléssûr has been extended to include lead (Pb), which is also regulated, and nickel (Ni) and Arsenic (As), which could be regulated. Bléssûr is freely available on the internet (https://ispa.bordeaux.inra.fr/services/blesur/). It aims at helping the sector to manage the hardening of regulations while improving the sanitary quality of durum wheat.
