Methods are described for the determination of gallium and molybdenum in biological material using the technique of activation analysis. The limits of detection are 3 x 10/sup -10/ g for gallium and 10/sup -7/ for molybdenum. The method has been used to determine these elements in tomato seeds and in whole blood. Tomato seeds normally contain about 0.01 ppm of gallium and 1 to 3 ppm of molybdenum, but the latter element can be reduced by at least 95 per cent by growing the plants under conditions of molybodenum deficiency. One hundred ml of blood contains about 0.05 mu g of gallium and 1.4 mu g of molybdenum. (auth)
