Parizek等指出,硒可降低无机汞对大白鼠的毒性。然而Johnson指出,饲料中同时给予这两种元素似乎增加了这两者在器官内的蓄积。Ganther等以含有较高甲基汞及硒含量的金枪鱼及旗鱼,喂饲日本鹌鹑时,也发现有增加这两种毒物蓄积的倾向,却降低汞中毒所伴随的症候群。 Parizek, etc. pointed out that selenium can reduce inorganic mercury toxicity in rats. However, Johnson pointed out that the simultaneous administration of these two elements in the diet appears to increase the accumulation of both in the organ. Ganther et al. Also found that when Japanese quail was fed on tuna and swordfish containing higher levels of methylmercury and selenium, there was a tendency to increase the accumulation of these two poisons while reducing the symptoms associated with mercury poisoning.
