Speciation of arsenic in milk from cows fed seaweed

BACKGROUND Including seaweed in cattle feed has gained increased interest, but it is important to take into account that the concentration of toxic metals, especially arsenic, is high in seaweed. This study investigated the arsenic species in milk from seaweed‐fed cows. RESULTS Total arsenic in milk...

Zusammenfassung:	BACKGROUND Including seaweed in cattle feed has gained increased interest, but it is important to take into account that the concentration of toxic metals, especially arsenic, is high in seaweed. This study investigated the arsenic species in milk from seaweed‐fed cows. RESULTS Total arsenic in milk of control diets (9.3 ± 1.0 μg As kg−1, n = 4, dry mass) was significantly higher than seaweed‐based diet (high‐seaweed diet: 7.8 ± 0.4 μg As kg−1, P
