在马拉喀什市（摩洛哥）城市污水扩散场的牛放牧的肌肉，骨骼，肝脏和肾脏中测定有毒和必需的微量金属。牛被发现受到有毒金属，特别是镉的严重污染，肝脏和肾脏中的含量较高，这是金属生物累积的特定靶器官。高镉含量似乎有助于锌和铜水平的降低。锌、铜和镉在肝脏和肾脏中的算术平均浓度分别为：肝脏126、112和5.1 μg/g，肾脏89、33和10.3 μg/g。
Toxic and essential trace metals were measured in muscle, bone, liver and kidney of bovine grazing on the municipal wastewater spreading field of Marrakech City (Morocco). Bovines were found to be seriously contaminated by toxic metals, especially cadmium, and levels were higher in liver and kidney, specific target organs for metal bioaccumulation. The high cadmium content seemed to contribute to a reduction in zinc and copper levels. The arithmetic mean concentrations of zinc, copper and cadmium in liver and kidney, were respectively: 126, 112 and 5.1 μg/g in liver; 89, 33 and 10.3 μg/g in kidney.
