a a drinking-water intake rate of 2 L per day. Based on earlier data, water generally contributes 293 0.005–0.025 mg daily (i.e. 2–11% of the total daily oral intake of nickel) (MAFF, 1985). These 294 figures are similar to those presented in the European Union risk assessment for nickel (EU, 295 2008).
In addition, graphene coating is used as a protective layer against hydrogen embrittlement of copper without a prominent effect [ 34 ]. The quality of graphene layers, the coating methods, and the thickness of the coating could all affect the results [ 35].
