巴西里约奥运会已经结束9个月了，但颁发的上百枚奥运奖牌却惨遭“退货”。巴西奥组委官员证实，至少有130枚奖牌有生锈或出现黑点等问题。目前，奖牌制造方巴西造币厂正在对问题奖牌进行修缮。

Olympic medals for more than 130 winners from the Rio de Janeiro Games last summer are rusting or chipping, according to officials.

巴西奥组委官员表示，130多名里约奥运会获胜者的奖牌出现生锈或落屑问题。

“We’re seeing problems with the covering on between 6 or 7% of the medals, and it seems to do with the difference in temperatures,” Rio Games communications officer Mario Andrada told reporters.

里约奥运会发言人马里奥-安德拉达告诉记者：“大约6%到7%的奖牌表面出现了问题，看起来与温差有关。”

He added that the decaying was “completely normal” after nine months, since only 1.34% of the medals are actually gold, and 30% of the sterling silver came from recycled silver.

他补充说，在9个月之后出现这种腐锈现象“完全正常”，因为仅有1.34%的奖牌是纯金的，而纯银奖牌中有30%是由再生银制成的。

"The most common issue is that they were dropped or mishandled, and the varnish has come off and they've rusted or gone black in the spot where they were damaged," Andrada said.

他说：“最常见的问题是奖牌被摔或保存不当，受损的地方就会出现表面脱落或生锈发黑的情况。”
