California's Almaden had a number of quicksilver mines. The mercury was used during gold extraction in the California Gold Rush, but the mines were closed in 1975 and have been converted into Almaden Quicksilver County Park. Despite the closure of the mines, there still remains a high mercury content in the nearby soil, creeks and rivers, and signs are posted alongside them warning people not to eat the fish.
我的问题是: 这地方土里还含汞, 长期住这儿, 会影响健康吗? 是不是种出来的菜和水果也不能吃呀? 谢谢先!
