Every week,more children arrive to work in the hundreds of primitive mines in the bush. Here they suffer long hours at dangerous jobs,getting gold from the dirt with mercury(水银) .
One of them is a 12-year-old boy named Saliou. Momodou is just 13 years old. This is a region of Africa where boys of Saliou’s age are expected to earn money for their families. He works in a bush mine on the Senegal-Mali border in the village of Tenkoto. According to the UN，mining is one of the worst forms of child labour. However,the laws are seldom enforced.
Children travel from mine to mine，moving with the gold. The AP reports that 6 months after Saliou arrived in Tenkoto,it was decided that the mine was nearly empty. So he and the boys walked for more than a week,crossed theSenegalborder and arrived at another mine inMali.
The World Health Organization says that mercury can affect the brain. It’s especially dangerous for children since their nervous systems are still developing. Typical symptoms of mercury include mental retardation,loss of balance,blindness and loss of hearing.
The buyers step in offering about $ 19 per gram. Once the deals are done，the gold is taken to the capital of Mali. There the price for gold is almost $ 23 a gram，nearly $ 4 more than the buyers pay the miners.
United Nations mining experts guess that 10% to 20 % of the thousands of mine workers in West Africa are children.
