科学家发现树环通过亚马逊地区的汞含量暴露出非法采金活动。 Scientists discover tree rings reveal illegal gold mining through mercury levels in the Amazon.

科学家发现,亚马逊地区的树环通过显示高汞含量(采矿过程中释放的污染物),可以表明非法金矿开采。 Scientists have found that tree rings in the Amazon can indicate illegal gold mining by showing high levels of mercury, a pollutant released during mining. 来自康奈尔大学的研究人员从无花果树上采集样本,发现矿区附近的地区汞含量最高。 Researchers from Cornell University took samples from fig trees and found that those near mining areas had the highest mercury levels. 这一方法可以帮助当局监测和打击非法采矿,保护环境和附近社区。 This method could help authorities monitor and combat illegal mining, protecting both the environment and nearby communities.
