“…Cd can cause kidney failure and the chance of lung cancer after accumulating in the body in certain amounts [21]. Pb intake can damage the human somatic nervous system, leading to symptoms such as insomnia and headaches [22,23], while Zn may lead to reduced fertility [24]. The United States Environmental Protection Agency (USEPA) has listed heavy metals such as As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn as priority pollutants to be controlled [25,26], while the pollution of heavy metals in lakes has been receiving increasing attention from researchers and scholars since 2011 when the State Council of China promulgated the National 12th Five-Year Plan for Comprehensive Prevention and Control of Heavy Metal Pollution (2011-2015) [27].…”

Tibetan Plateau lakes have high ecological value and play a crucial role in maintaining ecological balance. This research aimed to study the pollution characteristics, ecological risk, and potential sources of eight heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn) in the surface sediments of 12 Tibetan Plateau lakes. The results of the toxicity risk index (TRI) showed that only Gongzhu Tso (28.09) and La’ ang Tso (20.25) had heavy metals that could pose a very high risk of toxicity to aquatic organisms. Hg posed the highest potential ecological risk to aquatic organisms. Based on the results of multiple analyses, we inferred that the contents of Cr, Cu, Hg, and Ni in sediments of Tibetan lakes were influenced by industrial and agricultural development; Cd, Pb, and Zn were influenced by transport and atmospheric transport; and As was derived from geothermal activity and rock weathering.
