鉱床周辺の水系調査

資源探査から環境修復まで

抄録

Traditional drainage survey has been used mainly for geochemical exploration and evaluation of anthropogenic metal contamination. To carry out the survey properly, some technical consideration should be paid besides just following related technical guidelines. Recently developed some. methods such as tracer-injection synoptic quantification of discharge, ng/l order Hg analysis, and high-resolution survey on first and second order streams enable the drainage survey to treat wider range of environmental issues.
