Abstract
The metals we are familiar with(Al, Ag, Au, Cu, Cd, Co, Fe, Ni, Pb, Zn, etc) are common elements and conservative pollutants. Although metals are often vital constituents of the metabolism of living organisms(trace elements}, a number of them are toxic if their concentration exceeds a certain threshold. It has long been recognized that measurements of trace metals in natural waters are often subject to large errors in terms of precision and accuracy. Since 1975 in US and European countries, seawater concentration of many trace metals have been shown to be factors of 10-1,000 lower than those previously accepted. Vertical profiles have been found to be consistent with known biological, physical and/or geochemical processes. These are resulted from major advances in analytical instrumentation and methodology for trace elements, and greater attention has been given to assuring the elimination of contamination during sampling, storage, and analysis.
Al, Ag, Au, Cu, Cd, Co, Fe, Ni, Ph, Zn 등과 밀접한 금속은 일반적인 원소이며, 지속적인 오염물질에 속한다. 금속은 생명체의 생리활동에 필수원소인 경우도 있으나 경우도 있으나 그 중의 일부는 정해진 한계값을 초과할 때에는 독성을 가진다. 자연수 중의 미량금속 측정은 정확도와 정밀도에 있어서 큰 오차를 가지고 있음이 장기간 인식되어 왔다. 미국과 유럽에서는 1975 년 이후 미량금속의 해수 중 농도가 과거에 인지된 농도보다
