An international workshop, "The Measurement of Dissolved Organic Carbon in Natural Waters," will be convened in late spring of 1991 to critically compare currently available methods for the quantification of DOC in natural waters. Specifically, this workshop will address recent evidence that high-temperature catalytic oxidation (HTCO) techniques measure a major component of DOC in natural waters that is not quantified by conventional UV/persulfate (UV/PP methods. The main goals of the workshop will be to: (1) define consistent trends among DOC measurements by HTCO versus UV/P and other methods (based both on existing data and results for a small set of representative samples analyzed by workshop participants; (2) critically evaluate procedures for collecting, processing and preserving water samples for DOC analysis; (3) identify possible mechanisms for consistent differences in DOC measurements (as they relate both to handling and analytical methodology; and (4) recommend guidelines for future research on problems related to accurate DOC quantification as well as interim procedures for DOC measurements in ongoing field studies. Considerations will also be given to that analogous measurement of dissolved organic nitrogen.

一个名为“天然水中溶解有机碳的测量”的国际研讨会将于1991年春末召开，以批判性地比较目前可用于定量天然水中DOC的方法。具体地说，这次研讨会将讨论最近的证据，即高温催化氧化(HTCO)技术测量了天然水中DOC的主要成分，而传统的UV/过硫酸盐(UV/PP)方法没有对其进行量化。研讨会的主要目标将是：(1)确定HTCO与UV/P和其他方法测量DOC之间的一致趋势(基于现有数据和研讨会参与者分析的一小部分有代表性的样本的结果；(2)严格评估用于DOC分析的水样的收集、处理和保存程序；(3)确定DOC测量中一致差异的可能机制(因为它们涉及处理和分析方法)；以及(4)为未来有关DOC准确量化问题的研究建议指南，以及正在进行的实地研究中DOC测量的临时程序。还将考虑对溶解有机氮进行类似的测量。
