This report proposes environmental quality standards for dissolved oxygen (DO) for the protection of the different uses of water. The standards have been derived from Laboratory and field data cn the effects of deficiencies of dissolved oxygen in aquatic organisms taking into account its environmental chemistry. The standards proposed by other regulatorv and advisory agencies are included in the report fcr information and reference. The standards proposed are given in Table 1 and the justification for the standards is provided in Section 4. Whereas the standards suggested for the different freshwater uses are based on a relatively large database, inadequate data are available for the derivation of separate standards for the protection of estuarine life. The current standard analytical methods for dissolved oxygen are adequate in terms of sensitivity and limits of detection for monitoring compliance with the EQSs.
