Based on 12 testing events, the average 48‐h LC50 for diazinon was μg/L, with a CV of %. One chronic test was conducted with diazinon; the 7‐d LC50 was μg/L. Control charts for the reference toxicant data are shown in Figure 2.

We also conducted acute toxicity tests with ammonia, chlor‐fenvinphos, and chlorpyrifos. Guidance Document on measurement of toxicity test precision using control sediments spiked with a reference toxicant, E.P.S.1/RM/30, 56pp.

ENVIRONMENT CANADA, 5. Quality assurance and quality control (QA/QC) are essential elements of laboratory toxicity test procedures.

A good QA/QC program provides a framework and criteria for assessing data quality, including a well-defined chain of responsibility, explicit data-quality indicators (DQIs), test procedures, protocols, and a mechanism for identifying and correcting potential problems.

The reference toxicants were NaCl for C. dubia and CuSO 4 for M. beryllina. These chemicals were chosen because they have a long history of use as reference toxicants and generally have lower coefficients of variation (CV) in comparison studies than do other toxicants.
