Which of the following actions would NOT be appropriate for improving the reliability of PEC assessments?

Relying solely on one dataset would not be appropriate for improving the reliability of PEC assessments because it limits the breadth and depth of information considered in the evaluation. PEC assessments involve analyzing the potential environmental impacts of certain substances, and utilizing a single dataset may introduce bias or omit critical factors that could influence the results.

By consulting multiple sources of data, reviewing peer-reviewed research, and collaborating with environmental experts, you can gather diverse insights and corroborate findings, which enhances the overall reliability of the assessments. A well-rounded approach that incorporates various data points and expert opinions ensures a more comprehensive understanding of the environmental impacts, leading to better-informed decisions and conclusions in PEC evaluations.
