Abstract： Water quality testing is an important means of ensuring the safety of drinking water. The concepts of detection limit and determination limit are two important concepts in water quality testing， which directly affect the accuracy and reliability of water quality testing results. Therefore， evaluating the rationality of detection limit and determination limit is of great significance for ensuring the quality of drinking water.

Keywords： water quality testing; determination limit; evaluation method; rationality judgment.

通过分析水质检测中检出限和测定下限计算公式以及实际应用可知，现代分析技术可以检出饮用水中可能存在的微量污染物，如有机物、重金属等，因此在水质检测中需要考虑检出限和测定下限的问题。（剩余4084字）
