Abstract: For evaluating the accumulation of phenol pollutants in benthic aquatic species, five representative populations of Bellamya were analyzed by 4-amido-antipyrin method. Muscle and entrails tissues were tested to identify the phenol content respectively. Precision and veracity of this measurement also be tested at the same time. In the result, 4-AAP method was proved to be an effect way to identify phenol content. Environmental phenol affects the content of it within the samples, and the differentiation exists in muscle and retrials tissues. Relationship of water-feeding time and phenol content of Bellamya was also examined.

Key words: 4-amino-antipyrin, phenol, Bellamya
