When the NP concentration exceeds 0.025 mg/L, the stability of DNA strands in shellfish will be affected and there will be a risk of carcinogenesis, mutagenesis and teratogenesis. Human health will also be affected due to seafood consumption. On the other hand, the DNA damage level and migration length show some difference among shellfish, oyster and clam exposed to the same nonylphenol concentration. This is because different shellfish species have different immunity to NP.

数据分析结果同时表明，在相同浓度的壬基酚处理组中，扇贝、牡蛎和文蛤血淋巴细胞的破坏率和迁移长度存在种间差异，这可能是由于这三种贝类对NP的免疫程度不同所致，但关于海洋生物对外界干扰因素存在不同免疫力的具体机制以及它们之间的差别，目前国内外的研究还不多见，具体研究还有待进一步的开展。
