- Japanese quails (Coturnix japonica) were administrated with 4-NP in drinking water for 18 weeks.
- Administration of 4-NP in drinking water impaired the reproduction performance of Japanese quails.
- Administration of 4-NP in drinking water led to pathological lesion in the gonads of male quails.
4-nonylphenol (4-NP), a major degradation product of Nonylphenol ethoxylates (NPEOs), is widespread in environment. In this study, the effects of long-term 4-NP exposure in drinking water on Japanese quails (Coturnix japonica) were investigated. A total of 45 quails were evenly divided into 15 groups and administrated with various doses (0.1 μg Lâ1, 1.0 μg Lâ1, 10 μg Lâ1 and 100 μg Lâ1, which reflected the environmental concentrations of 4-NP) of 4-NP in drinking water. The results showed that 4-NP in drinking water had no effect on quails' food intake, but significantly decreased the quails' body weights (P < 0.05) in a time- and dose-dependent manner. The egg fertilization rates were also significantly decreased (P < 0.05) in all treatment groups. Moreover, the hatchability was significantly reduced (P < 0.05) in 10 μg Lâ1 and 100 μg Lâ1 groups, and the 14 d survival rates of young quails were significantly decreased (P < 0.05) in 1.0 μg Lâ1, 10 μg Lâ1 and 100 μg Lâ1 groups. Damaged spermatogenesis in male quails was observed in all treatment groups. Therefore, administration of 4-NP in drinking water impaired the reproductive ability of Japanese quails, and led to pathological lesions in the male gonads.
