Abstract

The presence of pharmaceuticals and personal care products (PPCPs) in the environment has raised concerns due to their ecological effects. Chloramine-T, a common disinfectant, has not been well studied for its chronic toxicity in aquatic ecosystems. This study aimed to investigate the chronic toxicity and intergenerational effects of chloramine-T exposure on Moina macrocopa. The results showed that the 48-hour EC₅₀ of chloramine-T was 4.58 mg/L, indicating toxicity. After 21 days of exposure, the parental generation (F0) exhibited significant impairments in survival, development, and reproduction. However, subsequent generations (F1 and F2) showed gradual recovery when removed from the chloramine-T environment. F1 offspring from higher concentrations still displayed reduced survival and reproduction, whereas F2 and lower-concentration groups recovered completely. This study provides important insights into the chronic and intergenerational toxicity of chloramine-T and its ecological impacts.

氯胺- t在长时间暴露后的慢性和代际毒性。

环境中存在的药品和个人护理产品（PPCPs）由于其生态影响而引起了人们的关注。氯胺- t是一种常见的消毒剂，但其在水生生态系统中的慢性毒性尚未得到很好的研究。本研究旨在探讨氯胺- t暴露对大月牙蛾的慢性毒性和代际效应。结果表明，氯胺- t的48 h EC50为4.58 mg/L，具有毒性。暴露21天后，亲本代（F0）在生存、发育和繁殖方面表现出明显的损伤。然而，后代（F1和F2）在离开氯胺- t环境后逐渐恢复。高浓度组F1后代的存活率和繁殖率均下降，而低浓度组F2和低浓度组则完全恢复。这项研究为氯胺- t的慢性和代际毒性及其生态影响提供了重要的见解。
