摘要

磁性纳米颗粒在水处理过程中去除污染物的有效性已得到充分证实，但将其引入水生生态系统引起了严重的毒性问题。本研究研究了铁氧体锌磁性纳米颗粒（ZnFe2O4−MNPs）对地中海贻贝（Mytilus galloprovincialis）的组织学和生理影响，并研究了同时暴露于这些纳米颗粒和杀虫剂硫虫嗪（TMX）的影响。

Assessing spinel zinc ferrite nanoparticles in aquatic ecosystems: Toxic threat or beneficial detoxifier for aquatic life?

The effectiveness of magnetic nanoparticles in removing pollutants during water treatment is well established, but their introduction into aquatic ecosystems raises significant toxicity concerns. This study investigates the histological and physiological effects of zinc ferrite magnetic nanoparticles (ZnFe₂O₄₋MNPs) on the Mediterranean mussel (Mytilus galloprovincialis) and examines the impact of concurrent exposure to these nanoparticles and the insecticide thiomethoxam (TMX).

Mussels were exposed to nominal concentrations of ZnFe₂O₄₋MNPs (1, 10, 100 mg/L) both individually and with TMX. Physiological assessments included measuring antioxidant enzyme levels (superoxide dismutase, catalase, glutathione S-transferase) and oxidative stress markers (malondialdehyde). Results showed that ZnFe₂O₄₋MNPs increased antioxidant activity but also caused dose-dependent pathological changes. In contrast, combined exposure with TMX significantly (p < 0.05) reduced antioxidant defenses, indicated by lower superoxide dismutase (SOD) levels and higher malondialdehyde (MDA) concentrations, suggesting oxidative stress and potential cellular damage.

These findings highlight the need for comprehensive toxicity assessments of nanoparticles in aquatic environments and advocate for their complete removal from water sources post-treatment. Further research is crucial to define the toxicity profiles of spinel ferrites to ensure their safe application in environmental remediation.

期刊介绍： Aquatic Toxicology publishes significant contributions that increase the understanding of the impact of harmful substances (including natural and synthetic chemicals) on aquatic organisms and ecosystems. Aquatic Toxicology considers both laboratory and field studies with a focus on marine/ freshwater environments. We strive to attract high quality original scientific papers, critical reviews and expert opinion papers in the following areas: Effects of harmful substances on molecular, cellular, sub-organismal, organismal, population, community, and ecosystem level; Toxic Mechanisms; Genetic disturbances, transgenerational effects, behavioral and adaptive responses; Impacts of harmful substances on structure, function of and services provided by aquatic ecosystems; Mixture toxicity assessment; Statistical approaches to predict exposure to and hazards of contaminants The journal also considers manuscripts in other areas, such as the development of innovative concepts, approaches, and methodologies, which promote the wider application of toxicological datasets to the protection of aquatic environments and inform ecological risk assessments and decision making by relevant authorities.
