Abstract

Purpose of Review

Nanotechnology has transformed various aspects of contemporary life, technology, and research. This is evident in the rising global demand for and use of nanoparticles, leading to a corresponding increase in their discharge into the environment through diverse human activities. In the last few years, the rampant use of copper oxide nanoparticles (CuO-NPs) has piqued interest.

Recent Findings

CuO-NPs are widespread and tend to remain in the environment, enabling them to increase in concentration through the food chain and ultimately impact human health. When aquatic organisms are exposed to CuO-NPs, it may cause oxidative stress. This can change proteins, cause lipid peroxidation, and damage DNA. This can ultimately cause cytotoxicity, genotoxicity, and epigenetic changes.

Summary

CuO-NPs produce reactive oxygen species (ROS), which can have various consequences for organisms and the environment. The objective of the review was to introduce a refreshed audit on the ecotoxicity, a comparison of systems related to CuO-NPs, and an assessment of the safe limit to prevent chronic toxicity across different taxa: aquatic invertebrates, plants, and algae. Additionally, the article briefly discusses the existing knowledge gaps in this area and makes recommendations for future research.

纳米氧化铜对水生无脊椎动物和光合生物的新威胁:综合已知与探索未知
综述目的 纳米技术改变了当代生活、技术和研究的各个方面。这一点从全球对纳米粒子的需求和使用不断增加就可见一斑,而通过各种人类活动排放到环境中的纳米粒子也相应增加。最近几年,纳米氧化铜微粒(CuO-NPs)的大量使用引起了人们的兴趣。当水生生物接触到 CuO-NPs 时,可能会导致氧化应激。这可能会改变蛋白质,导致脂质过氧化,并损伤 DNA。摘要CuO-NPs 会产生活性氧(ROS),对生物体和环境造成各种后果。本综述旨在介绍生态毒性的最新审计结果,比较与 CuO-NPs 相关的系统,并评估不同类群(水生无脊椎动物、植物和藻类)防止慢性毒性的安全限值。此外,文章还简要讨论了该领域现有的知识差距,并对未来研究提出了建议。
