摘要

微塑料（MPs）是一种普遍存在的环境污染物，由于人类活动导致废水（WWs）未经适当处理或分散。我们的研究重点是验证一种创新的原型过滤器，以便其在污水处理厂（WWTPs）的未来应用，以减少MPs在环境中的释放。研究的目的是：西西里岛东部5个污水处理厂城市污水的入口和输出中-MPs浓度分别为10 μm和10 μm。-创新的MPs提取和原型验证定量测量方案。——绿贻贝（Mytilus galloprovincialis）血淋巴MPs的生态毒理学试验；溶酶体膜稳定性试验；频率分析；q-PCR: p53、DNA连接酶、Bax、BcL-2和Casp3基因)对未经过原型过滤器处理的污水处理厂输出水的影响。污水处理剂分别捕获了85%和73%的MPs >；10和MPs <；10 μm；相反，wwtps原型处理后的产出显示未捕获的MPs进一步减少了99%和92%。贻贝血淋巴分析显示，与正常的WWTPs输出相比，mp <；10和>；10 μm的过滤处理分别减少了100%和95%。我们发现，与原始的wwtp输出（18-24分钟）相比，暴露于原型过滤的WWs的贻贝的LMS时间（29-41分钟）更长。所有研究基因的MF和q-PCR显示，暴露于原型处理的WWs的贻贝遗传毒性降低。因此，该结果证明了原型效果，并将在下一步的研究中在实际的WWTPs中进行实地测试。

Innovative prototype for the mitigation of water pollution from microplastics to safeguard the environment and health

Microplastics (MPs) are ubiquitary environmental pollutants facilitated by anthropic activities as wastewaters (WWs) not properly treated or dispersed. Our study focused on the validation of an innovative prototype filter for its future applications in WWs Treatment Plants (WWTPs) to reduce the release of MPs in the environment.

The aims of the study were:

-
MPs concentrations >10 and <10 μm both in the inlets and outputs of urban WWs from five WWTPs of eastern Sicily.
-
innovative protocol for MPs extraction and quantitative measuring for prototype validation.
-
ecotoxicological test on Mytilus galloprovincialis (haemolymphs MPs analysis; Lysosomal Membrane Stability test - LMS; Micronucleus Frequency analysis - MF; and q-PCR: p53, DNA Ligase, Bax, BcL-2, and Casp3 genes) on output water by WWTPs treated or not by the prototype filter.

The WWTPs resulted in catching 85 % and 73 % of MPs >10 and MPs <10 μm, respectively; instead, the WWTPs-prototype treated outputs showed a further reduction of 99 % and 92 % of the uncaught MPs. The mussel haemolymphs analysis showed a decrease of 100 % and 95 %, respectively, for both MPs <10 and >10 μm in filtering treatment against the normal WWTPs outputs.

We revealed longer LMS times in mussels exposed to prototype-filtered WWs (29–41 min) compared to the raw output of WWTPs (18–24 min). MF and q-PCR of all studied genes revealed a reduced genotoxicity in mussels exposed to prototype-treated WWs. Hence, the results demonstrated the prototype efficacy, and it will be tested in real WWTPs at a field scale in the next study.

期刊介绍： The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere. The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
