Analysis and differentiation of toxic and non-toxic cyanobacteria using Raman spectroscopy
Summary
This paper is not about microplastics. It used Raman spectroscopy to distinguish between toxic and non-toxic strains of cyanobacteria (blue-green algae) in water. While the detection technology overlaps with methods used for microplastic identification, this study focuses entirely on algal toxin monitoring with no connection to microplastic contamination.
Cyanobacteria, also known as blue-green algae, can produce cyanotoxins which can be harmful to animals and humans and can affect the ecosystem as well as the water quality. In marine or fresh water the cyanobacteria can grow to dense blooms with a high concentration of cells within a few days. Consequently, a fast and ideally real-time observation and analysis of cyanobacterial blooms is very important to ensure safety. We present a Raman spectroscopic approach to investigate and differentiate toxic and non-toxic cyanobacteria. For this, features of the acquired Raman spectra are highlighted to identify harmful cyanobacteria.

Understanding the Risks of Diffusion of Cyanobacteria Toxins in Rivers, Lakes, and Potable Water
This review covers the health risks of cyanobacteria (blue-green algae) toxins found in rivers, lakes, and drinking water, which can damage the liver and nervous system in humans. While not directly about microplastics, the research is relevant because microplastics in water can interact with cyanobacteria and their toxins, potentially serving as carriers that concentrate these harmful substances. The paper discusses various water treatment methods for removing cyanotoxins, many of which are also applicable to microplastic removal.

Microplastic characteristics differentially influence cyanobacterial harmful algal bloom microbial community membership, growth, and toxin production
Researchers investigated how different types of microplastics influence the growth and toxin production of harmful algal blooms in freshwater. They found that certain microplastic characteristics, such as shape and polymer type, significantly affected which microbial species thrived and how much toxin was produced. The study suggests that microplastic pollution may play an underappreciated role in worsening harmful algal blooms in lakes and reservoirs.
