Several efforts are being taken to detect cyanotoxins using molecular and analytical techniques to understand their occurrence and distribution, however, these studies are discrete and localized. The detection of cyanotoxins within water bodies is a long-established challenge. In this article, conventional methods of detection and the recently used nanostructure based immuno-sensors are described. Several studies are considered where aptamers are utilised as the biorecognition probe and we have discussed their use in colorimetric, electrochemical and optical sensors for the detection of cyanotoxins. Furthermore, this article also reviews the current field deployable diagnostics for the real-time monitoring of cyanotoxins. Future work on fundamental studies, development of highly specific aptamers for recognising different congeners of cyanotoxins and the integration of sensors into portable or lab-on-a-chip devices could be interesting and useful research. Moreover, several studies related to the occurrence and distribution of cyanotoxins in the freshwater bodies of Asia are reviewed, with potential threats identified.

It begins with an overview of microplastic evaluation methodologies, followed by a discussion of recent advances in the abundance of microplastics in water, sediment, biota, wet and dry deposition, and particulate matter. Current quality assurance and control measures are also summarized. The majority of studies (44 %) examined sediment samples. In biota, the gastrointestinal system was the most evaluated for microplastics. Digestion (using H<sub>2</sub>O<sub>2</sub><span> and KOH) and density separation (using NaCl) are the most common microplastic extraction methods. We found that microplastic contamination is pervasive in all the surveyed protected areas, with varying levels of abundance geographically, and over 50 % of the biota ingest microplastics. The methodological discrepancies amongst the investigations, from sampling to microplastics characterization, make it difficult to compare the results and generate baseline data on microplastic contamination levels. Close monitoring and a standardized approach are thus required to determine the extent to which microplastics might enter and persist in protected area environments, as well as to devise effective mitigating strategies.</span></p></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46551016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
