ABSTRACT
The current study reveals the accumulation and As speciation in C. reinhardtii. Since microalgae are ubiquitous in wetlands and aquatic environments, As uptake and metabolism by microalgae will thus have fundamental impacts on As biogeochemistry. This paper aims to provide an overview of As uptake and speciation in microalgae, and to discuss the potential role of microalgae in mitigating the risk of As enrichment in paddy soils. Further studies on how microalgae affect As bioavailability and its volatilization are warranted.
