“…High metabolic activity is correlated with an increase in ROS production, even for photosynthetic organisms. Several authors analyzed ROS levels in plants (see Sharma et al, 2017; Xie et al, 2009) and algae (see Alho et al, 2019; Almeida et al, 2019; Chin et al, 2019) to study the adverse effects of persistent pollutants such as metals and agrochemicals. Chloroplasts are cellular compartments that are highly susceptible to ROS due to their high production of O 2 and H 2 O 2 , electron flow, and the presence of metallic ions in these organelles (Davletova et al, 2005; Okamoto et al, 2001).…”

Carbofuran is one of the most toxic broad‐spectrum pesticides. We evaluated the effects of carbofuran on two species of microalgae, Pseudopediastrum boryanum, and Desmodesmus communis, through measurements of cell viability, biomass, the chlorophyll content, and the production of reactive oxygen species (ROS). The ability of these algae to remove carbofuran dissolved in the media was also determined. For the evaluations, both microalgae species were exposed to carbofuran (FURADAN 350 SC®) at concentrations of 100, 1,000, and 10,000 µg L‐1 for 7 days. Algae cell viability and chlorophyll‐a concentration were not affected by the presence of carbofuran. Both species grew when exposed to the pesticide; however, the microalgae D. communis grew less than its respective control when exposed to the highest concentration (10,000 µg L‐1 of carbofuran), indicating an adverse effect of the pesticide on this species. A significant increase in ROS production was observed in D. communis and P. boryanum when exposed to the highest concentration tested. The microalgae P. boryanum completely removed carbofuran in the media within 2 days, regardless of the concentration, whereas D. communis achieved the same result only after 5 days of exposure. Growth inhibition was observed only until the disappearance of carbofuran from the media. This study suggests the use of microalgae, mainly P. boryanum, as potential tools for the remediation of environments contaminated by carbofuran due to their resistance to the insecticide and their ability to remove it rapidly from water.

“…As far as we know there are no previous records for atrazine EC50 for the microalgal species tested in our study. However, there are results for other Chlorophyceae species such as Scenedesmus arcuatus (EC50 = 48.95 µg L −1 ), Scenedesmus quadricauda (EC50 = 86.37 µg L −1 ) (Chin et al, 2019), Clamydomonas reinhardtii (EC50 = 77.6 µg L −1 ) (Harshkova et al, 2021), and Selenastrum capricornutum (EC50 = 23 µg L −1 ) (Zhao et al, 2018). In these studies microalgae were exposed to atrazine over 72 or 96 h and the endpoint analyzed was growth inhibition.…”

Atrazine is a herbicide widely used in the control of weeds in crops such as corn, sugar cane, and sorghum. It is often found in aquatic environments, where it can potentially endanger nontarget organisms such as microalgae. The present study evaluated atrazine toxicity to seven different species of Chlorophyceae and the tolerance of the species to the herbicide was related to morphological, photosynthetic, chlorophyll‐a content and the activity of the glutathione‐S‐transferase enzyme (GST). The comparison of median effect concentration (EC50) values for growth inhibition indicates higher toxicity of atrazine for Pseudopediastrum boryanum and Desmodesmus communis, intermediate toxicity for Ankistrodesmus densus, Chlamydomonas puliminiorfes, and Raphidocelis subcapitata, and lower toxicity for Kirchneriella lunaris and Ankistrodesmus falcatus (EC50: 38, 42, 66, 103, 248, 1004, and 1585 µg L−1 atrazine, respectively). Principal component analysis (PCA) with algal characteristics suggested that the atrazine‐sensitive algae P. boryanum and D. communis were positively associated with photosynthetic levels and negatively associated with GST activity and chlorophyll‐a concentration. The PCA also suggested that the atrazine‐tolerant algae A. falcatus and K. lunaris were positively associated with morphological parameters, where the larger the cell size, the more tolerant. Although it is difficult to associate a single characteristic of algae as the key factor determining the tolerance to atrazine, results presented in this work indicate that the cell area, the photosynthetic parameters (mainly saturating irradiance), chlorophyll‐a content, and the biotransformation by GST in combination may be potential predictors for the differential tolerance of Chlorophyceae species to the herbicide.

Pesticide treatment dramatically reduces crop loss and enhances agricultural productivity, promoting global food security and economic growth. However, owing to high accrual and persistent tendency, pesticides could create significant ecological consequences when used often. Lately, the perspective has transitioned to implementing biological material, environmentally sustainable, and economical strategies via bioremediation approaches to eradicate pesticides contaminations. Microalgae were regarded as a prominent option for the detoxification of such hazardous contaminants. Sustainable application and remediation strategies of pesticides pollutants in the agriculture system by microalgae from the past studies, and recent advancements were integrated into this review. Bibliometric strategies to enhance the research advancements in pesticide bioremediation by microalgae between 2010 and 2020 were implemented through critical comparative analysis of documents from Scopus and PubMed databases. As a result, this study identified a growing annual research trend from 1994 to 2020 (nScopus > nPubMed). Global production of pesticide remediation by microalgae demonstrated significant contributions from India (23.8%) and China (16.7%). The author’s keyword clustering was visualized using bibliometric software (VOSviewer), which revealed the strongest network formed by “microalgae”, “bioremediation”, “biodegradation”, “cyanobacteria”, “wastewater”, and “pesticide” as significant to the research topic. Hence, this bibliometric review will facilitate the future roadmap for many scholars and authors who were drawing attention to the burgeoning research on bioremediation of pesticides to counteract environmental impacts while maintaining food sustainability.
