“…The cathodic electroactivity has been promoted with the degradation of imidacloprid where voltage of 200 mV was generated for up to 9 days. In another study using a similar system, the highest removal of thiacloprid (32.5%) was achieved at low pesticide concentrate below 20 ppm with stable bioelectricity voltage of 202 mV [140]. The concentration of thiacloprid above 50 ppm induced oxidative stress to the microalgal cell and depressed the biomass growth.…”

Pesticides have been identified as major contaminants of various waterways. Being classified as potential endocrine disrupting compounds, pesticides in aqueous system are highly hazardous to aquatic organisms and the ecosystem. The treatment of pesticide-containing wastewater can be performed through several means, but a wastewater treatment strategy which emphasizes both treatment efficiency and sustainability is a necessity of current time. In this context, bioremediation has been increasingly promoted as an alternative technique for the remediation of diverse pollutants. Particularly, bioremediation which involves the utilization of microalgae for the removal or conversion of pesticides to the harmless or less harmful compounds is becoming a trend. Exploiting microalgae as a tool for wastewater treatment presents multiple advantages over conventional treatment technologies, which include an opportunity to simultaneously treat pesticide-containing wastewater and nutrient recovery for microalgae cultivation as well as less formation of toxic sludge. This review discusses the roles of microalgae in mitigating pesticide pollution issue, while offering an opportunity for nutrient recovery from various wastewater sources. Based on the current laboratory studies, the use of microalgae bioremediation as a promising strategy for pesticide treatment has been rationalized. The establishment of more pilot scale studies is highly encouraged to further facilitate the implementation of this treatment approach for practical application.

“…Various treatment approaches, such as adsorption [10], advanced oxidative processes [11], membrane ltration/separation [12], and biological treatment [13] can be found in the literature aimed at the remediation of pesticides from the aqueous medium. However, most remediation technologies have high cost, low e cacy, and the possibility of degradation products that may be equally or more toxic than the pesticide to be removed [14].…”

In the present approach, we investigated the performance of multifunctional nanomaterial MCM-41-Pirkle in the thiacloprid removal in water samples. In the batch adsorption tests, the effects of pH, contact time, initial concentration, and adsorbent dosage were evaluated using the factorial experimental design model and response surface method. The multifunctional MCM-41-Pirkle exhibited well-ordered hexagonal structure with space-group symmetry (P6mm), high thermal stability, good textural, structural, and morphological properties, as well as, large pore volume and high surface area. The factorial design was suitable to find the optimized conditions using a smaller number of experiments. Moreover, practically all the effects were significant, which indicates the correct choice of the relevant parameters for the thiacloprid remediation. The MCM-41-Pirkle exhibited a high and fast removal efficiency at a low concentration of thiacloprid, with up to 95.20% of thiacloprid removal in the initial 5 min. It is also possible to observe that the MCM-41-Pirkle has excellent thiacloprid removal potential at different pH values, since the removal efficiency was between 95.01–95.82%. In addition, the Pareto graph displayed the following decreasing order of significance for thiacloprid removal by the multifunctional nanomaterial MCM-41-Pirkle: nanoadsorbent mass > thiacloprid standard concentration > solution pH. Finally, a maximum removal efficiency of 95.83% was achieved at an equilibrium time of 5 min with pH 3 using 40 mg of nanoadsorbent at an initial thiacloprid concentration of 4.5 mg L− 1.
