“…HSF-CW grown with Phragmites australis was used to treat the herbicide 2,4-D and achieved removal efficiencies between 71% and 99%. They also reported that an increase in herbicide concentration reduced the removal efficiency but on the other hand, the influent dissolved organic carbon showed a significant effect on the removal of herbicide (González, Zúñiga-Benítez, & Peñuela, 2019). The enhancement of atrazine degradation was achieved in CW by implementation of bioaugmentation (increasing functional atrazine-degrading bacteria) and was reported that 5 mg/L of atrazine was reduced below the threshold value within 43 days of treatment time.…”

This article presents an update on the research and practical demonstration of wetland-based treatment technologies for protecting water resources and environment covering papers published in 2019. Wetland applications in wastewater treatment, stormwater management, and removal of nutrients, metals, and emerging pollutants including pathogens are highlighted. A summary of studies focusing on the effects of vegetation, wetland design and operation strategies, and process configurations and modeling, for efficient treatment of various municipal and industrial wastewaters, is included. In addition, hybrid and innovative processes with wetlands as a platform treatment technology are presented.

“…Among several pesticide compounds, 2,4-dichlorophenoxyacetic acid (2,4-D) is one of the world's most frequently used herbicides from the chlorinated phenoxy acids family due to its low cost, selectivity, effectiveness, and range of weed control [4,5]. However, it has been reported that 2,4-D is a neurotoxic herbicide, meaning that it can be absorbed through the skin or can be inhaled, which could cause damage to liver, kidneys, muscles, and brain tissue [6,7]. Besides, 2,4-D has been considered as a hormonal agent of toxicity II by the WHO and the US-EPA organizations [8].…”

This study compares the removal performances of sonocatalysis (SC) coupled with commercially available titanium dioxide (TiO 2 , P25) and combined sonophotocatalysis (SPC) with H 2 O 2 of 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide in aqueous media in batch experiments. A SC process (US/TiO 2 ) with 75 mg/L 2,4-D obtained 65.58 ±0.42% degradation, 7.84 ±1.3% mineralization, and 15.86 ±0.39% oxidation at a pH of 2, and a temperature of 35±1ºC under optimum conditions after 360 minutes, whereas 82.24±2.91% degradation, 44.50 ±0.11% mineralization, and 55.11±0.35% oxidation were obtained after 360 minutes with SPC (US/UVA/TiO 2 -H 2 O 2 ), with the addition of an optimum 250 mg/L of H 2 O 2 . The synergistic index was calculated as 1.77 that indicated the positive effect of the combined system on degradation efficiency when compared with the individual processes. Total costs were obtained as 5072 USD/kg for SC and 4135 USD/kg for SPC, showing the cost efficiency of the hybrid SPC process in comparison to the SC process. The obtained results confirmed that the hybrid SPC process was more effective than the SC process in degrading and mineralizing 2,4-D for removal. Operation time was shorter, energy consumption was lower, and operation cost was lower when compared to the SC process.

“…However, regardless of differences in α level, it was noticed that effect sizes remained consistent across different thresholds. González, Zúñiga-Benítez, and Peñuela (2019) assessed the efficiency of horizontal subsurface flow in the wetlands constructed for the removal of 2,4-D in aqueous solutions. Wetlands were constructed using fiberglass and grown with Phragmites australis.…”

This paper highlights a review of scientific papers published in the year 2019 regarding pesticides and herbicides. The scientific review presented in this paper includes the presence and occurrence of pesticides and herbicides in the environment. The entire review divided into different sections, which are grouped into four main sections. Each of these sections provides studies conducted on toxicology, ecological risk assessment, strategies of treatment, policies, modeling, and guidelines regarding pesticides and herbicides management.
