“…The results show that after five cycles of the procedure, the 2,4-D removal efficiency has decreased to 96.1% from 98.4% [ 109 ]. In another study, two different photocatalysts which were TiO 2 /Al 2 O 3 /carbon nanotube nanocomposite and TiO 2 /Al 2 O 3 /graphene were utilized for photocatalytic degradation of metamifop where photodegradation percentage were 95% and above in the presence of UV light and 2 Lmin −1 of air [ 110 , 111 ]. Khan et al [ 112 ] found that TiO 2 can efficiently catalyzed the degradation and mineralization of herbicide derivatives chloridazon, and metribuzin in the presence of UV light.…”

The continually expanding global population has necessitated increased food supply production. Thus, agricultural intensification has been required to keep up with food supply demand, resulting in a sharp rise in pesticide use. The pesticide aids in the prevention of potential losses caused by pests, plant pathogens, and weeds, but excessive use over time has accumulated its occurrence in the environment and subsequently rendered it one of the emerging contaminants of concern. This review highlights the sources and classification of herbicides and their fate in the environment, with a special focus on the effects on human health and methods to remove herbicides. The human health impacts discussion was in relation to toxic effects, cell disruption, carcinogenic impacts, negative fertility effects, and neurological impacts. The removal treatments described herein include physicochemical, biological, and chemical treatment approaches, and advanced oxidation processes (AOPs). Also, alternative, green, and sustainable treatment options were discussed to shed insight into effective treatment technologies for herbicides. To conclude, this review serves as a stepping stone to a better environment with herbicides.

“…Hence, finding an effective treatment strategy for this type of herbicide is therefore an issue. The majority of techniques have been used, including photocatalytic degradation [5,6], phytoremediation [7], zeolite [8], chemical coagulants [9,10], and various types of absorbents [10,11]. Some of them work well, while others require to be paired with another treatment.…”

The growing demand for rice as a staple food by the expanding human population forces farmers to use substantial pesticide pest control on their crops. Water pollution is a serious problem as a result of overuse of agrochemical pesticides. Nominee-M, a recently created post-emergence formulation herbicide that has been investigated, contains the active component metamifop. Herbicides that protect crops from weed infestation frequently contain this chemical. The purpose of this study was to examine the effectiveness and potential of foxtail palm fruits as a potential source of activated carbon for the elimination of metamifop. Nitric acid (HNO3) was used in the chemical process of chemical activation to create the activated carbon from the foxtail palm fruits. The effect of adsorbent dose used (2 g, 3 g, 4 g and 5 g), contact time (60 mins, 90 mins, 120 mins and 150 mins) and initial metamifop concentration (10 mg/L, 12 mg/L, 14 mg/L, 16 mg/L and 18 mg/L) toward the efficiency of the prepared activated carbon in removing metamifop was studied in this research. The highest percentage removal was 86.65%, obtained at optimized value of 3 g of activated carbon used at 60 minutes of contact time and 10 ppm of initial concentration of metamifop. The study has proven that activated carbon produce from foxtail palm fruit potentially reduce metamifop in water resources that has been contaminated.
