Phytoremediation of S-Triazine Herbicides: A Review

Hydroponic media are cleaned of prometryn using marsh pennywort (Hydrocotyle vulgaris L.) The ability of the aquatic plant Hydrocotyle vulgaris to remove prometryn from nutrient solution was examined. H. vulgaris was able to remove up to 94.0 percent of the original prometryn from the hydroponic culture medium in 30 days when experiment conditions were optimised. Prometryn's concentration dropped from 0.55 0.013 mg/L at the beginning of the trial to 0.036 0.001 mg/L at the conclusion. The removal kinetics (Ct = 0.4569e0.09t) were in accordance with the first-order kinetic equation. Prometryn's half-life (t1/2) was reduced from 27.16 days (without plant) to 5.58 days (with H. vulgaris). In H. vulgaris tissue, there was around 22% of the original prometryn residue, and after 30 days, the plant had broken down 11.7% of it.After 30 days, the prometryn metabolites 2,4-diamino-1,3,5-triazine and 2,4,6-trihydroxy-1,3,5-triazine were found in the hydroponic culture medium and plant tissue, respectively. According to the findings, H. vulgaris can be utilised to phytoextract prometryn, and it may also be able to successfully eliminate additional s-trazine pesticides from contaminated aquatic habitats.
