Degradation of atrazine (ATZ) by ozonation in the presence of hydroxylamine (HA) was experimentally investigated in this study. The results showed approximately 80% of ATZ was degraded by ozonation in the presence of HA, while only 20% was degraded...

Evaluation of the side effects of poly(epsilon-caprolactone) nanocapsules containing atrazine toward maize plants.

Frontiers in chemistry

Oliveira HC, Stolf-Moreira R, Martinez CB, Sousa GF, Grillo R, de Jesus MB, Fraceto LF.
