Sulfadiazine dissipation in acidic tropical soils

Sulfadiazine (SDZ) residues have been detected in manured soils as well as their adjacent water resources, but its behavior is still poorly understood in acidic tropical soils. This research aimed to evaluate sorption, leaching, and biodegradation of 14 C-SDZ in four acidic soils from Brazil, using...

Zusammenfassung:	Sulfadiazine (SDZ) residues have been detected in manured soils as well as their adjacent water resources, but its behavior is still poorly understood in acidic tropical soils. This research aimed to evaluate sorption, leaching, and biodegradation of 14 C-SDZ in four acidic soils from Brazil, using OECD guidelines. Except for the sand soil ( K d = 2.6 L kg −1 ), SDZ sorption tended to be higher ( K d > 8.4 L kg −1 ) and more hysteretic (Δ H >> 1) in acidic soils. When freshly applied, SDZ leaching was low (
