Popis: Abstract In a 28-days experiment, we investigated the dissipation of aflatoxin B1 (AFB1) (0.5–500 $${\upmu }\text {g}\,\text {kg}^{-1}$$ μ g kg - 1 ) by microbial (MD) and photodegradation (PD) in two contrasting soils (sandy loam and clay). Sterile incubation in darkness served as control (C). AFB1 was degraded in all scenarios according to simple first-order kinetics with 50% dissipation times of 20–32 (PD), 19–48 (MD), and 56–65 days (C), respectively. Dissipation rates were significantly lower ( $$\text {p}
