A: Medium-pressure lamp relative emission spectra. B: Degradation of aflatoxin. The results of three distinct studies are provided as mean percentage standard deviation. There is a significant difference in aflatoxin production at doses of 0, 1.22, 2.44, 3.66, and 4.88 [*P < 0.05, **P < 0.01, ***P < 0.001]. C: The Relationship between aflatoxin production and incubation time. As can be observed, the rate of aflatoxin in pure culture media is significantly higher than in rice, and the quantity of aflatoxin increases with increasing growth time [* **P < 0.001].

(a) D: Aflatoxin B1 level in Aspergillus flavus under the influence of UV irradiation time and distance to light source. (b) The amount of aflatoxin B1 of Aspergillus flavus decreases with increasing irradiation time, and this becomes more effective when it is placed at a distance of 20 cm from the light source [* **P < 0.001].
