چکیده انگلیسی
The B-series fumonisins (FBs) are some of the most prevalent mycotoxins produced as a secondary metabolite by Fusarium species growing on cereals. For decades they have been studied extensively in food and feed products, but there is no information about their occurrence in the aquatic environment or about how these mycotoxins are transported to the surface water and the groundwater. The aim of this study was to clarify the causes of fumonisin occurrence in aquatic ecosystems by examining the relation between mycotoxin contamination of crops and their levels in the aquatic environment. Water samples were collected from drainage ditches and wells or watercourses located in agricultural areas in the Wielkopolska region, Poland. Our research conducted on an annual basis showed the seasonal variability of fumonisin B1 concentration in the analyzed water samples, with the highest concentration in the post-harvest season (September to October) at 48.2 ng Lâ 1, and the lowest in winter and spring at 21.9 ng Lâ 1. Fumonisins B2 and B3 in water samples were not detected. Cereal samples were collected in the harvest season from each agricultural area close to tested water bodies. Mycotoxins were present in all cereal samples at concentrations from 43.3 to 1055.9 ng gâ 1. Our results confirm that fumonisins are transported to aquatic systems by rainwater through soil. On the basis of available literature, this is the first report concerning the presence of fumonisin B1 in different aquatic environments. To date their ecotoxicological effects are largely unknown and require further investigation.
