Article Synopsis
- Pesticides from rice farming can harm non-target organisms, impacting biodiversity, leading researchers to study their presence in river water and their effects on Boana faber tadpoles.
- The study found no major developmental issues in tadpoles but noted increased malondialdehyde (MDA) levels indicating oxidative stress after pesticide exposure, particularly with herbicide BTZ and fungicide TBZ.
- Histological examinations revealed significant changes in the tadpoles, such as inflammation and liver enzyme activity alterations, highlighting the negative impact of rice pesticides on local aquatic ecosystems and biodiversity.
Fungicides from rice cultivation (tebuconazole and azoxystrobin) alters biochemical and histological markers of hammertoad tadpoles (Boanafaber).

Tebuconazole (TBZ) and azoxystrobin (AZX) are fungicides frequently used in rice cultivation. Despite protecting crops against fungal diseases, these compounds can contaminate the natural environments close to the crops, exerting negative effects on non-target organisms, the present study aimed to characterize the contamination by fungicides of a river that flows in an area dominated by rice cultivation in the north of the state of Santa Catarina, SC, Brazil. Concentrations of TBZ and AZX found in the field were used to evaluate their negative effects on development, biochemical biomarkers and histopatology of the liver of a native tadpole species, the hammerfrog (Boana faber).
