Alves SR, Severino PC, Ibbotson DP, da Silva AZ, Lopes FR, Saenz LA, Bainy AC: Effects of furadan in the brown mussel Perna perna and in the mangrove oyster Crassostrea rhizophorae. Mar Environ Res. 2002 Sep-Dec;54(3-5):241-5.
Furadan is a carbamate pesticide used widely to combat agricultural pests. However little information is available about the toxicity of furadan in aquatic macroinvertebrates. The in vivo effects of furadan were evaluated in mussels, Perna perna, and oysters, Crassostrea rhizophorae. Glutathione S-transferase (GST), catalase (CAT) and cholinesterase (ChE) activities were measured in the gills of both species exposed to furadan (100 microg/l) for 96 h. No changes were observed in GST activity in the exposed groups. CAT activity was higher (9%) in the oysters exposed to furadan. ChE activity was inhibited by 64 and 35%, respectively, in C. rhizophorae and P. perna exposed to furadan, suggesting that the former is more susceptible to the toxic effects of furadan. |
