Introduction Nowadays, the most used pesticides are synthetic pyrethroids, as they are not only more cost-e ective but also less toxic to the vertebrate wildlife [1] compared to other pesticides (organochlorines, carbamates, and organophosphates). WebTriclosan and carbamazepine had distinctive toxic effects on unicellular living algae. Most strikingly, triclosan had more dramatic toxic effects on biochemical components than carbamazepine. Triclosan can affect algae primarily by inhibiting fatty acid synthesis and causing protein aggregation. northerneer building inspections
