Multimodal Action and Selective Toxicity of Zerovalent Iron Nanoparticles against Cyanobacteria

Popis výsledku v původním jazyce

Cyanobacteria pose a serious threat to water resources around the world. This is compounded by the fact that they are extremely resilient, having evolved numerous protective mechanisms to ensure their dominant position in their ecosystem. We show that treatment with nanoparticles of zero-valent iron (nZVI) is an effective and environmentally benign method for destroying and preventing the formation of cyanobacterial water blooms. The nanoparticles have multiple modes of action, including the removal ofbioavailable phosphorus, the destruction of cyanobacterial cells, and the immobilization of microcystins, preventing their release into the water column. Ecotoxicological experiments showed that nZVI is a highly selective agent, having an EC50 of 50 mg/Lagainst cyanobacteria; this is 20-100 times lower than its EC50 for algae, daphnids, water plants, and fishes. The primary product of nZVI treatment is non-toxic and highly aggregated Fe(OH)3, which promotes flocculation and gradual sett
