P. C.  aActivated carbon from pyrolysed sugarcane bagassebsilver nanoparticle modification and ecotoxicity assessment.h[electronic resource]  c2016  aActivated carbon from pyrolysed sugarcane bagasse (ACPB) presented pore size ranges from 1.0 to 3.5 nm, and surface area between 1200 and 1400 m2 g? 1 that is higher than commonly observed to commercial activated carbon. The ACPB material was successfully loaded with of silver nanoparticles with diameter around 35 nm (0.81 wt.%). X-ray photoelectron spectroscopy (XPS) analyses showed that the material surface contains metallic/Ag0 (93.60 wt.%) and ionic/Ag+ states (6.40 wt.%). The adsorption capacity of organic model molecules (i.e. methylene blue and phenol) was very efficient to ACPB and ACPB loaded with silver nanoparticles (ACPB-AgNP), indicating that the material modification with silver nanoparticles has not altered its adsorption capacity. ACPB-AgNP inhibited bacteria growth (Escherichia coli), it is a promising advantage for the use of these materials in wastewater treatment and water purification processes. However, ACPB-AgNP showed environmental risks, with toxic effect to the aquatic organism Hydra attenuata (i.e. LC50 value of 1.94 mg L? 1), and it suppressed root development of Lycopersicum esculentum plant (tomato). Finally, this work draw attention for the environmental implications of activated carbon materials modified with silver nanoparticles.  aNanoparticles  aNanosilver  aBagaço  aCana de açúcar  aCarvão  aMetal  aToxidez  aTratamento da água  aEconanotoxicology  aFunctionalization  aMetallic nanoparticles  aNanomateriais  aPorous carbon1 aSTRAUSS, M.1 aDELITE, F. de S.1 aCLEMENTE, Z.1 aCASTRO, V.
