Engineered nanomaterials represent a new and expanding class of chemicals whose environmental hazard is actually poorly determined. The peculiar behavior of nanomaterials makes them much more similar to new chemicals than to the corresponding bulk materials; this feature imposes reliable and standardized evaluation protocols for toxicity and ecotoxicity assessments. General rules for assessing nanotoxicity and the state of the art are periodically published in reports by control agencies. This review highlights the role of invertebrates as valuable and validated test organisms for assessing ecotoxicity of new and/or untested chemicals. The general scarcity of experimental data, their unequal distribution among the different nanomaterials and environmental conditions, the difficulties in manipulating nanomaterials and obtaining stable and homogeneous suspensions, the confusion arising from a not well defined metrics are discussed.
