Silver nanoparticles (AgNP) are one of the most marketable nanomaterials worldwide. Their increasing production and their market insertion will deliver AgNP to the environment, exacerbating their human and environmental impacts. This review discusses the main techniques to synthesize AgNP, their properties, applications, and the cutting-edge knowledge on the effects of AgNP on human and environmental health. Through an identification of papers reporting AgNP until the beginning of 2016 in “ISI Web of Science,” and running different combinations of keywords or search strings, we identified six toxicological factors with a clear hazard potential to workers and consumers. A grading system is proposed to rank and evaluate toxicological properties of AgNP, which can be useful in supplying assistance on the classification of the priorities and concerns in the regulatory and standardization policies of the occupational health and safety issues on nanomaterials.
