Consider the entire life cycle of nanomaterials and products containing them

By the Avicenn team – Last added June 2022

In order to not to repeat the mistakes of the pastIt is necessary that industrialists, risk assessment and management authorities and researchers consider the life cycle of nanomaterials in its entirety: from their design to their destruction or recycling, including their use/consumption.

A comprehensive approach – social life cycle assessment (SLCA) – is promoted by the United Nations Environment Programme (UNEP1). It can be applied to nanomaterials and must be conducted prospectively, prior to commercialization – not as a “firefighter” after health or environmental problems have arisen. This is a broader “benefit-risk” analysis than that commonly proposed by proponents of the traditional (and limited) risk approach. In particular, it considers the following questions: “what benefits/risks, for whom, where, when?

Taking into account the whole life cycle, by AVICENN

At present, scientists have very limited knowledge of the types of nanomaterials that are incorporated into products currently on the market, and a fortiori degradation residues of nanomaterials released throughout the “life cycle” of these products; they also know little about the mobility and transformations undergone by these products in the environment or in the human body: many parameters come into play, such as the degree of acidity or salinity of the water2On the influence of acidity on the physicochemical parameters of nanomaterials, see for example:
Fate of iron nanoparticles in the environment. Colloidal stability, chemical reactivity and impacts on plantsEdwige Demangeat’s thesis, Geosciences Rennes UMR 6118, 2018
Natural acids in soil could protect rice from toxic nanoparticles, Science News, April 2015

In May 2019, Science for Environment Policy reports on the advancement of a life cycle assessment method tailored to emerging technologies: The Lifecycle Screening of Emerging Technologies (LiSET). Will it be usable and used before the marketing of certain “nanos”? The question needs to be investigated.
