Abstract

The innovational research in the field of nanotechnology is aimed to support and transform every sphere of human lifestyle. However, the environmental impact of engineered nanomaterials remains the topic of debate among researchers. Nano-components, more specifically nanoparticles, may have produced adverse effects on flora and fauna if accidently or deliberately released into the environment. Till date, there are no specific regulatory policies for the safe use of nanomaterials as they are considered under the broad categories of hazardous chemicals and reactive wastes. The regulations of nanomaterials cannot be similar to the bulk materials due to the huge gap in their properties. The rules should be based upon the scientific understanding of the nanomaterials. With the ongoing globalization of nanomaterials, international coordination, and harmonization, there is an urgent need for making the sound regulatory approaches for the safer use of nanomaterials. This chapter reviews and outlines the risk associated with nanomaterials, current regulatory approaches, and efforts in developing the sustainable nanotechnology.

Short Question Answers

  • Answer 1. Risk governance here refers to the application of the governing approach to tackle the issues of risks associated with the excessive release of nanomaterials in the environment. In particular, the governance works in portions, that is, firstly, the risk governance recognizes that decisions about issues of risks are not perspectives of the group of people rather those are scientifically evident facts. After the validation and assessment of risks, the preventive or safety frameworks are designed. The designing of the framework mainly involved the scientific, aesthetic, and administrative factors. In addition, all the financial feasibility aspects need to be taken care for the proper management of environmental impact of hazardous materials.

  • Answer 2. “Sustainable development” refers to the production and consumption of goods and resources in a manner that the needs of the current generations can be satisfied without compromising, limiting, or threatening the needs and environmental conditions of future generations. For nanotechnology, a wealth of applications has been proposed. For instance, nanotechnology enables the manufacturing process with lesser energy consumption and waste generations, thus saving the expenditure on carbon trading. Nanotechnology is not restricted to the production of nanoparticles but can also be a decisive step of complex productions. Such ways lead to the macro productions of products. For instance, the potential application of nano-based catalysts in the sector of energy production. On a bigger approach, certain converging technologies involve various macro-production and result in “meta-technologies” such as computing and biochemical analytics. The interdependence of these technologies with each other has shown that attributing sustainability to any technology is very tricky due to the intertwined network of production protocols.

  • Answer 3. Many scientific methods have been developed to estimate the sustainability of the nanomaterials. These methods mainly focus on the understanding of environmental and the societal and economic dimensions of chosen particles. The common risk assessment methods for safer use of nanomaterials have been discussed below:

    1. (a)

      Life cycle assessment

    2. (b)

      Future technology analyses

    3. (c)

      Nanotechnology assessment

  • Answer 4. The concept of risk treatment for the sustainable development of nanotechnology majorly depends upon four factors such as:

    1. (a)

      Involvement of social, economic, and biophysical factors

    2. (b)

      Guidance on how to use and deal

    3. (c)

      Consider future cycle for the remediation

    4. (d)

      Participation and contribution to the assurance

  • Answer 5. The international organization for standardization includes safety data sheets (SDS) for the synthesis of nanoparticles, utilization, and their practical analysis. Following are the key points that are included for the formatting of SDS:

    • The marking of SDS data should be very fast, due to enlargement in data availability.

    • Transparent and strong information should be provided for the nanoparticles when CAS number of bulk materials is used.

    • Statement and assertion should be provided when toxicological evidence is not accessible.

    • Declaration of statement provided for the exposure limits and application of bulk and nanomaterials.
