Methods and tools for environmental technologies risk evaluation: the principal guidelines—a review

Abstract

The commonly used and developing engineering environmental technologies do not remain neutral for an ecosystem. The deepening climate changes are generally considered as the effects of human activities. There is thus no doubt that any human interference in the environment should be comprehensively checked at the beginning for all its positive and negative aspects for the environment as well as society health. There are two different analytical tools useful in environmental management: life cycle assessment (LCA) and risk assessment (RA). The first follows the product from “from birth to the grave” summing the environmental impact at all stages of its “life” including such elements like producing, used electricity, transport and many others. LCA refers to quantification and classification of all effects at all life stages and provides direct and indirect possible environmental interactions. On the other hand, risk assessment focuses on linking stressors and its possibilities and severity. RA tools reveal environmental and human health impacts of strictly separated elements, providing insight as to which emission consists of an important threat. This paper is focused on summarizing two the most used methods and tools for supporting the decision making process in use of environmental engineering technologies. In this paper, the fundamental differences between LCA and RA and benefits from their use has been contained.

The Nexus of ESG and Environmental Sustainability: Does Gender Diversity Make a Difference in Asian Companies?

“…Recently, interest has grown in understanding how companies can operate sustainably and contribute to developing a more sustainable economy and society. This interest is due to growing concerns about environmental and social issues and recognition of the potential for sustainable business practices to create long-term value for companies, their stakeholders, and all of society (Kowalska et al, 2021). The International Sustainability Standards Board (ISSB) has released a draft de nition of sustainability for a new reporting framework.…”

Tomato and Olive Bioactive Compounds: A Natural Shield against the Cellular Effects Induced by β-Hexachlorocyclohexane-Activated Signaling Pathways

“…In general, at environmental level, a remediation intervention consists in a series of measures aimed at removing or reducing the contamination sources, bringing the concentration of dangerous substances under the threshold levels. An environmental remediation project is mainly articulated in four steps: Preliminary investigation, for the evaluation of site contamination; Characterization, for the physicochemical characterization of pollutants; Risk assessment, for the determination of the Risk Threshold Concentrations (RTC); Remediation plan, for the implementation of site reclamation activities [ 8 ]. …”

“…Two kinds of analytical tools useful in environmental management, i.e., life cycle assessment (LCA) and risk assessment (RA), are discussed by the authors of [15]. LCA considers the product interaction with the environment at different product life stages.…”
