A Schematic Method for Sustainable Material Selection of Toxic Chemicals in Design and Manufacturing

Toxic chemicals used in product design and manufacturing are grave concerns due to their toxic impact on human health. Implementing sustainable material selection strategies on toxic chemicals can substantially improve the sustainability of products in both design and manufacturing processes. In this paper, a schematic method is presented for characterizing and benchmarking the human health impact of toxic chemicals, as a visual aid to facilitate decision-making in the material selection process for sustainable design and manufacturing. In this schematic method, the human health impact of a toxic chemical is characterized by two critical parameters: daily exposure risk R and environmental persistence T. The human health impact of a toxic chemical is represented by its position in the R−T two-dimensional plot, which enables the screening and benchmarking of toxic chemicals to be easily made through comparing their relative positions in the characterization plot. A case study is performed on six toxic chemicals commonly used as solvents for cleaning and degreasing in product development and manufacturing.

Toxic chemicals used in product design and manufacturing are grave concerns due to their significant impact on human health. Sustainable material selections are needed by industry to reduce the overall impact of toxic chemicals in both design and manufacturing. In this paper, we integrate the human health impact assessment into standard material selection process for developing a sustainable material selection metric for decision support in design and manufacturing. A schematic method is presented for characterizing and benchmarking the human health impact of toxic chemicals. A case study is performed on six toxic chemicals used as solvents in semiconductor manufacturing. Reliability of the schematic benchmarking results is checked and validated by comparing the results with that of conventional Human Toxicity Potential (HTP) method.

Human Health Impact

Abstract The research paper is aimed to modify the human health impact assessment of Cr in soils. The current article presents the input of several critical parameters for the human health Impact Score (IShum) assessment in soils. The modification of the IShum is derived using geological data (results of neutron activation analysis of soils are used in the IShum calculation; research area is divided using the watersheds) and population size and density. Watersheds reflect the local environmental conditions of the territory unlike the administrative units due to their geological independence. The calculations of the Characterization factor value underestimate the influence of the population size and density on the final result. Default regional values cannot be considered during the assessment of the potential human health impact for the big sparsely inhabited areas. In case of very low population density the result will be overrated and underestimated in the opposite case. The current approach demonstrates the generosity of the geographical separation in the USEtox model. The same approach can be utilized for other geo zones due to the accessibility of this information (area size, population size and density, geological and landscape features).

The Impact

There are many LCA methods and models (e.g. CML 1992, Eco-Indicator 95, IMPACT 2002+, TRACI, USEtox, etc.), used to characterize environmental impacts. Only four LCIA methods include spatial dimension at different geographical levels: Impact World+, LC-IMPACT, EDIP 2003 and USEtox (Bratec et al., 2019). Among these, three (Impact World+, EDIP 2003 and USEtox) include a human health impact category: human toxicity. The USEtox model, recommended by the European Commission, has already proved its efficiency for the coupling of environmental and geochemical studies. The Characterization factors of the USEtox describe environmental fate (FF) of the chemicals, their non- and carcinogenic effect (EF), direct and the indirect exposure (XF). All these factors vary depends on the applicable area. However, despite all advantages of the model, its geographical customization is rather generic. This paper presents the utilization of the already published case study (Belyanovskaya et al., 2019: 2020) with the indirect human exposure factor modification. The investigation present the modified biotransfer factor of the metals (Cr, Zn, Sb, As, Ba) of the meat product calculated specifically for different location inside the area &#8220;Central Asia&#8221;. The paper extends already published results with local data of the city of Vladivostok (Russia).AcknowledgementThe statistical data processing is supported by State program RF &#171;Science&#187;. Project FSWW-0022-2020.The impact assessment with the USEtox model is supported by the RSF grant (&#8470; 20-64-47021).
