AbstractThe world faces an increasing need to phase out harmful chemicals and design sustainable alternatives across various consumer products and industrial applications. Alternatives assessment is an emerging field focusing on identifying viable solutions to substitute harmful chemicals. However, current methods fail to consider trade-offs from human and ecosystem exposures, and from impacts associated with chemical supply chains and product life cycles. To close this gap, we propose a life cycle based alternatives assessment (LCAA) framework for consistently integrating quantitative exposure

Have you ever noticed how many chemicals shape people’s daily lives? They keep homes sparkling clean, boost food production, and are included in virtually all manufactured goods surrounding you right now. Chemicals drive the economy but as we produce more than ever before, they have to deliver their benefits without damaging our health and environment.Toxic lead paint for example is still used in many regions of the world and Highly hazardous pesticides continue to poison agricultural workers and contaminate the

Earth is running out of resources needed for manufacturing materials such as chemicals, minerals, and petroleum. Thus, these components are available only at increasing economic and environmental costs. As an important contribution to a sustainable future, chemistry and its products must be adapted to a circular economy (CE)—a system aimed at eliminating waste, circulating and recycling products, and saving resources and the environment.Nearly 140,000 industrial chemicals are marketed worldwide, and new chemicals are becoming more complex (e.g., stereochemistry, functional groups)

copied to clipboard
The Global Chemicals Outlook II – From Legacies to Innovative Solutions: Implementing the 2030 Agenda for Sustainable Development, mandated by the UN Environment Assembly in 2016, seeks to alert policymakers and other stakeholders to the critical role of the sound management of chemicals and waste in sustainable development. It takes stock of global trends as well as progress made and gaps in achieving the global goal to minimize the adverse impacts from chemicals and waste by 2020. The Global Chemicals

Microplastic contamination of the marine environment is widespread, but the extent to which the marine food web is contaminated is not yet known. The aims of this study were to go beyond visual identification techniques and develop and apply a simple seafood sample cleanup, extraction, and quantitative analysis method using pyrolysis gas chromatography mass spectrometry to improve the detection of plastic contamination.This method allows the identification and quantification of polystyrene, polyethylene, polyvinyl chloride, polypropylene, and poly (methyl methacrylate) in the

Chemicals of concern in plastic toys

We present a list of Chemicals of Concern (CoCs) in plastic toys. We started from available studies reporting chemical composition of toys to group plastic materials, as well as to gather mass fractions and function of chemicals in these materials. Chemical emissions from plastic toys and subsequent human exposures were then estimated using a series of models and a coupled near-field and far-field exposure assessment framework. Comparing human doses with reference doses shows high Hazard Quotients of up to 387

Reducing chemical pressure on human and environmental health is an integral part of the global sustainability agenda. Guidelines for deriving globally applicable, life cycle–based indicators are required to consistently quantify toxicity impacts from chemical emissions as well as from chemicals in consumer products. In response, we elaborate the methodological framework and present recommendations for advancing near-field/far-field exposure and toxicity characterization, and for implementing these recommendations into the scientific consensus model USEtox.The present work was supported by the “Global Best Practices

Coupled mass and heat transfer modeling in building envelopes to consistently assess human exposure and energy performance in indoor environments

April 2023
copied to clipboard

This study aims to predict human exposure to pollutants and heating load in buildings by developing a numerical model coupling heat and chemical transfers in the building envelope. The study characterizes the effect of temperature and air renewal rate on chemical emissions from building materials and human exposure. The results show that increasing indoor temperature by 10°C doubles the maximum indoor air concentration of volatile and semi-volatile organic compounds, leading to increased human exposure. The study also finds that higher air renewal rates lead to smaller intake fractions of pollutants from building materials. The study highlights the need to guide early design choices towards a good compromise between human indoor exposure and heating load, especially with the increasing emphasis on energy-efficient building design.

This is a pre-print manuscript pending publication in open access scientific journals.
