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

Environmental contamination with pharmaceuticals is widespread, inducing risks to both human health and the environment. This paper explores potential societal solutions to human and veterinary pharmaceuticals in the aquatic environment. To this end, we adopt transition research’s multi-level perspective framework, which allows us to understand the dynamics underlying pharmaceutical emissions and to recognize social and technical factors triggering change. The authors' qualitative analysis is based on data collected through literature research and interviews with actors from pharmaceutical industry, the health

Endocrine-disrupting chemicals: economic, regulatory, and policy implications

July 2020

Endocrine-disrupting chemicals (EDCs) substantially cost society as a result of increases in disease and disability but—unlike other toxicant classes such as carcinogens—have yet to be codified into regulations as a hazard category.This Series paper examines economic, regulatory, and policy approaches to limit human EDC exposures and describes potential improvements. In the EU, general principles for EDCs call for minimisation of human exposure, identification as substances of very high concern, and ban on use in pesticides. In the USA, screening and

Life cycle based alternatives assessment (LCAA) for chemical substitution

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

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

Artificial Intelligence for chemical risk assessment

February 2020
copied to clipboard
As the basis for managing the risks of chemical exposure, the Chemical Risk Assessment (CRA) process can impact a substantial part of the economy, the health of hundreds of millions of people, and the condition of the environment. However, the number of properly assessed chemicals falls short of societal needs due to a lack of experts for evaluation, interference of third party interests, and the sheer volume of potentially relevant information on the chemicals from disparate sources.In order to explore

How to Get Beyond the Zero-Sum Game Mentality between State and Non-State Actors in International Environmental Governance

by
Columbia University
|
January 2020
copied to clipboard
This paper examines one specific theme of the democracy-environment interface of environmental governance: the participation of stakeholders in environmental policy formulation and implementation.After a short discussion of environmental governance, its main functions and challenges, the paper addresses the issue of stakeholder participation and the claim of a “democratic deficit” in international environmental governance. It stresses that while stakeholder involvement does not increase the democratic legitimacy, it may nevertheless increase the quality and through this the legitimacy of environmental policy processes

Rethinking chemistry for a circular economy

January 2020

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)
