Machine learning for toxicity characterization of organic chemical emissions using USEtox database: Learning the structure of the input space

open access: yesEnvironment International, 2015
Toxicity characterization of chemical emissions in Life Cycle Assessment (LCA) is a complex task which usually proceeds via multimedia (fate, exposure and effect) models attached to models of dose-response relationships to assess the effects on target. Different models and approaches do exist, but all require a vast amount of data on the properties of ...

Impact of copper nanoparticles on porcine neutrophils: ultrasensitive characterization factor combining chemiluminescence information and USEtox assessment model [PDF]

open access: yesMaterials Today Communications, 2017
There is a need by the European Commission (EC) regulations, as well as others, to reduce the use of in vivo toxicity tests made on animals. Conventional in vitro tests were designed for non-nanoparticle sized entities, and therefore do not necessarily assess the adverse impacts of engineered nanoparticles (ENPs) on humans.

Modeling pesticides in global surface soils: Evaluating spatiotemporal patterns for USEtox-based steady-state concentrations

Science of The Total Environment, 2021
To better manage pesticide pollution in surface soils, we introduced a first-order-kinetics-based screening model to evaluate the steady-state concentrations of pesticides in surface soils while considering degradation, volatilization, plant uptake, and precipitation processes.

Development of USEtox characterisation factors for dishwasher detergents using data made available under REACH

Chemosphere, 2014
Because of the more and more stringent regulations and customer demand, dishwasher detergent manufacturers are constantly improving the composition of the products towards better environmental performances. In order to quantify the pros and cons of these changes on the lifecycle of detergents, as compared to conventional products, the use of Life Cycle

Improvement of calculations of the total Characterization factor in the USEtox model including a regional approach

Global NEST International Conference on Environmental Science & Technology, 2022
The USEtox model as one of LCIA models is an instrument to characterize the human toxicity impact. The model measures the intake of metals by population with meat products. The USEtox is the only model including geographical separation and wide database with organic and nonorganic chemicals. However, the USEtox does not provide any regional information,

A hazard classification system based on incorporation of REACH regulation thresholds in the USEtox method

Journal of Cleaner Production, 2019
Abstract REACH regulation classifies persistent, bioaccumulative, and toxic (PBT) substances based on regulatory thresholds established for selected physicochemical and toxicity properties. The underlying ideas behind this hazard classification system are: i) that is essentially dependent on the individual value of a restricted number of the ...

Ecotoxicity impact assessment of laundry products: a comparison of USEtox and critical dilution volume approaches

International Journal of Life Cycle Assessment, 2011
There is an increasing interest in the assessment and comparison of the environmental impacts of consumer products. Schemes such as Grenelle de l’Environnement, currently under development in France, aim to assess and communicate the life cycle impacts of consumer products.
