The Leaching Calculator: A Tool for Predicting Leachability within the Framework of the New Mobility related Hazard Classes PMT and vPvM.
In this study, we propose a new metric for substance mobility in extension to the already implemented use of the log Koc as a sorption constant to the organic carbon content of soils. The new metric is based on the leachability of a compound in soil, ie the fraction thereof that is predicted to be transported to shallow groundwater. Apart from including climate and soil properties of European regions, the degradation half-life in soil is used in addition to the log Koc as an important parameter. This improves the applicability of the mobility concept for substances used under European environmental conditions due to the important role of degradation on a substance's potential to pass drinking water barriers such as soil or sediment. To factor in these additional parameters, the meta-model Leaching Calculator was developed. It is based on FOCUS PELMO as the underlying model to calculate the leachability of substances. FOCUS PELMO is a mechanistic leaching model that may provide a more comprehensive understanding of a chemical's movements in the environment. While calculations with FOCUS PELMO require many substance parameters and well defined pedo-climatic scenarios, the Leaching calculator only uses the log Koc and the half-life in soil as input parameters, and subsequently calculates the leachability based on a set of PELMO computations. Mobility assessments are then derived from proposed leachability thresholds.
期刊介绍:
Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas:
Science-informed regulation, policy, and decision making
Health and ecological risk and impact assessment
Restoration and management of damaged ecosystems
Sustaining ecosystems
Managing large-scale environmental change
Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society:
Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation
Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability
Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability
Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
