Massive Project

Mechanisms of Arthropod Species Sensitivity In Variable Environments

Home

Background

Why?

Ecotoxicology, the science that investigates the impact of pollution on the environment is a practically oriented science and uses empirical approaches to develop guidelines and prescriptive limits for chemicals in the environment. Even though, these approaches are very useful and necessary to perform Environmental Risk Assessment, they are hardly based on the mechanistic understanding of factors determining the impacts on the environment. The MASSIVE project is asking the WHY-question in terms of sensitivity differences between species. Understanding the determining parameters of sensitivity differences between species on a process based level is the main purpose of MASSIVE. If we understand which species react sensitive to what kind of chemicals, this knowledge can be used in Environmental Risk Assessment and Biomonitoring.

What?

MASSIVE is an acronym for a "Mechanisms of Arthropod Species Sensitivity In Variable Environments". The MASSIVE project, which started in January 2006 is aiming at predicting the response of aquatic invertebrates to stress using the traits of taxa and the mode of action of the stressor as predictors. This will be investigated using univariate and multivariate statistical methods, modeling techniques and experimental approaches. The development of a tool that makes it possible to use a trait and mode of action based approach in Biomonitoring and Environmental Risk Assessment is ultimate goal of MASSIVE

Aim

In this project we aim to define and quantify traits, which have predictive potential for arthropod species sensitivity towards the model pesticide chlorpyrifos
in relation to the mechanistic processes of toxicity, i.e. the toxicokinetics and toxicodynamics by applying both theoretical, experimental and modeling approaches.

Who?

MASSIVE is a joint project of Alterra/WageningenUR, Environment Canada and Syngenta representing the triad of academia, government and business, which is a highly fruitful combination to develop pracitcal approaches for environmental science. Currently Paul J van den Brink (Alterra/Wageningen UR) as project leader and supervisor, Mascha N Rubach (Alterra/ Wageningen UR) as PhD student as well as Steve Maund (Syngenta) and Donald J Baird (Environment Canada/University of New Brunswick) as external supervisors are involved.

Where?

This project is based at Alterra/ Wageningen UR in The Netherlands, where most of the research is and will be carried out.
