Problem formulation and hypothesis testing for environmental risk assessments of genetically modified crops.
Environmental risk assessments can provide high confidence of minimal risk by testing theories, "risk hypotheses", that predict the likelihood of unacceptable harmful events. The creation of risk hypotheses and a plan to test them is called problem formulation. Effective problem formulation seeks to maximize the possibility of detecting effects that indicate potential risk; if such effects are ...
متن کاملProspective formulation of environmental risk assessments: probabilistic screening for Cry1A(b) maize risk to aquatic insects.
A critical first step for environmental risk assessment is problem formulation to identify environmental entities of concern and determinants of exposure that place these entities at risk. A conservative screening level approach was used to evaluate the potential risk to sensitive aquatic species from maize-expressed Cry1A(b) protein occurring in a representative agroecosystem. Estimated enviro...
متن کاملIncorporating nonchemical stressors into cumulative risk assessments.
The role of nonchemical stressors in modulating the human health risk associated with chemical exposures is an area of increasing attention. On 9 March 2011, a workshop titled "Approaches for Incorporating Nonchemical Stressors into Cumulative Risk Assessment" took place during the 50th Anniversary Annual Society of Toxicology Meeting in Washington D.C. Objectives of the workshop included descr...
متن کاملOptimising environmental risk assessments
R egulated products such as genetically modified organisms (GMOs), plant protection products (PPPs) or feed additives for livestock are subject to an environmental risk assessment before they can be approved for use in agriculture. This assessment aims to evaluate any possible risk that the deployment of such products may pose to the environment. Robust environmental risk assessments require an...
متن کاملBuilding Better Environmental Risk Assessments
Risk assessment is a reasoned, structured approach to address uncertainty based on scientific and technical evidence. It forms the foundation for regulatory decision-making, which is bound by legislative and policy requirements, as well as the need for making timely decisions using available resources. In order to be most useful, environmental risk assessments (ERAs) for genetically modified (G...
