Data collection, hazard characterisation and establishment of cumulative assessment groups in view of the cumulative risk assessment of pesticides for liver [PDF]

EFSA Supporting Publications
Abstract The aim of the present report is to collect data on toxic effects in the liver and gallbladder from various pesticides and their metabolites and, subsequently, to establish cumulative assessment groups (CAGs), in view of performing cumulative risk assessment (CRA) of pesticide residues for liver.

Going beyond One-to-One Mediation in Zone of Proximal Development (ZPD): Concurrent and Cumulative Group Dynamic Assessment

Eurasian Journal of Applied Linguistics, 2017
This paper reports on a study delving into the efficiency of two types of Group-Dynamic Assessment (G-DA, concurrent and cumulative) in teaching English articles. To this aim, two intact classes of third-grade high school students were included in the study and randomly assigned to Cumulative G-DA (n= 34) and Concurrent G-DA (n= 33) groups.

Risk Assessment of Chemical Mixtures in Foods: A Comprehensive Methodological and Regulatory Review [PDF]

Foods
Over the last 15 years, mixture risk assessment for food xenobiotics has evolved from conceptual discussions and simple screening tools, such as the Hazard Index (HI), towards operational, component-based and probabilistic frameworks embedded in major ...

Vulnerability as a Function of Individual and Group Resources in Cumulative Risk Assessment

Environmental Health Perspectives, 2007
The field of risk assessment has focused on protecting the health of individual people or populations of wildlife from single risks, mostly from chemical exposure. The U.S. Environmental Protection Agency recently began to address multiple risks to communities in the "Framework for Cumulative Risk Assessment" [EPA/630/P02/001F.

From Toxicogenomics Data to Cumulative Assessment Groups: A Mechanistic Framework for Chemical Grouping [PDF]

AbstractThe grouping of chemicals based on shared properties or molecular mechanisms of action is pivotal for advancing regulatory toxicology, reducing data gaps, and enabling cumulative risk assessments. This study introduces a novel framework usingChemical-Gene-Phenotype-Disease (CGPD) tetramers derived from the Comparative Toxicogenomics Database ...

Critical appraisal of the expert knowledge elicitation (EKE) methodology to identify uncertainties in building cumulative assessment groups for craniofacial alterations

Reproductive Toxicology
The European Food Safety Authority (EFSA) conducted a retrospective cumulative dietary risk assessment (CRA) on active substances (AS) and metabolites included in the plant protection products registered in Europe which could provoke craniofacial alterations.

The concentrations and cumulative risk assessment of phthalates in general population from Shanghai: The comparison between groups with different ages

Science of The Total Environment, 2018
Phthalates are predominantly used as plasticizers in daily consumer products. People are regularly exposed to phthalates through contact with these products. Phthalates are suspected to cause adverse effects in general population. We detected 10 metabolites of 6 phthalates in 3348 urine samples of general population (infants (0-1 yr), children and ...

Deliverable 2.1 - Report Describing Cumulative Assessment Groups For A Broad Range Of Chemicals, Based On Information Extracted From (Literature) Databases

, 2017
This report describes chemical substances relevant for the EuroMix Project; that is pesticide and non‐pesticide chemicals which can be grouped into cumulative assessment groups (CAGs) for consideration in cumulative risk assessment (CRA). The European Food Safety Authority (EFSA) has previously published an Opinion describing the approach to be ...

Scientific Opinion on Risk Assessment for a Selected Group of Pesticides from the Triazole Group to Test Possible Methodologies to Assess Cumulative Effects from Exposure through Food from these Pesticides on Human Health

EFSA Journal, 2009
Abstract Regulation EC No. 396/2005 from the European Parliament and the Council has required since September 2008 that cumulative and synergistic effects of pesticides be considered when Maximum Residue Levels (MRLs) are adopted. On 15 April 2008, the PPR Panel adopted an opinion on the suitability of existing methodologies and proposed a tiered ...
