Presentation for HBM4EU Training School in Nijmegen (19-23 November 2018). The aim of this course is to help the trainees to understand the logical workflow and the mathematical framework that describe the integrated exposure modelling and how it relates to environmental, consumer, dietary exposure and get translated into biomonitoring data. A key component towards this direction is the internal dose modelling, materialized by the physiology based toxicokinetic (PBTK) models. The exposome concept is discussed and the state-of-the-art methods for external and internal exposure assessment are presented. They include the use of agent based modelling for population exposure assessment as well as the illustration of exposure biology workflow and EWAS to unravel associations between exposure and disease.

CYTOTHREAT
CytoThreat addresses the need to assess the risks of pharmaceuticals released in the environment, focusing on cytostatic drugs because they are highly hazardous compounds due to their genotoxic properties which may cause unexpected long term effects.
CROME
Introduction
The main environmental problem targeted by CROME-LIFE is the assessment of the impact on human health due to exposure to chemical agents originating either from environmental contamination (air, soil, water), or from consumer products (food contact materials, construction materials, cosmetics, clothes, etc.) through multiple routes, namely inhalation, ingestion and dermal contact in five distinct areas of southern Europe (Greece, Croatia, Slovenia, Italy and Spain).
COSMOS
This project addresses the safety assessment needs of the cosmetics industry, without the use of animals. The main aim of COSMOS is to develop freely available (open access and/or source) tools and workflows to predict the safety to humans following the use of cosmetic ingredients.
COPHES
COPHES is the Consortium to Perform Human Biomonitoring on a European Scale. Funded by the EU's Seventh Framework Programme, COPHES developed harmonised protocols allowing the collection of comparable HBM data throughout Europe. Its twin project, the feasibility study DEMOCOPHES, was launched one year later to test this hypothesis and to win information on levels and major determinants of exposure in Europe, as well as to establish protocols for the translation of HBM results into concrete policy recommendations.
CONTAMED
CONTAMED: Contaminant mixtures and human reproductive health – novel strategies for health impact and risk assessment of endocrine disrupters. CONTAMED aims to explore the hypothesis that combined exposure to endocrine disrupting chemicals in fetal life may lead to adverse delayed impacts on human reproductive health. To achieve this goal, CONTAMED will combine epidemiological approaches with laboratory science.
CITI-SENSE
CITI-SENSE works on development of sensor-based Citizens' Observatory Community for improving quality of life in cities. The project focuses on direct engagement of citizens within the fields of air quality, environmental quality of public spaces in cities and indoor air quality in schools. Funded by the EU's Seventh Framework Programme, 2010-2016, CITI-SENSE aims to empower citizens to contribute to and participate in environmental governance, to support and influence community and societal priorities and associated decision making.

What is HBM4EU?

HBM4EU stands for “Human Biomonitoring for Europe”. The main aim of the initiative is to coordinate and advance human biomonitoring in Europe.

Who does HBM4EU consist of?

HBM4EU is a joint effort of 28 countries, the European Environment Agency and the European Commission, co-funded under Horizon 2020. The HBM4EU initiative represents a novel collaboration between scientists and chemical risk assessors and risk managers, including several Commission services, European agencies and national representatives. The project will build bridges between the research and policy worlds and deliver benefits to society in terms of enhanced chemical safety.

What is human biomonitoring?

People are exposed to a complex mixture of chemicals in their daily lives through the environment, consumer products, food and drinking water and at work. Human biomonitoring allows the measurement of exposure to chemicals by measuring either the substances themselves, their metabolites or markers of subsequent health effects in body fluids or tissues. Human biomonitoring provides a useful tool for assessing cumulative exposure to complex mixtures of chemicals. By collecting data from a representative sample of individuals under continuous surveillance programmes, health practitioners are able to evaluate the exposure of the general population to chemicals over time. Information on human exposure can be linked to data on sources and health effects, in order to inform research on exposure-response relationships in humans.

How will HBM4EU initiative work with human biomonitoring?

HBM4EU will use Human Biomonitoring to assess human exposure to chemicals in Europe, to better understand the associated health impacts and to improve chemical risk assessment. Despite the existence of human biomonitoring programmes at national level and the large number of research and development projects ongoing both at national and European Union level, there is a clear lack of data on aggregate exposure to single substances and to combinations of chemical substances, as well as insufficient evidence-based knowledge on the link between external exposure via different routes, internal levels and human health. This knowledge is essential to inform effective policy-making to protect the European population from the impacts of chemical exposure on health. HBM4EU will form a bridge between science and policy. Our research will explore current questions in chemical risk assessment and management and will deliver answers that help policy makers to protect human health. Policy makers, stakeholders and scientists will together shape the strategic direction of HBM4EU activities. This transparent and collaborative approach will ensure that our research generates knowledge that addresses genuine societal concerns.

What are the main objectives of HBM4EU?

- Harmonise procedures and tools for human biomonitoring at European Union level;
- Provide and, where missing, generate internal exposure data and link this data to external exposure and the relevant exposure pathways;
- Develop novel methods to identify human internal exposure to environmental and occupational chemicals and establish the causal links with human health effects;
- Provide policy-makers and the general public with science-based knowledge on the health risks associated with chemicals exposure; and
- Improve chemical risk assessment in the European Union through the effective use of human biomonitoring data.
