HBM4EU-MOM: Prenatal methylmercury-exposure control in five countries through suitable dietary advice for pregnancy - Study design and characteristics of participants.

Background: Seafood is a major source of vital nutrients for optimal fetal growth, but at the same time is the main source of exposure to methylmercury (MeHg), an established neurodevelopmental toxicant. Pregnant women must be provided with dietary advice so as to include safely fish in their diet for nutrition and mercury control. The aim of this work is to present the design of a multicentre randomized control trial (RCT), which combines human biomonitoring (HBM) with dietary interventions using seafood consumption advice to pregnant women for MeHg control, and to collect information about other possible sources of exposure to mercury.

A simple method for direct mercury analysis in dried blood spots (DBS) samples for human biomonitoring studies.

Human exposure to mercury can have serious health effects, especially in vulnerable groups such as children and fetuses. The use of dried blood spot (DBS) samples to collect capillary blood greatly facilitates sample collection and fieldwork, being a less invasive alternative to blood collection by venipuncture, needing a small volume of sample, and does not require specialized medical staff. Moreover, DBS sampling reduces logistical and financial barriers related to transport and storage of blood samples.

A Tiered Approach for Assessing Individual and Combined Risk of Pyrethroids Using Human Biomonitoring Data.

Pyrethroids are a major insecticide class, suitable for biomonitoring in humans. Due to similarities in structure and metabolic pathways, urinary metabolites are common to various active substances. A tiered approach is proposed for risk assessment.

Methylmercury Risk Assessment Based on European Human Biomonitoring Data.

A risk assessment (RA) was conducted to estimate the risk associated with methylmercury (MeHg) exposure of vulnerable European populations, using Human Biomonitoring (HBM) data. This RA was performed integrating published data from European HBM surveys and earlier EFSA approaches (EFSA 2012). Children/adolescents (3 to 17 years old) and women of childbearing age (18 to 50 years old) were selected as relevant study population groups for this RA.
