Current Advances, Research Needs and Gaps in Mycotoxins Biomonitoring under the HBM4EU-Lessons Learned and Future Trends
ReviewThis article belongs to the Special Issue Human Biomonitoring and Risk Assessment of Mycotoxins.Mycotoxins are natural metabolites produced by fungi that contaminate food and feed
worldwide. They can pose a threat to human and animal health, mainly causing chronic effects, e.g.,
immunotoxic and carcinogenic. Due to climate change, an increase in European population exposure
to mycotoxins is expected to occur, raising public health concerns. This urges us to assess the current
human exposure to mycotoxins in Europe to allow monitoring exposure and prevent future health
impacts. The mycotoxins deoxynivalenol (DON) and fumonisin B1 (FB1) were considered as priority
substances to be studied within the European Human Biomonitoring Initiative (HBM4EU) to generate
knowledge on internal exposure and their potential health impacts. Several policy questions were
addressed concerning hazard characterization, exposure and risk assessment. The present article
presents the current advances attained under the HBM4EU, research needs and gaps. Overall, the
knowledge on the European population risk from exposure to DON was improved by using new
harmonised data and a newly derived reference value. In addition, mechanistic information on FB1
was, for the first time, organized into an adverse outcome pathway for a congenital anomaly. It is
expected that this knowledge will support policy making and contribute to driving new Human
Biomonitoring (HBM) studies on mycotoxin exposure in Europe.This study was co-funded by the HBM4EU, which has received funding from the European Union’s research and innovation programme Horizon 2020 under grant agreement No. 733032, and from the authors’ institutions.

efeitos tóxicos para o homem e para os animais. Reconhece-se,
atualmente, que as alterações climáticas terão impacto na distribuição
geográfica de algumas espécies de fungos produtores de micotoxinas o
que se traduzirá, previsivelmente, num aumento da exposição humana a
estes compostos. Pelas razões descritas, urge conhecer a atual exposição
a micotoxinas na Europa, com vista à sua futura monitorização e
à prevenção/redução do seu impacto na saúde. No âmbito da Iniciativa
Europeia em Biomonitorização Humana (HBM4EU) consideraram-se as
micotoxinas desoxinivalenol (DON) e fumonisina B1 (FB1) como substâncias
prioritárias, tendo sido abordadas várias questões relativas à avaliação
da exposição humana e o potencial risco para a saúde. No presente
artigo, apresentam-se as questões identificadas como mais importantes,
respostas obtidas e perspetivas futuras. Os resultados confirmaram
a exposição humana a DON, tendo sido obtidos, pela primeira vez,
dados harmonizados de exposição ao nÃvel europeu e derivado um valor
de referência para essa exposição. Foi ainda proposto, pela primeira vez
no HBM4EU, uma sucessão de eventos biológicos baseados no mecanismo
de ação da FB1 que permitiu associar a exposição durante a gravidez
ao desenvolvimento de defeitos do tubo neural no feto. Espera-se
que estes resultados possam contribuir para uma futura monitorização
da exposição a micotoxinas na Europa e para melhorar a avaliação de
risco destas substâncias.Mycotoxins are natural low-molecular-weight toxins produced by fungal
species that can be toxic for humans and animals. Under the climate
change scenario, some fungal species might shift their geographical distribution
in response to global warming, leading to changes in the pattern
of mycotoxin occurrence and, thus, increasing the risk of human mycotoxin exposure. For this reason, it urges to assess the current human
exposure to mycotoxins in Europe, to monitor internal exposure and prevent
future health impact. The European Human Biomonitoring Initiative
(HBM4EU), running from 2017 to 2022, was set to generate knowledge on
internal exposure and their potential health impacts. Within this initiative,
the mycotoxins deoxynivalenol (DON) and fumonisin B1 ( FB1) were considered
as priority substances to be studied and several policy questions
were addressed concerning their risk assessment. The present paper
presents policy questions identified within HBM4EU for these mycotoxins,
answers obtained and future perspectives. The exposure of the
general European population to DON was confirmed using new harmonized
data and a reference guidance value for human biomonitoring was
set for the first time. Additionaly, an adverse outcome pathway for neural
tube defects was proposed for FB1 for the first time. Hopefully these
findings may contribute to a more accurate risk assessment of European
population´s exposure to mycotoxins.O projeto HBM4EU recebeu financiamento do programa de investigação
