From pesticides and PFAS to industrial pollution—news about the dangers of chemicals is everywhere. But how do we separate real risks from unnecessary fear? In this lecture, toxicologist prof. dr. Martin van den Berg provides a scientifically grounded perspective on the potential health effects of chemicals in our daily lives.
Thanks to advanced research and improved analytical methods, we know more than ever about the impact of synthetic substances on human health. But with knowledge comes responsibility: are we interpreting the data correctly? And how do health risks from chemicals compare to other lifestyle factors, like smoking? Van den Berg sheds light on the science behind health risk assessment and highlights how misunderstandings in the public debate can lead to unnecessary panic or misguided policies. Should we be worried, or are we developing an exaggerated fear—toxiphobia?

Some reactions from the audience
"I didn’t really know anything about toxicology before the presentation. Martin gave a clear explanation of what toxicology is and how research within toxicology is done."
"The professor's talk was broad and in-depth, very interesting. Clearly someone with a lot of experience."
"Very informative, with lots of information about research on chemicals in food, etc. I’m a bit less optimistic than the speaker on this topic—hopefully, he’s right!"
