Dr Ovnair Sepai CChem FRSC

Ovnair Sepai is a Principal Toxicologist and leads the General Toxicology Group in Public Health England. 

The General Toxicology Group role is to advice the Department of Health and other Government Departments and Agencies on the human health aspects of chemical contamination in water, waste and land, chemicals in consumer products, cosmetics and toys. The group also support frontline Public Health professional during acute incidents and carry out risk assessment for both acute and chronic exposures.  This work has led to many publications, expert reports and guidance documents. 

Ovnair Sepai’s research interests are in the application of human biomonitoring and biomarkers in human health risk assessment. She leads the UK component of the large European human biomonitoring (HBM) programme. Through this initiative she has set-up a cross government group to take HBM forward in the UK: the initial aim is to have a nationally representative HBM study in England.

The use of human biomonitoring guidance values in risk assessment supports the principles of the 3Rs.
