Hasselt

His sister, Geertje van Hasselt, her school headteacher husband Simon, and their two daughters Hermi, 14 , and nine-year-old Sophia were murdered on arrival on 12 February 1943.

The man, identified only by the initials O.Y.T., has been living in Belgium since 2015 and was taken into custody on Wednesday after the Belgian police carried out a search in the eastern city of Hasselt, the prosecutor’s office said.

To determine this, scientists at the University of Aberdeen in the U.K., and Hasselt University in Belgium conducted two studies.

"We know that exposure to air pollution during pregnancy and infancy has been linked with still birth, preterm birth, low weight babies and disturbed brain development, with consequences persisting throughout life," Professor Tim Nawrot, a professor of environmental epidemiology at Hasselt University said in the same release.

In the first, 60 mothers who had just given birth at East-Limburg Hospital in Belgium voluntarily donated their placentas and blood samples, which were analyzed at Hasselt University.
