A child in Paris is at risk of lead poisoning after hundreds of children were checked following the Notre-Dame fire.
Health officials say the youngster needs monitoring following tests last week, but does not yet need treatment.
Checks are being done to find out whether the lead came from the fire at the famous 12th century landmark or another source.
The child’s school, near the cathedral, was closed in July after high lead levels were found on its grounds.
A total of 162 children have been tested in Paris after hundreds of tonnes of lead from Notre-Dame’s spire and roof melted during April’s fire.
Toxic particles were released into the air and settled on streets and buildings.
Authorities recommended blood tests for children under seven, as well as pregnant women who live nearby.
A deep clean was ordered at schools near Notre-Dame last month. Walls and furniture were to be wiped down and playgrounds hosed over during the summer holidays.
Despite the move, authorities’ response has been criticised, and in July a French environmental group sued Paris officials.
The spire and roof were devastated, but the cathedral was saved from total destruction.
An estimated 12 million people globally flock to Notre-Dame, making it one of the world’s most popular tourist attractions.
