Local authorities in Paris have ordered a "deep clean" at schools around the fire-damaged Notre-Dame cathedral, a city official said on Thursday, following a media report claiming the extent of contamination has been covered up.


Paris health official Arnaud Gauthier said that the cleaning had been ordered "to reassure us that the risk is minimal," adding that the levels of lead pollution caused by the April fire at Notre-Dame were not a cause for alarm.

There have been several scares over lead pollution since the blaze, with many locals fearing that the melting lead from the roof had ended up in the air they were breathing.

Environmental groups warned soon after the fire that 300 tonnes of lead in the roof of the Paris landmark had gone up in flames, posing a danger to residents in the area, particularly to children.

A report from the Mediapart investigative website on Thursday reported that dangerous levels of lead - as much as 10 times higher than the safe limit - had been detected in schools and creches surrounding the cathedral.

It added that Paris authorities had waited until May before conducting tests in the 10 creches and schools that are within 500 metres (yards) of the monument on the Ile de la Cite island in central Paris.

One result -- in the private Sainte-Catherine elementary school -- showed lead at a level of 698 micrograms per m2, 10 times higher than the limit of 70 microgrammes which is considered dangerous.

During a tour of the scorched edifice on Wednesday, reporters were told by Culture Minister Franck Riester that workers inside had to wear special masks because of the presence of lead which had seeped into some of the stone during the fire.

In June the French health authorities advised parents living in central Paris with young children and pregnant women to get their lead levels tested after an abnormally high level was detected in a child in the area.

The child was living in Ile de la Cité, where Notre-Dame cathedral is located, and the tests caused the regional health authority to trigger an "environmental investigation" to identify the cause or causes of the child's situation. 
"As a precaution", families with children under seven years old and pregnant women living on Ile de la Cité, were invited "to consult their doctor, who may prescribe a blood test for lead".
A screening consultation was also set up in the area.
In May, analysis carried out since the April 15 blaze detected lead dust in "very significant" levels on some streets and pavements outside the cathedral.
Between 10-20 grams of lead per kilogram (g/kg) were detected in soil samples, compared with normal background levels of just 0.3 g/kg, according to a statement from the police and the ARS regional health service.
The fire destroyed the roof and steeple of the 850-year-old landmark, melting the large sheets of lead that covered an intricate wooden framework. 
But officials at that time said testing had not revealed any lingering lead pollution in the air, with all atmospheric analyses showing less than the legal limit of 0.25 microgrammes per cubic meter.
