Notre-Dame de Paris: Sasisho juu ya 'Hofu ya Ulevi wa Lead' na Urejesho

Kanisa kuu la Notre-Dame de Paris, ambalo ni maarufu sana, lilipata hasara kubwa kutokana na kuungua kwa moto tarehe 15 Aprili 2019. Mnara huo uliharibiwa na jengo hilo likadhoofika sana kutokana na miali ya moto iliyowaka kwa saa nyingi. Kiasi fulani cha risasi kilibadilika na kuwekwa katika maeneo yanayozunguka. Hii ilikuwa imesababisha tuhuma za ulevi.  

A recent study investigated the damu lead levels of adults in Paris. The findings published recently support the view that damu lead levels of adults living and working in the vicinity of the cathedral did not increase as a result of fire thus putting aside the fear of ulevi ⁽¹⁾.  

Imeorodheshwa kama tovuti ya Urithi wa Dunia wa UNESCO, Notre-Dame ilijengwa hapo awali mnamo 12^th karne na ilirekebishwa na kurejeshwa mnamo 18^th na 19^th century respectively. Its history is closely associated with history of Ufaransa and is symbol of Christian faith in Paris over long period of time ⁽²⁾ .  

Post-fire restoration of Notre-Dame entail issues relating to material sayansi, structural integrity, fire safety and preservation ethics ⁽³⁾ . Mnamo Julai 2020, mkurugenzi wa Maabara ya Utafiti wa Makumbusho ya Kihistoria (LRMH) alitaja 'tathmini ya uharibifu' kama kazi kuu. Msingi wa urejesho ulikuwa hali ya kanisa kuu baada ya moto ⁽⁴⁾ . A working group is is preparing a “digital twin” (an information system that brings together all technical and scientific data of Notre-Dame cathedral on a digital platform. The data from Scan 3D conducted earlier before the fire tragedy would come handy ⁽⁵⁾ . 

Kazi ya urejeshaji inaendelea kwa juhudi shirikishi za wataalam kutoka nyanja mbalimbali ⁽⁶⁾. Kufikia sasa, kiunzi kilichoteketezwa kinachozunguka kanisa kuu kimeondolewa. Grand Organ imevunjwa na kuondolewa. Awamu inayofuata ya ujenzi upya inaendelea. Kazi ya urejeshaji pamoja na kuunganisha na kurekebisha chombo inakadiriwa kukamilika ifikapo Aprili 2024. ⁽⁷⁾.
