Il peggiore lavoro del mondo? Annusare i bagni pubblici!
Se pensate che il vostro lavoro non sia un gran che, sappiate che poteva capitarvi di peggio, come fare l’analizzatore degli odori dei bagni pubblici in Africa e India. E per farlo serve anche un dottorato di ricerca.
E’ questo infatti l’ insolito lavoro che si è trovato a fare un gruppo di ricercatori. L’idea di base è abbastanza semplice: i bagni pubblici, specie nelle nazioni in via di sviluppo di frequente puzzano molto, molto spesso perché chi li costruisce, dovendo contenere i costi, si preoccupa degli aspetti tecnici ma non della questione dell’odore.
Per combattere il cattivo odore in modo efficace, però, bisogna sapere da cosa è composto, ed ecco dunque come i ricercatori si sono trovati a compiere una “analisi qualitativa e quantitativa dei costituenti volatili delle latrine”, una ricerca prima nel suo campo.
Le analisi, oltre la verifica qualitativa da parte di un ricercatore che doveva giudicare l’odore, hanno visto anche diversi test di laboratorio. Hanno scoperto che l’odore cambia a seconda che nella latrina siano favoriti i processi aerobici (che favoriscono un odore rancido o di concime) o anaerobici (che favoriscono odori di fogna). Lo zolfo avrebbe un ruolo fondamentale in molti dei cattivi odori presenti nei bagni pubblici.
