The Survivors head into the worst parts of the city to track down a mysterious kidnapper.
The air circulation and water quality 
aren't very good, after all.
.جودة الهواء والماء هنا ليست جيّدة قبل كلّ شيء
Weder Luft- noch Wasserzirkulation
sind hier nennenswert gut.
No circula mucho aire
ni hay agua limpia.
No circula mucho aire
ni hay buen saneamiento.
La ventilation et les canalisations
laissent à désirer.
Il ricircolo d'aria e la qualità dell'acqua 
non sono proprio il massimo.
A qualidade da circulação de ar
e água não são das melhores.
С вентиляцией и водопроводом
здесь тоже дела не ахти.
