Halogenation

Sporadic late-onset Alzheimer's disease (AD) is the most frequent cause of dementia associated with aging. Due to the progressive aging of the population, AD is becoming a healthcare burden of unprecedented proportions. Twenty years ago, it was reported that some indole molecules produced by the gut microbiota possess essential biological activities, including neuroprotection and antioxidant properties. Since then, research has cemented additional characteristics of these substances, including anti-inflammatory, immunoregulatory, and amyloid anti-aggregation features.
This study supports SDGs 3 and 6 by identifying passive chlorination at the point of collection as an effective and scalable strategy for reducing diarrhoea in children and improving access to safe and affordable drinking water in a low-income urban setting.
