Article Synopsis
- A study investigated the occurrence of sludge bulking in municipal wastewater treatment plants caused by filamentous bacteria overgrowth during low temperatures.
- Researchers used a lab-scale reactor to simulate bulking phenomena and analyzed the dynamics of filamentous bacteria, focusing on key factors affecting their growth and extinction.
- Results revealed that lower temperatures and sludge loading significantly influenced the competition between different types of filamentous bacteria, with low sludge loading stabilizing certain populations while higher loading led to their decline.
Long-term exposure to arsenic can lead to functional damage to many organs and can be life-threatening. It is of great significance to analyze the distribution characteristics of arsenic in water and evaluate its potential risk for preventing and controlling human health hazards caused by water-derived arsenic. Based on the published data from 2000 to 2022, the geographical distribution characteristics of arsenic in drinking water across China were systematically analyzed in detail, and the health risk of arsenic in drinking water was quantitatively assessed using disability-adjusted life years (DALYs), which represent the burden of disease.
