Iodinated DBPs (I-DBPs), many more toxic than regulated chlorinated and/or brominated DBPs, are a major challenge in the supply of safe drinking water. While over 800 DBPs have been identified, the occurrence and precursors of toxic I-DBPs remain poorly understood. Herein, natural organic matter from two raw drinking waters was fractionated using ultrafiltration membranes into different groups based on molecular weight (MW).

Article Synopsis
- This study explored how microplastic polyester fibers, specifically polyethylene terephthalate (PET), can absorb various metal ions found in sewage.
- The research found that PET fibers could effectively retain metal ions like lead, cadmium, and mercury, with lead showing the highest absorption capacity.
- The findings suggest that when these microplastics are present in sewage treatment, they can contribute to the transfer of hazardous metals into the environment, particularly when sewage sludge is used on agricultural land.
Article Synopsis
- Aquatic nitrogenous compounds are categorized into dissolved organic nitrogen (DON) and dissolved inorganic nitrogen (DIN), with DIN including ammonia, nitrite, nitrate, and inorganic chloramines.
- The study highlights that nitrogenous disinfection byproducts (N-DBPs) formed from DIN can be more toxic than their carbonaceous counterparts, with ammonia, nitrite, and monochloramine significantly enhancing the formation of various harmful N-DBPs during disinfection processes.
- The findings suggest that the roles of DIN, particularly in real water treatment scenarios, warrant further investigation to improve water management strategies and minimize toxic byproduct formation.
The Indian Ocean is the third largest of the world's oceans, accounting for ~20 % of the global marine realm. It is geomorphologically complex, hosting a wide variety of ecosystems across basins, trenches, seamounts, ridges, and fracture zones. While modern exploration has contributed significantly to our knowledge of its coastal ecosystems, deeper waters (>1000 m) remain relatively unknown despite accounting for over 90 % of its total area.
