To efficiently degrade organic pollutants, photocatalysts must be effective under both ultraviolet (UV) radiation and sunlight. We synthesized a series of new metal-organic frameworks by using mild hydrothermal conditions. These frameworks incorporate three distinct bipyridyl ligands: pyrazine (pyr), 4,4'-bipyridine (bpy), and 1,2-bis(4-pyridyl)ethane (bpe).

Article Synopsis
- Researchers are focusing on the negative impacts of volatile organic compounds (VOCs) on both humans and aquatic life, influenced by growing public concern about water safety and aesthetics.
- A study in the Han River Basin, vital for drinking water in the Seoul area, found 17 VOCs, with 1,2-dichloropropane being the most common, particularly in polluted sites near sewage and industrial areas.
- Although VOC concentrations were generally low and posed a low ecological risk, the need for more ecotoxicity data and additional research on these compounds was highlighted.
Eight compounds from three categories of pharmaceuticals [5 antibiotics, 2 non-steroidal anti-inflammatory drugs, and 1 anti-epileptics] were monitored at 24 sites in the tributaries of the Han River watershed in South Korea, 2016. The seasonal occurrence, temporal-spatial variation, potential compound source(s), and a risk assessment of this watershed, which is the largest drinking water source in the country, were investigated. Clarithromycin was detected most frequently (72.

The tributaries of the watershed are vulnerable to contamination by effluents from nearby wastewater treatment plants (WWTPs) and non-point sources. In this study, a one-year monitoring study was performed to investigate the occurrence of 13 pharmaceuticals in 24 tributaries of the Han River watershed in October 2015.

The study also aimed to assess the severity of health and environmental hazards of household chemical products using the GHS.
Methods: 135 products were classified as 'cleaning agents and polishing agents' and 98 products were classified as 'bleaches, disinfectants, and germicides.
