Article Abstract
Air pollution is one of the most serious problems facing mankind because of its impact on ecosystems and human beings. Although particulate matter (PM) consists of both filterable PM (FPM) and condensable PM (CPM), most research has focused on eliminating only FPM. In this work, we introduce a filter system that removes both FPM and CPM from pollution source with high efficiency. The system consists of two reduced graphene oxide (rGO) filters and a condenser between them that can remove the usual FPM and at the same time CPM-induced FPM that typically leaves the pollution source unabated. The filters, quite effective in removing the PM with their three-dimensional structure, retain the removal capability even at high temperature and in acidic condition that prevail at the pollution source. The proposed rGO system could provide a complete solution for removal of both FPM and CPM from the pollution source.

Organochlorine pesticides (OCPs), including hexachlorobenzene (HCB) and pentachloronitrobenzene (PCNB), are highly toxic and persistent pollutants that pose significant ecological and human health risks. Their chemical stability makes them particularly resistant to biodegradation. In this study, we isolated and characterized Cupriavidus nantongensis HB4B5, a novel aerobic bacterium capable of efficiently degrading HCB and PCNB, without the accumulation of toxic intermediates.

Ciprofloxacin (CIP), a widely used fluoroquinolone antibiotic, has become a significant contaminant in aquatic environments due to its extensive use and incomplete metabolism. This review comprehensively analyses CIP pollution, including its sources, environmental and health impacts, and removal strategies. Chemical methods such as advanced oxidation processes and physical techniques like adsorption are evaluated for their efficiency in CIP removal.

Per- and polyfluoroalkyl substances (PFASs) are a large group of emerging organic pollutants that contaminate the environment, food, and consumer products. Textiles and other outdoor products are a major source of PFAS exposure due to their water-repellent impregnations. Determination of PFASs in textiles is increasingly important for enhancing their contribution to the circular economy.
