Overview of PFAS Contamination and Regulatory Limits Per- and polyfluoroalkyl substances (PFAS) represent a class of over 4,700 synthetic chemicals characterized by strong carbon-fluorine bonds that make them highly persistent in the environment. These “forever chemicals” have been widely used in industrial applications and consumer products since the 1940s, including firefighting foams, non-stick cookware, water-repellent […]

Groundwater Contamination Concerns Groundwater serves as a primary drinking water source for billions worldwide, making its protection from anthropogenic contaminants a critical public health and environmental priority. The infiltration of pharmaceutical residues into groundwater systems represents a growing concern, as these biologically active compounds can persist and migrate through subsurface aquifers. Unlike industrial pollutants, pharmaceuticals

Overview of Cyanotoxin Contamination in Freshwater Systems Cyanotoxin contamination represents one of the most pressing environmental challenges in freshwater ecosystems worldwide. These potent toxins are produced by cyanobacteria (blue-green algae) during harmful algal blooms (HABs), which have become increasingly frequent due to nutrient enrichment, climate change, and other anthropogenic factors. The presence of cyanotoxins in

Artificial Sweeteners as Environmental Tracers Artificial sweeteners have emerged as powerful environmental tracers in recent years, providing unique insights into water contamination pathways and human activity patterns. Unlike traditional wastewater indicators, these compounds exhibit remarkable persistence in aquatic environments and resist conventional water treatment processes. Their widespread use in food, beverages, and pharmaceutical products, combined
