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
