ABSTRACT The contamination of aquatic ecosystems with heavy metals is a major risk to both human and environmental health. The origins, environmental behavior, and ecological implications of heavy metals are thoroughly examined in this review, with a focus on their toxicity, bioaccumulation, and persistence in water systems. Heavy metal levels are influenced by a variety of environmental parameters, including pH, redox potential, and organic matter.

Organelle-targeting ratiometric fluorescent probes: design principles, detection mechanisms, bio-applications, and challenges Manoj Kumar Goshisht, ab Neetu Tripathi, *c Goutam Kumar Patra d and Manohar Chaskar e Abstract Biological species, including reactive oxygen species (ROS), reactive sulfur species (RSS), reactive nitrogen species (RNS), F−, Pd2+, Cu2+, Hg2+, and others, are crucial for the healthy functioning of cells in living organisms.

Hydrazide based novel selective and sensitive optical chemosensor for the detection of Ni2+: Applications in living cell imaging, molecular logic gate and smart phone A novel flexible “N”, “O” rich hydrazide based Schiff base chemo-receptor 2-(benzamido)-N'-((pyridin-2-yl)methylene)benzohydrazide (L) has been designed, synthesised and characterised by 1H-NMR, IR spectroscopy, ESI-MS spectrometry and single crystal XRD analysis.
