AN OVERVIEW OF NANOMATERIALS FROM MARINE ENVIRONMENTS

Abstract

Sea water is a harsh environment with high ionic concentration, which allows nanomaterial’s (NMs) to change their behaviour dramatically. Rapid agglomeration, destabilization, and deposition may cause the NMs to disappear from surrounding water. Organic substances contacts with metal-bearing NMs may alter their dispersion, physical and chemical properties, and durability in the water columns. To assess human and ecological hazards and develop regulatory standards for modified NMs release, accurate and sophisticated detection of engineered nanostructures in marine environments is essential. Still, due to the inadequacy of NMs characterization techniques, comprehending their destiny and behaviour in marine habitats are still limited. Sulfur species, organic compounds, trace element cycling, distribution, and interaction between colloidal and dissolved phases have all been found to be crucial candidates for analysing the different ecological processes courses in marine habitats using electrochemistry strategies coupled with advanced spectroscopy and microscopy techniques.
