Micromaterials and nanomaterials as potential emerging pollutants in the marine environment
Nanotechnology has been developed for different applications during the last twenty years. The areas where its application has been growing during the last decades, which has allowed their development, have been colloidal chemistry, electron microscopy, and microelectronics. Nanomaterials (NMs) are classified according to their chemical composition as inorganic materials, such as metal nanoparticles, quantum dots, and organic NMs, such as carbon-based materials and mixed organic-inorganic NMs. The main sources of NMs in the environment are naturally produced NMs, incidental sources, and engineered NMs. Because of the high use of nanotechnology, some anthropogenic NMs end up in the environment, where they are eventually transported to the ocean, becoming an emerging concern. In addition, due to their specific chemical characteristics, their analysis in the environment used to be complicated. This chapter compiles the main sources of NMs in the environment, revises the main analytical procedures for different types of NMs, and finally summarizes the occurrence of engineered NMs in water systems.
