The effects of the atmospheric particulate material on aquatic organisms
Abstract: The industrial activity for iron (ore) producing and steel products processing results in the emission of particulate material in the atmosphere (APM) containing free metals and metallic nanoparticles. Many of these materials are emerging metals and nanoparticles that there are no environmental limits determined in the existing legislation. Dispersed in the atmosphere they may contaminate not only the aerial but also the aquatic environment and, passively, be incorporated by the local biota, including the humans. The accumulation of such metals and nanoparticles in the organisms may result in biochemical and physiological disfunctions impacting the homeostasis, metabolism and performance of animals and the health of the local population and the overall quality of life. It is noted that the Perna perna mussel is an excellent biomarker to analyze the metal content in particulate materials dumped into the sea by the mining industries. The present work aimed to perform a narrative review regarding the effects of the APM on the aquatic organisms, in special the mussel Perna perna. This specie can be considered a good bioindicator to analyze the AMP free metals and/or nanoparticles toxicity.
