The material for our study was collected at the Far Eastern Federal University, Ajax Bay, Sea of Japan and studied at the St. Petersburg Polytechnic University of Peter the Great. The main indicators of the genesis of marine sediments are the complex granulometric composition of suspended particles. However, their study has not been widely used in marine oceanology research. The purpose of this work is to study, using the Analysette 22 NanoTec plus (Fritsch) laser particle analyzer, the granulometric composition of suspended particles formed during underwater welding and cutting using welding wire. The presence of microsized particles, which are extremely dangerous for human and animal health, is shown. According to the results of the study, it is shown that during underwater welding, particles with a diameter of less than 10 microns occur in fractions from 30 to 60%. This level of pollution can have a negative toxicological effect on representatives of aquatic organisms of marine ecosystems.
