ABSTRACT
Underwater welding is commonly used in joining pipelines and in underwater construction. Harmful and hazardous compounds are added to many flux cored wires for underwater welding and cutting, which can have a negative impact on marine life. This study is the first attempt to determine the influence of underwater welding on marine organisms using a standard model for assessing the changes in the early development of embryos of the sea urchin Scaphechinus mirabilis during short-term cultivation with the postulated toxicant.
Particles emitted during underwater welding pose toxicological threat to marine ecosystems. This fact requires the development of regulatory documents in the field of environmental protection and the introduction of compensatory measures to reduce the impact on marine organisms.
