“…Currently, over 80% of ships are dismantled in the countries of South Asia, in conditions that threaten the environment and the safety of workers. In addition, the development of a common policy and legislation for the recycling of end-of-life vessels is a global and controversial issue [ 92 , 93 , 94 ].…”

“…According to data from 2016, 35%, 30%, 22%, 9%, 3.7% of the gross tonnage of recycled vessels (GTRV) were placed in facilities located in these five countries, respectively, and merely 0.3% of the GTRV underwent recycling in other countries of the world [ 15 , 75 , 95 ]. When dismantling the vessel, the following on-board hazardous substances constitute a particular hazard for the environment and human health: asbestos, polychlorinated biphenyls (PCBs), glass fiber, solid foam, and waste oils [ 93 ].…”

The article presents a comprehensive and cross-cutting review of key marine waste issues, taking into account: sources, fate, risks, transport pathways, threats, legislation, current challenges, and knowledge gaps. The growing amount of both human-created waste in seas and oceans and waste reaching marine ecosystems from land is one of today’s challenges for the global economy and the European Union. It is predicted that if no decisive steps are taken to limit the amount of this type of waste, there may be more plastic waste than fish in the oceans after 2050. The influence of microplastics and nanoplastics on living organisms remains undiagnosed. Within the international and EU law, solutions are being developed to properly manage waste on board ships and to reduce the impact of processes related to the recycling of the vessels on the environment. Currently, over 80% of ships are dismantled in the countries of South Asia, in conditions that threaten the environment and the safety of workers. After World War 2, large quantities of chemical weapons were deposited in the seas. Steel containers with dangerous substances residing in the sea for over 70 years have begun leaking, thus polluting water. For many years, radioactive waste had also been dumped into marine ecosystems, although since 1993 there has been a total ban on such disposal of radionuclides. The impact of the COVID-19 pandemic on marine waste generation has also been presented as a significant factor influencing marine waste generation and management.

Shipbreaking has great economic benefits but generates substantial hazardous materials as wastes to the surrounding environment of shipbreaking yards. Currently, a number of methods are exercised all over the world for breaking ships. However, 'beaching method' is of most concerns due to its nature of activities. A computer simulation has been carried out and the results reveal that the toxic wastes which, without proper management and treatment, accumulate on the yard ground and gradually diffuses into soil. Thus, leach to sea-water, contaminate and degrade water quality, create a declining trend of biotic structure and eventually affect the ecological systems resulting in sudden or gradual disappearance of mangroves and vegetation. Computer simulation results also confirm that if shipbreaking activities are performed on a bed that is constructed using pebbles of various sizes in such a way that the pebble size gradually increases and the bed permeability gradually decreases across the depth starting from the top surface of the bed, the concentration of hazardous materials could be restricted and catastrophic environmental damages could be avoided.The proposed shipbreaking approach is thought to be sustainable as it uses naturally found construction materials which could be reused for other purposes and offers cleaner, environmentally sound production process of raw materials without incurring significant implementation costs.

“…Safety aspects are crucial for polymers and plastics used in medical applications, food contact materials, children’s toys, and waste. Moreover, with the increase in the use of recycled materials, contamination can reach almost any domain [8,9]. Particular attention is focused on additives as they can easily diffuse throughout the polymer and are in direct contact with consumers [10,11].…”

Liquid extraction surface analysis mass spectrometry (LESA -MS) is a direct analysis method suitable for the analysis of polymers. It is based on a fast and efficient extraction of polymer components, such as non-intentionally added species (NIAS), post-polymerization residues, or additives, and residues resulting from specific uses followed by their MS detection. In comparison with batch methods, it is a “green” method, using negligible volumes of organic solvents, and it is cost-effective, avoiding lengthy sample preparation procedures. It can be used for the detection of known molecules (targeted analysis), identification of unknown species (exploratory analysis requiring MS/MS) and semi-quantative analysis, if standards are available. The to-date applications of LESA-MS in the field of polymer science are reviewed and critically discussed taking into account the hands-on experience from the authors’ laboratory. Future possibilities of LESA applications are highlighted.
