Marine organisms are constantly exposed to complex chemical mixtures from natural and anthropogenic sources. One source that has raised concerns is the discharge water from ships equipped with exhaust gas cleaning systems, commonly known as scrubbers. During operation, ships with scrubbers discharge large volumes of scrubber water, known to adversely affect marine organisms, into the environment.

This study investigated the etiology, clinical features, and management of acute hydrogen sulfide (HS) poisoning in Zhoushan. A retrospective analysis was conducted on 10 patients admitted to our hospital between August and September 2023 due to two incidents of acute HS poisoning. The first incident involved fishermen working in a fishing cabin (6 patients), while the second involved sanitation workers during sewer maintenance (4 patients).

To reduce environmental impacts from the shipping industry, the FuelEU Maritime Regulation has set a binding 80 % reduction target for well-to-wake (WTW) greenhouse gas (GHG) emissions by 2050. This article presents a prospective life cycle assessment (LCA) comparing the environmental impacts of e-ammonia, e-methanol, e-Fischer Tropsch (FT) diesel, and e-liquefied natural gas (LNG)-for maritime applications in Europe. In addition to e-fuels, traditional propulsion technologies using very low sulfur fuel oil (VLSFO) and LNG are assessed, both with and without integrating ship-based carbon capture (SBCC) systems.

Catalan Institute for Water Research (ICRA), C. Emili Grahit 101, 17003, Girona, Spain; Universitat de Girona (UdG), Girona, Spain. Electronic address:
The increase in maritime traffic has led to substantial greywater discharges into the marine environment. Greywater, originating from sinks, showers, kitchen, and laundry facilities, contains a wide array of chemical contaminants influenced by on-board activities, ship size, and management practices. The lack of comprehensive regulations for greywater management, along with limited research on its chemical composition, highlights the need to characterize these waste streams.

It is the premature fusion of the sagittal suture, resulting in a "boat like" skull shape. Early surgical intervention is crucial to prevent complications, yet no standard procedure exists for patients over 12 months old.
