A study investigated the toxicological effects of combustion particles from marine fuels with different sulfur contents. Ship emissions, such as sulfur oxides and particulate matter, have been reduced due to restrictions on fuel sulfur content. The study found that while different fuels resulted in a reduction in cytotoxicity, other toxicological outcomes, such as genotoxic and mutagenic potentials, were more strongly correlated with the polycyclic aromatic hydrocarbon contents in the particulate matter. The researchers concluded that in addition to reducing fuel sulfur content, additional particle abatement systems should be considered to minimize the adverse effects of shipping emissions on human health.

The article offers information on China's extension of its emission control areas to its entire coast from January 2019, which reveals the pressure facing the global shipping fleet, bunkering industry and fuel-testing agencies as they face imminent low-sulphur regulations. Topics include incidences that put pressure on the industry to guarantee the provision of sufficient high-quality, low-sulphur fuel for the global fleet; and sulphur fuel oil-powered vessels will be banned on inland waters.

The article discusses the concerns of the shipping industry regarding new environmental laws that cut the global limit on the sulfur content of marine fuel from 3.5% to 0.5% from January 1, 2020 in order to reduce emissions from sulfur, which cause air pollution and acid rain. Buying low-sulfur fuels could cost 60 billion U.S. dollars, according to Suresh Sivanandam of Wood Mackenzie. Shipowners will also need to invest in scrubbers or use greener alternatives such as liquefied natural gas.

The article reports that according to C.K. Yoo, chief executive officer (CEO) of Hyundai Merchant Marine (HMM), low-sulfur fuel regulation taking effect in 2020 to bring transformative change driven by new maritime technologies similarly as introduction of mega-ships. Topics include need of collective response for addressing the challenge of meeting new emissions reduction regulation, concerns over the commercial and operational challenges, and higher cost of low-sulfur fuel than marine oil.

The article reports on plans to reduce sulfur oxide emissions by ships using high-sulfur content fuel.

The article reviews the ship-emission monitoring system Marsic from producer of sensors and sensor systems Sick.
