Air Pollutants
In the maritime context, air pollutants refer to harmful substances released into the atmosphere by ships and other marine vessels. These pollutants can have significant impacts on both the environment and human health. The primary sources of air pollutants in the maritime industry are the combustion engines of ships, which burn fossil fuels and release a variety of harmful substances into the air. These include sulfur oxides (SOx), nitrogen oxides (NOx), particulate matter (PM), and greenhouse gases such as carbon dioxide (CO2). SOx and NOx can contribute to acid rain and eutrophication, which can harm aquatic ecosystems. PM can affect air quality and human health, particularly in coastal areas and port cities. Greenhouse gases contribute to global warming and climate change. The International Maritime Organization (IMO) has established regulations to limit the emission of these pollutants from ships, including standards for fuel quality and engine performance.
