👉 Boats, especially those powered by diesel engines or other combustion-based systems, can emit various types of harmful fumes, primarily consisting of carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM), and volatile organic compounds (VOCs). Carbon monoxide is particularly dangerous as it is odorless and colorless, making it hard to detect until exposure leads to serious health issues. Nitrogen oxides contribute to air pollution and can form smog, while particulate matter can cause respiratory problems and other health complications. VOCs, which include a range of chemicals, can also pose health risks and contribute to environmental degradation. Proper maintenance and the use of cleaner technologies can help mitigate these emissions.
