Do you know the air pollution on the marine deck machinery?

148 Published by admin 5月 15,2019

A recent study found heavy air pollution on the decks of four carnival cruise ships.The study sparked a new debate about the role of the cruise industry in tackling climate change.

Despite recent efforts by the cruise industry to reduce emissions and reduce its environmental impact, a new report has reopened the debate about how much work remains to be done.

The shipping industry is estimated to cause 15 percent of nitrogen oxides and 8 percent of sulfur gases worldwide, and the new document has sparked more outrage because it reveals high levels of particulate pollution, defined as' small solids or droplets suspended in the air. 'And these discharge basically come from. Marine deck machinery

Titled "air pollution survey on deck of 4 cruise ships," the results were compared to pollution levels in cities such as Beijing and San Diego.

Unsurprisingly, the Numbers have been severely challenged by fiesta - the owner of the four ships under investigation - along with other industry stakeholders, who have hit back at the "inaccurate" and "absurd" reports, claiming its scientific basis is poor.

Worse than a bad day in Beijing

While this is not the first report to challenge the environmental impact of the industry - nor is it the only one to be challenged."We know this is going to be a very eye-opening story, but it could also be a story that is questioned by the cruise industry," said one.

For this reason, the report's lead authors took additional precautions when conducting a secret investigation of four marine deck machinery.

This means collecting samples in the ship's three most crowded areas - one at the front and two behind it - for 15-20 minutes while the ship is at sea, thus reducing environmental pollution.

Dr Kennedy also decided to publish all the data he had so that it could be independently verified and reviewed (results of independent verification have not been published to date).Therefore, the collected data can still participate in the competition.

The ratings were measured on four different carnival cruises, carnival, the Dutch American line and princess cruises.

The results were shocking, "ulrich concluded."In some cases, where people might be, the air pollution in the stern is as bad or worse than the bad days in Beijing."

The report's data also revealed a high level of harmful components in ship exhaust, including metals and polycyclic aromatic hydrocarbons (PAHs).
