Report Says Air Quality On Cruise Ships Could Harm Your Health

CNN:–  Cruise ships generate high levels of air pollution that could endanger the health of passengers, staff and port communities, according to an undercover report released Thursday.

On the decks of the four Carnival Corp. cruise ships studied over a two-year period, concentrations of particulate matter measured were “comparable to concentrations measured in polluted cities, including Beijing and Santiago,” according to Ryan Kennedy, author of the report and an assistant professor at Johns Hopkins University Bloomberg School of Public Health.
Ship exhaust contains harmful constituents, including metals and polycyclic aromatic hydrocarbons, many of which have toxic, possibly cancer-causing properties, Kennedy said: “It’s dangerous it’s not a healthy thing for us to be exposed to.”
The vessels on which Kennedy took measurements were Carnival Liberty sailing from Florida to the Bahamas; Carnival Freedom sailing from Texas to the Caribbean; Holland America MS Amsterdam sailing from Vancouver to Los Angeles; and Princess Cruises Emerald Princess sailing from Los Angeles to Mexico. (Holland American and Princess Cruises are subsidiaries of Carnival Corp.)
Without the knowledge of the company or ship staff, Kennedy took measurements using a P-TRAK Ultrafine Particle Counter when the ships were docked as well as when moving at sea.
Consistently, Kennedy said, the highest average readings of particulate matter (PM) concentration were found behind the smokestack at the back of the ship. The equipment he used measured particles with sizes between 0.02 and 1.0 micrometers, considered ultrafine and fine PM.
“What Dr. Kennedy found on board was shocking,” said Kendra Ulrich, senior shipping campaigner at, the international environmental organization that commissioned the report. She noted that the stern area — the back of the ship — may be where running tracks, swimming pools or lounge areas are located, so both passengers and cruise line employees may be spending considerable time in these areas.
“ is campaigning to get Carnival Corp. to stop using heavy fuel oil,” Ulrich said. “What this industry giant does can have a huge effect in setting standards for the rest of the industry.”
Carnival said in a statement that it coordinates its cruises with “national and international regulatory bodies like the [US Environmental Protection Agency] to insure the utmost safety of our guests and crew” and that tests of the air quality on its ships “meet or exceed every requirement.”
“Independent testing on our funnels — which is the area where the exhaust originates — further validates our claims,” the company said. “This particular organization, for fund raising purposes, is constantly in search of a problem in our industry even if it has to create fake tests that really have no scientific basis.”
Megan King, a spokeswoman for the Cruise Lines International Association, an industry advocate, said that “globally, the cruise industry has already invested $1 billion in new technologies and cleaner fuels to significantly reduce ships’ air emissions.”
Worldwide, more than 30 million cruise passengers — the major share residents of the United States — are expected in 2019, according to the association. The multibillion-dollar industry also provides jobs to upward of 1 million full-time equivalent employees, including thousands who work on the ships themselves.
An unrelated 2007 study found that “annually, oceangoing ships are estimated to emit 1.2-1.6 million metric tons (Tg) of particulate matter.”
King added that the cruise industry is “only a small part of this issue” and that container shipping, as well as other types of tourism, also contribute to marine air pollution.
Kennedy noted that “ultrafine particles or even nanoparticles” are a “great concern for health.” If an ultrafine particle is made up of something toxic, the likelihood of it interacting with a cell in your body is greater. Although anyone exposed to these particles is affected, people predisposed to cardiovascular disease or with pulmonary conditions, including asthma, are most at risk.
“We know heavy fuel oil has harmful constituents in it,” said Ulrich of “We know that there are higher rates of asthma among children in port communities.”


  1. Me no have momies for big fancy boat,but now that you say the boat can kill people Me no going on boat,staying at home with girlfriend,I going to tell her to wash mouth before we kiss, me no want to die from nonaparticles that I suspect she carries in her mouth and other parts of bodie.
