Pollution from marine shipping causes approximately 60,000 premature cardiopulmonary and lung cancer deaths around the world each year, according to a report scheduled to appear in the Dec. 15 issue of Environmental Science and Technology, the journal of the American Chemical Society.
The report benchmarks for the first time the number of annual deaths caused globally by pollution from marine vessels, with coastal regions in Asia and Europe the most affected.
Conducted by James Corbett of University of Delaware and James Winebrake from Rochester Institute of Technology, the study correlates the global distribution of particulate matter—black carbon, sulfur, nitrogen and organic particles—released from ships’ smoke stacks with heart disease and lung cancer mortalities in adults. The results indicate that approximately 60,000 people die prematurely around the world each year from shipping-related emissions.
Under current regulation, and with the expected growth in shipping activity, Corbett and Winebrake estimate the annual mortalities from ship emissions could increase by 40 percent by 2012.Corbett and Winebrake’s results come in the midst of current discussions by the International Maritime Organization to regulate emissions from ships.
“This study will help inform policymakers about some of the health impacts associated with ship emissions and the long range transport of those emissions to population centers,” says Winebrake, chair of RIT’s Department of Science, Technology and Society/Public Policy. “We now have a benchmark by which we can begin to evaluate the benefits of emission reduction policies.”
Annual deaths related to shipping emissions in Europe are estimated at 26,710, while the mortality rate is 19,870 in East Asia and 9,950 in South Asia. North America has approximately 5,000 premature deaths, concentrated mostly in the Gulf Coast region, the West Coast and the Northeast, while the eastern coast of South America has 790 mortalities.Ships run on residual oil, which has sulfur content thousands of times greater than on-road diesel fuel. “Residual oil is a byproduct of the refinery process and tends to be much dirtier than other petroleum products,” Winebrake says.
“We needed to know what the benefits are of cleaning up this fuel,” he explains. “Now we can evaluate the human health impacts of policies to require low-sulfur fuels for the shipping industry or that require ships to put emissions control technology on their vessels. Our study will help inform this policy debate.”Up until recently, researchers had little information with which to work; emissions data for marine vessels had to be linked with data tracking the movement of these vessels around the world. In their report, Corbett and Winebrake mapped marine pollution concentrations over the oceans and on land, estimating global and regional mortalities from ship emissions by integrating global ship inventories, atmospheric models and health impacts analyses.
The focus on long-term exposure to particulate matter in this study does not extend to impacts on children or other related health issues such as respiratory disease, asthma, hospital emissions and the economic impact of missed workdays and lost productivity.“Our work will help people decide at what scale action should be taken,” says Corbett, associate professor of marine policy at University of Delaware. “We want our analysis to enable richer dialogue among stakeholders about how to improve the environment and economic performance of our freight systems.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
