Preparing for Arctic Traffic

By: Jessica Robertson

With the changing climate melting ice in the Arctic Ocean, traffic, both tourism and industry related, steadily increases in the northern realm of our planet. The increased travel brings to light the unpreparedness of the region for managing the risk of an oil spill.

            Other highly trafficked water routes have systems in place for managing the occasional oil spill. In the Arctic, fewer systems are in place and the extreme conditions make it a difficult operation to even respond to a spill. Due to the extreme weather, enormous geographic area, beautifully diverse ecosystem, and limited resources for operation and communication in some areas, many changes would need to be instated to prepare for a spill response that compares to a response in easier waters.

            Decision makers are working toward an international plan that would better prepare and protect the Arctic as the traffic pattern expands. A proper response plan must include a number of techniques to span the vast number of possible environmental situations. No single method can begin to apply in all possible spill scenarios.  More equipment, better communication, a larger workforce, and increased safety measures are just a few of the items on the wishlist for a project of this scale.

            Studies are underway to assess the possible effects of dispersants and oil on some Arctic marine species. The findings of these studies will inform decisions on how to manage spills in the future. Alaska has yet to grant approval for the use of chemical dispersants to address a spill, preferring in situ burning as a cleaner and safer method for their environment. It is yet to be seen what methods will be placed in the Arctic toolbox, but hopes are high that the environment will remain safe in their care. 

Not So Sweet Dreams

We are all well aware of the constant presence of chemical compounds in our surroundings. Because of their prevalence, it can be a natural reaction to trust in their safety; anything so common shouldn’t be a threat. A team of environmental engineers from Cockrell School of Engineering has recently investigated a frightening topic that had never previously been considered. Looking at the foam padding in new crib mattresses, the team recorded high levels of volatile organic compounds (VOCs) emitted from the material. Sometimes found in products like household cleaners and sprays, VOCs include chemicals like formaldehyde, benzene, and acetone, among others. No conclusive studies have shown the definitive health effects of exposure to the chemicals, although they are regarded as dangerous chemicals.

By comparing polyurethane foam and polyester foam in a group of both new and old crib mattresses from ten different manufacturers, the researchers found that the new crib mattresses release VOCs at a level four times higher than old crib mattresses, and a baby’s body heat triggers VOCs to be emitted. Frighteningly, the VOC emission levels were found to peak in the baby’s immediate breathing zone. The VOC levels that the new crib mattresses emit are comparable to some other potentially hazardous household materials, including laminate flooring and wall coverings.

Considering that infants are highly susceptible to pollutants and that infants can spend over half of their time asleep in their cribs, the presence of these chemicals within the mattress material is shocking. The findings did not shock some of the experts, saying that the levels of VOCs, while surprising, were not high enough to cause true alarm for the safety of children. However, those experts deem this very valuable research and worthy of further investigation to assure safety. 

It is not recommended to replace new mattresses with older mattresses that contain banned substances, like flame-retardants; reusing an older crib mattress that is known to have no banned substances may reduce infants’ exposure. To reduce levels of VOCs in new mattresses, a period of airing-out may help. Keep an eye on this issue to make sure your children are protected.
