Volcanic Air Pollution - Photos Showing Vog and its Effects on Air Quality

Top Right Solid Corner

Vog is unpleasant to anyone, and can cause health problems that range from irritated eyes, skin and lungs. It can cause lung diseases such as asthma, lung cancer, and bronchitis. Lungs can be permanently damaged after long exposure to vog. The amount of damage depends on how much vog the lungs have been exposed to and how sensitive the lungs are. Vog can irritate your eyes, nose, skin, throat, tissues, and mucous membranes due to the vog particle’s small size. Vog can also cause acid rain which contaminates rainwater catchments system. For people with asthma and other respiratory problems, the effects are much more serious, causing a tightening of the airways in the lungs and making it very difficult to breathe.  A number of strategies can be used to minimize exposure to vog’s irritations: when possible, stay indoors with windows and doors closed and sealed. Use an air conditioner - it will condense water out of the indoor air and, in doing so, will remove the particulate sulfur compounds and acid gases from indoor air.  When working outdoors, you can greatly reduce your exposure to the sulfur compounds in vog by using a vinyl or rubber gas mask that’s fitted with cartridges rated for acid gases and particulates: many welding supply shops, and even some hardware stores, stock these items.  If you have asthma or other respiratory conditions, keep your medication refilled and use your daily medication as prescribed.  Have your emergency or evacuation medications available.  Avoid physical activity such as brisk walking or exercise. Drink liquids to avoid dehydration. If you are having asthma symptoms such as trouble breathing, increased coughing or chest tightness, contact your doctor or seek medical assistance. If you live on the island of Hawai‘i, you should check for county civil defense advisories and consider leaving the area. 

Vog and volcanic gases also effect livestock and agriculture. The Hawaii Department of Agriculture advises ranchers in areas downwind of the volcano to closely monitor the health of their livestock.  Ranchers should be on the look out for eye infections and gastrointestinal and respiratory problems in livestock.  Also, the livestock's ability to withstand being moved across distances and handled may be reduced due to abnormal air quality.   Ranchers should also ensure that an adequate supply of clean water is available.  A protected water supply is strongly advised.  Ranchers should also increase monitoring of watering troughs and cleaning of drinking vessels according to the degree of ash fall experienced in the area.   In addition, ranchers are advised to consult with their veterinarians regarding mineral supplements, particularly due to the higher than normal sulfur levels that may be expected with ash fall.  Sulfur dioxide in the volcanic emissions may deplete livestock of selenium and other minerals essential to animal health.  

Ash fall can have serious detrimental effects on agricultural crops depending on ash thickness, the type of growing condition of a crop and timing and intensity of subsequent rainfall.  There is little that can be done to protect field crops from ash fall.  Harvested crops should be thoroughly washed prior to consumption.   Overhead irrigation of greenhouse nursery stock may be helpful to wash away ash and residue and minimize chemical damage to flowers and foliage. Coffee and macadamia nuts, two of the Big Island's mainstays, appear unaffected. Koa and ohia trees are healthy, but eucalyptus leaves are turning brown, as are Asiatic lilies. Protea and orchids have been hard hit, as have market crops such as lettuce. The 2008 Farm Bill makes vog-affected farmers eligible for additional federal disaster aid. A survey of protea farmers conducted by the University of Hawaii showed eight farms on the Big Island expect to lose more than $360,000 in sales this year because of vog. Ten farms reported losing almost $550,000 since March, including lost production and the cost of replacing dead plants. The survey said 94 percent of the 33.4 acres the farmers have planted have been damaged.
