For Volcanic Dust danger to human health

The eruption of the volcano is an event that we can not refuse, many losses, even until the victim died. Volcanic eruptions bring the economic, social, until the health, caused by a variety of materials of dust and gas, which is removed from the earth.

In this paper further discusses the dangers of volcanic ash, for the health of the human body, in the affected area of the volcano eruption.

When the volcano erupted, usually spouting water vapor (H2O), carbon dioxide (CO2), sulfur dioxide (SO2), hydrochloric acid (HCl), hydrofluoric acid (Hf), and volcanic ash into the atmosphere. The volcanic ash is less than 2 micro meters, contains such as silica, minerals and rocks. The most common elements are sulfate, chloride, sodium, calcium, potassium, magnesium, and fluoride. There are also other elements such as zinc, cadmium, and lead, in lower concentrations.

According to The International Volcanis Health Hazard Network, in general, volcanic ash causes, human health problems, such as acute respiratory disorders, disorders of vision, irritation of the skin, and mechanical disruption due to volcanic ash.

Acute respiratory distress

Very fine dust particles can enter the lungs during breathing. It makes a healthy person just hard to breathe. Early signs of respiratory problems due to exposure to volcanic ash are:

~ Irritation of the respiratory tract, characterized by sneezing and discharge of mucus/ cold

~ Irritation in the throat, sometimes accompanied by a dry cough

~ In patients with respiratory diseases such as bronchitis and asthma, volcanic ash causes more serious illness, with signs of acute bronchitis for several days, such as a dry cough/ phlegm, and shortness of breath

Bake -term exposure to volcanic ash, can cause serious lung diseases. Volcanic ash contains crystalline silica, in high concentration over the years, causing various health problems.

In patients with asthma, bronchitis, emphysema, and heart problems, those most at risk. Very fine ash particles can irritate the respiratory tract, causing contraction of the respiratory muscles making it difficult breathing. The ash also causes the lining of the respiratory tract, produce more secretions, which can make someone coughing and breathing heavy. In children, can suffer from coughing and tightness in the chest. Some people who do not have asthma, may experience asthma symptoms after volcanic ash, especially if it is too long to be outdoors.

Disturbances in vision

Eye irritation is a common effect, volcanic ash particles that form sharp pointy, when entering the eye can injure the cornea, and make red eye. Users of soft lenses, it is better to take it off to prevent corneal abrasion. Disorders that often arise in the eye due to the volcanic ash of which

~ Feel eye smth

~ Eye pain, itching, burning, redness, feels uncomfortable

~ Shed tears, sticky, and remove dirt dusky yellowish

~ There was a corneal abrasion/ scratches on the cornea

~ Acute red eye, eyelids become swollen, because the process of inflammation, eye burning, be sensitive to light, and decreased vision

Skin irritation

Body skin can also become irritable from volcanic ash, though rarely to serious. In some cases, the acidic volcanic ash, can cause :

~ Red rash on the skin

~ The incidence of red spots on the skin

~ Itching experience in skin

~ The infection can appear as skin scratch

Mechanical disruption

Mechanical disruption of volcanic ash for example, in transport where visibility is reduced, which can lead to accidents, ash can also contaminate water, so the water consumption of unhygienic, and so on

Tips to prevent disruptions due to volcanic ash :

~ Use a mask or wet handkerchief to cover the nose

~ Use goggles to avoid eye of the entry of dust particles

~ Remove soft lenses/ contact lens for a while

~ Use long-sleeved shirts and long pants, so that the skin does not come in direct contact with volcanic ash

~ Wash skin exposed to volcanic ash, with running water and soap
