Inhalation is a major route of exposure that occurs when an individual breathes in polluted air which enters the respiratory tract. Identification of the pollutant uptake by the respiratory system can determine how the resulting exposure contributes to the dose.
People who had dust pneumonia often died. [1] There are no official death rates published for the Great Plains in the 1930s. In 1935, dozens of people died in Kansas from dust pneumonia. [1] Red Cross volunteers made and distributed thousands of dust masks, although some farmers and other people in the affected areas refused to wear them. [1]
The health effects of particulate matters with different diameters are related to the length of those particles staying in the atmosphere and the locations of infection in the respiratory tract [27] Young children who are exposed to air pollution are extremely vulnerable. One reason they are more vulnerable is because the average breathing ...
The main exposure to UFPs is through inhalation. Owing to their size, UFPs are considered to be respirable particles. Contrary to the behaviour of inhaled PM 10 and PM 2.5, ultrafine particles are deposited in the lungs, [13] where they have the ability to penetrate tissue and undergo interstitialization, or to be absorbed directly into the bloodstream—and therefore are not easily removed ...
Because chlorine is a gas at room temperature, most exposure occurs via inhalation. Exposure may also occur through skin or eye contact or by ingesting chlorine-contaminated food or water. Chlorine is a strong oxidizing element causing the hydrogen to split from water in moist tissue, resulting in nascent oxygen and hydrogen chloride that cause ...
Despite lower respiratory effects among all children, there was a significant difference in health outcomes between children with pre-existing conditions and children without. [15] Children with pre-existing conditions were at greater risk that can likely be attributed to the greater disruption of care in the face of flooding and natural disaster.
Desert lung disease may be related to Al Eskan disease, a lung disorder thought to be caused by exposure to sand dust containing organic antigens, which was first diagnosed after the 1990 Gulf war. [57] The relative importance of the silica particles themselves and the microorganisms that they carry in these health effects remains unclear. [58]
There are two primary types of dust exposure in agriculture: inorganic and organic. Often the cause of allergy illnesses like asthma, organic dusts come from both plant and animal sources. Inorganic dust illnesses are non-allergic lung reactions that originate in the soil. [4] Asthma-like symptoms are linked to inorganic dust syndrome.
