Deutsch: Lunge / Español: Pulmones / Português: Pulmão humano  / Français: Poumon / Italiano: Polmone
The lung is the essential respiration organ in many air-breathing animals, including most tetrapods, a few fish and a few snails. In mammals and the more complex life forms, the two lungs are located near the backbone on either side of the heart. Their principal function is to transport oxygen from the atmosphere into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere.

In the environmental context, "lung" generally refers to the respiratory system, which includes the lungs and other organs involved in breathing. Exposure to environmental pollutants and other hazards can have significant impacts on lung health, contributing to respiratory diseases and other health problems. Here are some examples of "lung" in the environmental context:

  1. Air pollution: Exposure to air pollutants such as particulate matter, ozone, and nitrogen oxides can cause inflammation and damage to the respiratory system, contributing to respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD).

  2. Radon: Radon is a naturally occurring radioactive gas that can seep into homes and other buildings. Exposure to radon gas can increase the risk of lung cancer.

  3. Asbestos: Asbestos is a group of naturally occurring minerals that were commonly used in construction materials until the health risks were discovered. Inhalation of asbestos fibers can cause lung diseases such as mesothelioma and asbestosis.

  4. Secondhand smoke: Exposure to secondhand smoke can have negative impacts on lung health, increasing the risk of respiratory diseases and lung cancer.

  5. Occupational hazards: Workers in certain industries may be exposed to hazardous substances such as silica, coal dust, or diesel exhaust, which can cause lung diseases such as silicosis and black lung disease.

  6. Climate change: Climate change can have impacts on air quality, leading to increased air pollution and the potential for negative impacts on lung health.

In summary, the term "lung" in the environmental context is often used to refer to the respiratory system and the impacts of environmental hazards on lung health. Understanding and mitigating these impacts is important for protecting public health and promoting a sustainable environment.
