Question

Anthracosis is caused by
A. Iron dust
B. Coal dust
C. Cane fibre
D. Silica

Answer 1

Hint: “anthracosis” the word “antrac” means coal or carbon and osis means condition.

Complete Answer:
A. Iron dust- Pulmonary siderosis is lung disease caused by repeated exposure to fine iron particles.

B. Coal dust- Accumulation of cola dust or carbon particles in the lungs causes anthracosis. This mild pneumoconiosis can be caused by repeated exposure to highly polluted areas, or inhaling smoke. Mostly it is asymptomatic in nature and falls under the initial stages of black lungs. Symptoms- Some of the early symptoms of the disease are breathing difficulty, cough and phlegm

C. Cane fibre- Bagassosis is also a lung disease caused from inhalation of the fine particles of the cane sugar (Bagasse). This disease leads to lung inflammation and was first discovered in India.

D. Silica- Silicosis or pulmonary fibrosis, a disease in which permanent scarring of the lung tissues are caused.

Hence correct answer is option B.

Note: (CMDLD)- coal mine dust lung disease, Anthracosis, silicosis, dust pneumoconiosis fibrosis and chronic obstructive pulmonary disease. CMDLD are a range of diseases which are caused in coal mine workers on long term exposure to fine particles of carbon, silica, red iron and other minerals.
