â— What is pneumoconiosis? What are the legal pneumoconiosis in our country?
Pneumoconiosis is a chronic lung disease caused by prolonged exposure to dust particles in occupational environments. It leads to fibrosis in the lungs, which can severely affect respiratory function over time. This condition is classified as an occupational disease due to its direct link with work-related dust exposure.
In China, the "Clinical Catalogue of Occupational Diseases" officially recognizes 13 types of pneumoconiosis. These include silicosis, coal worker's pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestos pneumoconiosis, talc pneumoconiosis, cement pneumoconiosis, mica pneumoconiosis, potter's pneumoconiosis, aluminum pneumoconiosis, welder's pneumoconiosis, caster's pneumoconiosis, and other pneumoconiosis diagnosed based on established criteria. Among these, silicosis and coal worker’s pneumoconiosis are the most frequently reported cases in the country.
â— What are the most common types of pneumoconiosis in China?
According to long-term data from occupational health surveys and reports released by the Ministry of Health, silicosis and coal worker's pneumoconiosis remain the most prevalent forms of pneumoconiosis in China. These two conditions together account for approximately 90% of all diagnosed cases. The high prevalence is largely due to the widespread use of silica-containing materials in mining, construction, and manufacturing industries.
â— What are the clinical manifestations of pneumoconiosis patients?
The symptoms of pneumoconiosis typically develop gradually and may initially go unnoticed. However, as the disease progresses, patients often experience coughing, sputum production, chest pain, and shortness of breath. In some cases, wheezing or hemoptysis (coughing up blood) may also occur. These symptoms can be exacerbated by coexisting conditions such as chronic bronchitis or lung infections.
Early-stage pneumoconiosis may not cause significant coughing, but as the disease advances, the cough becomes more persistent and severe. Smokers tend to experience more intense symptoms due to the combined effects of smoking and dust exposure. Sputum production is often increased, especially in coal workers, where the sputum may appear dark and contain visible coal particles.
Chest pain is a common symptom among pneumoconiosis patients, particularly those with silicosis or asbestosis. The pain is usually non-specific and may vary in intensity, ranging from mild discomfort to sharp, stabbing sensations. Dyspnea, or difficulty breathing, tends to worsen as the disease progresses, and it can lead to complications such as pulmonary hypertension or cor pulmonale, which affects heart function.
