In today's industrial environment, several high-risk occupational diseases pose serious threats to workers' health. These include pneumoconiosis, noise-induced hearing loss, benzene poisoning, lead poisoning, and carbon monoxide poisoning. The industries most affected are mining, auto repair, construction, packaging, and stone processing. Understanding the risks, prevention strategies, and treatment options for these conditions is crucial. To provide insight, this reporter spoke with experts from the Hainan Provincial Center for Disease Prevention and Health Care, who specialize in the diagnosis and health monitoring of occupational diseases.
**Pneumoconiosis**
Industries at high risk: Mining, stone processing, and construction.
Pneumoconiosis is a lung disease caused by long-term inhalation of dust particles, such as silica. Its primary symptoms include coughing, chest pain, shortness of breath, wheezing, and even hemoptysis (coughing up blood). In its early stages, the condition may not show clear symptoms, but over time, it can lead to chronic bronchitis and frequent lung infections. One of the most alarming aspects of pneumoconiosis is that it is irreversible and cannot be completely cured—only managed through medical care.
**Prevention Tips:**
Workers in high-risk industries should undergo regular health check-ups, including pre-employment, on-the-job, and post-employment screenings. For those working in dusty environments for extended periods, follow-up checks are essential. Personal protective equipment like dust masks, helmets, and air-supplied devices must be used consistently. Maintaining good personal hygiene, such as washing after work and changing clothes, also plays an important role in reducing exposure.
**Benzene Poisoning**
Industries at high risk: Paint manufacturing, auto repair, and luggage production.
Benzene poisoning occurs when workers are exposed to benzene, a common chemical in many industrial settings. It is particularly dangerous because it often affects small or family-run workshops with poor safety measures. Long-term exposure can lead to severe health issues, including reduced white blood cell counts, low platelet levels, and even leukemia or aplastic anemia.
**Prevention Strategies:**
Employers should replace benzene with safer alternatives where possible and improve ventilation systems to reduce exposure. Workers must wear appropriate protective gear, such as gas masks, and undergo regular medical check-ups. Awareness of symptoms like fatigue, dizziness, and easy bruising is essential for early detection and treatment.
**Noise-Induced Hearing Loss**
Industries at high risk: Furniture, textile, and metal stamping factories.
Prolonged exposure to loud noises can cause irreversible damage to hearing and affect other body systems, such as the nervous and cardiovascular systems. Annual physical exams are vital for identifying early signs of hearing impairment, such as tinnitus (ringing in the ears).
**Prevention Measures:**
According to national standards, workplace noise levels should not exceed 85 decibels. If they do, working hours should be reduced accordingly. Workers in noisy environments must use certified ear protection, such as earplugs and earmuffs. Regular occupational health screenings are also recommended. Early recognition of symptoms like ringing or muffled hearing can help prevent further damage.
Occupational diseases are a serious public health concern, especially in industries with high exposure risks. Employers and workers alike must take proactive steps to protect health and ensure safe working conditions. Awareness, proper training, and adherence to safety regulations are key to preventing long-term harm.
