Nghiên cứu thực trạng tiếp xúc với bụi và tiếng ồn công nghiệp của công nhân cảng lancang ấn độ_Occupation Health Status of Workers Exposed to Dust and Industrial Noise in a City along Lancang River Background With the economical development of west Yunnan along lancang river, More and more industries were introduced. Workers exposed to dust and industrial noise can cause silicosis and occupational noiseinduced deafness. To find occupational contraindication and suspected occupational disease as early as possible is significantly for occupation health surveillance .Aims: To understand health status of workers exposed to dust and industrial noise in Baoshan city, supply references to industries in Lancang river areas for occupation health surveillance. Method: The total of 1203 workers with silicious dust, cement dust ,tobacco dust and noise occupational hazardous factors were randomly sampled in Baoshan city. Occupation health examination was conducted to subjects.

Background:

With the economical development of we

st Yunnan along lancang river, More and m ore industries were introduced

Workers exposed to dust and industrial noise can cause silicosis and occupational noise-induced deafness

suspected occupational disease as early as possible is significantly for occupation healt

h surveillance

Aims:

To understand health status of workers exposed to dust and industrial noise in Baos han city, supply references to industries in Lancang river areas for occupation health s urveillance

Method:

The total of 1203 workers with silicious dust, cement dust ,tobacco dust and noise occupational hazardous factors were rando mly sampled in Baoshan city Occupation h ealth examination was conducted to subject s

High kilo-voltage chest radiograph was used as a screening measurement for

silicosis Diagnosis of silicosis was undertaken using occupation health surveillance standard (GBZ188-2014)

a screening measurement for hearing loss Diagnosis of hearing loss was undertaken u sing occupation health surveillance standar

Conclusion:

1.Workers in highlighted occupational disease preve ntion area in Baoshan have a high prevalence of occ upational contraindication and hearing loss.

2.Noise was the main occupational hazardo

us factors in this area

3 Enterprises and companies should enhance protection measurement and improve the working environment, especially to protect workers from noise more than 85 dB and working more than 5 years.

4 As the core of occupational disease protection, En terprises should enhance occupational health educat ion and health promotion Especially pay attention t

o workers at earlier working year
