Job Exposure Matrix in Brazil and Silica and Benzene Exposure

SãoPaulo 06/05/22

Job Exposure Matrix in Brazil

First National JEM

Estimate the magnitude of occupational exposure to Silice in Brazil from 1985 to 2001.

(Ribeiro, PhD Thesis 2004)

Job Exposure Matrix - JEM

Estimation of the exposed according to the job occupation and economic sector

Database of employed workers informed annually by employers – RAIS- Around 47% of total workers

1. Classified Occupation

Job Title

The new version of the Brazilian Occupational Classification (CBO) takes as reference the latest version of the International Statistical Classification of Occupations - ISCO-88 (International Standard Classification of Occupations - CIUO-88).

CBO 4digits = 2.422 occupation.0

2. Clasified economic sector (industry)

Classification of Economic Activities:

Brazilian Classification of Economic Activity (CNAE) maintains the same pattern, aligning with the structure of the international classification.

International Standard Industrial (ISIC) and Statistical Classification of Economic Activities in the European Community (CNACE)

CNAE 2 digits = 25 economic sectors

3. Ocupation

4. Code the exposure

60.550 cells

Two experts classified silica exposure in four categories, according to a presumed weekly frequency of exposure.

• No Exposure: Low then 1% of work journey

• Possible exposure: from 1 to 5%

• Probable exposure: from 5 to 30%

• Definitive exposure: more than 30% work journey

Sample of 5 economic sectors

Accuracy -> sensitivity and specificity tests

Reliability -> Testing of the internal consistency of the quantified Inter-rater reliability based on Cohen’s Kappa

5. Workers employed in 1995.

Employed workers :

38% Women

Exposures to any frequency of silica

Cancer Exposure – Concepts

​

1. Occupational Exposure: is one in which the worker, due to the work process, comes into direct or indirect contact with carcinogens present directly or potentially in the work environment/process.

​

• Exposure occurs in the work environment regardless of defined exposure limits. It allows the use of occupation as an approximation of exposure for epidemiological purposes.

9. Classification Criterion

​

​

Exposed – Experts agree that this occupation or industry is exposed

​

Not Exposed - Experts agree that this occupation or industry is not exposed

​

Conditionally exposed – There is evidence of exposure for the occupations, but there is no certainty for the industry.

There is exposure for the industry

but not sure for any occupation.
