[Occupational exposure to carcinogens: analysis of the application of the CAREX information system to Catalonia].

OBJECTIVE

The objective of this study is to estimate occupational exposures to human carcinogens in Catalonia in 2009, taking as a reference the CAREX ESP 2007 information system, and to evaluate the suitability of extrapolating these data to Catalonia.

METHODS

The reference population is the number of people registered with the Social Security system in Catalonia in 2009. Carcinogens considered are those which the International Agency for Research on Cancer (IARC) classified into groups 1 and 2A and are related to occupational exposures. The exposure prevalences from the CAREX ESP 2007, adapted to the Catalonian Industrial Classification (CCAE 09), were used. Technical survey reports from the Occupational Safety and Health Centers of the Catalonian local government, and related databases were consulted.

RESULTS

The most frequent occupational exposures to human carcinogens were solar radiation, crystalline silica, diesel exhaust, radon and wood dust, although based mainly on data not considered adequate for extrapolation to Catalonia. Around 217 exposure situations for 25 carcinogens, not previously considered in CAREX ESP 2007, were identified.

CONCLUSIONS

The estimated number of workers exposed to human carcinogens in Catalonia in 2009 based on the CAREX ESP 2007 system could differ from the real situation. Development of a CAREX CAT system that incorporates exposure data from Catalonia is recommended.
