Introduction

No asbestos mine in the country Only import for manufacturing Only chrysotile is allowed to use (crocidolite was banned in 1992

and amosite was banned recently)

Estimation of cases of asbestos-related diseases in

Thailand Tossavainen indicated a significant linear

correlation between consumption of asbestos and the number of mesothelioma cases.

Calculating as follows:Y= 6.82x amount of consumption (25-30 years

ago)+0.43Y= No. of cases/million/yearAmount of consumption= No. of Kg/capita/year

(2.5 Kg/cap/y)Y=(6.82x2.5)+0.43=17.5 cases/million/yearTotal new cases/year=17.5x63= 1,103 cases

Conclusions

Consumption of asbestos in Thailand is very high and the trend shows its in

creasing - Asbestos related diseases will becom

e more important public health issue Several measures need to be implem

ented urgently Strategy of asbestos ban is the best p

olicy but an achievement of this goal i s still a long way
