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

SWOT Anal ysi s

Opportunity: Global concern Strong supportive network Low number of target population Alternative materials and other technical

preventive measures are available

SWOT Anal ysi s

: Lack of policy support? - Being againstby pro asbestos local and i

nternational industries Economic burden No public awareness

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
