  1. a = average micronuclei frequency under active exposure. b = adjusted rate of hospital morbidity from respiratory diseases in children (Chapter X/ICD-10). * Correlation is significant at the 0.05 level (2-tailed). ** Correlation is significant at the 0.01 level (2-tailed). Data obtained in the dry and rainy period.
