O1C.4 Cancer incidence among lead-exposed workers in two countries

Excess cancer incidence among workers exposed to fluoride.

Mortality and cancer incidence among secondary lead smelter workers.

OBJECTIVES To examine the mortality pattern and the cancer incidence in a cohort of long term smelter workers exposed to lead. METHODS The cohort consists of 664 male lead battery workers, employed for at least three months in 1942-87. From 1969 the values of all blood lead samples repeatedly obtained from these workers every two to three months, have been collected in a database. The expecte...

Eryptosis in lead-exposed workers.

Eryptosis is a physiological phenomenon in which old and damaged erythrocytes are removed from circulation. Erythrocytes incubated with lead have exhibited major eryptosis. In the present work we found evidence of high levels of eryptosis in lead exposed workers possibly via oxidation. Blood samples were taken from 40 male workers exposed to lead (mean blood lead concentration 64.8μg/dl) and no...

Extended follow-up of cancer incidence in fluoride-exposed workers.

ed above, the letter below from one of our readers was submitted on June 10, 2004 to the Journal of the National Cancer Institute but was declined for publication. This journal [J Nat Cancer Inst] recently reported increased cancer incidence among cryolite industry workers.1 These findings merit comment on the implications for workers in other industries, particularly the aluminum industry. The...

Incidence of renal stones among cadmium exposed battery workers.

The health effects of occupational exposure to cadmium were studied in a group of 902 workers employed for at least one year in a Swedish battery factory between 1931 and 1982. Data on air cadmium concentrations for different periods were combined with company employment records to obtain individual cumulative exposure estimates. A questionnaire including questions on the occurrence of kidney s...
