||Mortality and cancer incidence among alachlor manufacturing workers 1968-99
||Aug. 2004, Vol.61, No.8, p.680-685. 20 ref.
||Alachlor is the active ingredient in herbicide formulations used widely on corn, soybeans and other crops. It has been found to cause nasal, stomach, and thyroid tumours in rodent studies, however at levels that are much higher than likely human exposures. This study was carried out to evaluate mortality rates from 1968 to 1999 and cancer incidence rates from 1969 to 1999 among workers at an alachlor manufacturing plant. Worker mortality and cancer incidence rates were compared to corresponding rates for the Iowa state general population. Analyses addressed potential intensity and duration of exposure. There were no cancers of the types found in toxicology studies and no discernible relation between cancer incidence for any site and years of alachlor exposure or time since first exposure. These findings are significant considering that these workers had chronic exposure during extended manufacturing campaigns, while use in agriculture is typically limited to a few days or weeks each year.
