The association with welding,soldering and the welding industry is strong and suggests a need for further work.This is despite the small numbers studied,thus making most industrial or occupational exposures too limited to draw conclusions or detect associations.Perhaps the most obvious candidate from the welding,soldering exposure for a common toxin would be lead.Other suggestions of risk were seen for paint or pigment manufacture, shipbuilding,electric plating,and the dairy industry.The degree of association for these,while high,is not statistically significant and suggests that there may be one or more environmental toxins common to these industries that need more precise measurement. |
