Surface-wipe lead loading was measured at various locations in the homes of 31 boat-caulkers and 31 location-matched controls to identify factors associated with household lead contamination. Data were obtained by observation checklist and questionnaire. Lead loading was significantly higher in caulkers' than in control households. Median lead loadings (in microg/ft2) of various locations in caulkers' homes were windowsill, 43.9; exterior entrance, 9.5; interior entrance, 21.1; living room floor, 9.8; and bedroom floors 15.6. Corresponding levels in control homes were all less than 0.2 microg/ft2. Regression modeling indicated that lead loading was higher in caulkers' homes that were closer to a boat-yard, in which the caulker had a longer duration of boatyard work, and in which there were no children aged under 6 years resident. Exterior and interior entrance and living room floors had lower lead loading than windowsills. However, bedroom floors had significantly higher lead loading, similar to windowsills.
在31名船用填缝工和31名位置匹配的对照家庭的住所中的不同位置测量表面擦拭铅负荷，以确定与家庭铅污染相关的因素。数据通过观察清单和问卷获得。填缝工家庭的铅负荷显著高于对照家庭。填缝工家庭不同位置的铅负荷中位数（以微克/平方英尺计）为：窗台43.9；外部入口9.5；内部入口21.1；客厅地板9.8；卧室地板15.6。对照家庭的相应水平均低于0.2微克/平方英尺。回归模型表明，在距离造船厂较近、填缝工在造船厂工作时间较长且没有6岁以下儿童居住的填缝工家庭中，铅负荷较高。外部和内部入口以及客厅地板的铅负荷低于窗台。然而，卧室地板的铅负荷显著较高，与窗台相似。
