在墨西哥州南部瓦哈卡州的一个陶瓷民间艺术工作者社区进行了铅中毒风险研究，在那里，低温铅陶瓷制品的制造是家庭传统，通常是唯一的收入来源。变量，如家庭特征，职业和铅暴露的危险因素进行了探讨。研究参与者的平均血铅浓度为43.8 mug/dl（范围= 8.4-99.6 mug/dl），超过了世卫组织规定的40 mug/dl的标准，超过这个浓度会加速肾损伤。多变量回归分析显示，高血铅浓度的最佳预测因素为：职业（P < 0.0001）、性别（P = 0.0002）和使用釉面粗陶器（P < 0.0001）。该模型解释了研究组中18%的血铅变异。接触似乎主要与陈旧的陶器制造技术和生产场地普遍存在的高度污染有关，在大多数情况下，生产场地是他们的生活区。因此，这影响到整个社区的铅含量。
Lead intoxication risks were studied in a community of ceramic folk art workers in Oaxaca, a southern state of Mexico, where the manufacture of low-temperature lead ceramic ware is a family tradition and often the only source of income. Variables such as household characteristics, occupation, and lead exposure risk factors were explored. Study participants' mean blood lead concentration was 43.8 mug/dl (range = 8.4-99.6 mug/dl), which is over the WHO guideline of 40 mug/dl for removing workers from exposure and is the concentration over which renal damage is accelerated. Best predictors for high blood lead concentrations by multivariable regression analysis were: occupation (P < 0.0001), gender (P = 0.0002), and the use of glazed stoneware (P < 0.0001). This model explained 18% of blood lead variation among the study group. Exposure appears to be primarily associated with antiquated pottery manufacturing techniques and the high degree of contamination prevailing at the production sites, which in most cases are their living quarters. This consequently affects the lead levels of the entire community.
