Heavy metals exposure has been linked to severe health problems. In Mexico, the Monterrey metropolitan area (MMA) is considered one of the most polluted industrial regions. Because birds have been used successfully as environmental biomonitors, the levels of lead, cadmium, and arsenic in feathers of Great-tailed grackles (Quiscalus mexicanus) from two sites within and one site outside the MMA were determined. One hundred birds were captured, samples were analyzed by atomic absorption spectrometry. Ciudad Universitaria had the highest mean values of lead and cadmium, 11.91 ppm d.w. and 1.66 ppm d.w., respectively. This was at least, 10- and 8-times higher than the two other sample sites. We believe that using Great-tailed grackles as bioindicators in conjunction with air pollutants sampling from meteorological stations in Monterrey City could help in making decisions when applying environmental remediation measures as well as in the selection of places for housing, school and work among others.
重金属暴露已被证实与严重的健康问题有关。在墨西哥，蒙特雷大都市区（MMA）被认为是污染最严重的工业地区之一。由于鸟类已被成功用作环境生物监测器，因此测定了来自 MMA 内两个地点和一个地点外的大尾秃鹫（Quiscalus mexicanus）羽毛中的铅，镉和砷含量。共捕获了 100 只鸟，并用原子吸收光谱法对样本进行了分析。Universitaria 市的铅和镉含量最高，分别为 11.91 ppm d.w.和 1.66 ppm d.w.。这至少比其他两个采样点高 10 到 8 倍。我们认为，在对蒙特雷市气象站的空气污染物进行采样的同时，使用大尾秃鹫作为生物指标，可以帮助在采取环境补救措施以及选择住房，学校和工作等场所时做出决策。
