摘要：Introduction: Though the trace element strontium's (Sr) exact role in health remains unknown, at certain levels, it is toxic and, given the body's low thresho ld for Sr, has been cited to cause nervous disorders. At d ifferent stages of the life cycle, organisms vary in t heir abilit y to discriminate Sr and calcium, which can cause age-related differences in gastroint estinal absorption. Though data regarding the effects o f such absorption remain limit ed, it can reportedly impact health, the immune system, and chromosomal aberration. Purpose: To investigate and co rrelate levels of Sr co ncentration and any health problems at certain levels among auto mobile workers. Materials and methods: The blo od of 41 auto mobile workers and 26 healt hy controls o f t he Ko lkata regio n was co llected and whole blood Sr concentratio n estimated by the energ y dispersive X-ray fluorescence (EDXRF) t echnique. Results: Automobile workers showed significant ly (p <0.001) higher blood SR levels than cont rols from the same area, despite similar dietary habits and drinking- water quality. Conclusions: Auto mobile workers are exposed to different pollutant s that can harm their healt h, and a trace element imbalance of Sr and its elevat ed concentratio ns in the blood may cause different health complicatio ns
