White cell and differential counts were studied in school children living at Amman (group A), Dead Sea natives (group B), and residents of the Dead Sea area who originated from different areas (group C). A total of 159 subjects from group A, 146 from group B, and 38 from group C, were studied. Significant leukopenia was observed in group B, as compared with groups A and C (p less than 0.005). This was due to selective neutropenia in group B (p less than 0.005). Careful analysis revealed that this difference was genetic and not environmental. Living at 390 m below sea level does not affect the white cell or the differential count.
对居住在安曼的学童（A组）、死海本地居民（B组）以及来自不同地区的死海地区居民（C组）进行了白细胞及分类计数研究。共研究了A组的159名受试者、B组的146名受试者和C组的38名受试者。与A组和C组相比，B组观察到明显的白细胞减少（p<0.005）。这是由于B组存在选择性中性粒细胞减少（p<0.005）。仔细分析表明，这种差异是遗传的而非环境因素造成的。生活在海平面以下390米处不会影响白细胞或分类计数。
