Abstract

Blood, seminal plasma and spermatozoa lead concentrations were determined in Holstein (29 animals), Brown Swiss (14 animals) and Charoleux (11 animals) bulls aged 1-8 y. Blood concentrations were (mean +/- SD) 21.47 +/- 5.85, 18.71 +/- 6.60 and 23.27 +/- 6.75 ng Pb/ml respectively/each breed. Seminal plasma concentrations were 17.15 +/- 10.37, 13.62 +/- 10.10 and 14.03 +/- 11.31 ng Pb/ml, respectively. Spermatozoa concentrations averaged 74.93 +/- 48.10, 76.60 +/- 33.95 and 63.39 +/- 25.83 ng Pb/10(9) cells respectively. Age appeared to influence seminal plasma and spermatozoa lead levels, gradually decreasing in concentrations as the animals advanced in age.

摘要

测定了1至8岁的荷斯坦公牛（29头）、瑞士褐牛（14头）和夏洛莱牛（11头）的血液、精浆和精子中的铅浓度。各品种血液中的铅浓度分别为（平均值±标准差）21.47±5.85、18.71±6.60和23.27±6.75纳克铅/毫升。精浆中的铅浓度分别为17.15±10.37、13.62±10.10和14.03±11.31纳克铅/毫升。精子中的铅浓度平均分别为74.93±48.10、76.60±33.95和63.39±25.83纳克铅/10⁹个细胞。年龄似乎会影响精浆和精子中的铅含量，随着动物年龄的增长，其浓度会逐渐降低。
