Faecal elimination of lead and cadmium in 16 subjects who changed from a mixed diet to a lactovegetarian diet has been studied. The faecal weight increased significantly following the change to the vegetarian diet, partly because of increased water content. There was a large inter-individual variation in faecal elimination of lead and cadmium during both the mixed-diet period (range 14 to 118, median 31 micrograms Pb/day; range 4.5 to 21, median 12 micrograms Cd/day) and the vegetarian diet period (range 19 to 136, median 42 micrograms Pb/day; range 6.1 to 24, median 14 micrograms Cd/day). There was a tendency towards increased faecal elimination of lead and cadmium following the change to the vegetarian diet, but the differences were not statistically significant.
对16名从混合饮食转变为乳类素食饮食的受试者粪便中铅和镉的排泄情况进行了研究。改为素食饮食后,粪便重量显著增加,部分原因是水分含量增加。在混合饮食期间(铅排泄量范围为14至118,中位数为31微克/天;镉排泄量范围为4.5至21,中位数为12微克/天)和素食饮食期间(铅排泄量范围为19至136,中位数为42微克/天;镉排泄量范围为6.1至24,中位数为14微克/天),粪便中铅和镉的排泄存在较大的个体差异。改为素食饮食后,粪便中铅和镉的排泄有增加的趋势,但差异无统计学意义。
