摘要
采集羊乳及食用饲草、饲料、青贮进行高氯酸盐污染水平测定,对羊食用饲草中高氯酸盐和羊乳中高氯酸盐的关系进行探讨,并对不同品种的乳制品进行测定,确定乳制品中高氯酸盐的污染来源。共检测羊食用饲草饲料及乳头样样本计371份,不同类别乳制品样本153份,采用高效液相色谱-串联质谱法对样品进行检测,并对数据进行统计分析。结果显示,羊食用物的高氯酸盐检出率均高于80%,饲草中高氯酸盐含量最高,不同品种的饲草中高氯酸盐含量不同,用CORREL函数相关性分析饲草和羊乳中高氯酸盐的相关系数为0.51,塔姆黑尼进行单因素方差分析表明不同种类乳制品间存在显著差异。饲草和羊乳中高氯酸盐呈中强度正相关,饲草可能是羊乳中高氯酸盐的主要来源,高积累型饲草有油菜壳、花生蔓、爬地龙和苜蓿,不同种类乳制品间存在显著差异。
Collect the levels of perchlorate pollution in milk,forage,feed,and silage of dairy goats,further explore the relationship between perchlorate in sheep feed and perchlorate in sheep milk,and determine the source of perchlorate pollution in dairy products by measuring different varieties of dairy products.A total of 371 sheep forage and teat samples were tested,and 153 dairy products were tested by HPLC/MS tandem mass spectrometry and the data were statistically analyzed.The perchlorate content in forage was the highest,and the perchlorate content in different varieties of forage was different.CORREL function correlation analysis showed that the correlation coefficient of perchlorate in forage and goat milk was 0.51.The single factor ANOVA of Tamhani showed that there were significant differences among different types of dairy products.There is a positive correlation between forage and medium strength of perchlorate in goat milk.Forage may be the main source of perchlorate in goat milk.The forage with high accumulation included rape shell,peanut vine,creeper and alfalfa.There are significant differences among different types of dairy products.
