邻苯二甲酸酯（PAEs）、双酚A（BPA）和雌激素类化合物由于其内分泌干扰作用而成为主要关注对象。然而，很少有相关的研究发生邻苯二甲酸酯，双酚A，和雌激素在食品和堆肥从不同的生长年龄的牲畜已经进行。在这项研究中，粪便，尿液和食物样品收集了一个典型的牲畜（牛）和一个特殊的牲畜（鸽子）从集中的动物饲养业务（CAFO）。单头母牛的日总雌激素排泄量为192 ~ 671 μg/d，显著高于单头鸽子的日总雌激素排泄量（0 ~ 0.01 μg/d）。结合型雌激素占粪便排泄雌激素总量的22.0-46.0%，占尿排泄雌激素总量的80.7-91.8%，表明排泄雌激素的形式取决于家畜种类和粪便类型。所有畜禽粪便和饲料中均检出BPA，鸽中含量分别为9.2- 40.2ng/g和23.1ng/g，牛中含量分别为50.5- 72.0ng/g和41.1ng/g。结果表明，食物是BPA进入奶牛和鸽子养殖过程的重要来源。在鸽子粪便样本中检测到高频率的邻苯二甲酸二乙酯（DEP），表明鸽子高度暴露于这些增塑剂。水生环境中牲畜来源的总雌二醇当量（EEQt）估计为2.99 ng/L，高于基线危害值（1 ng/L）（Xu等人，2018年）。该研究提供了关于CAFO中不同牲畜的PAEs，BPA和雌激素化合物的排放和来源的数据，并表明食物是BPA进入牲畜的重要来源。
Phthalates (PAEs), bisphenol A (BPA), and oestrogenic compounds have become major concerns due to their endocrine-disrupting effect. However, few studies related to the occurrence of PAEs, BPA, and oestrogen in food and compost from different growth age livestock have been conducted. In this study, faeces, urine and food samples were collected from a typical livestock (cow) and a special livestock (pigeon) from concentrated animal feeding operations (CAFOs). The daily total oestrogen excretion of a single cow ranged from 192 μg/day to 671 μg/day, which was significantly higher than that of a single pigeon (0–0.01 μg/day). Conjugated oestrogens represented 22.0–46.0% of the total oestrogens excreted from cow faeces and 80.7–91.8% of those from cow urine, indicating that the form of the excreted oestrogens depends on the livestock species and type of excrement. BPA was all detected in all livestock manure and food, and the concentration in pigeon was 9.2–40.2 ng/g and 23.1 ng/g respectively, while that in cattle was 50.5–72.0 ng/g and 41.1 ng/g respectively. The results indicated that the food is significant sources of BPA entering the process of cow and pigeon breeding. Diethyl phthalate (DEP) was detected at high frequency in pigeon faeces samples, suggesting that pigeons were highly exposed to these plasticisers. The total oestradiol equivalent quantity (EEQt) of livestock origin in aquatic environments was estimated to be 2.99 ng/L, which was higher than the baseline hazard value (1 ng/L) (Xu et al., 2018). The study provides data on the emissions and sources of PAEs, BPA, and oestrogenic compounds from different livestock in CAFOs and demonstrates that food is a significant source of BPA entering livestock.
