背景:这项研究确定了尼日利亚阿多-埃基蒂(Ado-Ekiti)埃基蒂州立大学农业农场的牛奶中持久性有机氯农药(OCPs)残留的存在和浓度。 为了监视消费者对这些化学杀虫剂的暴露,对该研究进行了调查。 方法:采用气相色谱法和电子捕获检测器(GC-ECD)进行硅胶纯化后,对提取的农药进行定性鉴定和定量评估。 结果:结果显示,牛奶样品中存在11种OCP残留物,浓度范围为0.001-0.189 mg / l,而未检测到α-BHC,异狄氏剂,异狄氏剂醛,硫丹II,硫丹硫酸盐和甲氧基氯。 方差分析表明,除狄氏剂外,所有分析农药的水平均无明显变化。 结论:危险指数(HIs)显着低于1,范围为0.00063-0.107,表明没有潜在的健康风险。

Abstract
Background:
The study determined the presence and concentration of per-
sistent organochlorine
pesticides (OCPs) residues in cow milk from Ekiti
State University Agricultural farm in Ado-Ekiti, Nigeria. The study was in-
vestigated in order to monitor consumer’s exposure to these chemicals pesti-
cides.
Methods:
Qualitative identification
and quantification evaluation of
the extracted pesticides after clean-
up on silica gel were done with a Gas
Chromatography coupled with an Electron Capture Detector (GC-ECD).
Results:
The results revealed the presence of 11 OCPs residues in the milk
samples, with concentration range of 0.001 - 0.189 mg/l, while
α
-BHC, en-
drin, endrin aldehyde, endosulfan II, endosulfan sulphate and methoxychlor
were not detected. The analysis of varianc
e revealed no significant variation
in the levels of all the analysed pesticides except dieldrin.
Conclusion:
The
hazard indices (HIs) were significantly lower than 1 with the range of 0.00063
- 0.107, indicating no potential health risk.

1. Introduction
Livestock plays a very important role in Nigeria agriculture, contributing about
12.7% of the agricultural GDP [1]. According to National Agricultural Sample
Survey, Nigeria is endowed with an estimated cattle population of 19.5 million
[2]. The most population of these cattle is in the hands of pastoral Fulani. The
