概括
这项研究发现,食品污染物因季节和南佛罗里达州的社会经济地位而异. 聚合物和表面活性剂在潮湿的季节很常见,而塑化剂和药物在干燥的季节更常见.
科学领域:
- 环境化学环境化学
- 食品安全 食品安全
- 分析化学 分析化学
背景情况:
- 食物是人类污染物的关键暴露途径.
- 了解食品中的污染物概况对于公共卫生至关重要,特别是对于有幼儿家庭等弱势群体.
研究的目的:
- 调查佛罗里达州南部有小孩的家庭在食品中有机污染物的存在和分布.
- 评估食品化学成分的季节性和社会经济变化.
主要方法:
- 使用QuEChERS (快速,轻松,廉价,坚固和安全) 协议进行样品制备.
- 使用LC-Orbitrap HRMS (液态染色学-轨道高分辨率质谱) 的非目标分析 (NTA) 进行全面的污染物查.
- 使用Compound Discoverer (CD) 软件对化合物进行注释和识别,并使用盒图和主要成分分析 (PCA) 分析分布.
主要成果:
- 污染物分布中显著的季节性和社会经济差异 (p < 0.05).
- 在雨季期间观察到聚合物和表面活性物 (例如,二甲基二甲酸,N-二甲基二甲胺) 在食品中占主导地位.
- 在干旱季节发现了更高的塑化剂 (例如, bis (2-乙) 甲酸盐) 和药品 (例如,华法林) 的流行率.
- 在社会经济上层阶级的食品中发现了更高水平的1-nitrosopiperidine,而在社会经济下层阶级的食品中发现了更高水平的佐卡因.
结论:
- 季节性降水变化会影响特定污染物的运输和存在,如聚合物和表面活性剂.
- 社会经济因素与含有不同类型污染物的食物消费有关,例如尼托胺和麻醉剂.
- 该研究强调了塑造食品污染物概况的环境和社会经济因素的复杂相互作用.

Longitudinal Research
11.7K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Toxicity Testing in Animals
222
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
