概括

在37.1%的伊朗大米样本中检测到阿弗拉托克素B1 (AFB1),其中一些超过了欧盟限制. 卫生风险评估表明公共卫生问题,特别是儿童,强调需要对大米进行AFB1监测.

科学领域:

食品安全和毒理学
毒素分析毒素分析
公共卫生风险评估公共卫生风险评估

背景情况:

毒素,特别是亚毒素 (AFs),污染了大米等主食,对人类健康和经济构成重大风险.
由于其致癌性,急性和慢性影响,通过饮食暴露于亚毒素B1 (AFB1) 是一个主要的公共卫生问题,特别是在食用大米的人群中.

研究的目的:

为了确定伊朗大米样本中AFB1的发生率和度.
通过在伊朗食用大米对AFB1暴露进行健康风险评估.

主要方法:

竞争ELISA被用于测量来自德黑兰市场的70个伊朗大米样本中的AFB1存在和度.
健康风险评估包括计算估计的每日摄入量 (EDI),暴露率 (MOE) 和肝癌风险.

主要成果:

在37.1%的样本中发现AFB1,平均度为1.86 ± 0.67 ng/g.
7个样本超过了欧盟的限制 (2 ng/g),但没有超过伊朗国家标准化组织的限制 (5 ng/g).
儿童的平均EDI为9 ng/kg bw/day,成年人为3 ng/kg bw/day,MOE值 (18为儿童,64为成年人).

结论:

伊朗大米中的AFB1污染对公众健康构成问题,特别是对儿童来说,需要监管监测.
这些发现强调了对大米中AFB1水平的监测的重要性,以确保食品安全并保护伊朗和类似地区的公共卫生.

Toxicity Testing in Animals

Toxicity Testing in Animals

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...
