- 评估与多草药中PAH暴露相关的潜在公共卫生风险.
- 根据已建立的毒理学指南,评估药物的安全性.
主要方法:
- 通过气相色谱 (Agilent-6890N,美国) 使用EPA-16 PAHs指南识别和量化了多环芳香碳化合物 (PAH).
- 成人和儿童的饮食摄入量估计是根据测量的PAH度计算的.
- 健康风险评估涉及确定本佐[α]烯等价物 (B[α]Peq),估计每日摄入本佐[α]烯等价物 (EDB[α]Peq) 和增量终身癌症风险.
主要成果:
- 检测到的PAH包括乙二甲 (2.74 × 10−2 ppm),二烯 (2.7598 × 10−2 ppm) 和二烯 (5.1277 × 10−2 ppm).
- 估计的烯,乙甲烯和烯的饮食摄入量在成年人中为2.466-4.615 × 10−3 ppm/mg/kg,在儿童中为1.215-2.308 × 10−3 ppm/mg/kg.
- 计算的B[α]Peq和EDB[α]Peq分别为5.6777 × 10−4和5.109912 × 10−5,其增量终身癌症风险为5.3289 × 10−12.
结论:
- 该研究表明,长期暴露于Iguedo Goko 清洁剂®的非致癌性不良健康影响的风险很大,特别是在青少年和成年人中.
- 由于检测到的PAH水平,建议谨慎使用并可能避免慢性使用.
- 在市场分销之前对草药的安全性评估进行政策制定和执法至关重要.

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Hazard Ratio
115
The hazard ratio (HR) is a widely used measure in clinical trials to compare the risk of events, such as death or disease recurrence, between two groups over time. It reflects the ratio of hazard rates—the instantaneous risk of the event occurring—between a treatment group and a control group. This measure provides valuable insights into the relative effectiveness of a treatment by assessing how the risk of an event differs between the two groups.

Pharmacovigilance
826
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
