概括

在摩洛哥销售的大多数皮肤美白产品中检测到,超过了安全限值. 这突显了公共卫生风险和对危险化品成分的更严格监管的需要.

科学领域:

环境科学环境科学
公共卫生公共卫生
分析化学分析化学

背景情况:

是一种高度有毒的元素,对健康构成重大风险.
含有的皮肤美白产品在亚洲,非洲和中东的市场上普遍存在.
这些产品的使用是全球公共卫生问题,因为它们的广泛分布.

研究的目的:

为了评估摩洛哥可用的皮肤美白产品中的度.
在这个问题上在摩洛哥进行首次此类研究.
使用MA-3000直接分析仪评估含量.

主要方法:

从摩洛哥市场收集了29个皮肤美白产品样本.
使用MA-3000直接分析仪 (USEPA方法7473) 测量含量.
确保方法可靠性,检测极限 (LOD) 为0.002μg/g,量化极限 (LOQ) 为0.008μg/g.

主要成果:

Voltammetric Techniques: Linear-Scan (E vs Time)

Polarography is a classical voltammetric technique used to analyze electrochemical reactions. This method applies a linear potential sweep to a dropping mercury electrode (DME), and the resulting current is measured. A dropping mercury electrode is commonly used as the working electrode in polarography. It consists of a capillary tube filled with mercury, where the tiny droplet forms at the tip. This droplet continuously drops from the capillary, creating a new electrode surface for each...
