Coffee is one of the most consumed products globally, and its contamination with potentially toxic elements (PTEs) occurs throughout the production chain and production. Therefore, the current meta-analysis study aimed to estimate the concentration of essential elements (Cu and Co) and the contamination of PTEs (Ni, Cr, Pb, As, and Cd) in coffee. The recommended databases, including PubMed, Scopus, and ScienceDirect, were investigated to collect data regarding the contamination of PTEs in coffee products from 2010 to 2021. Among 644 retrieved citations in the identification step, 34 articles were included in the meta-analysis. The pooled mean concentration of essential elements in coffee products is much higher than that of toxic elements (Co (447.106 µg/kg, 95% CI: 445.695-448.518 µg/kg) > Ni (324.175 µg/kg, 95% CI: 322.072-326.278 µg/kg) > Cu (136.171 µg/kg, 95% CI: 134.840-137.503 µg/kg) > Cr (106.865 µg/kg, 95% CI: 105.309-108.421 µg/kg) > Pb (21.027 µg/kg, 95% CI: 20.824-21.231 µg/kg) > As (3.158 µg/kg, 95% CI: 3.097-3.219 µg/kg) > Cd (0.308 µg/kg; 95% CI: 0.284-0.332 µg/kg)). Results showed high differences between pooled concentrations of all PTEs in coffee products of different countries.
咖啡是全球消费最多的产品之一，其在生产链和生产过程中都可能受到潜在有毒元素（PTEs）的污染。因此，本研究旨在通过荟萃分析来估计咖啡中的必需元素（Cu 和 Co）浓度和 PTEs（Ni、Cr、Pb、As 和 Cd）的污染情况。研究调查了推荐的数据库，包括 PubMed、Scopus 和 ScienceDirect，以收集 2010 年至 2021 年期间咖啡产品中 PTE 污染的数据。在识别阶段检索到的 644 篇引文，有 34 篇文章被纳入荟萃分析。咖啡产品中必需元素的平均浓度远高于有毒元素（Co（447.106 µg/kg，95%CI：445.695-448.518 µg/kg）> Ni（324.175 µg/kg，95%CI：322.072-326.278 µg/kg）> Cu（136.171 µg/kg，95%CI：134.840-137.503 µg/kg）> Cr（106.865 µg/kg，95%CI：105.309-108.421 µg/kg）> Pb（21.027 µg/kg，95%CI：20.824-21.231 µg/kg）> As（3.158 µg/kg，95%CI：3.097-3.219 µg/kg）> Cd（0.308 µg/kg；95%CI：0.284-0.332 µg/kg））。结果表明，不同国家咖啡产品中所有 PTE pooled 浓度之间存在很大差异。
