In this study, microplastic contamination in water, natural mineral water and mineral water, sparkling soft drinks, cold tea and some traditional beverages marketed in Türkiye were assessed. Microplastics physically and chemically characterized by microscope and ATR/FT-IR, respectively. Microplastics were detected in 9 out of 47 beverage samples. A total of 250 microplastics with 5 different polymers, 2 different shapes, and 7 different colours were detected in 47 beverage samples. The average microplastic concentration was 2.24 ± 9.86 particles/L for all beverages analysed. The highest average microplastic concentration was found in mineral waters in glass bottles (average 11.3 particles/L). No microplastics were found in cold tea and other drinks. The total annual microplastic exposure from beverage consumption in male and female individuals aged >15 years was 2029 and 1786 particles/mL/year, respectively. The microplastic load index category of all beverage samples was determined as "moderate". The average pRi level of all beverages was 117 ± 260 and the risk level was determined as "low". The study provides evidence that microplastics are common in beverages and that microplastics are directly ingested by humans.
本研究评估了土耳其市场上销售的水、天然矿泉水和矿泉水、碳酸软饮料、凉茶和一些传统饮料中的微塑料污染情况。通过显微镜和 ATR/FT-IR 分别对微塑料进行了物理和化学特性分析。在 47 个饮料样品中检测到 9 个样品中存在微塑料。在 47 个饮料样品中共检测到 250 个微塑料，它们由 5 种不同的聚合物、2 种不同的形状和 7 种不同的颜色组成。所有分析饮料的平均微塑料浓度为 2.24±9.86 个/升。在玻璃瓶中的矿泉水的平均微塑料浓度最高（平均 11.3 个/升）。在凉茶和其他饮料中未发现微塑料。在 >15 岁的男性和女性个体中，每年因饮用饮料而摄入的微塑料总量分别为 2029 个和 1786 个/毫升/年。所有饮料样品的微塑料负荷指数类别均为“中度”。所有饮料的平均 pRi 水平为 117±260，风险水平被确定为“低”。该研究提供了证据表明微塑料在饮料中很常见，并且微塑料会被人类直接摄入。
