Abstract

Plastic waste enters the oceans and soil and is consumed by organisms and humans. Some of the ingested microplastics may remain in the human body and cause toxicity. We conducted a systematic review to estimate the extent to which humans are exposed to microplastics through consumption and performed a quality assessment of research results. We searched for studies published up to December 2023 and included studies that reported on the characteristics and estimated intake of microplastics. The quality assessment tool reported in previous studies was used for food and drinking water studies. We included 76 studies in the analysis, and the types of foods were classified into seven categories: seafood, drinking water, table salt, fruits and vegetables, beverages, condiments, and meat. The estimated daily intake of microplastics via food was 0.0002-1,531,524 MP/day, with the highest value in bottled water. The quality of food and drinking water studies was evaluated using a quantitative tool to assess reliability. The quality of food studies was 11.50 out of 20 points and the quality of drinking water studies was 11.16 out of 19 points. These results indicate that the closer the score is to the maximum, the more reliable the research findings. The quantitative assessment can be used as an indicator for evaluating the risks of microplastics and can help reduce biases that may occur during the research process. This study confirmed microplastics in foods and human exposure to up to one million microplastics daily. Our study emphasizes the potential for microplastic exposure through food intake and subsequent accumulation in the human body; therefore, efforts are needed to reduce exposure to microplastics in daily life.

对通过食物摄入的微塑料日估计摄入量进行系统综述和质量评估。
塑料垃圾进入海洋和土壤,被生物和人类食用。摄入的部分微塑料可能会残留在人体内并导致中毒。我们进行了一项系统性综述,以估算人类通过消费接触微塑料的程度,并对研究结果进行了质量评估。我们搜索了截至 2023 年 12 月发表的研究,并纳入了报告微塑料特征和估计摄入量的研究。以往研究中报告的质量评估工具被用于食品和饮用水研究。我们在分析中纳入了 76 项研究,并将食物类型分为七类:海鲜、饮用水、食盐、水果和蔬菜、饮料、调味品和肉类。据估计,每天从食物中摄入的微塑料为 0.0002-1,531,524 兆帕/天,其中瓶装水的微塑料摄入量最高。采用定量工具对食品和饮用水研究的质量进行了可靠性评估。食品研究质量为 11.50 分(满分 20 分),饮用水研究质量为 11.16 分(满分 19 分)。这些结果表明,得分越接近最高分,研究结果越可靠。定量评估可作为评价微塑料风险的指标,有助于减少研究过程中可能出现的偏差。这项研究证实,食品中含有微塑料,人类每天接触的微塑料多达一百万个。我们的研究强调了通过摄入食物接触微塑料并随后在人体内积累的可能性;因此,需要努力减少日常生活中接触微塑料的机会。

期刊介绍: Reviews on Environmental Health (REVEH) is an international peer-reviewed journal that aims to fill the need for publication of review articles on hot topics in the field of environmental health. Reviews on Environmental Health aims to be an inspiring forum for scientists, environmentalists, physicians, engineers, and students who are concerned with aspects of human health, including quality of life, that are determined by physiological and psychosociological interactions between man and physical, chemical, biological, and social factors in the environment. Reviews on Environmental Health is an important niche served by no other journal, that’s being a site where thoughtful reviews can be published on a variety of subjects related to both health and environment. One challenge is to bridge the research on environmental causes of disease with the clinical practice of medicine. Reviews on Environmental Health is a source of integrated information on environment and health subjects that will be of value to the broad scientific community, whether students, junior and senior professionals, or clinicians.
