Abstract

Background:

Microplastics (MPs) have contaminated all compartments of the marine environment including biota such as seafood; ingestion from such sources is one of the two major uptake routes identified for human exposure.

Objectives:

The objectives were to conduct a systematic review and meta-analysis of the levels of MP contamination in seafood and to subsequently estimate the annual human uptake.

Methods:

MEDLINE, EMBASE, and Web of Science were searched from launch (1947, 1974, and 1900, respectively) up to October 2020 for all studies reporting MP content in seafood species. Mean, standard deviations, and ranges of MPs found were collated. Studies were appraised systematically using a bespoke risk of bias (RoB) assessment tool.

Results:

Fifty studies were included in the systematic review and 19 in the meta-analysis. Evidence was available on four phyla: mollusks, crustaceans, fish, and echinodermata. The majority of studies identified MP contamination in seafood and reported MP content $less than 1 microplastic per gram$ , with 26% of studies rated as having a high RoB, mainly due to analysis or reporting weaknesses. Mollusks collected off the coasts of Asia were the most heavily contaminated, coinciding with reported trends of MP contamination in the sea. According to the statistical summary, MP content was $0 to 10.5 microplastics per gram$ in mollusks, $0.1 to 8.6 microplastics per gram$ in crustaceans, $0 to 2.9 microplastics per gram$ in fish, and $1 microplastic per gram$ in echinodermata. Maximum annual human MP uptake was estimated to be close to 55,000 MP particles. Statistical, sample, and methodological heterogeneity was high.

Discussion:

This is the first systematic review, to our knowledge, to assess and quantify MP contamination of seafood and human uptake from its consumption, suggesting that action must be considered in order to reduce human exposure via such consumption. Further high-quality research using standardized methods is needed to cement the scientific evidence on MP contamination and human exposures. https://doi.org/10.1289/EHP7171

供人类食用的海鲜的微塑料污染：系统回顾和荟萃分析

抽象的

背景：

微塑料（MP）污染了海洋环境的所有部分，包括海鲜等生物群；从这些来源摄入是确定的人类接触的两条主要吸收途径之一。

目标：

目标是对海鲜中 MP 污染水平进行系统审查和荟萃分析，并随后估计人类每年的摄入量。

方法：

检索了 MEDLINE、EMBASE 和 Web of Science 从发布（分别为 1947 年、1974 年和 1900 年）到 2020 年 10 月的所有报告海鲜物种中 MP 含量的研究。对发现的 MP 的平均值、标准差和范围进行了整理。使用定制的偏倚风险 (RoB) 评估工具对研究进行系统评估。

结果：

系统评价纳入了 50 项研究，荟萃分析纳入了 19 项研究。有四个门的证据：软体动物、甲壳动物、鱼类和棘皮动物。大多数研究发现海鲜中存在 MP 污染并报告了 MP 含量 $less than 1 microplastic per gram$ ，26% 的研究被评为具有高 RoB，这主要是由于分析或报告存在缺陷。在亚洲海岸收集的软体动物污染最严重，这与海洋中 MP 污染的报告趋势一致。据统计，MP含量为 $0 to 10.5 microplastics per gram$ 在软体动物中， $0.1 to 8.6 microplastics per gram$ 在甲壳类动物中， $0 to 2.9 microplastics per gram$ 在鱼中，以及 $1 microplastic per gram$ 在棘皮动物中。据估计，人类每年最大 MP 吸收量接近 55,000 个 MP 颗粒。统计、样本和方法学的异质性很高。

讨论：

据我们所知，这是第一次系统评价，旨在评估和量化海鲜中的 MP 污染以及人类从其消费中吸收的情况，表明必须考虑采取行动，以减少人类通过此类消费而接触的物质。需要使用标准化方法进行进一步的高质量研究，以巩固有关 MP 污染和人体暴露的科学证据。 https://doi.org/10.1289/EHP7171
