文章大意:本文是一篇说明文。文章介绍新的研究在新鲜的水果和蔬菜中首次检测到微塑料颗粒污染。

1 . Just when you thought you were taking care of your health by eating enough fruit and vegetables every day, new research has come out revealing that you might be swallowing microplastic particles (颗粒) along with all those vitamins, minerals, and fiber. A groundbreaking study published in the journal Environmental Research has found that fruits and vegetables absorb microplastic particles from the soil and move them through vegetal tissues, where they remain until eaten by hungry diners, thus getting transferred to human bodies.

The researchers, who are from the University of Catania in Italy, as well as Sousse and Monastir universities in Tunisia, analyzed a variety of common fruits and vegetables —carrots, lettuce, broccoli, potatoes, apples, and pears. These were chosen for the fact that they are frequently consumed, usually one per day, which allowed the researchers to better assess the dietary intakes of MPs (microplastic particles) and NPs (nano-plastics). The samples were purchased from different sources in the city of Catania, including a small fruit vendor and a supermarket.

The researchers found that apples, followed by pears, were the most polluted fruit samples, and carrots were the most polluted vegetable. In the study’s discussion section, the authors wrote, “We can assume that the fruits contain more MPs not only because of the very high vascularization (血管化) of the fruit pulp (果肉) but also due to the greater size and complexity of the root system and age of the tree (several years) compared to the vegetables (60-75 days for the carrot).”

This study is important because it's the first to detect microplastics in fruits and vegetables. They have been found in other sources before, such as sea salt, beer, water (bottled, in particular), shellfish, sugar, soil, and even air, but never inside fresh produce. It’s an alarming discovery that raises yet another red flag about microplastic pollution in the natural environment.

It’s an area that will likely see a lot more attention in coming years, with the study authors calling for further research into the question of microplastic and whether it harms the health of both plants and humans.
