Automatic Preparation and Analysis of Microplastics in Soil

User Benefits

- When soil is pretreated by sieving, the MAP-100 microplastic automatic preparation device can be used to collect microplastics from the soil. - The automatic preparation device can pretreat samples containing microplastics while also offering labor savings, improved reproducibility, and greater safety.

Introduction

Microplastics (MPs) are widely recognized as a marine environmental problem, but many reports have indicated that they are also commonly found on road shoulder and in soil and other places. If they become attached to algae, they can also sink to the seafloor. The MAP-100 microplastic automatic preparation device can automatically pretreat environmental surface waters while complying with the guidelines of the Ministry of the Environment. While the MAP-100 is designed for treating environmental surface water samples (with MP sizes from 300 µm to 1 mm), it can also be used to pretreat soil. Clearly, pretreated soil is not the same as environmental surface water, and there is a risk it may damage the tubing, switching valves, and other items in the device. This article describes pretreating soil from rice and vegetable fields with the MAP-100 and then analyzing the samples with a Fourier transform infrared spectrophotometer.
