Data accompanying the paper "Tracking the source of microplastics in soil—an exploratory case study in peach orchards from east‑central Portugal"
AI summary Read the abstract
Researchers investigated the presence and potential sources of microplastics in agricultural soils, irrigation water, sheep manure, and atmospheric deposition across 19 peach orchards in the Beira Interior region of Portugal, providing a multi-matrix dataset to trace microplastic contamination pathways in a Mediterranean agricultural context.
This study investigaties the presence and potential sources of microplastics (MP) in agricultural soils under typical conditions of the Mediterranean region, characterised by dry summers and relatively moist and mild winters. Microplastic contents were analysed in the following matrices: soil samples (0-5 cm, 5-15 cm and 15-25 cm), water samples (drippers, and water deposit), sheep manure samples and atmosferic deposition samples. Collected at 19 different orchards in Castelo Branco, Fundão, Covilhã, and Belmonte; Beira Interior region, Portugal.

Tracking the source of microplastics in soil—an exploratory case study in peach orchards from east-central Portugal
AI summary Read the abstract
Researchers tracked the sources and types of microplastics found in agricultural soil at peach orchards in east-central Portugal by analyzing soil, irrigation water, organic fertilizers, and atmospheric fallout. They identified microplastics from multiple entry points, including irrigation and soil amendments, with fibers and fragments being the most common shapes. The study demonstrates the need for a multi-source approach to understanding how microplastics accumulate in farmland.

Assessing microplastic pollution in horticultural soils under greenhouse cultivation in northern Portugal
AI summary Read the abstract
Researchers characterized and quantified microplastic pollution in greenhouse horticultural soils in the Minho region of northern Portugal, sampling multiple greenhouses with varying crop types, plastic cover durations, and agricultural practices using stratified random sampling. The study assessed microplastic presence, distribution, and characteristics across sites to evaluate the environmental implications of intensive plastic use in greenhouse agriculture.
