MICROPLASTICS INCREASE SOIL PH AND DECREASE MICROBIAL ACTIVITIES AS A FUNCTION OF MICROPLASTIC SHAPE, POLYMER TYPE, AND EXPOSURE TIME- original data.xlsx
AI summary Read the abstract
This dataset supports a laboratory experiment testing how different microplastic shapes, polymer types, and exposure durations affect soil pH and the activity of key soil enzymes. The study found that microplastics can raise soil pH and reduce microbial enzyme activities, with effects varying depending on the type and shape of plastic.
The data is for a laboratory study in that different secondary microplastics were evaluated to test their effects on soil pH, soil respiration, and enzymatic activities (acid phosphatase, β-D-glucosidase, cellobiosidase, and N-acetyl-β-glucosaminidase). The plastics represented four microplastic shapes: fibers, films, foams, and fragments; and eight polymer types: polyamide (PA), polycarbonate (PC), polyethylene (PE), polyester (PES), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), and polyurethane (PU). The microplastics were mixed with soil (0.4 % w/w) and incubated at 25 ℃ for 31 days. Then, we collected soil samples on the 3rd, 11th, and 31st day.

Microplastics Increase Soil pH and Decrease Microbial Activities as a Function of Microplastic Shape, Polymer Type, and Exposure Time
AI summary Read the abstract
Researchers tested twelve different types of microplastics in soil and found that their effects on soil health depended heavily on the shape, plastic type, and how long they were present. Foam and fragment shapes raised soil pH the most, while polyethylene foam increased soil respiration, and several types reduced the activity of important soil enzymes. These findings help explain why microplastic studies often show conflicting results, since the specific characteristics of the plastic matter as much as its presence.

Researchers conducted a year-long soil microcosm experiment finding that polyethylene microplastics and phenanthrene, individually and combined, significantly altered soil pH, enzyme activities, and bacterial community diversity and function, with combined pollution showing the most pronounced effects.
Effects of different microplastic types on soil physicochemical properties, enzyme activities, and bacterial communities
AI summary Read the abstract
A 230-day experiment tested six types of microplastics in soil and found that each type differently altered soil moisture, chemistry, enzyme activity, and microbial communities. Biodegradable plastic (PHA) caused the most significant disruption to beneficial soil bacteria, which matters for human health because soil microbe changes can affect crop nutrition and food safety.
Inhibitory effect of microplastics on soil extracellular enzymatic activities by changing soil properties and direct adsorption: An investigation at the aggregate-fraction level
AI summary Read the abstract
Researchers studied how polyethylene microplastics affect the activity of soil enzymes over 150 days, examining responses across different soil aggregate sizes. They found that microplastics inhibited enzyme activities by altering soil properties, directly adsorbing enzymes, and competing with microorganisms for space. The study reveals that microplastic pollution can undermine key biological processes that maintain soil quality, with different soil aggregate fractions responding in distinct ways.
