Resumen en inglés

The accumulation of plastic debris and herbicide residues has become a huge challenge and poses many potential risks to environmental health and soil quality. In the present study, we investigated the transport of glyphosate and its main metabolite, aminomethylphosphonic acid (AMPA) via earthworms in the presence of different concentrations of light density polyethylene microplastics in the litter layer during a 14-day mesocosm experiment. The results showed earthworm gallery weight was negatively affected by the combination of glyphosate and microplastics. Glyphosate and AMPA concentrated in the first centimetre of the top soil layer and the downward transport of glyphosate and AMPA was only detected in the earthworm burrows, ranging from 0.04 to 4.25 μg g−¹ for glyphosate and from 0.01 (less than limit of detection) to 0.76 μg g−¹ for AMPA. The transport rate of glyphosate (including AMPA) from the litter layer into earthworm burrows ranged from 6.6 ± 4.6% to 18.3 ± 2.4%, depending on synergetic effects of microplastics and glyphosate application. The findings imply that earthworm activities strongly influence pollutant movement into the soil, which potentially affects soil ecosystems. Further studies focused on the fate of pollutants in the microenvironment of earthworm burrows are needed.

Soil organisms, including earthworms, are a key component of terrestrial ecosystems. However, little is known about their diversity, their distribution, and the threats affecting them. We compiled a global dataset of sampled earthworm communities from 6928 sites in 57 countries as a basis for predicting patterns in earthworm diversity, abundance, and biomass. We found that local species richness and abundance typically peaked at higher latitudes, displaying patterns opposite to those observed in aboveground organisms. However, high species dissimilarity across tropical locations may cause diversity across the entirety of the tropics to be higher than elsewhere. Climate variables were found to be more important in shaping earthworm communities than soil properties or habitat cover. These findings suggest that climate change may have serious implications for earthworm communities and for the functions they provide.

Resumen en inglés

In the current study, we examine how the activities of earthworms (Lumbricus terrestris) affect microplastic (MP) distribution and concentration in soil, with a focus on low density polyethylene (LDPE). We also want to determine if MPs can be flushed out with water. We used a laboratory sandy soil column (polyvinyl chloride tube) experimental set-up and tested five different treatments: (1) treatment with just soil (control) to check if the saturated conductivity (Ksat) could be impacted by MP, (2) treatment with MP, (3) treatment with MP and litter, (4) treatment with earthworms and litter as a second control for treatment 5 and (5) treatment with MPs, earthworms and litter. Each treatment consisted of eight replicates. For the treatments with MP, the concentration of MP added at the start of the experiment was 7 % by weight (3.97 g, polyethylene, 50 % 1 mm–250 µm, 30 % 250 µm–150 µm and 20 % <150 µm) based on 52.78 g of dry litter from Populus nigra. In the treatments using earthworms, two adult earthworms, with an initial average weight of (7.14 ± 0.26) g, were placed in each column. Results showed that LDPE particles could be introduced into the soil by the earthworms.

MP particles were detected in each soil sample and within different soil layers for the earthworm treatments. Earthworms showed a tendency to transport the smaller MP particles and that the amount of MPs in size class <250 μm increased in soil samples with increasing soil depth in comparison to the other size classes. After leaching, MPs were only detected in the leachate from the treatments with the earthworms, and the MP had similar size distributions as the soil samples in the 40–50 cm layer of the treatment with MP, earthworms and litter. The results of this study clearly show that biogenic activities can mobilise MP transport from the surface into the soil and even be leached into drainage. It is highly likely that biogenic activities constitute a potential pathway for MPs to be transported into soil and groundwater.

Resumen en inglés

Agriculture intensification and the use of pesticides have led to biodiversity loss due to soil toxic compounds. Thus, soil contamination studies are important to understand the negative effects in the physicochemical interactions. The use of biomarkers through bioindicators is a useful tool for assessing toxicity in agricultural environments complemented with the determination of pesticides. The objectives of this study were to determine the presence of organochlorine (OCPs) and organophosphate (OPPs) pesticides and the soil’s potential toxicity in agricultural fields with different crops from the center of Quintana Roo State, using a set of enzymatic biomarkers (BMs), such as acetylcholinesterase (AChE), glutathione-S-Transferase (GST), and catalase (CAT) on earthworms (Eisenia fetida). Earthworms were exposed for 96 h on nine different agricultural soils as well as on a reference soil from a conservation area. Within all samples of soils, only OCPs were detected in low concentrations (ranged from non-detected to 1.40 ppm). However, no correlation was observed between these pesticides and the BMs activity. AChE and CAT activity was significantly inhibited in at least one agricultural soil if compared to the conservation area, while no significant differences of GST were observed. The AChE activity observed suggests the presence of anticholinergic substances (that were neither detected nor determined analytically) in the sampled soils. The characterization of oxidative stress BMs was not correlated with the OCPs analyzed. Our results demonstrate that further studies of toxicity under field conditions are required, given the complexity of environmental conditions outside the laboratory.

Resumen en inglés

Low-density polyethylene (LDPE) is the most abundant source of microplastic pollution worldwide. A recent study found that LDPE decay was increased and the size of the plastic was decreased after passing through the gut of the earthworm Lumbricus terrestris (Oligochaeta). Here, we investigated the involvement of earthworm gut bacteria in the microplastic decay. The bacteria isolated from the earthworm's gut were Gram-positive, belonging to phylum Actinobacteria and Firmicutes. These bacteria were used in a short-term microcosm experiment performed with gamma-sterilized soil with or without LDPE microplastics (MP). We observed that the LDPE-MP particle size was significantly reduced in the presence of bacteria. In addition, the volatile profiles of the treatments were compared and clear differences were detected. Several volatile compounds such as octadecane, eicosane, docosane and tricosane were measured only in the treatments containing both bacteria and LDPE-MP, indicating that these long-chain alkanes are byproducts of bacterial LDPE-MP decay.

Resumen en inglés

Epigeic worms modify microbial communities through their digestive processes, thereby influencing the decomposition of organic matter in vermicomposting systems. Nevertheless, the enzyme dynamics within the gut of tropically adapted earthworms is unknown, and the enzymes involved have not been simultaneously studied. The activities of 19 hydrolytic enzymes within three different sections of the intestine of Eisenia fetida were determined over a fasting period and at 24 h and 30, 60, and 90 days of vermicomposting, and data were evaluated by multivariate analyses. There were found positive correlations between the maximal activity of glycosyl hydrolases and one esterase with the anterior intestine (coincident with the reduction of hemicellulose in the substrate) and the activity of the protease α-chymotrypsin with posterior intestine. The results suggest that activities of enzymes change in a coordinated manner within each gut section, probably influenced by selective microbial enzyme enrichment and by the availability of nutrients throughout vermicomposting.

Resumen en español

La utilización de plaguicidas sintéticos para combatir las plagas influyen en la salud de diversos organismos incluyendo al hombre. Para conocer su impacto se utilizan herramientas de evaluación como especies bioindicadoras, y biomarcadores (BM) para evaluar el daño derivado de la exposición. En este sentido, diversos invertebrados del suelo (lombrices de tierra) y pequeños mamíferos silvestres pueden ser bioindicadores adecuados para este propósito debido a sus propiedades ecológicas. En la zona maya de Quintana Roo, los campos agrícolas están aledaños a zonas forestales y se utilizan paquetes tecnológicos basados en el uso de plaguicidas y fertilizantes sintéticos para el cultivo de sandía y papaya principalmente, los cuales son aplicados sin las medidas de seguridad necesarias por lo que el contacto con las especies silvestres es casi inevitable. Por lo tanto, los objetivos del presente trabajo fueron documentar la toxicidad de diferentes suelos agrícolas y su influencia en la fauna silvestre expuesta accidentalmente, tanto a escala espacial (zona de aplicación y zona conservada) y a escala temporal (lluvias-secas). Se obtuvieron muestras de suelo (análisis de presencia de plaguicidas) y se usaron lombrices de tierra, ratones y murciélagos, como bioindicadores, en los que se evaluó la toxicidad a través de biomarcadores (BM) enzimáticos como la acetilcolinesterasa (AChE), glutatión-S-Transferasa (GST) y catalasa (CAT). Se detectaron bajas concentraciones de algunos plaguicidas organoclorados tanto en el suelo como en el tejido hepático (ratones), lo que no representa un riesgo a corto plazo debido a esta condición. Asimismo, el análisis de BM mostró que la toxicidad por la exposición es moderada. También se registró una disminución en la actividad de la AChE (tanto en ratones como en murciélagos) para la temporada lluviosa, lo que sugiere una influencia de compuestos anticolinérgicos para esta temporada.

Sin embargo, a escala espacial, no se encontraron diferencias significativas en la actividad de los BM (en murciélagos), lo que sugiere que la toxicidad en este estudio se encuentra modulada por la temporalidad, más que por la distancia a la zona de aplicación de plaguicidas. Finalmente, este es el primer trabajo que documenta los efectos subletales en fauna silvestre derivados de la exposición accidental a plaguicidas en la región. Asimismo, se recomienda realizar más estudios complementando baterías de BM y comparando con sitios más alejados para tener un escenario más completo.

Resumen en inglés

Plastic residues have become a serious environmental problem in the regions with intensive use of plastic mulching. Even though plastic mulch is widely used, the effects of macro- and micro- plastic residues on the soil-plant system and the agroecosystem are largely unknown. In this study, low density polyethylene and one type of starch-based biodegradable plastic mulch film were selected and used as examples of macro- and micro- sized plastic residues. A pot experiment was performed in a climate chamber to determine what effect mixing 1% concentration of residues of these plastics with sandy soil would have on wheat growth in the presence and absence of earthworms. The results showed that macro- and micro- plastic residues affected both above-ground and below-ground parts of the wheat plant during both vegetative and reproductive growth. The type of plastic mulch films used had a strong effect on wheat growth with the biodegradable plastic mulch showing stronger negative effects as compared to polyethylene. The presence of earthworms had an overall positive effect on the wheat growth and chiefly alleviated the impairments made by plastic residues.
