Apú, N., Rommes, F., Alvarado-Arias, M., Méndez-Rivera, M., Lizano-Fallas, V., 2025. Endocrine-disrupting pesticide exposure relevant to reproductive health: a case study from Costa Rica. Environ Monit Assess 197, 559. https://doi.org/10.1007/s10661-025-14011-8
Abstract: Global pesticide use has increased significantly over the past decade, leading to greater exposure to contaminants and associated health risks. Endocrine-disrupting pesticides have gained attention due to their strong association with human reproductive impairments and rising global infertility rates. In Costa Rica, studies have reported reduced fertility among agricultural workers and a higher prevalence of male infertility in regions with intensive pesticide use. However, the prioritization of pesticides detected in human fluids, based on their potential impact on reproductive health, has not been conducted. Here, analyzing human biomonitoring studies in the country over the last 25 years, 13 pesticides were identified and prioritized. Mancozeb ranked highest (14.8%), followed by dieldrin (12.1%) and chlorothalonil (12.0%). Eight criteria were used for prioritization, with non-carcinogenic risk, reported reproductive effects, and endocrine disruptor classification as key factors. This comprehensive approach highlights how multiple criteria collectively inform pesticide prioritization in relation to reproductive health risks. The findings indicated that while Costa Rica is a regional leader in pesticide biomonitoring, significant gaps remain, including limited data on unstudied pesticides and general population exposures. Establishing robust biomonitoring programs and public health surveillance systems to generate updated data and support evidence-based prevention policies is recommended. Additionally, the results of this study provide a valuable framework for guiding future research on the potential effects of pesticide mixtures.
Giraldo-Sanclemente, W., Pérez-Castillo, A.G., Monge-Muñoz, M., Chinchilla-Soto, C., Chavarría-Pérez, L., Alpízar-Marín, M., Zaman, M., 2025. Impact of urease inhibitor on greenhouse gas emissions and rice yield in a rainfed transplanting rice system in Costa Rica. Frontiers in Agronomy 7. https://doi.org/10.3389/fagro.2025.1518802
Abstract: Rice crop production intensification has become one of the most important sources of greenhouse gases. In rainfed rice production, urea is the most common nitrogen (N) fertilizer used in Costa Rica. Urea has low efficiency in crops, which is associated with high risk of N gaseous losses. The use of urea coated with the urease inhibitor NBPT has been identified as a mitigation strategy for ammonia losses. However, this can increase N input to the system, potentially leading to higher N2O and CH4 emissions in rice fields. In 2022, a rainfed rice transplanting trial was conducted on a tropical Inceptisol in Costa Rican Central Pacific region to analyze yield and quantify N2O and CH4 emissions. The plots of 6m x 6m, with an experimental design of five complete randomized blocks, were treated with three N-fertilization treatments: urea (U; 144 kg N ha−1), urea plus NBPT (UI; 144 kg N ha−1) and control plots (without N). Total N was splitted in four applications. The yield did not exhibit a significant difference (p>0.05) between U and UI treatments (U: 5.72 ± 0.97 t ha−1, and UI: 5.86 ± 1.12 t ha−1). There were no significant differences in yield-scaled N2O emissions (U: 4.4 ± 1.9 ug N2O-N kg−1rice, UI: 4.2 ± 1.9 ug N2O-N kg−1rice) or yield-scaled CH4 emissions (U: 0.32 ± 0.20 mg CH4 kg−1rice, UI: 0.33 16 ± 0.18 mg CH4 kg−1rice). Environmental factors and soil conditions such as temperature, pH, clay content, and specific cation exchange capacity could reduce the efficacy of NBPT. Under the experimental conditions, NBPT did not promote economic benefits, nor did it have an impact on greenhouse gas emissions.

Rodríguez-Rodríguez, C.E., Ramírez-Morales, D., Gutiérrez-Quirós, J.A., Rodríguez-Saravia, S., Villegas-Solano, D., 2024. Occurrence of pharmaceuticals in Latin America: case study on hazard assessment and prioritization in Costa Rica. Environ Monit Assess 196, 739. https://doi.org/10.1007/s10661-024-12872-z
Abstract: Pharmaceuticals are considered as contaminants of emerging concern, and their occurrence in diverse environmental matrices has been described during the last 25 years. Nonetheless, pharmaceutical occurrence has not been evenly described worldwide, and reports from some geographical areas such as most parts of Latin America are scarce. This work aims to address the situation of water pollution due to pharmaceuticals in Latin America by means of two main goals: i. First, reviewing the monitoring studies performed in Latin America on this topic (period 2009—2024), which were conducted in Brazil, Mexico, Colombia, Ecuador, Peru and Argentina, to highlight the most frequently detected compounds from each therapeutic group in the region. ii. Second, analyzing the case of Costa Rica through the hazard assessment and prioritization of pharmaceuticals based on the monitoring performed in this country (years 2011; 2018—2019). The monitoring in Costa Rica comprised a total of 163 sampling points: wastewater treatment plants (WWTPs) (14 urban WWTPs plus two landfill WWTPs; total samples n = 44 influents and n = 34 effluents), nine hospital effluents (n = 32), wastewater from livestock farms (six swine farms and seven dairy farms; n = 23 influents and n = 37 effluents), 64 continental surface water sampling points (n = 137), and 61 coastal seawater sampling points (n = 61). Risk assessment of detected concentrations by the hazard quotient (HQ) approach (period 2018–2019) revealed a total of 25 medium or high-hazard compounds (out of 37 detected compounds). The prioritization approach (which included the Frequency of Appearance (FoA), the Frequency of PNEC exceedance (FoE), and the Extent of predicted no-effect concentration (PNEC) exceedance (EoE)), showed a critical list of nine pharmaceuticals: caffeine, diphenhydramine, acetaminophen, lovastatin, gemfibrozil, ciprofloxacin, ibuprofen, doxycycline and norfloxacin. These compounds should be taken into account as a first concern during the implementation of environmental policies related to pharmaceutical products in the region.
Pickering, L., Castro-Gutierrez, V., Holden, B., Haley, J., Jarvis, P., Campo, P., Hassard, F., 2024. How bioaugmentation for pesticide removal influences the microbial community in biologically active sand filters. Chemosphere 363, 142956. https://doi.org/10.1016/J.CHEMOSPHERE.2024.142956
Abstract: Removing pesticides from biological drinking water filters is challenging due to the difficulty in activating pesticide-degrading bacteria within the filters. Bioaugmented bacteria can alter the filter’s microbiome, affecting its performance either positively or negatively, depending on the bacteria used and their interaction with native microbes. We demonstrate that adding specific bacteria strains can effectively remove recalcitrant pesticides, like metaldehyde, yielding compliance to regulatory standards for an extended period. Our experiments revealed that the Sphingobium CMET-H strain was particularly effective, consistently reducing metaldehyde concentrations to levels within regulatory compliance, significantly outperforming Acinetobacter calcoaceticus E1. This success is attributed to the superior acclimation and distribution of the Sphingobium strain within the filter bed, facilitating more efficient interactions with and degradation of the pesticide, even when present at lower population densities compared to Acinetobacter calcoaceticus E1. Furthermore, our study demonstrates that the addition of pesticide-degrading strains significantly impacts the filter’s microbiome at various depths, despite these strains making up less than 1% of the total microbial community. The sequence in which these bacteria are introduced influences the system’s ability to degrade pesticides effectively. This research shows the potential of carefully selected and dosed bioaugmented bacteria to improve the pesticide removal capabilities of water filtration systems, while also highlighting the dynamics between bioaugmented and native microbial communities. Further investigation into optimizing bioaugmentation strategies is suggested to enhance the resilience and efficiency of drinking water treatment systems against pesticide contamination.
Genomic insights of a native bacterial consortium for wheat production sustainability
Ayala Zepeda, M., Valenzuela Ruiz, V., Parra Cota, F.I., Chinchilla-Soto, C., de la Cruz Torres, E., Ibba, M.I., Estrada Alvarado, M.I., de los Santos Villalobos, S., 2024. Genomic insights of a native bacterial consortium for wheat production sustainability. Curr Res Microb Sci 6, 100230. https://doi.org/10.1016/J.CRMICR.2024.100230
Abstract: The use of plant growth-promoting bacteria as bioinoculants is a powerful tool to increase crop yield and quality and to improve nitrogen use efficiency (NUE) from fertilizers in plants. This study aimed to bioprospecting a native bacterial consortium (Bacillus cabrialesii subsp. cabrialesii TE3T, Priestia megaterium TRQ8, and Bacillus paralicheniformis TRQ65), through bioinformatic analysis, and to quantify the impact of its inoculation on NUE (measured through 15N-isotopic techniques), grain yield, and grain quality of durum wheat variety CIRNO C2008 grown under three doses of urea (0, 120, and 240 kg N ha−1) during two consecutive agricultural cycles in the Yaqui Valley, Mexico. The inoculation of the bacterial consortium (BC) to the wheat crop, at a total N concentration of 123–225 kg N ha−1 increased crop productivity and maintained grain quality, resulting in a yield increase of 1.1 ton ha−1 (6.0 vs. 7.1 ton ha−1, 0 kg N ha−1 added, 123 kg N ha−1 in the soil) and of 2.0 ton ha−1 (5.9 vs. 7.9 ton ha−1, 120 kg N ha−1 added, 104 kg N ha−1 in the soil) compared to the uninoculated controls at the same doses of N. The genomic bioinformatic analysis of the studied strains showed a great number of biofertilization-related genes regarding N and Fe acquisition, P assimilation, CO2 fixation, Fe, P, and K solubilization, with important roles in agroecosystems, as well as genes related to the production of siderophores and stress response. A positive effect of the BC on NUE at the studied initial N content (123 and 104 kg N ha−1) was not observed. Nevertheless, increases of 14 % and 12.5 % on NUE (whole plant) were observed when 120 kg N ha−1 was applied compared to when wheat was fully fertilized (240 kg N ha−1). This work represents a link between bioinformatic approaches of a native bacterial inoculant and the quantification of its impact on durum wheat.

Abstract: Tropical peatlands are highly vulnerable to anthropogenic alterations. In Costa Rica, riverine peatlands are understudied, and most are not included in protected areas. This study aims to generating information useful to assess the anthropogenic pressure in a riverine peatland in Los Robles Sector (LRS) of Medio Queso Wetland (MQW) complex. Evaluations of impacts of fires on vegetation and surface peat chemistry, and the post-2021 fire, makeup of dominant vegetation changes with the Cyperaceae species Scleria melaleuca replacing Eleocharis interstincta as the dominant species are presented. The topsoil (0–20 cm) total C content was quantified as lower than 300 g kg−1 with no significant statistical differences in total C and N content between soil shortly after the fires or two years later. The species E. interstincta is observed to promote higher C stability during the dry season, and has a more recalcitrant composition of the root system compared to the post 2021-fire dominant S. melaleuca. To reduce the impact on C accumulation, measures to prevent grazing-originated fires, especially when the water table is low, are urgent. Hence, this work aims at proving information that can be a baseline for impacts assessment and to inform conservation measures and policies.

Bergmann, D., Matarrita-Rodríguez, J., Abdulla, H. Toward a More Comprehensive Approach for Dissolved Organic Matter Chemical Characterization Using an Orbitrap Fusion Tribrid Mass Spectrometer Coupled with Ion and Liquid Chromatography Techniques. https://doi.org/10.1021/acs.analchem.3c02599
Abstract: Dissolved organic matter (DOM) represents one of the largest active organic carbon pools in the global carbon cycle. Although extensively studied, only <10% of DOM has been chemically characterized into individual dissolved compounds due to its molecular complexity. This study introduced a more comprehensive DOM characterization method by coupling both ion chromatography (IC) and liquid chromatography (LC) with high mass accuracy and resolution mass spectrometry. We presented a new on-the-fly mass calibration of the Orbitrap technique by utilizing the “lock mass” function in the Orbitrap Fusion Tribrid mass spectrometer (OT-FTMS), which assures high mass accuracy at every scan by a postcolumn introduction of internal labeled standards. With both IC and LC, tested unlabeled standards of amino acids, small peptides, and organic acids were consistently below 1.0 ppm mass error, giving the OT-FTMS the potential of reaching mass accuracy of the Fourier-transform ion cyclotron resonance mass spectrometer. In addition to mass accuracy, a pooled quality control sample (QC) was used to increase reproducibility by applying systematic error removal using random forest (SERRF). Using an untargeted mass spectrometry approach, estuarine DOM samples were analyzed by OT-FTMS coupled to IC in negative mode and LC in positive mode detection to cover a wide range of highly cationic to highly anionic molecules. As a proof of concept, we focused on elucidating the structures of three distinct DOM compound classes with varied acidities and basicities. In UPLC-OT-FTMS, a total of 915 compounds were detected. We putatively elucidated 44 small peptides and 33 deaminated peptides of these compounds. With IC-OT-FTMS, a total of 1432 compounds were detected. We putatively elucidated 20 peptides, 268 deaminated peptides, and 188 organic acids. Except for five compounds, all putatively elucidated compounds were uniquely detected in their corresponding chromatography technique. These results highlight the need for combining these two techniques to provide a more comprehensive method for DOM characterization. Application of the combined IC and LC techniques is not limited to DOM chemical characterization. It can analyze other complex compound mixtures, such as metabolites, and anthropogenic pollutants, such as pesticides and endocrine-disrupting chemicals, in environmental and biological samples.

Pharmaceuticals, hazard and ecotoxicity in surface and wastewater in a tropical dairy production area in Latin America. Chemosphere, 346, 140443. (2024). https://doi.org/10.1016/j.chemosphere.2023.140443
Absract: Pharmaceuticals comprise a complex group of emerging pollutants. Despite the significant number of pharmaceuticals used in veterinary medicine, the input of these compounds into the environment due to livestock activities has been scarcely described. This work assays for the first time in Central America the occurrence of pharmaceuticals in farm wastewater in an area devoted to dairy production, and in the surrounding surface waters. Among 69 monitored pharmaceuticals, a total of eight compounds were detected in wastewater samples collected from seven dairy farms after three sampling campaigns. Six pharmaceuticals were considered either of high (albendazole, lovastatin and caffeine) or intermediate estimated hazard (ciprofloxacin, acetaminophen and ketoprofen) based on the HQ approach, while 26% of the samples were considered of high estimated hazard according to the cumulative ∑HQ approach. Similarly, when ecotoxicological tests were applied, all the samples showed some level of toxicity towards Daphnia magna, and most samples towards Vibrio fischeri and Lactuca sativa. Fourteen pharmaceuticals were detected in surface water samples collected in the surroundings of the dairy production farms, including rural and urban areas. Seven out of these compounds showed high estimated risk (risperidone, diphenhydramine, trimethoprim, fluoxetine, ofloxacin, caffeine and ibuprofen), while three (gemfibrozil, ciprofloxacin and cephalexin) exhibited intermediate estimated risk. In a similar worrisome way, 27% of these samples were estimated to pose high environmental risk according to the pharmaceutical content. Despite being nontoxic for D. magna or V. fischeri, frequent inhibition (>20%) of GI in L. sativa was determined in 34% of surface water samples; such findings raise concern on the apparent inceptive environmental pollution and risk within the area. According to the pharmaceutical content patterns in both kinds of studied matrices, no clear evidence of significant contamination in surface water due to livestock activities could be retrieved, suggesting a main role of urban influence.
