Análisis geoespacial de zonas de amortiguamiento por fumigación aérea de plaguicidas en el cultivo de banano, Costa Rica
La aplicación aérea de plaguicidas está permitida en América Latina y Estados Unidos, pero prohibida en la Unión Europea. En Costa Rica, se establece una franja de ≥100 metros sin aplicación aérea, reducible a 30 metros si existe una barrera natural. El objetivo del estudio fue analizar zonas de amortiguamiento y algunas prácticas de aviación agrícola en fincas bananeras del cantón de Matina, Costa Rica, según la reglamentación existente. Durante el I semestre 2021, se utilizó imágenes satelitales de Google Earth para la fotointerpretación e identificación de barreras naturales del área del estudio. Posteriormente, se visitaron 63 sitios sin barrera natural y se entrevistó a 58 personas vecinas sobre prácticas de fumigación. Se analizó la información recolectada en ArcGIS 10.7. l adyacentes a viviendas y carreteras. Durante el último mes, el 88% de las personas entrevistadas reportó aplicaciones aéreas a <100 metros de espacios públicos en sitios sin, o a <30 metros de espacios públicos en sitios con, una barrera natural. Además, 43% indicó haber observado trabajadores dentro del campo de cultivo durante aplicaciones por vía aérea, y 59% en condiciones ventosas. Se estimó un 3,3 km2 de cultivos de banano sembrados en áreas de protección. Los resultados sugieren que las empresas bananeras del cantón de Matina frecuentemente incumplen la regulación costarricense de aviación agrícola. Los sistemas de información geográfica forman una valiosa herramienta para fortalecer la implementación de legislaciones ambientales en América Latina.

Kidney Function in Rice Workers Exposed to Heat and Dehydration in Costa Rica
The aim of this study was to evaluate heat exposure, dehydration, and kidney function in rice workers over the course of three months, in Guanacaste, Costa Rica. We collected biological and questionnaire data across a three-month-period in male field (n = 27) and other (n = 45) workers from a rice company where chronic kidney disease of unknown origin (CKDu) is endemic. We used stepwise forward regression to determine variables associated with estimated glomerular filtration rate eGFR at enrollment and/or change in eGFR, and Poisson regression to assess associations with incident kidney injury (IKI) over the course of three months. Participants were 20–62 years old (median = 40 in both groups). Dehydration was common (≥37%) in both groups, particularly among other workers at enrollment, but field workers were more exposed to heat and had higher workloads. Low eGFR (2) was more prevalent in field workers at enrollment (19% vs. 4%) and follow-up (26% vs. 7%). Field workers experienced incident kidney injury (IKI) more frequently than other workers: 26% versus 2%, respectively. Age (β = −0.71, 95%CI: −1.1, −0.4), current position as a field worker (β = −2.75, 95%CI: −6.49, 0.99) and past work in construction (β = 3.8, 95%CI: −0.1, 7.6) were included in the multivariate regression model to explain eGFR at enrollment. The multivariate regression model for decreased in eGFR over three month included current field worker (β = −3.9, 95%CI: −8.2, 0.4), current smoking (β= −6.2, 95%CI: −13.7–1.3), dehydration (USG ≥ 1.025) at both visits (β= −3.19, 95%CI: −7.6, 1.2) and pain medication at follow-up (β= −3.2, 95%CI: −8.2, 1.95). Current fieldwork [IR (incidence rate) = 2.2, 95%CI 1.1, 5.8) and being diabetic (IR = 1.8, 95%CI 0.9, 3.6) were associated with IKI. Low eGFR was common in field workers from a rice company in Guanacaste, and being a field worker was a risk factor for IKI, consistent with the hypothesis that occupational heat exposure is a critical risk factor for CKDu in Mesoamerica.
