Manganese (Mn), an essential nutrient, is a neurotoxicant at high concentrations. We measured Mn concentrations in repeated blood and hair samples collected from 449 pregnant women living near banana plantations with extensive aerial spraying of Mncontaining fungicide mancozeb in Costa Rica, and examined environmental and lifestyle factors associated with these biomarkers. Mean blood Mn and geometric mean hair Mn concentrations were 24.4 μg/L (8.9−56.3) and 1.8 μg/g (0.05−53.3), respectively. Blood Mn concentrations were positively associated with gestational age at sampling (β = 0.2; 95% CI: 0.1 to 0.2), number of household members (β = 0.4; 95% CI: 0.1 to 0.6), and living in a house made of permeable and difficult-to-clean materials (β = 2.6; 95% CI: 1.3 to 4.0); and inversely related to smoking (β = −3.1; 95% CI: −5.8 to −0.3). Hair Mn concentrations were inversely associated with gestational age at sampling (% change = 0.8; 95% CI: −1.6 to 0.0); and positively associated with living within 50 m of a plantation (% change = 42.1; 95% CI: 14.2 to 76.9) and Mn concentrations in drinking water (% change = 17.5; 95% CI: 12.2 to 22.8). Our findings suggest that pregnant women living near banana plantations aerially sprayed with mancozeb may be environmentally exposed to Mn. El manganeso (Mn), un nutriente esencial, es un neurotóxico en altas concentraciones. Medimos las concentraciones de Mn en muestras repetidas de sangre y cabello recogidas de 449 mujeres embarazadas que vivían cerca de plantaciones de plátanos con una amplia fumigación aérea de Mn que contenía el fungicida mancozeb en Costa Rica, y examinó factores ambientales y de estilo de vida asociados a estos biomarcadores. La media de las concentraciones de Mn en sangre y la media geométrica de Mn en pelo fueron 24,4 μg/L (8,9-56,3) y 1,8 μg/g (0,05-53,3), respectivamente. Sangre Las concentraciones de Mn se asociaron positivamente con la edad gestacional a muestreo (β = 0,2; IC 95%: 0,1 a 0,2), número de miembros del hogar (β = 0.4; 95% CI: 0.1 a 0.6), y viviendo en una casa hecha de permeable y materiales difíciles de limpiar (β = 2.6; 95% CI: 1.3 a 4.0); y inversamente relacionado con el tabaquismo (β = -3.1; 95% CI: -5.8 a -0.3). Cabello Las concentraciones de Mn estaban inversamente asociadas con la edad gestacional a de muestreo (cambio porcentual = 0,8; IC del 95%: -1,6 a 0,0); y se asocian positivamente con vivir a menos de 50 m de una plantación (cambio porcentual = 42,1; IC del 95%: 14,2 a 76,9) y las concentraciones de Mn en el agua potable (cambio porcentual = 17,5; IC del 95%: 12,2 a 22,8). Nuestros hallazgos sugieren que las mujeres embarazadas que viven cerca de las plantaciones de plátanos rociadas desde el aire con mancozeb pueden estar expuestas a Mn.
