Resumo: | As dust particles in laying poultry houses can have negative effects on health and on the environment,this study aimed to measure and compare dust concentrations in egg production sheds. The experiment was carried out in three sheds: Californian shed (G1), conventional closed shed with artificial ventilation (G2) and conventional closed shed without artificial ventilation (G3), and the birds housed were in the 22nd week of housing, in Cuité, Paraíba, Brazil.The dust particles were collected by a gravimetric pump, attached to the workers' clothes, at the height of the respiratory zone, being removed at the end of the working day. Using the evaluation methodologies (total or breathable dust) according to NIOSH (1998), weighing was performed with sample concentration calculation, then the particle size was measured by microscopy according to the methodology described by Feret(Santos, 2001), with diameter of function obtained using an optical microscope, and particles classified by size (inhalable <100 μm, thoracic <25 μm and breathable <10 μm).Considering the limit of concentration x exposure time of 3.0 mg/m3, according to ACGIH (2013), the sheds had the following values: G1-0.98 mg/m3, G2-1.45 mg/m3 and G3-1.13 mg/m3. In the classification of particles by size, the highest frequencieswere 83% thoracic, 13% inhalable, and 4% breathable.With the results presented, the implementation of the Respiratory Protection Program - PPR is suggested. |

Por lo tanto, el presente estudio tuvo como objetivo medir y comparar las concentraciones de polvo en entornos de trabajo de los cobertizos de polvo. Las mediciones de polvo se realizaron durante un ciclo de producción/día en tres cobertizos: cobertizo convencional (con y sin ventilación artificial) y galpón californiano, ubicado en el nordeste de Brasil. Para las variables ambientales (temperatura, humedad, velociade de aire, carga térmica radiante e índice de bulbo húmedo) se utilizó un equipo analizador de entorno multifunción conectado al microcontrolador Arduino. El polvo fue recogido por la bomba gravimétrica, calibrada para un caudal de 1,7 min. Aire L-1 con 5% de variación permitida, acoplado a un ciclón de polvo transpirable con casete, que contiene filtro de membrana de PVC (polímero de cloruro de polivinilo) de poro de 5μm y 37 mm de diámetro previamente esterilizado. Las bombas de muestreo se acoplaron a la ropa del trabajador, siendo retiradas al final de la jornada laboral, los tamaños del polvo recogido, la medición del tamaño de partícula por microscopía fue el diámetro de Feret con el uso de microscopio óptico, con aumento óptico en 5x. Entre las variables del ambiente, la humedad y la ventilación del aire se encontraban dentro de lo que prescribe la NR-17, ergonomía, ya temperatura por encima de la deseada de 20ºC y 23ºC, sin embargo para las aves, los galpones G1 y G2 mostraron condiciones térmicas adecuadas, dentro de los límites de 21 y 28 ºC. El polvo analizado en su cantidad estuvo por encima de los límites recomendados para polvo animal de 0,23mg/m3 para polvo animal, en los tamaños y dimensiones la frecuencia más alta (42%) pecho (< 25μm) e inalerable (<100μm).As emissões de poeira de aves de postura em grande escala podem ter impactos negativos à saúde e ao meio ambiente. Desta forma, o presente estudo objetivou medir e comparar as concentrações de poeira em ambientes de trabalho de galpões de poedeira. As medições de poeira foram realizadas durante um ciclo produtivo/dia em três galpões: galpão convencional (com e sem ventilação artificial) e galpão californiano, localizados no nordeste brasileiro. Para as variáveis ambientais (temperatura, umidade, velocidade do ar, carga térmica radiante e índice de bulbo úmido) foi utilizado equipamento analisador de ambiente multi-funções conectado a microcontrolador Arduino. A poeira foi coletada por bomba gravimétrica, calibrada para uma vazão de 1,7 min. L-1 de ar com 5% de variação admitida, acopladas a ciclone de poeira respirável com cassete, contendo filtro de membrana de PVC (polímero de cloreto de polivinila) de 5µm de poro e 37 mm de diâmetro previamente esterilizado. As bombas de amostragem foram acopladas a vestimenta do trabalhador, sendo retiradas ao final do dia de trabalho, o tamanho da poeira coletada foi analisado medição do tamanho das partículas por microscopia foi o diâmetro de Feret com o uso de microscópio ótico, com aumento óptico em 5x. Dentre as variáveis do ambiente, umidade e ventilação do ar estiveram dentro do que prescreve a NR-17, ergonomia, já temperatura este acima do desejado de 20ºC e 23ºC, no entanto para as aves, os galpões G1 e G2 mostraram condições térmicas adequadas, dentro dos limites de 21 e 28 ºC. A poeira analisada, em sua quantidade mostrou-se acima dos limites recomendados para poeira animal de 0,23mg/m3 para poeira animal, nos tamanhos e dimensões a maior frequência (42%) à poeira torácica (<25µm) e inalável (<100µm).Research, Society and Development2021-06-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1317010.33448/rsd-v10i7.13170Research, Society and Development; Vol. 10 No. 7; e35510713170Research, Society and Development; Vol. 10 Núm. 7; e35510713170Research, Society and Development; v. 10 n. 7; e355107131702525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/13170/14881Copyright (c) 2021 Adriana Maria dos Santos; Dermeval Araújo Furtado; José Pinheiro Lopes Neto; Fabiana Terezinha Leal de Morais; Rafael Costa Silva; Daniele Ferreira de Melohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Adriana Maria dos Furtado, Dermeval Araújo Lopes Neto, José Pinheiro Morais, Fabiana Terezinha Leal de Silva, Rafael Costa Melo, Daniele Ferreira de 2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/13170Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:34:34.639277Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
