Avaliação de poluentes aéreos em instalações de creche e terminação de suínos

Abstract: RESUMO Esta pesquisa foi desenvolvida em duas instalações para suínos nas fases de creche e terminação, em duas salas cada, em granjas localizadas no município de (0,84-9,16mg m -3 ) do que nos de terminação (0,84-3,34mg m -3

“…These low values of ammonia inside the facilities are necessary for animal welfare and, according to BARKER et al (2002), exposure to concentrations above 6 ppm leads to irritation of mucous membranes and exposures above 20 ppm causes eye irritation and respiratory problems. This concentration of NH 3 similar in the dry season (summer) and rainy (winter) is in disagreement with other work, such as SAMPAIO et al (2007b), citing higher levels of NH 3 in the winter, and this fact justifies the conditions of climate and management at this time of year, like the closing of facilities, which favors the formation of ammonia and, consequently, a higher concentration. However, PAULO et al (2008), reported that ammonia levels are higher in summer, and this increase is associated to the fact that the animals ingest a larger amount of water and the need for constant power, a scenario that also generates increased production of solid and liquid waste and, consequently, increased production of gas on the installations.…”

“…Pigs subjected to high temperatures reduce the productive and reproductive performances; reduce the strength of the immune system, leaving them susceptible to infections, respiratory illnesses and gastrointestinal diseases (MANNO et al, 2006;SAMPAIO et al, 2007b;TOLON et al, 2010).…”

“…Na composição da dose diária, o nível de pressão sonora está abaixo do nível de ação, desobrigando a exigência do uso de protetor auricular. Este estudo corrobora com Sampaio et al (2007), no qual os níveis de ruído gerados pelos animais na terminação foram, em média, de 73 dB(A), estando de acordo com os limites de tolerância estabelecido pela norma NR-15 (BRASIL, 2011). O barulho dos animais e máquinas dificulta a comunicação dentro do local, chegando a interferir na concentração e tomada de decisão.…”

“…Indiretamente, outros produtos são liberados para o ar provenientes dos dejetos, como calor, umidade, gases da digestão aeróbica e anaeróbica da cama e dejetos, e poeira liberada pelos arredores, pelo piso e pela ração. A ocorrência dos agentes ambientais nas instalações pode estar relacionada, também, a fatores como estado de limpeza, a falta de cuidados com os animais, as formas de condução das operações e a infiltração de água nas instalações, o que favorece o estabelecimento de processos como combustão ou fermentação e geração de gases tóxicos (SAMPAIO et al, 2007).…”
