Resumo: | In environments with photocopiers, among the monitored contaminants, there are the volatile organic compounds (VOCs), aromatic polycyclic hydrocarbons, aldehydes, ketones, ozone, and particles. The present study aimed at the assessment of the genotoxicity of the air in environments with photocopiers. Six clones of Tradescantia (4430) had been kept for 15 days in two environments – one of them with four photocopiers working 12 hours per day, and the other with three photocopiers working 8 hours per day. Other six plants comprised the check group and were kept in greenhouse. The frequency of genic and chromosomal mutations was determined through the assessment of the stamen hair cells, and tetrads, respectively, performed 15 days after the exposition. There were quantified 415 stamen hairs and 1,500 tetrads per treatment. The plants from treatment 1 – exposed to daily cycles of 12 hours with 4 photocopiers – have presented the highest frequency of chromosomal damage with significant differences in relation to the check group (p< 0.01). No significant difference was observed in the stamen hairs for genic mutation in relation to the check group. |

O presente estudo teve como objetivo avaliar a genotoxicidade do ar em ambientes com fotocopiadoras. Seis clones híbridos BNL 4430 of Tradescantia (T. subcaulis Bush x T. hirsutifolia Bush) foram mantidos durante 15 dias em dois ambientes: um deles contendo quatro máquinas fotocopiadoras que funcionam durante 12 horas/dia (tratamento 1) e outro com três máquinas, que funcionam durante 8 horas/dia (tratamento 2). Outras seis plantas constituíram o grupo controle e foram mantidas em uma casa de vegetação. A frequência de mutações gênicas e cromossômicas foi determinada a partir de cinco avaliações das células do pêlo estaminal e tétrades, após 15 dias de exposição. Foram quantificados 415 pêlos estaminais e 1.500 tétrades por tratamento. As plantas do tratamento 1 apresentaram diferenças significativas em relação ao grupo controle (p≤0,05) para a frequência de danos cromossômicos. Nos pêlos estaminais não foram observadas diferenças significativas para as mutações gênicas em relação ao grupo controle.Universidade Federal do Rio Grande do Sul (UFRGS), Instituto de Biociências2020-05-01T02:35:07Z2020-05-01T02:35:07Z2009-09info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfFILIPINI, G.

Six clones of Tradescantia (4430) had been kept for 15 days in two environments – one of them with four photocopiers working 12 hours per day, and the other with three photocopiers working 8 hours per day.
