Abstract: Background: Indoor air quality in environments where there is great circulation of people, posing risks to the health of its occupants, including allergic problems, infections and contaminations, can be aided by climatic factors, chemicals and biological agents housed in these environments, influencing the location and providing favorable conditions for the degradation of bibliographic collections. The present study investigated the presence of fungi in indoor environments in seven public and private libraries in the central region of Brazil, Mato Grosso, and verified the impact on occupational health. Results: A total of 26,194 fungal specimens were isolated from 342 dust samples collected using three techniques: Andersen’s sampler (12.3%), exposure plate dish (25.1%) and sterile swab (62.6%). A total of 184 fungal species were identified: 156 (84.8%) mycelial fungi and 28 (15.2%) yeast fungi, belonging 54 fungal genera, 43 (79.6%) mycelial fungi and 11 (20.4%) yeast fungi. The genus Aspergillus (40.6%) was one of the main fungi present in indoor air. Aspergillus niger (12.3%) was identified as the most prevalent species in literary environments, followed by Cryptococcus spp. (7.1%) and Cladosporium cladosporioides (7.0%). In relation to seasonal distribution, there was a greater fungal isolation in the dry season (54%); followed by the rainy season (46%). Conclusion: These results suggest the substrates researched in the evaluated environments presented in the form of documents, books and papers associated with dust and air humidity become suitable for microbiological proliferation. These findings highlight the importance of minimizing the risk of exposure to fungal agents, identified in pathogenic and toxigenic microenvironments in library collections.

Abstract: this work aimed to estimate genetic parameters related to the fruits production in a chilli pepper diallel (capsicum baccatum var. pendulum). five chilli pepper genitors were evaluated (uenf 1616, uenf 1624, uenf 1629, uenf 1639 and uenf 1732) and its respective hybrids f1, from a complete diallel without reciprocals. the experiment was carried out in a greenhouse covered with plastic film located in area from the consortium uenf/pesagro-rio, campos dos goytacazes, rj, from july/2009 to december/2009, in a randomized block design with three repetitions and nine plants by plot. the following agronomic traits were evaluated: canopy diameter (cd); plant height (ph); days for fruiting (df); number of fruits by plant (nfp); fruit average-weight (faw); fruit dry mass (fdm); dry matter (dm); fruit length (fl); fruit diameter (fd); fruit wall thickness (pt); total soluble solids (tss); and yield per plant (prod). only the faw, fdm and prod had absence of significance concerning the three tests of sufficiency for the additive dominant model, indicating that there is homogeneity among the variances and co-variances and, consequently, lack of epistasis in the control of character. for the faw and fdm traits, the additive genetic effects were the most important ones. nevertheless, in the prod the dominance effect was the most important. it was verified a partial dominance for faw and fdm, and an over-dominance for prod. the genitors uenf 1616 and uenf 1629 were the ones which had larger concentrations of favorable alleles for the three characteristics under study.
