Abstract: Microcystins (MCs) are toxins produced by cyanobacteria from water environments that can&#xD;
induce acute and chronic effects on humans and animals, after ingestion/contact with contaminated&#xD;
water. This group of cyclic heptapeptides comprises approximately 80 variants,&#xD;
being microcystin-LR (MCLR) the most frequent and toxic variant. The studies of MCs effects on cell lines often lead to contradictory results, given the fact that&#xD;
distinct MC toxicity endpoints (mainly cytotoxicity and genotoxicity) have been studied in&#xD;
diverse cell lines (and cell clones) under distinct exposure conditions (different doses-ranges,&#xD;
time of exposure, MCs variants, etc). In our work with Vero-E6 cells we tested MCLR (both&#xD;
pure toxin and from cyanobacterial extracts of M. aeruginosa) within a wide range of concentrations&#xD;
(1 nM- 200 μM), using several endpoints and methodologies (cytotoxicity, morphology,&#xD;
genotoxicity, protein expression). In this chapter we will summarize our results and&#xD;
discuss the utility of Vero-E6 cell line to evaluate the toxicological properties of MCLR.</summary>

Authors: Proença, Maria do Carmo; Cano, Manuela
Abstract: Uma vez que 80-90% da nossa vida é passada no interior, nas últimas décadas tem-se verificado uma crescente preocupação da comunidade científica com a Qualidade do Ar Interior (QAI), devido aos efeitos que a mesma pode exercer sobre a saúde dos seres humanos.&#xD;
Com o intuito de melhorar a eficiência energética, os edifícios actuais são mais estanques favorecendo a acumulação de contaminantes gerados no interior quando a ventilação é insuficiente. Em Portugal, na sequência da Directiva 2002/91/CE foi revista a legislação e, em 2006, foi publicado o RSECE - eficiência energética de edifícios com sistemas de AVAC e que, entre outros, estabelece requisitos para a Qualidade do Ar Interior. &#xD;
Este artigo refere os principais contaminantes do ar interior, suas principais fontes e efeitos na saúde. Descreve a metodologia de avaliação da QAI bem como os valores de referência adoptados. São descritos alguns casos de estudo, suas principais conclusões e recomendações.</summary>
