“…Therefore, significant differences were observed between both methods (paired t-test, pvalue<0.01). The values using coconut charcoal sorbents were similar better to those previously reported using other solid-supports [12][13][14][15] Other problems in the sampling of malodor volatile compounds in ambient air, including RSCs, are the humidity effect and the interference caused by atmospheric oxidants [6]. .…”

“…Some light sulfur compounds, particularly mercaptans, are the main cause of bad odors both in air and in water [2]. Furthermore, some of those light sulfur compounds are also related to odor or flavor properties, not only negative [3], of foodstuffs because of their characteristic smell and low sensory thresholds.…”

“…A principal interferência observada nos trabalhos que utilizavam fibras porosas foi a saturação e competição por sítios ativos da fase devido à presença de vários COV na matriz, como mostra o trabalho de amostragem de compostos voláteis de enxofre 44 . Para uma amostragem e análise com boa exatidão, a umidade do local estudado deve ser considerada no processo de quantificação de COV, conforme discutido anteriormente na descrição do processo de absorção 23,24,29 .…”
