Data from: Impact of cognitive tasks on CO2 and isoprene emissions from humans
<p>The human body emits a wide range of chemicals, including CO<sub>2</sub> and isoprene. To examine the impact of cognitive tasks on human emission rates of CO<sub>2</sub> and isoprene, we conducted an across subjects, counterbalanced study in a controlled chamber involving 16 adults. The chamber replicated an office environment. In groups of four, participants engaged in 30 minutes each of cognitive tasks (stressed activity) and watching nature documentaries (relaxed activity). Measured biomarkers indicated higher stress levels were achieved during the stressed activity. Per-person CO<sub>2</sub> emission rates were greater for stressed than relaxed activity (30.3 ± 2.1 vs. 27.0 ± 1.7 g/h/p, <i>p </i>= 0.0044, mean ± standard deviation). Isoprene emission rates were also elevated under stressed vs. relaxed activity (154 ± 25 µg/h/p vs. 116 ± 20 µg/h/p, <i>p</i> = 0.041). Chamber temperature was held constant at 26.2 ± 0.49 ◦C; incidental variation in temperature did not explain variance in emission rates. Isoprene emission rates increased linearly with salivary-alpha amylase levels (<i>r<sup>2</sup></i> = 0.6, <i>p</i> = 0.02). These results imply the possibility of considering cognitive tasks when determining building ventilation rates. They also present the possibility of monitoring indicators of cognitive tasks of occupants through measurement of air quality. </p>

Fig. 3 in Leaf isoprene and monoterpene emission distribution across hyperdominant tree genera in the Amazon basin
Fig. 3. Example light (dark blue trace) response curves of leaf photosynthesis (black trace), isoprene emissions (green trace) and monoterpene emissions from an individual in each of the 5 abundant genera including (a) Eschweilera sp., (b) Inga edulis, (c) Protium hebetatum, (d) Pouteria durlandii, (e) Licania oblongifolia. Also shown is an example light response curve from the monoterpene emitting species (f) Pouteria anomala. The dotted line represents a net flux of zero on the photosynthesis axis with negative values in the dark due to leaf respiration. Note that (c) Protium hebetatum is both an isoprene and monoterpene emitter while (f) Pouteria anomala is a monoterpene only emitter.
