“…The values of the present study are in agreement with those reported by Salthammer et al [19]. These authors recorded VOC mean values from 0.18 mg·m −3 to 1.09 mg·m −3 regarding the burning emissions of different types of wood.…”

“…In 32% (24 min) and 24% (22 min) of the combustion period for pinewood and briquettes, respectively, the limit value exceeded in at least one of the experiments. The CO mean values of this study are in agreement with the results reported by Salthammer et al [19] who observed a half-hour mean indoor concentration of 5.11 mg·m −3 when operating an open fireplace. However, the results documented by the same researchers for closed fireplaces were always below 3.24 mg·m −3 while higher CO mean levels (4.71 ± 1.89 mg·m −3 and 4.43 ± 2.17 mg·m −3 for briquettes and pinewood, respectively) were registered in the present study.…”

“…Due to the hot weather outside, the temperature values were above the established range for the occupant's comfort (23 °C to 26 °C for the summer period). Nevertheless, the magnitude of the increase of temperature or decrease of relative humidity was within the values reported by Salthammer et al [19] who evaluated the impact of operating woodburning fireplace ovens on IAQ. …”

“…These indoor sources may be associated with specific frequent activities carried out by dwellers, such as cooking [15,16], cleaning [17], candle burning [18], home heating [19][20][21][22], vacuuming [15], and other activities, which increase pollutants above acceptable indoor levels. A wide range of pollutants can originate via these activities including particulate matter (PM 2.5 , PM 10 ) [23], ultrafine particles (UFP) [15,24], volatile organic compounds (VOCs) [25,26], carbon dioxide [19], carbon monoxide [19,22], formaldehyde [19], polycyclic aromatic hydrocarbons [16,27], among others. For instance, cooking was found to increase PM levels by four times the background levels in a study at 14 naturally ventilated homes of Hong Kong [28].…”

Impact of Biomass Home Heating, Cooking Styles, and Bread Toasting on the Indoor Air Quality at Portuguese Dwellings: A Case Study

et al. 2018

This study evaluated the emissions of specific indoor sources usually present in Portuguese dwellings in order to understand their impact on the indoor air quality. With this aim, three typical activities were studied including home heating using two types of fireplaces (open and closed) and biofuels (pinewood and briquettes), cooking styles (frying and boiling) in different types of kitchen appliances, and several levels of bread toasting. The levels of specific pollutants were found to be above the established Portuguese limit values including VOCs, formaldehyde, and particulate matter (PM 2.5 and PM 10 ). Although these emissions are transient and short in duration, the resulting concentrations are high and can severely impact the occupants' daily exposure. Besides promoting good ventilation, the choice of residential appliances with low emissions should be taken into account. In addition, it is important that occupants perform specific activities following the best practices so that their exposure to pollutants is minimized.

Neapolitan pizza is traditionally cooked in wood-fired ovens ensuring high quality in cooking pizza and providing an excellence in Italian cooking tradition. Besides safeguarding Italian cooking tradition, in recent years there is a growing attention on wood-fired oven impacts both on indoor and outdoor air quality and pollution. Thus, optimal design of electric ovens alternative to wood-fired ones is an interesting concern in order to achieve both high quality of Neapolitan pizza cooking and air pollution prevention. This paper deals with a numerical investigation on thermal conditions provided by an innovative electric oven for Neapolitan pizzas cooking. A three-dimensional numerical model has been developed based on a finite volume scheme to simulate steady and unsteady operating conditions. Radiation effects of inner walls have been considered and the boundary effects of the oven, both radiative and convective, have been carefully modelled.Results have been examined in terms of heat flux distributions, temperature and velocity fields, showing good cooking conditions for pizzas.

Surgical Smoke Exposure in Operating Room Personnel

2019

View full text Add to dashboard Cite

t is widely accepted that inhalation of smoke, specifically, the particulate matter (PM) found within smoke, can cause adverse effects on health. When diathermy devices, such as electrocauterization instruments, lasers, and ultrasonic scalpels, are used during surgery, surgical smoke, also called cautery smoke, surgical plume, laser plume, and diathermy plume, is released into the ambient environment. This process occurs in open surgery as well as laparoscopic surgery, as ports are often vented into the atmosphere. There is a lack of studies regarding the long-term effects of surgical smoke; findings from such studies may inform methods to prevent adverse outcomes on the health of operating room personnel. There are several other forms of smoke that the general population encounters, including secondhand smoke, cooking smoke, and environmental pollution. There have been more in-depth studies on these forms of smoke than of surgical smoke, and they can help bolster the present knowledge of the danger of surgical smoke.Although smoke evacuation devices exist, they are not often used in practice owing to inconvenience and lack of awareness. A study done in 2016 reported that 14% of operating room personnel always used local exhaust ventilation during electrosurgery. 1 These respon-dents were also more likely to report training and employer standard procedures regarding the hazards of surgical smoke. The largest difference in consistent use of local exhaust ventilation was attributed to knowledge and training on the hazards of surgical smoke. 1 Most operating room staff acknowledge adverse symptoms (eg, coughing, headache) from surgical smoke, yet few wear effective personal protection. 2 Although multiple health organizations, such as the Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health, have created guidelines regarding exposure to surgical smoke, no laws mandate that protective measures be taken. 3,4 However, there has been increasing research and awareness of the harmful effects of surgical smoke on operating room personnel, leading to a push to increase regulation of surgical smoke exposure, for example, in the California legislature. 5 Signs regarding the dangers of surgical smoke can be found outside the operating room. 6 The medical community is becoming more sensitive to the possible hazards of surgical smoke exposure. 7 While emphasizing the importance of using current evacuation techniques is important, there are new modalities that could improve smoke evacuation beyond the simple vacuum and filter system. IMPORTANCE Smoke generated during surgical procedures has long been thought to be hazardous to hospital personnel; however, the degree of danger has yet to be determined.OBSERVATIONS The dangers of surgical smoke are associated with the composition of the plume. Small-particulate matter is found in the smoke that is easily inhaled. Particulates deposit in the lungs, circulatory system, and other organs, which may cause numerous health problems....
