Hydrogen is a ubiquitous but often neglected gas. In analytical measurements hydrogen—as harmless gas—often not considered so no studies on hydrogen in indoor air can be found. For metal oxide semiconductor (MOS) gas sensors that are increasingly pushed into the application as TVOC (total volatile organic compounds) sensors, severe disturbance. On other hand, an intentional choice indicator for...

Indoor air quality on board a 36-year-old ship has been characterized at several locations. The is dedicated to nearshore operations the Belgian coast. This paper presents time-averaged and continuous-time measurements of indoor pollutant concentrations such as NO2, O3, NO, CO, total volatile organic compounds (TVOC), polycyclic aromatic hydrocarbons (PAH), particulate matter PM2.5 PM10, black ...

Deteriorating levels of indoor air quality is a prominent environmental issue that results in long-lasting harmful effects on human health and wellbeing. A concurrent multi-parameter monitoring approach accounting for most crucial pollutants critical essential. The challenges faced by existing conventional equipment measuring multiple real-time pollutant concentrations include high cost, limite...

Background: Cooking activities generate pollutants that can cause adverse health effects to occupants. This study aims characterize the indoor air environment in small and medium food enterprises (SMEs), as studies this area are scarce. Methods: A series of field measurements were conducted investigate IAQ at 14 SMEs selected Pulau Pinang for three different cooking methods (frying, boiling, ba...

The Public Health and Safety Department of Dubai Municipality had evaluated the indoor air quality in public buildings 2013, then established IAQ (Indoor Air Quality) regulation. Even though building is control, pollution new renovated housing still very problematic. objective this paper to measure residential unit an apartment after renovation evaluate actual condition analyze influential fact...

background: many studies have been conducted to assess the indoor air quality (iaq) of buildings throughout the world because it is closely related to comfort, safety and work productivity of occupants. however, there is still lack of available literature about iaq in tropical buildings that apply radiant cooling systems in conditioning the indoor air. methods: this paper reports the results ob...

The objective of this work is to investigate the indoor environment in bedrooms ventilated by window opening during night-time. How behaviour affects air quality (IAQ), and how IAQ influenced external factors, are important questions. context renovation detached wooden houses Norway. To motivate building owners renovate their ventilation system, it know typical existing buildings with natural v...

BACKGROUND Moxibustion therapy has been used historically for thousands of years and there are many clinical trials supporting its efficacy and effectiveness for various conditions. Moxa smoke has been a major reason for avoiding moxibustion due to its smell and potential risks to the human body. METHODS 10 units of commercial indirect moxa (CIM) from six manufacturers (A-F) were burnt in a 2...

Furniture emits various VOCs (Volatile Organic Compounds) and formaldehyde (HCHO) into the indoor air. These air pollutants can cause SBS (Sick Building Syndrome), such as sickness, headache, dizziness, nausea, drowsiness, loss of concentration. This paper aims to provide essential data for improving quality by identifying characteristics emission HCHO according raw materials finishing methods ...
