Monitoring Indoor Air Quality for Enhanced Occupational Health
Abstract
Indoor environments are characterized by several pollutant sources. Because people spend more than 90% of their time in indoor environments, several studies have pointed out the impact of indoor air quality on the etiopathogenesis of a wide number of non-specific symptoms which characterizes the “Sick Building Syndrome”, involving the skin, the upper and lower respiratory tract, the eyes and the nervous system, as well as many building related diseases. Thus, indoor air quality (IAQ) is recognized as an important factor to be controlled for the occupantsrsquo; health and comfort. The majority of the monitoring systems presently available is very expensive and only allow to collect random samples. This work describes the system (iAQ), a low-cost indoor air quality monitoring wireless sensor network system, developed using Arduino, XBee modules and micro sensors, for storage and availability of monitoring data on a web portal in real time. Five micro sensors of environmental parameters (air temperature, humidity, carbon monoxide, carbon dioxide and luminosity) were used. Other sensors can be added for monitoring specific pollutants. The results reveal that the system can provide an effective indoor air quality assessment to prevent exposure risk. In fact, the indoor air quality may be extremely different compared to what is expected for a quality living environment. Systems like this would have benefit as public health interventions to reduce the burden of symptoms and diseases related to “sick buildings”.

Introduction
Indoor environments are characterized by several pollutant sources and health problems related to poor indoor air quality have reached increasing importance in the last years [1]. Besides, the concentration of indoor air pollutants seems to be 2–5 times higher than the concentration of outdoor pollutants [2, 3]. Furthermore, according to the United States Environmental Protection Agency [3], human exposure to indoor air pollutants may occasionally be more than 100 times higher than outdoor pollutant levels, because a homersquo;s interior accumulates and concentrates pollutants given off by finishes, furnishings and the daily activities of the occupants [4]. Actually, indoor air pollutants have been ranked among the top five environmental risks to public health. Thus, indoor air quality (IAQ) is recognized as an important matter to be addressed for the occupantsrsquo; health and comfort. This issue is even more important if we take into consideration that, today, most people spend more than 90% of their time in artificial environments [1].
In 1983, the World Health Organization (WHO) used the term “Sick Building Syndrome” (SBS) to the clinical features that we could find in building occupants as a result of the indoor air pollution [2]. Several studies have highlighted the impact of indoor air quality in the etiopathogenesis of many non-specific symptoms and clinical findings that characterize SBS. The clinical picture of this syndrome is wide as it may involve the skin (with xerosis, pruritus), the upper and lower respiratory tract (such as, dysphonia, dry cough and asthma), the eyes (ocular pruritus) and the nervous system (for example, headache and difficulty in concentration) [5, 6].
Moreover, besides the signs and symptoms of this syndrome, there are diseases which may be associated with indoor environments, namely, Legionnairersquo;s disease, extrinsic allergic alveolitis, asthma and atopic dermatitis [5, 6]. For instance, concerning atopic dermatitis, it is a chronic and inflammatory skin disease and one of the most common allergic diseases in children. Its incidence is increasing and, although it is associated with genetic factors, there is strong evidence of a role for environmental factors, namely indoor air pollutants. This is particularly important in industrialized countries, where children spend most of their time indoors [7]. Among the air pollutants linked with the exacerbation of atopic dermatitis are the volatile organic compounds [毕业论文中英文翻译对照
