ABSTRACTPneumonia is a serious health problem in the world, including in Indonesia. Based on the results of Riskesdas 2007, pneumonia was the second ranking cause of death in the proportion of children aged 1–4 years and is under the diarrhea which ranks first. Environmental factors or conditions of the house, especially the air quality in the house is said to be one of the factors that can trigger pneumonia in infants. This study was conducted to determine the correlation of indoor air quality factors with the incidence of toddler’s pneumonia. Type of this study is observational analytic and use case control design. The population of case group was all toddlers who become visitors Mojo Health Center in January 2014 until March 2014 and was diagnosed with pneumonia. While population of control group was all toddlers who become visitors Mojo Health Center in January 2014 until March 2014 and was diagnosed with diseases other than pneumonia. The number of respondents in this study were 60 respondents. The selection of the sample with simple random sampling method. The variables studied were cigarette smoke exposure in the house, size of ventilation and residential density. The results of the analysis using Epi Info StatCalc indicate that exposure to cigarette smoke in the house (OR = 4.00), size of ventilation (OR = 4.03), and residential density (OR = 4.38) has an correlation with incidence of toddler’s pneumonia. It is expected that the public can avoid air pollution in the house in order to prevent toddlers from pneumonia.Keywords: cigarette smoke, size of ventilation, residential density, air quality,                 toddler’s Pneumonia

Expiratory Flow

Subjects were exposed in a climatic chamber during 28 min to cigarette smoke produced by a smoking machine. The concentrations of CO, NO, NO2, formaldehyde and acrolein were recorded. We measured eye blinking rate, FEV1 (forced expiratory volume in one sec), MMF (maximal mid-expiratory flow), irritating effects and annoyance. Irritation (eyes and nose), annoyance and blinking rate showed an increase in relation to the number of smoked cigarettes, i.e. to the concentration of pollutants. There was a correlation between blinking rate and eye irritation in the first half of exposure. Annoyance about air quality and the wish to open the windows or to leave the room proved to be a very susceptible criterion.

The Public

While indoor air pollution is one of the leading causes of morbidity and mortality worldwide, its sources and impacts are largely misunderstood by the public. In a randomized controlled trial including 281 households in France, we test two interventions aimed at raising households' awareness of indoor pollutants and ultimately improving indoor air quality. While both generic and personalised information increase awareness, only personalised information is successful in shifting behaviour and decreasing indoor air pollution - by 20% compared to the control group. Heterogeneous treatment effects show that this effect is concentrated on the most polluted households at baseline.

Indoor Environmental Quality

In many aspects of life quality, bio-contaminants and indoor air quality have had catastrophic consequences, including a negative impact on human health with an increased prevalence of allergic respiratory reactions, asthma, and infectious diseases. We aimed to evaluate the quality of indoor air environment and find out the association between human health and indoor air pollution and also to assess the physical health status of a group of Saudi and non-Saudi populations during this pandemic. Also, we aimed to assess the most common health condition or symptoms associated with ventilation. A questionnaire was distributed online to test indoor air quality, ventilation status, common signs and symptoms of any allergy or mental status and their relationship to certain variables. A total of 362 respondents were included. Before living in the current home, flu or Influenza and chapped lips were more prevalent than allergies and chapped lips signs while living in the current home. (12.2% , 10.8% vs. 18.5% , 13.55% before and after respectively) Multiple colds were the second most common symptom (10.2%). Hoarse voice and headaches were the least common symptoms experienced; each constituted 4.4%. During the COVID-19 Pandemic, most respondents wore a facemask, approximately 76.5%; and almost one-third of respondents had bright natural light inside the current home (43.1%). The presence of natural light within the current home was significantly associated with symptoms experienced during living in the current house (p<0.05). Natural sunlight exposure could decrease allergic symptoms and minor health problems associated with poor ventilation and air quality indoors. In current living homes, the majority of respondents never used air purifiers (72.9 percent). In order to get attention from people to enhance the quality and ventilation mechanism of indoor air, special care and awareness of the effects of the use of air purifiers on human health is needed.

Reduce Emissions

&lt;p&gt;In addition to many recent actions taken to reduce emissions from energy production, industry, and transportation, a new campaign substituting residential solid fuels with electricity or natural gas has been launched in Beijing, Tianjin, and other 26 municipalities in northern China, aiming at solving severe ambient air pollution in the region. Quantitative analysis shows that the campaign can accelerate residential energy transition significantly, and if the planned target can be achieved, more than 60% of households are projected to remove solid fuels by 2021, compared with less than 20% without the campaign. Emissions of major air pollutants will be reduced substantially. With 60% substitution realized, emission of primary PM2.5 and contribution to ambient PM2.5 concentration in 2021 are projected to be 30% and 41% of those without the campaign. With 60% substitution, average indoor PM2.5 concentrations in living rooms in winter are projected to be reduced from 209 (190-230) &amp;#956;g/m3 to 125 (99-150) &amp;#956;g/m3. The population-weighted PM2.5 concentrations can be reduced from 140 &amp;#956;g/m3 in 2014 to 78 &amp;#956;g/m3 or 61 &amp;#956;g/m3 in 2021 given that 60% or 100% substitution can be accomplished. Although the original focus of the campaign was to address ambient air quality, exposure reduction comes more from improved indoor air quality because approximately 90% of daily exposure of the population is attributable to indoor air pollution. Women benefit more than men.&lt;/p&gt;

Public Health Issue

Several factors affect the indoor air quality, among which ventilation, human occupancy, cleaning products, equipment and material; they might induce the presence of aerosols (or bioaerosols in the presence of biological components) nitrogen oxides, ozone, carbon monoxide and dioxide, volatile organic compounds, radon and microorganisms. Microbiological pollution involves hundreds of bacteria and fungi species that grow indoors under specific conditions of temperature and humidity. Exposure to microbial contaminants is clinically associated with allergies, asthma, immune responses and respiratory infections, such as Legionnaires Disease and Pontiac Feaver, which are due to contamination byLegionella pneumophila. Legionnaire's Disease has increased over the past decade, because of the use of central air conditioning. In places such as homes, kindergartens, nursing homes and hospitals, indoor air pollution affects population groups that are particularly vulnerable because of their health status or age, making indoor air pollution a public health issue of high importance. Therefore, the implementation of preventive measures, as the application of air filters, is fundamental. Currently, High Efficiency Particulate Air (HEPA) filters are the most used to capture microorganisms in ventilation, filtration and air conditioning systems; nevertheless, as they are not completely secure, new filters should be developed. This work aims to present how the efficiency of a textile nanostructure in a non-woven material based on synthetic textiles (high hydrophobic fibers) incorporating appropriate biocides to controlLegionella pneumophila, is going to be measured. These bioactive structures, to be used in ventilation systems, as well as in respiratory protective equipment, will reduce the growth of microorganisms in the air through bactericidal or bacteriostatic action. The filter nanostructure should have good air permeability, since it has to guarantee minimum flows of fresh air for air exchange as well as acceptable indoor air quality.

In Delhi, one of the world's most polluted cities, there is relatively little information on indoor air pollution and how it varies by socioeconomic status (SES). Using indoor air quality monitors (IAQMs), we find that winter levels of household air pollution exceed World Health Organization standards by more than 20 times in both high-and low-SES households. We then evaluate a field experiment that randomly assigned monthlong IAQM user trials across medium-and high-SES households but suffered from significant survey non-response. Among respondents, IAQMs did not affect take-up of subsidized air purifier rentals or other defensive behavior.

Abstract: Degradation of air quality, like climate change and global warming, has become an all-encompassing existential hazard to humanity and natural life. Exposure to severely polluted air on a regular basis causes pulmonary disorders and contributes to severe allergies and asthma. According to studies, more than 10 million people die each year as a result of irregularities produced directly or indirectly by air pollution. The work of Lelieveld et al. [1] sheds light on the gravity of the problem. It is estimated that by 2050, the worldwide premature mortality from air pollution will exceed 6.6 million fatalities per year (358000 from ozone, the rest from PM 2.5) [1]. As a result, we decided to focus our study on improving indoor air quality. Despite the fact that there are numerous indoor air purifiers on the market, their cost belies their effectiveness, and the effective ones are far too expensive for working-class people to afford [2]. In order to address this issue, we created an automated Internet of Things (IoT) based air filtration system that uses an automated air purifier which is triggered when air quality falls below WHO criteria. Our initiative intends to improve indoor air quality by utilizing the most cost-effective and efficient modules available.
