Indoor air pollution and the contribution of biosensors

Abstract

A vast majority of people today spend more time indoors than outdoors. However, the air quality indoors may be as bad as or even worse than the air quality outside. This is due to the continuous circulation of the same air without proper ventilation and filtration systems, causing a buildup of pollutants. As such, indoor air quality monitoring should be considered more seriously. Indoor air quality (IAQ) is a measure of the air quality within and around buildings and relates to the health and comfort of building occupants. To determine the IAQ, computer modeling is done to simulate the air flow and human exposure to the pollutant. Currently, very few instruments are available to measure the indoor air pollution index. In this paper, we will review the list of techniques available for measuring IAQ, but our emphasis will be on indoor air toxicity monitoring.

Review—Recent Advances in Nanosensors for Precision Agriculture

“…10 The high sensitivity, specificity, stability and accuracy followed by the rapid response rate make nanosensors more useful for smart agriculture over conventional sensors due to their higher surface to volume ratio, and faster electron transfer kinetics. [11][12][13][14][15][16][17][18][19][20][21] With the technological revolution being made in nanotechnology, nanosensors have been developed to play a significant role in the advancement of agriculture. The application of nanosensors can revolutionize agriculture by providing rapid updates in the growing environment, such as air flow, air humidity, carbon dioxide, temperature, pH and dissolved oxygen in water.…”

A review of zeolite materials used in membranes for water purification: history, applications, challenges and future trends

“…42,43 They have been used as well in chemical sensors to measure and control industrial processes, [44][45][46] or as anticorrosion coatings, 47 in radiation measurements, 48 energy recovery technologies, 49 solar energy and thermal adsorption storage, [49][50][51][52] gas separation, air purification 53,54 and measuring indoor air quality. 55 Zeolites are also widely utilized in a range of environmental applications, including the remediation of pollution related to the disposal of hazardous materials in municipal, industrial and agricultural wastewater. 34,[56][57][58] They have also been employed in agricultural activities to modify and improve the physical properties of clay or sandy soil by increasing the waterholding and the cation exchange capacity of the soil, retaining water and nutrients in the soil which consequently leads to higher crop yields and prevents contamination of watercourses.…”

First‐Principles Investigation of Antimonene Nanoribbons for Sensing Toxic NO2 Gas

“…The developments of biomolecules and gas sensors have discovered wide applications in environmental monitoring, protection, industrial control, and indoor air quality control. [1][2][3][4] It is well known that different air toxins/pollutants released from industries, automobiles, and household appliances are responsible for global environmental issues, such as acid rain, global warming, and depletion of the ozone layer. [5,6] Today, carbon pollution gets all the attention for its role in climate change, but nitrogen pollution is an equally challenging problem.…”
