Measurement of Air Pollution Parameters in Montenegro Using the Ecomar System

Abstract

Particulate matter air pollution is one of the most dangerous pollutants nowadays and an indirect cause of numerous diseases. A number of these consequences could possibly be avoided if the right information about air pollution were available at a large number of locations, especially in urban areas. Unfortunately, this is not the case today. In the whole of Europe, there are just approximately 3000 automated measuring stations for PM10, and only about 1400 stations equipped for PM2.5 measurement. In order to improve this issue and provide availability of real-time data about air pollution, different low-cost sensor-based solutions are being considered both on-field and in laboratory research. In this paper, we will present the results of PM particle monitoring using a self-developed Ecomar system. Measurements are performed in two cities in Montenegro, at seven different locations during several periods. In total, three Ecomar systems were used during 1107 days of on-field measurements. Measurements performed at two locations near official automated measuring stations during 610 days justified that the Ecomar system performance is satisfying in terms of reliability and measurement precision (NRMSE 0.33 for PM10 and 0.44 for PM2.5) and very high in terms of data validity and operating stability (Ecomar 94.13%–AMS 95.63%). Additionally, five distant urban/rural locations with different traffic, green areas, and nearby industrial objects were utilized to highlight the need for more dense spatial distributions of measuring locations. To our knowledge, this is the most extensive study of low-cost sensor-based air quality measurement systems in terms of the duration of the on-field tests in the Balkan region.

Exploring the Potential of Big Data Analytics in Urban Epidemiology Control: A Comprehensive Study Using CiteSpace

“…Big data can be used to identify sources of pollution, track changes over time, and understand the health impacts of air pollution. This can help inform policies and interventions to reduce exposure and improve public health [83][84][85]. x.…”

Modeling and implementation of a low-cost IoT-smart weather monitoring station and air quality assessment based on fuzzy inference model and MQTT protocol

“…However, due to financial constraints, many economically developing countries are unable to invest in professional stations that enable air pollution monitoring and forecasting. Thus, their geographical distribution is very limited, mostly due to the high equipment price and the difficulty and cost of maintenance (Zaric et al 2021 ), which leads to limited available climate information. For instance, the national network for monitoring air quality in Morocco consists only of 29 fixed stations to measure, forecast, and notify the public, local authorities, and decision-makers on air quality.…”

“…The affordability of low-cost air sensors can enable air quality assessment in regions where air quality data has never been available previously. Numerous models for the evaluation and surveillance of air pollutants have been proposed in the literature (Megantoro et al 2021;Messan et al 2022;Sung and Hsiao 2021;Zaric et al 2021). However, their inability to address the ambiguity and inconsistency prevalent in this complicated environmental challenge is their most significant flaw.…”

Differentiating Semi-Volatile and Solid Particle Events Using Low-Cost Lung-Deposited Surface Area and Black Carbon Sensors

“…Additionally, advancements from this work allows for greater insight into PM composition and size. It adds to the repertoire of low-cost particle sensor uses and gives a new application for the CS that has previously been used for tailpipe studies, elucidating on direct particle emissions, rather than ambient aerosols [23,24]. With the plethora of low-cost BC and LDSA data that has been and will be collected due to the enhanced accessibility of handheld devices, the work presents an additional assessment mechanism to understand the characteristics of the measured particles, replacing costly instrumentation.…”
