“…The ASTM D1739 reference method was used for the collection of PM concentration level data and for final calculation of PM concentration levels to determine agreement between the PM concentrations received over the sampling period [17]. Particulate monitoring was conducted over a period of three months.…”

This study aimed to estimate the prevalence of respiratory symptoms and to assess respiratory health risks associated with Particulate Matter (PM) exposure among the residents of Windhoek, Namibia. Objectives: To measure particulate pollution concentration in Windhoek through monitoring of particulate matter concentration and to identify any associations between particulate pollution, individual location, and respiratory health among the Windhoek resident’s. Methods: an adapted standardized self-administered questionnaire was used to collect respiratory health related data as well as previous exposure, while PM monitoring was done using the ASTM (American Standard Test Method) D1739 reference method. Results: A high prevalence was observed for cough (43%), breathlessness (25%), and asthma (11.2%). PM was found to be a significant risk factor for episodes of coughing and phlegm, while high PM exposure category had an increased odds ratio (OR) for episodes of phlegm and cough (OR: 2.5, 95% CI (95% confidence intervals): 0.8–8.0). No association was observed between location and respiratory health outcomes. Conclusions: The study found high levels of PM concentration across all Windhoek suburbs which were above the German, American, and Environmental Protection Agency (EPA). Enactment of legislation relating to the control and monitoring of PM related emissions at the point of generation is required at both a country and city level.

“…In Santiago, the variability range is more limited than the one found in other cities of South America. It does not show extreme values such as those found in Raipur (India), where SPM values are strongly influenced by industrial activity outside and inside the city (Gurugubelli et al, 2013), or those found in Iran due to sandstorms from the desert (Malakootian et al, 2013;Naddafi et al, 2006). The two previous studies also mention significant contributions to SPM from industrial sources and an important role of dry weather on particle resuspension.…”

“…SPM in this site also significantly correlates with meteorological variables (temperature, wind, and relative humidity). It has been suggested that surfaces without green or vegetation spaces remove fewer particles from the air (sink effect) and thus increase the SPM sedimentation rate when in conjunction with high traffic (vehicles as particle emitters and suspenders) (Alahmr et al, 2012;Naddafi et al, 2006;Norela, Norfatihah, Maimon, & Ismail, 2009), particularly during warm and dry seasons when particle suspension is facilitated (Malakootian et al, 2013;Ramsperger, Peinemann, & Stahr, 1998). fic (Alahmr et al, 2012;Norela et al, 2009).…”

“…A high sedimentation rate of SPM causes discomfort and a negative effect of the environment, especially in urban and residential areas (Machado et al, 2018). It may contain various types of particles having toxic effects for humans and ecosystems as well as important corrosive effects on monuments and sculptures (Alahmr, Othman, Abd Wahid, Halim, & Latif1, 2012;Chabas et al, 2010;Gulsona et al 1995;Malakootian, Ghiasseddin, Akbari, & Jaafarzadeh-Haghighi, 2013;Sharma, Agrawal, & MarshalL, 2008;Trujillo-gonzález, Torres-Mora, Keesstra, Brevik, & Jiménez-Ballesta, 2016). A relevant characteristic of SPM is the permanent bidirectional mass transfer dynamic between the air and the soil dust.…”

Settleable particulate matter (SPM) is an atmospheric pollutant harmful to human health and the environment in high concentrations. Despite this fact, no up-to-date information on SPM levels exists for the capital of Chile, Santiago (7 million inhabitants). To address this knowledge gap, SPM sedimentation rates, including soluble and insoluble components, were measured at three different urban sites from July to November of 2016. We compare the measurements with ambient and meteorological information, as well as urban typology settings. Our results indicate SPM deposition rates between 2.5 and 3.9 g/(m 2 ⋅30 days). Only one site exceeded the national limit of 4.5 g/(m 2 ⋅30 days), but we found an increasing trend in all three sites. SPM and its insoluble sedimentation rates increased during warm and dry months and presented significant correlations with meteorological parameters. The highest sedimentation rates were measured at the location with the least permeable surfaces and the lowest green spaces, while the lowest sedimentation rates were found in the sites with abundant green spaces and permeable soil. No significant differences were detected in the soluble components. Our results suggest that SPM levels in Santiago are close to the national limit and may increase with climate change and urban expansion.
