“…Different source apportionment (Li et al, 2014;Ma et al, 2016), methodologies (Chen et al (2016); Shi et al (2016); Meˇciarová et al (2017); Lee et al (2018), and instruments (Jiao et al, 2015;Van den Bossche et al, 2016;Zikova et al, 2017;Lee et al, 2018) have been used to determine and identify air pollution parameters. In Nigeria, many studies have not been done on indoor air pollution in Nigeria, but few literates obtained were done in Enugu (Ezezue and Diogu, 2017), Warri (Akpofure, 2015), Ile -Ife (Afolabi et al, 2016), Ido Ekiti (Ayodele et al, 2016), No report has been found for indoor pollution from Akure. On this note, the aim of the study was to assess the HCHO, TVOC, PM 1 , PM 2.5 , and PM 10 in Akure, the relationship between the weather and the pollutants would be determined, the results would be subjected to multivariate analysis, and the potential toxicity of the pollutants would also determined.…”

Air quality has been a major concern throughout the world, Nigeria inclusive. The monitoring of air quality involves indoor and outdoor air quality. In this study, our concern was on indoor air quality. The aim of this study was to assess the air quality of residential homes (17), classrooms (3), hospitals (2), offi ces (5), Shops (2), and laboratories (5) in Akure, Nigeria in terms of formaldehyde (HCHO), total volatile organic compound (TVOC), Particulate matter (PM 1.0 ; PM 2.5 , and PM 10 ). A Multifunction Air Detector was used for the assessment using the manufacturers' procedures and the locations were identifi ed using a Mini GPS. The results revealed as follows: HCHO (0.001-0.030 mg/ m 3 ), TVOC (0.003-362 mg/m 3 ), PM 1.0 (004-014 μg/m 3 ), PM 2.5 (006-020 μg/m 3 ), and PM 10 (006-022 μg/m 3 ). The results obtained were below the 24 h pollution recommended standards (0.1 mg/m 3 -HCHO; TVOC; 10-20 μ/m 3 PM) of EPA and WHO. Statistically, there were correlations within the pollutants and weather. The Indoor air quality (IAQ) depicted the areas as 'good,' and toxicity potential (TP) were below unity. Although the locations looked safe, it is recommended that constant monitoring of the indoors should be ensured and proper ventilation should be provided.

“…Air quality assessment through toxicity potential (T potential ) expresses the potential harm of a unit of pollutant released into the ambient air [3]. T potential computed from the ratio of measured pollutant concentration to the statutory limit set for such pollutant becomes worrisome when the value exceeds unity [15,20].…”

Spatial distribution and toxicity potential of gaseous criteria air pollutants in the ambient air around a typical haulage truck stop

This study investigated the spatial distribution and toxicity potential of gaseous criteria air pollutants in the ambient air around a typical haulage truck stop. ToxiRAE II Gas Monitors were used to monitor ambient concentrations of the criteria pollutants both for dry season and wet season. Five sampling points were considered, and a control sampling point was set at about 55 km away from the influence of activities of the truck stop. The results showed the dry season average 24-h concentrations of NO 2 with the range of 0.064-0.335 ppm while CO ranged between 0.919 and 4.911 ppm. During the wet season, the average concentrations of NO 2 ranged between 0.003 and 0.052 ppm, while CO concentration ranged between 0.000 and 4.798 ppm. The result showed average concentration of CO at all sampling points for both dry and wet season was below the Nigerian Federal Ministry of Environment (FEPA) national air quality standard of 10 ppm. However, average concentration of NO 2 at all sampling points during the dry season were above FEPA and World Bank air quality standards except sampling point D. The results also showed the toxicity potential which exceeded unity at some of the designated sampling points is of major concern especially among people with respiratory or heart disease. The study showed the haulage truck stop contributes greatly to the ambient gaseous criteria air pollutants.
