“…The average concentrations of coarse and fine particles released during manual dismantling were about 3.1 and 2.2 times higher than those during no recycling activity whereas there were no significant differences in concentrations of ultrafine particles. Coarse and fine particles likely resulted from the fragments of e-waste during disassembly which is consistent with the results of previous studies [8,14]. It was reported that particle size distribution was influenced by types of dismantling tools and material compositions of e-waste.…”

“…The HQ values of Mn bound on fine, coarse particles and PM 10 for both males and females from thermal cutting and burning of cable sheath activities were higher than 10, which points to high chronic risk whereas those attached on ultrafine particles were higher than 1. In this study, the HQ values of Pb and Mn from manual dismantling were similar to the results of Papaoikonomou et al [14]. whereas that of Cr was about 4,000 times higher than the previous work [14].…”

“…It was also found that small household e-waste recycling workshops can cause more severe heavy metal pollution than large-scale e-waste recycling plants [13]. Previous work indicated that manual dismantling emitted atmospheric particulate-bound heavy metals such as chromium (Cr), copper (Cu), iron (Fe), lead (Pb), manganese (Mn) and zinc (Zn), into the environment [10][11][12]14]. It was reported that size distribution of particles obtained from thermal cutting of metals was associated with cutting parameters such as cutting materials, cutting methods, cutting conditions [15,16].…”

Concentrations and size distributions of atmospheric particulates and particulate-bound heavy metals in different inhalable fractions were studied in working areas during manual dismantling, thermal cutting and cable sheath burning activities. The particulate samples were collected on quartz fiber filters using an eight-stage cascade impactor with flow rate of 28.3 l min-1. Mass concentrations of the particles were measured in each size fraction. Heavy metals bound on the particles were extracted with acid digestion and then analyzed using Atomic Absorption Spectrophotometer. Risk assessment of worker exposure to the particles was determined. The results indicated that the concentrations of ultrafine (dae < 0.43 μm), fine (0.43 < dae < 2.1 μm) and coarse (2.1 < dae < 10 μm) particles were in the ranges of 14.49-62.04, 57.51-120.26 and 153.26–646.99 μg m−3 during manual dismantling, 363.41-1,011.95, 2,105.40-4,899.11 and 1,698.54-7,075.61 μg m−3 during thermal cutting and 364.73-1,694.72, 1,953.33-4,431.41 and 1,385.97-6,126.13 μg m−3 during cable sheath burning, respectively. The concentrations of PM2.1 and PM10 released from these activities did not exceed the OSHA PEL threshold limits. Heavy metals adsorbed on the particles (Fe, Cr, Zn, Cu, Pb, Mn) detected during manual dismantling did not exceed the TWA standard. Concentrations of Cr and Pb during cable sheath burning highly exceeded the standards whereas Pb concentrations during thermal cutting slightly exceeded the standard. The heavy metals released from these recycling activities were more enriched on coarse mode than fine mode. Inhalation exposure to Cr, Pb and Mn posed a potential health risk to the workers.

“…Extremely high levels were reported for workers burning e‐waste in Thailand where PM 2.5 and PM 10 levels averaged 2,774 ± 4,173 and 3,215 ± 4,858 μg/m 3 (N = 33) (Bungadaeng et al, 2019). Indoor PM 10 levels measured in several e‐waste recycling plants averaged 247–651 μg/m 3 (Papaoikonomou et al, 2018). These studies note the importance of combustion (especially open burning of waste, circuit boards, wires/cables, Styrofoam, etc.)…”

Air Quality Impacts at an E‐Waste Site in Ghana Using Flexible, Moderate‐Cost and Quality‐Assured Measurements

Air quality information is scarce in low‐ and middle‐income countries. This study describes the application of moderate cost approaches that can provide spatial and temporal information on concentrations of particulate matter (PM) needed to assess community and occupational exposures. We evaluated PM levels at the Agbogbloshie e‐waste and scrap yard site in Accra, Ghana, and at upwind and downwind locations, obtaining both optical and gravimetric measurements, local meteorological data and satellite aerosol optical depth. Due to overload issues, the gravimetric 24‐hr samplers were modified for periodic sampling and some optical data were screened for quality assurance. Exceptionally high concentrations (e.g., 1‐hr average PM10 exceeding 2000 μg/m3) were sometimes encountered near combustion sources, including open fires at the e‐waste site and spoil piles. 24‐hr PM2.5 levels averaged 31, 88 and 57 μg/m3 at upwind, e‐waste and downwind sites, respectively, and PM10 averaged 145, 214 and 190 μg/m3, considerably exceeding air quality standards. Upwind levels likely reflected biomass burning that is prevalent in the surrounding informal settlements; levels at the e‐waste and downwind sites also reflected contributions from biomass combustion and traffic. The highest PM levels occurred in evenings, influenced by diurnal changes in emission rates, atmospheric dispersion and wind direction shifts. We demonstrate that moderate cost instrumentation, with some modifications, appropriate data cleaning protocols, and attention to understanding local sources and background levels, can be used to characterize spatial and temporal variation in PM levels in urban and industrial areas.

“…13,14 Earlier studies have found the indoor PM 10 concentration in the dismantling plant for the waste of electrical and electronic equipment cities. 15 Another study detected PM 10 around e-waste burning and industrial sites of Moradabad, India, where it was highest at industrial sites, and at e-waste burning site, it was higher than residential sites. 13 There is some evidence that particulates could cause serious harm to humans via inhalation exposure, for example, bronchial irritation, inflammation, increased reactivity, reduced mucociliary clearance, reduced macrophage response.…”

The PM10 contributed in the e-waste dismantling community at Banmaichaiyaphot District, Buriram Province, was investigated due to the e-waste dismantling houses randomly located neighboring non-e-waste dismantling houses. The sampling was performed at non- and e-wastes dismantling houses and compared with the reference house in Daengyai subdistrict. The 24-hour average outdoor PM10 concentrations (81.957 ± 18.724 μg/m3) at e-waste dismantling sites were higher than those of the non-e-waste dismantling houses (80.943 ± 32.740 μg/m3) and control house (36.717 ± 19.516 μg/m3). The 24-hour average indoors PM10 concentrations of the e-waste dismantling houses (116.171 ± 64.635 μg/m3) showed higher concentrations than those of the non-e-waste dismantling (113.637 ± 64.641 μg/m3) and reference house (70.907 ± 22.464 μg/m3), but there were no statistically significant differences ( P > .05). Both indoor and outdoor PM10 concentrations between non- and e-waste dismantling houses did not have significant differences, whereas those of non- and e-waste dismantling houses were significantly higher than that of the reference house locating approximately 5 km away. The positive correlation between indoor and outdoor concentrations of non- and e-waste dismantling houses was satisfactory significant with the r of .613 and .825, respectively. The results indicate that the existing indoor PM10 of either non- or e-waste dismantling houses could result from neighborhood e-waste dismantling.
