“…These areas are regarded as important source regions of many air pollutants that pose significant health risks locally and regionally (Rajgopal, 2003;Lelieveld et al, 2001). Previous studies indicated that Hg emissions within south and southeast Asia, including southwestern China, have significant impacts on the distribution and deposition of atmospheric Hg in south and east Asia Mukherjee et al, 2009;Sheu et al, 2013;Fu et al, 2015;Zhang et al, 2012).…”

“…These influences have raised concerns about high atmospheric Hg levels in India and southwestern China, and increased Hg contents in the snow packs of Hindu Kush Himalayan-Tibetan glaciers (Loewen et al, 2005(Loewen et al, , 2007Kang et al, 2016). Previous studies reported that the open biomass burning in forests and agricultural waste burning in southeast Asia are major sources of atmospheric Hg, aerosols and persistent organic pollutants in the region, which are subject to transboundary transport (Reid et al, 2013;Chang et al, 2013;Zhang et al, 2010Zhang et al, , 2015Sheu et al, 2013;Wang et al, 2015). However, studies with respect to Hg emissions in south and southeast Asia and the associated transboundary transport mediated by monsoonal weather are still lacking.…”

Abstract. To better understand the influence of monsoonal climate and transport of atmospheric mercury (Hg) in southwestern China, measurements of total gaseous mercury (TGM, defined as the sum of gaseous elemental mercury, GEM, and gaseous oxidized mercury, GOM), particulate bound mercury (PBM) and GOM were carried out at Ailaoshan Station (ALS, 2450 m a.s.l.) in southwestern China from May 2011 to May 2012. The mean concentrations (± SD) for TGM, GOM and PBM were 2.09 ± 0.63, 2.2 ± 2.3 and 31.3 ± 28.4 pg m −3 , respectively. TGM showed a monsoonal distribution pattern with relatively higher concentrations (2.22 ± 0.58 ng m −3 , p = 0.021) during the Indian summer monsoon (ISM, from May to September) and the east Asia summer monsoon (EASM, from May to September) periods than that (1.99 ± 0.66 ng m −3 ) in the non-ISM period. Similarly, GOM and PBM concentrations were higher during the ISM period than during the non-ISM period. This study suggests that the ISM and the EASM have a strong impact on longrange and transboundary transport of Hg between southwestern China and south and southeast Asia. Several high TGM events were accompanied by the occurrence of northern wind during the ISM period, indicating anthropogenic Hg emissions from inland China could rapidly increase TGM levels at ALS due to strengthening of the EASM. Most of the TGM and PBM events occurred at ALS during the non-ISM period. Meanwhile, high CO concentrations were also observed at ALS, indicating that a strong south tributary of westerlies could have transported Hg from south and southeast Asia to southwestern China during the non-ISM period. The biomass burning in southeast Asia and anthropogenic Hg emissions from south Asia are thought to be the source of atmospheric Hg in remote areas of southwestern China during the non-ISM period.

“…Control Board in 2001 to shut down the factory after Palani Hills Conservation Council and Greenpeace exposed the company's attempt to sell glass contaminated with mercury to a scrap dealer. Former employees and activists alleged that in 18 years of operation, the factory exposed more than 600 workers to toxic mercury and at least 45 workers have died prematurely, and hundreds are suffering from nervous disorders, dental problems, vision and hearing impairments, skin problems, and memory loss (Rajgopal, 2003;Shah, 2021;Sharma, 2003). Two years after the shutdown of the factory, around 300 tons of contaminated waste generated by the factory in 18 years including glass-scrap with residual mercury, semifinished and finished thermometers, effluent treatment plant waste, and elemental mercury were extracted from the site.…”

Global value networks are often large, complex, and opaque. Understanding the relationships among stakeholders involved in these networks or organizations can be challenging. This card sort task provides an interactive way to engage participants in questioning the roles of stakeholders who are involved in a business ethics dilemma or an organizational product failure. This card sort task and discussion activity encourages participants to recognize that stakeholders may hold different knowledge, responsibility, or power; identify competing, conflicting, or complementary interests across stakeholders; articulate logical arguments; and engage in debate, compromise, and critical evaluation. This technique has been used successfully with undergraduate and postgraduate business, management, and social science students and is suitable for in-person and remote classes.
