Local Background

Abstract Coal-seam fire is a source of atmospheric mercury that is difficult to control. The Wuda Coalfield in Inner Mongolia, China, is one of the most severe coal fire disaster areas in the world and has been burning for more than 50 years. To investigate atmospheric mercury pollution from the Wuda coal fire, gaseous elemental mercury (GEM) concentrations and atmospheric particulate mercury (PHg) speciation were measured using a RA-915 + mercury analyzer and the temperature-programmed desorption (TPD) method. Near-surface GEM concentrations in the Wuda Coalfield and adjacent urban area were 80 ng m− 3 (65–90 ng m− 3) and 52 ng m− 3 (25–95 ng m− 3), respectively, which are far higher than the local background value (22 ng m− 3). PHg concentrations in the coalfield and urban area also reached significantly high levels, at 33 ng m− 3 (25–45 ng m− 3) and 22 ng m− 3 (14–29 ng m− 3), respectively. There is no clear evidence that PHg combines with organic carbon (OC) or elemental carbon (EC), but PHg concentration appears to be controlled by air acidity. PHg mainly exists in inorganic forms, such as HgCl2, HgS, HgO, and Hg(NO3)2·H2O. This work can provide references for the speciation analysis of atmospheric PHg and the safety assessment of environmental mercury.

Arsenic In Groundwater

In contrast to Mongolia, family-owned land in Inner Mongolia is separated by fences, preventing the free movement of nomads and leading people to rely heavily on the same source of groundwater for their domestic water needs.

Early State

In current day South Korea pseudohistory pertaining to early Korea and northern East Asia has reached epidemic proportions. Its advocates argue the early state of Chosŏn to have been an expansive empire centered on mainland geographical Manchuria. Through rationalizing interpretations of the traditional Hwan’ung- Tan’gun myth, they project back the supposed antiquity and pristine nature of this charter empire to the archaeological Hongshan Culture of the Neolithic straddling Inner Mongolia and Liaoning provinces of China. Despite these blatant spatial and temporal exaggerations, all but specialists of early Korea typically remain hesitant to explicitly label this conceptualization as “pseudohistory.” This is because advocates of ancient empire cast themselves as rationalist scholars and claim to have evidential arguments drawn from multiple textual sources and archaeology. They further wield an emotive polemic defaming the domestic academic establishment as being composed of national traitors bent only on maintaining a “colonial view of history.” The canon of counterevidence relied on by empire advocates is the accumulated product of 20th century revisionist and pseudo historiography, but to willing believers and non-experts, it can easily appear convincing and overwhelming. Combined with a postcolonial nationalist framing and situated against the ongoing historiography dispute with China, their conceptualization of a grand antiquity has gained bipartisan political influence with concrete ramifications for professional scholarship. This paper seeks to introduce and debunk the core, seemingly evidential, canon of arguments put forward by purveyors of Korean pseudohistory and to expose their polemics, situating the phenomenon in a broader diagnostic context of global pseudohistory and archaeology.
