Article Synopsis
- - Chromium is found in various industrial solid wastes, which, when subjected to high-temperature thermal treatment, can transform low-toxicity Cr(III) into highly-toxic and mobile Cr(VI), endangering human health and the environment.
- - The paper discusses the different forms of chromium in solid waste, the mechanisms of oxidation and reduction between Cr(III) and Cr(VI), and the factors that influence the formation of Cr(VI) at elevated temperatures.
- - Methods to mitigate the oxidation of Cr(III) into Cr(VI) during thermal treatment include controlling system basicity and temperature, as well as considering the interactions with alkali and alkaline earth metals.
The aim of the present study was to evaluate human health and potential ecological risk assessment in the ger district of Ulaanbaatar city, Mongolia. To perform these risk assessments, soil samples were collected based on reference studies that investigated heavy element distribution in soil samples near the ger area in Ulaanbaatar city. In total, 42 soil samples were collected and 26 heavy metals were identified by inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS) methods.

A total of 78 samples was collected from a variety of functional areas. The geoaccumulation index (I) and integrated pollution index (IPI) were used in pollution assessment, while the health risk was scored using a hazard quotient () and health index (HI) for non-carcinogenic heavy metals, as well as a lifetime average daily dose () for carcinogenic heavy metals.
