“…Food crops grown in thallium contaminated areas can cause chronic thallium poisoning which is difficult to diagnose in the early stage and is easy to miss. (Liu et al 2017a). The main symptoms of chronic thallium poisoning are neurological impairment, loss of vision, hair loss, and possible teratogenicity and mutagenicity.…”

“…The Maximum Permissible Level of Tl in drinking water is fixed at 2 μg/L by the U.S. EPA [4], 0.8 μg/L by Canada and 0.1 μg/L by China and Russia [2,4]. The predominant source of Tl released into the environment is industrial activities utilizing Tl-bearing minerals, such as smelting of Pb, Cu, and Zn ores, rather than from facilities producing or using Tl compounds [1][2][3][4][5][6][7]. Tough Tl is highly toxic and has often been excluded from the list of metals to be supervised before 2010, when a serious Tl pollution incidence occurred in the northern branch of the Pearl River -the 3 rd longest river in China.…”

“…Tough Tl is highly toxic and has often been excluded from the list of metals to be supervised before 2010, when a serious Tl pollution incidence occurred in the northern branch of the Pearl River -the 3 rd longest river in China. Since then, Tlbearing wastewater discharge has been greatly controlled and regulated by the local Environmental Protection Bureau [1]. Worse still, rapid industrial development and general overlook of Tl pollution control in recent decades and outbursts of Tl pollution have been successively reported over several different provinces in China [5].…”

Thallium (Tl) is a typical trace metal of extreme high toxicity. As a concomitant element, Tl is widely found in various sulfide minerals and K-containing rock minerals. The outburst of Tl pollution in drinking water sources of the northern branch of the Pearl River in China as reported in 2010 has greatly aroused public concerns about Tl pollution in China. Apart from typical sources of Tl pollution such as Pb and Zn smelting and the mining and utilization of Tl-containing pyrite ores, the steel-making industry was discovered a new significant source that contributed to this Tl pollution incidence. Thallium contents in raw materials, fly ash and wastewater collected from a typical steel-making enterprise were determined by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that Tl contents (0.02-1.03 mg/kg) are generally low in the raw materials, while fly ash samples have generally enriched Tl levels (1.31-6.45 mg/kg). Wastewater obtained from the dedusting process of the sintering furnace also exhibited excessive Tl levels (574-2130 μg/L). All these results suggested a possible release and gasification of Tl compounds from the raw materials under high temperatures (>800ºC) during the sintering processes, which were then accumulated in the flue gas and fly ash and washed into the wastewater by wet dedusting. Lime precipitation method is not effective for removing Tl from wastewater, since Tl mostly is present as dissolved Tl + in the water. The study initiated a preliminary design of a fast and effective treatment method for Tl removal from Tl-containing industrial wastewater by using a deep oxidation system.

Heavy metals are rich in seleniferous areas; however, the bioaccumulation and health risk of heavy metals are poorly understood, given the fact that selenium (Se) can inhibit the phytotoxicity and bioavailability of many heavy metals. The present study investigated the bioaccumulation of heavy metals in the soil–rice system in the Enshi seleniferous area of central China. Soils were contaminated by Mo, Cu, As, Sb, Zn, Cd, Tl, and Hg caused by the weathering of Se‐rich shales. Among these heavy metals, Cd and Mo had the highest bioavailability in soils. The bioavailable fractions of Cd and Mo accounted for 41.84 and 10.75% of the total Cd and Mo in soils, respectively. Correspondingly, much higher bioaccumulation factors (BAFs) of Cd (0.34) and Mo (0.46) were found in rice, compared with those of other heavy metals (Zn 0.16, Cu 0.05, Hg 0.04, and Sb 0.0002). For the first time—to our knowledge—we showed that the uptake of Hg, Cd, and Cu by rice could be inhibited by the presence of Se in the soil. The probable daily intake (PDI) of Se, Cd, Mo, Zn, and Cu through consumption of local rice was 252 ± 184, 314 ± 301, and 1774 ± 1326 μg/d; and 7.4 ± 1.68 and 0.87 ± 0.35 mg/d, respectively. The high hazard quotients (HQs) of Mo (1.97 ± 1.47) and Cd (5.22 ± 5.02) suggested a high risk of Cd and Mo for Enshi residents through consumption of rice.
