“…MSWI in southern Taiwan was studied to observe the dioxins and DL-PCBs level in y ash. The reported dioxins concentration was ranged from 1.97 x 10 − 3 to 8.93x 10 − 1 ng I-TEQ/g (median: 4.52 x 10 − 2 ng I-TEQ/g) (Hsieh et al 2018), ], this was corroborated with other countries including Taiwan (laboratory waste: 0.02-1.86 ng I-TEQ/g), and Northeast China ( y ash from MSWI: 3.2-800.1 ng I-TEQ/g), respectively (Li et al 2016, Wu et al 2014).…”

This study showed the distribution of PCDD/Fs and DL-PCBs in bovine milk and ash samples collected from urban and rural areas of south Tamil Nadu and one milk sample from Japan. Around 25 bovine milk samples and 16 ash samples were collected accordingly. The total TEQ for PCDD/Fs and DL-PCBs were ranged from 0.028 to 7.331 pg TEQ/g fat. Some of the districts were showed higher PCDD/Fs and DL-PCBs concentration in milk and ash samples. Further, BM14 (7.331 pg-TEQ/g fat) and BM21 (6.406 pg-TEQ/g fat) area exceed level of PCDD/Fs and DL-PCBs than WHO regulation limits (6 pg-TEQ/g fat). Likewise, BM3, BM8, and BM14 areas showed higher milk contamination by dioxins, which exceed the WHO regulation limit (3pg-TEQ/g fat). Similarly, the total TEQ for PCDD/Fs and DL-PCBs in ash samples was ranged from 0.02 to 1.2 ng TEQ/g. AS3 (1.2 ng-TEQ/g) and AS11 (1.06 ng-TEQ/g) areas showed higher dioxins and DL-PCBs among the samples. This study provides an overview of dioxins and dioxin-related compounds contamination in bovine milk and ash samples. Further, the CALUX assay method validation has simplifies the monitoring of dioxin contamination in the environment.

“…The process of sample analysis has been reported in our previous study (Li et al, 2016a) and the results indicated that the performance of the Chinese national standard method (HJ77.2e2008) was comparable with USEPA method (USEPA, 1999;. Briefly, the stack gas samples were transferred into Soxhlet with toluene.…”

“…CFA can cause serious dust pollution [1], and the toxic elements contained in CFA can leach into soil and cause serious secondary pollution [2][3][4]. Millions of tonnes of CFA, containing high proportions of aluminum and lithium, are released each year from coal-fired power stations in the Inner Mongolia, Ningxia, and Shanxi provinces in northern China [5][6][7][8], which is illustrated in Figure 1.…”

A novel technique was developed for the recovery of lithium and aluminum from coal fly ash using a combination of pre-desilication and an intensified acid leaching process. The main components of the high-aluminum fly ash were found to be Al 2 O 3 and SiO 2 , and the Al/Si ratio increased from 1.0 to 1.5 after desiliconization. The lithium content of the coal fly ash met national recycling standards. The optimal acid leaching conditions, under which the leaching efficiencies of lithium and aluminum were 82.23% and 76.72%, respectively, were as follows: 6 mol/L HCl, 1:20 solid to liquid ratio, 120 • C and 4 h. During the hydrochloric acid pressure leaching process, spherical particles of desilicated fly ash were decomposed into flakes. Part of the mullite phase was dissolved, and most of the glass phase leached into the liquor. The generation of the silicates hindered lithium transport, which decreased the leaching rate of lithium. This work suggests that the preprocessing is a promising option for effective recovery of high-aluminum and fly ash-associated lithium.
