Element Mercury

Exposures to the toxic element mercury (Hg) are exceptionally high among recycling workers globally. Recycling is a growing sector in Colombia, yet workers who directly handle e-waste are often unaware of the risks of exposure to mercury from post-consumer lighting products (e.g., fluorescent lamps). This qualitative study aimed to understand how recycling workers perceive their own risks from mercury exposure and how they find information about these risks, through interviews (n = 35) at the three largest formal recycling facilities in Colombia. Workers’ risk perception was generally disconnected from their likely actual exposure to mercury, instead often seen juxtaposed to co-workers who worked more directly with hazardous waste. Recycling workers, who were predominantly men from lower-income socioeconomic backgrounds, had limited knowledge of health risks due to mercury exposure and were more likely to receive health-related information from informal sources. Over a third of interviewees had searched online for information about occupational health risks of mercury, but these searches were perceived as unsatisfactory due to information being difficult to find, not available in Spanish, or related to mercury exposure via seafood or mining rather than recycling. Workers expressed (over)confidence in personal protective equipment and concern about frequent employee turnover. This study points to weaknesses in environmental health literacy and public health communication around toxic exposures to mercury in the workplace. Stronger regulation and enforcement are needed to prevent toxic exposures and promote worker health equity.

In a combined synthetic, X-ray single-crystal and bond-theoretical study the phase widths of SrIn4 and the related Sr3In11 upon a sucessive substitution of indium against the more electronpoor, more electronegative and only slightly smaller element mercury have been studied. Along the 1 : 4 section Sr(In1-xHgx)4 the monoclinic structure of SrIn4 ( EuIn4-type structure) is stable up to x =0.14(1) ( SrIn3.44Hg0.56: monoclinic, C2/m, a = 1208.3(6), b = 502:5(2), c = 997.7(6) pm, b = 115.16(3)°, Z = 4, R1 = 0.0324). Further increased mercury content results in a distinct stability region of the very common BaAl4 structure type (tetragonal, I4=mmm, Z = 2), which starts at x =0.241(7) ( SrIn3.04Hg0.96: a = 4694(2), c = 1246.4(7) pm, R1 = 0.0374) and reaches up to the fully ordered compound SrIn2Hg2 (x =0.5: a = 456.4(3), c = 1273.5(11) pm, R1 = 0.0572). Unexpectedly, in the small composition range from x=0.68(1) to 0.758(6) ( SrIn1.16Hg2.84: a=1178.5(4), b = 495.20(12), c = 1016.8(4) pm, b = 119.67(2)°, R1 = 0.0542; SrIn0.97Hg3.03: a = 1167.30(4), b = 495.32(2), c = 1018.50(3) pm, b = 119.657(2)°, R1 = 0.0426) the EuIn4 structure type exhibits a further small stability range. The structures of the two slightly different In- and Hg-rich variants of the EuIn4 type are described and compared, indicating the similarities to the KHg2 (layers of folded In=Hg ladders) and the BaAl4 structure type (flat square pyramids) as well as to the structure of elemental mercury (rhombohedra). From samples of an intermediate In=Hg ratio (e. g. x =0.55), the new 1 : 3 compound SrIn1.2Hg1.8 (monoclinic, C2=m, a = 1168.5(13), b = 497.0(4), c = 1471(2) pm, b = 92.07(10)°, Z = 8, R1 = 0.0818) is formed. It crystallizes in a new structure type, which - according to the compound’s composition - can be described as a stacking variant of the EuIn4 and the KHg2 structure type. In contrast to the wide stability ranges of the 1 : 4 compounds, only a very small substitution of In ranging up to only 6% of Hg is possible in the binary indide Sr3In11 ( Sr3In10.32(8)Hg0.68(8): La3Al11 structure type, orthorhombic, Immm, a = 487:6(2), b = 1140.2(5), c = 1421.1(7) pm, Z = 2, R1 = 0.0703). The formation, stability ranges and the In=Hg ‘coloring’ of the polyanions are discussed for all compounds taking into account geometric (radius ratios, molar volumes, Sr coordination polyhedra etc.) and electronic aspects, which have been evaluated using FP-LAPW band structure calculations.

In this paper, cobalt oxide was deposited on the surface of Activated Carbon Fiber (ACF) by adsorption and was then sintered. The effects of cobalt oxide on the properties of ACF were studied by XPS, FTIR, and XRD methods. Mercury removal performance was also investigated. 5% cobalt was well dispersed on the surface of ACF, and a variety of oxygen-containing groups had been enhanced. The chemical functional groups on the surface of ACF were changed to strengthen the adsorption and catalytic oxidation of ACF to the element mercury (Hg0). The measurement results showed that ACF coated with cobalt oxide had higher adsorption properties.
