Tracking quicksilver: estimation of mercury waste from consumer products and subsequent verification by analysis of soil, water, sediment, and plant samples from the Cebu City, Philippines, landfill.

Source attribution of mercury (Hg) is critical for policy development to minimize the impact of Hg in wastes. Mercury content of consumer products and its subsequent release into the waste stream of Cebu City, Philippines, is estimated through surveys that employed validated, enumerator-administered questionnaires. Initially, a citywide survey (n = 1636) indicates that each household annually generates 1.

(N,N-diethyldithiocarbamato)[tris(3,5-dimethylpyrazol-1-yl)hydroborato]copper(II): a new copper(II) dithiocarbamate compound with the classic Tp(Me2) scorpionate.

The title complex, [Cu(C5H10NS2)(C15H22BN6)] or (Tp(Me2))Cu(S2CNEt2), incorporating the classic Tp(Me2) scorpionate, is relevant to blue copper protein models and to Cu extraction from waste treatment and mine-tailing leachate. The IR and UV-Vis spectra are consistent with the crystal structure.
