Human scalp hair samples were collected and used to assess exposure to toxic elements and essential elements in the state of North Carolina, USA using accelerated microwave assisted acid digestion and inductively coupled plasma optical emission spectroscopy (ICP-OES). The figures-of-merit of the ICP-OES were appropriate for elemental analysis in scalp hair(More)
In the structure of the title compound, [Zn(C8H6NO4)2(C3H10N2)2], the Zn(II) atom is located on a center of symmetry with one independent Zn-O distance of 2.199 (2) Å, and two Zn-N distances of 2.157 (2) and 2.144 (2) Å. The overall coordination geometry around the Zn(II) atom is octa-hedral. Several types of hydrogen-bonding inter-actions are evident. Both(More)
