The procedures of implementing tiered health risk assessment approach were introduced in detail, and took a large-scale site polluted by benzene in Beijing as an example, the difference on the remediation target of benzene in soil, as well as the corresponding soil remediation volume and costs, were compared. The results indicate that the benzene(More)
In the title compound, C(2)H(4)N(6)O, the planar [maximum deviation = 0.006 (2) Å] amino-tetra-zole group makes a dihedral angle of 83.65 (8)° with the formamide unit. In the crystal structure, inter-molecular N-H⋯N, N-H⋯O and C-H⋯N hydrogen bonds are responsible for the formation of a three-dimensional network.
In the crystal structure of the title compound, C(7)H(10)N(6)O(3), there are N-H⋯O, N-H⋯N and C-H⋯O inter-actions, generating a three-dimensional supra-molecular network structure. A short intermolecular O⋯C contact of 2.8994 (18) Å is alsopresent in the crystal structure, but no π-π contacts are observed.
