In the structure of the title compound, C(22)H(27)Cl(3)O(2), which is the 4-but-oxy-phenyl analogue of the insecticidally active 4-meth-oxy-phenyl compound meth-oxy-chlor, the dihedral angle between the two benzene rings is 79.61 (11)°. Present also in the structure is an intra-molecular aromatic C-H⋯Cl inter-action.
Total atmospheric Hg contamination in a French mountainous catchment upstream from a chlor-alkali industrial site was assessed using Hg concentrations in the deepest soil horizon, in the stream bottom sediments, in river waters and in bryophytes. The natural background level of Hg content deriving from rock weathering was estimated to 32 ng g(-1) in the deepest soil layers. The soils appear to ...
BACKGROUND The paper presents the evaluation of soil contamination with total, water-available, mobile, semi-mobile and non-mobile Hg fractions in the surroundings of a former chlor-alkali plant in connection with several chemical soil characteristics. Principal Component Analysis and Cluster Analysis were used to evaluate the chemical composition variability of soil and factors influencing the...
