Being hydrophobic, chlordane adheres to soil particles and enters groundwater only slowly, owing to its low solubility (0.009 ppm). It requires many years to degrade. [16] Chlordane bioaccumulates in animals. [17] It is highly toxic to fish, with an LD 50 of 0.022–0.095 mg/kg (oral).
At 101.325 kPa (abs) and 15 °C (59 °F), air has a density of approximately 1.225 kg/m 3 (0.0765 lb/cu ft), which is about 1 ⁄ 800 that of water, according to the International Standard Atmosphere (ISA).
After identification of the 14 C residues in organs of the goats, such as the liver, heart, kidneys, muscles and fat tissue, it appeared that 0.03 ppm or less of the 14 C compounds present was non-metabolized ethion. The metabolites ethion monoxon and ethion dioxon were also not detected in any samples with a substantial threshold (0.005-0.01 ppm).
The resulting compound is known to absorb water and carbon dioxide, and it may be used to remove vapors of these compounds from closed atmospheres. [23] Similar observations are made during reaction between lutetium and water (slow when cold and fast when hot); lutetium hydroxide is formed in the reaction. [ 24 ]
The 1 H and 13 C NMR chemical shifts are respectively 1.873 and 1.756 ppm and are 28.46 and 37.85 ppm. [28] The simplicity of these spectra is consistent with high molecular symmetry. Mass spectra of adamantane and its derivatives are rather characteristic. The main peak at m/z = 136 corresponds to the C 10 H + 16 ion.
In crude oil, concentrations up to 1200 ppm have been reported. When such oil products are burned, traces of vanadium may cause corrosion in engines and boilers. [65] An estimated 110,000 tons of vanadium per year are released into the atmosphere by burning fossil fuels. [66] Black shales are also a potential source of vanadium.
