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.
The sharp acceleration in CO 2 emissions since 2000 to more than a 3% increase per year (more than 2 ppm per year) from 1.1% per year during the 1990s is attributable to the lapse of formerly declining trends in carbon intensity of both developing and developed nations. China was responsible for most of global growth in emissions during this ...
Here is the test. Three scoring systems are in use, called points, Eliteness, and RC. A bubble like this - (1) gives points, if it says Eliteness or RC, it gives Eliteness or RC.
