Exposure to the coplanar stereoisomer 3,3',4,4',5,5'-hexabromobiphenyl (but not the non-coplanar stereoisomer) in genetically susceptible mice is known to cause immunotoxicity and disorders related to the central nervous system, and even at doses as low as 2.5 mg/kg, excess neonatal fatalities are observed (LD 50 is from 5–10 mg/kg).

On December 9, 2021, at The Game Awards, Google announced that Google Play Games beta would launch in early 2022, bringing Android games to Windows PCs and laptops. [10] The minimum specification requirements to run Google Play Games are currently Windows 10 or later operating system with an integrated graphics card and quad-core CPU that can access Google Play Games beta (previously octo-core ...
Free Fire Max is an enhanced version of Free Fire that was released in 2021. [71] [72] It features improved High-Definition graphics, sound effects, and a 360-degree rotatable lobby. Players can use the same account to play both Free Fire Max and Free Fire, and in-game purchases, costumes, and items are synced between the two games. [73]
Concentration measurements are usually determined from a working curve after calibrating the instrument with standards of known concentration. The main advantages of the graphite furnace comparing to aspiration atomic absorption are the following: The detection limits for the graphite furnace fall in the ppb range for most elements
Many environmental protection agencies have issued regulations that limit the concentration of pollutants in gaseous emissions and define the reference conditions applicable to those concentration limits. For example, such a regulation might limit the concentration of NOx to 55 ppmv in a dry combustion exhaust gas corrected to 3 volume percent O 2.
1 volume percent = 10,000 ppmv (i.e., parts per million by volume) with a million being defined as 10 6. Care must be taken with the concentrations expressed as ppbv to differentiate between the British billion which is 10 12 and the USA billion which is 10 9 (also referred to as the long scale and short scale billion, respectively).

Fluorescein aqueous solutions, diluted from 10,000 to 1 parts-per-million in intervals of 10 fold dilution. At 1 ppm the solution is a very pale yellow. At 1 ppm the solution is a very pale yellow. As the concentration increases the colour becomes a more vibrant yellow, then orange, with the final 10,000 ppm a deep red colour.
