During recycling, arsine can be released if scrap containing arsenic is melted down with the “maintenance-free” batteries containing calcium. When the scrap mixture is in the molten state, calcium arsenide is formed. As cooling occurs, the calcium arsenide 20
Nutritional impact of elevated calcium transport activity …
These compounds can bind the calcium freely, and some plants also can bind calcium during the growth process (18–20). In the case of spinach, a poor source of bioavailable calcium, the incorporation of a 45 Ca tracer in bone is reduced by 50% in the intrinsically labeled diets compared with the extrinsic diets when fed to rats or mice ( 14 , 15 ).
Bromine - Wikipedia
Bromine is a chemical element with the syol Br and atomic nuer 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those
