Antimony from pellet alloys is dispersed in the soil of the shooting fields, and a secondary Sb phase appears in the weathering crusts as long as the corroding bullets are present in soil, thus presenting an important source of bioavailable Sb in the environment (Mera et al., 2015).
The information processing models assume serial processing of stimulus inputs. Serial processing effectively means one process has to be completed before the next starts. Parallel processing assumes some or all processes involved in a cognitive task(s) occur at the same time.
Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb 2 O 3 dissolves in aqueous solutions with hydrolysis.
Process leading to the selection of antimony(III) xide for review As per the process for preparation of the RoC, the Office of the Report on Carcinogens (ORoC) released a draft concept document, "Antimony xide," which outlined the rationale and proposed the approach for the review, for public comment.
