For example, olfactory neuron loss (ONL) is one of the most sensitive end points seen in subchronic rodent hydrogen sulfide (H\n                    <jats:sub>2<\/jats:sub>\n                    S) studies and has been used by several agencies to derive health-protective toxicity values. Alternative methods that rely on computational fluid dynamics (CFD) models to account for the influence of airflow on H\n                    <jats:sub>2<\/jats:sub>\n                    S-induced ONL have been proposed. The use of CFD models result in toxicity values that are less conservative than those obtained using more traditional methods. These alternative approaches rely on anatomy-based CFD models. Model predictions of H\n                    <jats:sub>2<\/jats:sub>\n                    S delivery (flux) to the olfactory mucosal wall are highly correlated with ONL in rodents.
