I'm not sure what perspective that offers as it says nothing (or nothing easily interpretable) about the potential for public health impact, which is, after all, the topic under discussion. Also, for accuracy: in engines, TEL is burnt in the presence of lead-scavenging additives. This means that rather than elemental lead, engine exhausts produce soluble lead compounds such as lead(II) bromide and lead(II) chloride which have much greater potential for atmospheric pollution and human toxicity.
