# is there a lead compound that crosses the blood-brain barrier when ingested?

for example mercury oxide has neurotoxic properties but isn't organic so, it isn't soluble in lipids and so doesn't cross the blood brain barrier when ingested, however, methylmercury chloride is organic and soluble in lipids thus it can cross the blood brain barrier

• Do you mean "lead" as in the element $\ce {Pb}$ or lead as e.g. in "hit to lead compound"? What do you plan to do with it (as you asked about how easy it would be to obtain) – K_P Nov 2 '14 at 14:11
• i mean the element Pb, i am building octane generators and need tetraethyllead, but i am also researching the role of lead in such generators, since i am obsessed with health i want to establish a list of how different lead compounds affect the body.. – user9603 Nov 2 '14 at 14:28
