Regarding this, what chemicals can cause methemoglobinemia?

Methemoglobinemia is commonly caused by exposure to medical substances, such as benzocaine and dapsone, that oxidize hemoglobin to MetHb; exhaust fumes from internal combustion engines; herbicides and pesticides; and chemicals, such as nitrobenzene and aniline [5-11].

What is blue blood disease?

In their case, blue skin was caused by a rare genetic disease called methemoglobinemia. Methemoglobinemia is a blood disorder in which an abnormally high amount of methemoglobin — a form of hemoglobin — is produced. Hemoglobin is the molecule in red blood cells that distributes oxygen to the body.

How is methemoglobinemia inherited?

Autosomal recessive congenital methemoglobinemia is caused by mutations in the CYB5R3 gene. This gene provides instruction for making an enzyme called cytochrome b5 reductase 3. This enzyme is involved in transferring negatively charged particles called electrons from one molecule to another.
