Naphthalene

Status: No national drinking water standard exists

 

Naphthalene is a polycyclic aromatic hydrocarbon, or PAH, released from combustion of fossil fuels and waste incinerators, and also used as a moth repellent. PAHs increase the risk of cancer; damage the immune, nervous and reproductive systems; and can harm developing fetuses.
