Interesting you mention mercury:
"HOUSTON, Texas (KTRK) – One person has been taken into custody by the FBI for questioning in connection with a mercury spill Sunday in west Houston, authorities said.
FBI Houston says the person will not be identified at this time since he has not been charged. Around 60 people were decontaminated as a precaution following the discovery of the heavy metal mercury at a west Houston shopping center located in the area of Westview Drive and West Sam Houston Parkway."
