Nov. 13, 2023: An additional lab, SGS Galson, received samples of the air in Poe Hall. The company reported the results to NC State on Nov. 14. The results did not appear to indicate ...
Bioremediation of PCBs is the use of microorganisms to degrade PCBs from contaminated sites, relying on multiple microorganisms' co-metabolism. Anaerobic microorganisms dechlorinate PCBs first, and other microorganisms that are capable of doing BH pathway can break down the dechlorinated PCBs to usable intermediates like acyl-CoA or carbon ...
One estimate (2006) suggested that 1 million tonnes of PCBs had been produced. 40% of this material was thought to remain in use. [2] Another estimate put the total global production of PCBs on the order of 1.5 million tonnes. The United States was the single largest producer with over 600,000 tonnes produced between 1930 and 1977.

N.C. State now anticipates Poe Hall will be closed through at least the end of the 2024-25 academic year. NC State reveals plans to remedy toxic PCBs in Poe Hall. Here’s what’s being proposed.
The EPA will be evaluating samples taken over the last five years to monitor the success of GE's cleanup of carcinogen PCBs in the water. Hudson River recovery: EPA begins next PCB contaminant ...
Worst-case analysis is the analysis of a device (or system) that assures that the device meets its performance specifications. These are typically accounting for tolerances that are due to initial component tolerance, temperature tolerance, age tolerance and environmental exposures (such as radiation for a space device).
Severe PCB corrosion from a leaky PCB mounted Ni-Cd battery. Printed circuit boards (PCBs) are vulnerable to environmental influences; for example, the traces are corrosion-prone and may be improperly etched leaving partial shorts, while the vias may be insufficiently plated through or filled with solder. The traces may crack under mechanical ...
