General description
PCB No 18 belongs to the class of polychlorinated biphenyls, which exist as persistent contaminants in environmental matrices and food products.
Application
PCB No 18 may be used as an analytical reference standard for the determination of the analyte in:
- environmental samples using glass capillary gas-chromatography with electron capture detection
- environmental matrix standard reference materials using supercritical fluid extraction/soxhlet extraction combined with gas chromatography coupled to two electron capture detection systems
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Polychlorinated biphenyls (PCBs) have been known as serious environmental pollutants, causing developmental delays, motor dysfunction, and decrease in brain dopamine level in humans and animals. We have investigated the effects of a PCB congener, 2,2',6-trichlorobiphenyl (PCB 19) on contractile force

Adult female houseflies (Musca domestica) were topically dosed with 10, 15, and 20 micrograms of 2,2',5-trichlorobiphenyl (PCB-18) in acetone at 1, 5, and 15 days following emergence. These doses caused a significant decrease in the mean survival time in 5-day-old
