KONSENTRASI POLYCHLORINATED BIPHENYLS (PCBS) DAN POLYCHLORINATED DIBENZO-P-DIOXINS/POLYCHLORINATED DIBENZOFURANS (PCDDS/FS) DALAM AIR DARI DAERAH PERKOTAAN JABODETABEK

Determination of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) in water samples from Jabodetabek urban area was conducted. In the results, a unique pattern were found interestingly in Ciliwung river, Pluit, Jakarta, where decachlorinated biphenyl (PCB IUPAC #209), and dichlorinated biphenyl (PCB IUPAC #11) were detected at relatively high concentrations as 406.77 ng/L and 6.38 ng/L, respectively. This congener pattern is different with commercial PCB mixtures, such as arochlor, kanechlor, or chlophen. Octachlorinated dibenzo-p-furan (OCDF) was also detected at a significant concentration in this water as 3.10 ng/L. Decachlorinated biphenyl (PCB IUPAC #209) and OCDF were associated with industrial by-products. Meanwhile, dichlorinated biphenyl (PCB IUPAC #11) was associated with colour pigment which widely used in consumer goods, such as paint and printed ink. Thus, PCBs and PCDD/Fs contamination might have arisen from industrial by-products where various industries located near sampling point. Keywords: polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins /polychlorinated dibenzo-p-furans (PCDDs/Fs), waters, Jabodetabek, industrial by-products.

Correlation between PCDD/F, PCB and PCBz Formed by De Novo Synthesis

Large amounts of polychlorinated dibenzo-p-dioxin and furans (PCDD/F), polychlorinated biphenyls (PCB) and polychlorinated benzenes (PCBz) were formed by de novo synthesis using model ashes. The de novo synthesis was affected by SO2and H2O. Knowledge of congener pattern and homologue profiles of PCDD/F, PCB and PCBz is help for elaborating the mechanism of formation and influence of the toxic compounds formed by de novo synthesis. By the help of the component analysis (CA) the best correlated congeners are effectively detected. Various good correlated pairs between PCDD/F, PCB and PCBz have been elaborated by using linear regression between the 15 samples. It was found that a good correlation between PCBz and PCDF.
