Capture, detection and removal of persistent organic pollutants (POPs) from water, air soil are among the hot topics research in environmental science. Here we report first example indirect ultrasensitive polychlorinated biphenyls obtained by analysing Raman signals silver-cyclodextrin supracrystals resulting drying-induced aggregation plasmonic alginate bubbles. Principal component analysis al...

Concentrations of polychlorinated dibenzo-p-dioxins (dioxins)(PCDDs) and polychlorinated dibenzofurans (PCDFs)(furans) in sediments from Port Jackson ranged from 32 to 4352 pg WHO-TEQ DF g(-1)dw with a mean of 712 pg g(-1)dw. Maximum total dioxins plus furans concentrations in this sediment was 6,290,000 pg g(-1)dw, which is the highest recorded in Australia and among the highest reported for s...

 Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (“dioxins”) is a term used to refer to a group of 210 compounds with similar chemical structures  Most of these compounds pose no health hazard at the levels commonly found but 17 of them are of more toxicological concern  The most toxic dioxin is 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and most of the available data ...
