In 1994, we collected 36 soil samples and 61 sediment samples from southern Mississippi, USA. Each sample was analyzed for PCDDs and PCDFs by HRMS using either a polar or a non-polar HRGC column. Although most Cl4 Cl8 PCDDs and PCDFs were detecte

A sampling method for the determination of the particle-bound and dissolved PCDDs/Fs in the river Elbe is described. The suspended particulate matter (SPM) sample was taken by means of a centrifuge. For the water phase a sampling system with three mo

Different industrial processes in Sweden have been investigated regarding their emissions of PCDD/F to the environment. Levels, congener patterns and estimated annual emissions are compared for the samples analyzed. The results support the assumption

Analyses of sludge from graphite electrodes used in the chloralkali process show total levels of PCDFs as high as 650000 pg/g sludge. The levels of tetra-, penta-and hexaCDFs were found to be approximately the same. The levels for the corresponding P

One goal of the Swedish survey project is to discover possible sources of PCDD/F. Bottom sediment and pike were sampled at various sites near different types of industries along the coast line of two lakes and one river. The results show background l

In this study we have detected the α-amylase isoenzymes in the two barley varieties ‘Ingrid’ and ‘Pomo’. We further report on the effect of different pH and temperatures on the activities of the α-amylase I and II (following the nomenclatur
