Bioaccumulation of Nonylphenol in Caged Mussels in an Industrial Coastal Area on the Swedish West Co a transect away from the wastewater outlet of a chemical plant on the west coast of Sweden. The highest tissue residue concentration of NP was found in mussels from the deep cages close to and just north of the outlet, which is the main direction of the water current. In a test performed at the sam

Transport and Distribution of DDT and PCB in the Upper Sado Estuary, and Accumulation in Oysters: Imry. The longitudinal distribution of DDT residues in suspended sediments was caracterized by a downward decrease. During most of the year, DDT levels ranged from 3 to 12 ng.g., but in winter it increased up to 87 ng.g.. For PCB, a minimum (in general, < 5 ng.g.) centered in the turbidity maximum zon

The Role of Capillary GC - Hyphenated Techniques in Water Analysisomatography. In this contribution, hyphenation is discussed in a broader sense i.e. all techniques coupled online to the capillary GC separation column are considered as hyphenated techniques. The keyword in separation and analytical method optimization is “selectivity”.

Application of AMD to the Determination of Crop-Protection Agents in Drinking Water - Fundamentals atic detection and determination of crop-protection agents. The distance migrated is very reproducible (on the same HPTLC plate and on different ones), so that a narrow interval window is adequate. Screening and confirmation gradients, coupled with reflectance spectroscopy (multiwavelength scanning)

Liquid Chromatographic Strategies for the Determination of Pesticides in the Aquatic Environments. Methods based on liquid-liquid extraction and HPLC post-column extraction are reported for the analysis of triazine, chlorinated phenoxyacids and amphoteric pesticides in water samples. Clean up methods involving Florisil and gel permeation chromatography are used for isolation of organophosphoru

Multiresidue Analysis of Pesticides in Drinking Water and Related Sampleside, and an MAC of 0.5 μg 1. for so-called total pesticides. Problems arise in the development of suitable methods because of two basic difficulties; there are hundreds of pesticides that could be monitored and the MAC sets difficult analytical performance requirements - ie a method needs to be reas

Chemical Analysis as a Cyclic Procedure (A Chain is Only as Strong as its Weakest Link)only as strong as its weakest link In general, the weakest links in an analytical procedure are not the ones usually being recognized as parts of a chemical analysis, such as chromatographic separation or spectrometric detection, but rather the preceding steps: the selection of the object(s) to be s
