A Rapid and Simple Bioassay Method for Herbicide Detection
Chlamydomonas reinhardtii, a unicellular green alga, has been used in bioassay detection of a variety of toxic compounds such as pesticides and toxic metals, but mainly using liquid culture systems. In this study, an algal lawn-agar system for semi-quantitative bioassay of herbicidal activities has been developed. Sixteen different herbicides belonging to 11 different categories were applied to...
متن کاملChlorophyll Fluorescence: A Novel Method to Screen for Herbicide Resistance
The susceptibility to Terbacil of six randomly selected strawberry cultivars (‘Aromas’, ‘Chambly’, ‘Harmonie’, ‘Kent’, ‘La Clé des Champs’ and ‘Seascape’) was analysed using chlorophyll florescence (CF) in comparison with visual observation, in an attempt to develop a method for use in a breeding programme to select herbicide-resistant strawberry lines. Terbacil was applied at one of five rates...
متن کاملA Rapid Method for Detecting Bacteria in Drinking Water
A rapid determination of the total bacterial count in drinking water is important to the operators of treatment plants and distribution systems. It will allow corrective measures in real-time, such as increasing the disinfectant dose or removing water that has high bacterial numbers. The present heterotrophic plate count (HPC) analysis takes seven days and is not useful for operational interven...
متن کاملA method for detecting water in organic solvents.
The potent dehydrating ability of difluoro(aryl)-lambda (3)-iodanes is exploited to develop a convenient (19)F-NMR-based aquametry method that is more sensitive than coulometric Karl Fischer titration. The key difluoro(aryl)-lambda (3)-iodane reagents are synthesized readily from commercially available and inexpensive precursors.
متن کاملFinding minimal herbicide concentrations in ground water? Try looking for their degradates.
Extensive research has been conducted regarding the occurrence of herbicides in the hydrologic system, their fate, and their effects on human health and the environment. Few studies, however, have considered herbicide transformation products (degradates). In this study of Iowa ground water, herbicide degradates were frequently detected. In fact, herbicide degradates were eight of the 10 most fr...
