Organic Matter Reactions Involving Herbicides in Soil

Journal of Environmental Quality, 1972
AbstractDocumentary evidence is presented in support of the view that organic matter plays a major role in the adsorption of herbicides in soil, and that organic matter content is usually the soil factor most directly related to herbicidal behavior. Major attention is given to the nature and origin of humic and fulvic acids, with special emphasis being

Surface Ionization Organic Mass Spectrometry ofs-Triazine Herbicides

Journal of Mass Spectrometry, 1997
Surface ionization organic mass spectrometry (SIOMS) was applied to some s-triazine herbicides (simazine, atrazine, simetryne, ametryne and prometryne) by using quadrupole mass spectrometry in which the thermal ion source has a rhenium oxide emitter.

Ecotoxicological assessment of glyphosate-based herbicides: Effects on different organisms

Environmental Toxicology and Chemistry, 2016
Abstract   Glyphosate-based herbicides are the most commonly used worldwide because they are effective and relatively nontoxic to nontarget species. Unlimited and uncontrolled use of such pesticides can have serious consequences for human health and ecological balance.

Effects of herbicides on target and nontarget organisms

2011
Pesticides have significant environmental and public health impact. This study examined the target and nontarget effects of herbicide Sekator OD 375 (amidosulfuron and iodosulfuron) to target weed species Chenopodium album L., to two nontarget plant species – barley Hordeum vulgare L.; duckweed Lemna minor L.

Role of Humified Organic Matter in Herbicide Adsorption

Weed Technology, 1989
Organic matter is the soil constituent most often associated with herbicide adsorption. Structural diversity makes humified organic material an ideal substrate for the adsorption of many pesticides, but variability in composition and distribution in situ complicates interpretation of its quantitative effect on adsorption.

HERBICIDES THE RELATIVE TOXICITY OF NITROPHENOLS TO VARIOUS ORGANISMS

Annals of Applied Biology, 1952
The effect of increasing degrees of nitration on the toxicity of phenols was assessed by measuring the toxicity of phenol, o‐ and p‐nitro phenols and 2:4‐dinitro phenol with several different test organisms. Toxicity levels were determined by the concentration required in each case to bring about the following responses: (i) to halve the rate of radial

Organic Substrates and Microbial Conversion of Herbicides in Soil

1992
ABSTRACT Kunc, F., 1991. Organic substrates and microbial conversion of herbicides in soil. Presence of organic compounds in soil is one of the main factors that determine the activity of microorganisms including their capability of conversion of xenobiotics.
