Environmental Aspects of Abamectin Use in Crop Protection
The use of any chemical as a pesticide results in the exposure of the environment to the chemical. The extent of this exposure depends on the way the chemical is applied—pattern, rate, andExpand
Environmental effects of the usage of avermectins in livestock.
As abamectin and ivermectin undergo rapid degradation in light and soil, and bind tightly to soil and sediment, they will not accumulate and will not undergo translocation in the environment, minimizing any environmental impact on non-target organisms resulting from their use. Expand
Environmental effects of the anti-sea lice (Copepoda: Caligidae) therapeutant emamectin benzoate under commercial use conditions in the marine environment
Macrobenthic faunal analysis indicated that there was no evidence that the occurrence of emamectin benzoate, or its desmethylamino metabolite, in sediments around fish farm cages after treatment had any toxic impacts on organisms in either water column or sediments. Expand
A uniform procedure to estimate the predicted environmental concentration of the residues of veterinary medicines in soil
New guidelines to assess the environmental risk of veterinary medicines (VMs) have been proposed in the European Union. As in any risk assessment, exposure is a factor of critical importance. TheExpand
Binding of benzo[a]pyrene 7,8-diol-9,10-epoxides to DNA, RNA, and protein of mouse skin occurs with high stereoselectivity.
Polymer adducts from diastereomeric diol epoxides were formed stereospecifically from their corresponding 7,8-dihydrodiols, and binding occurs preferentially at the 2-amino group of guanine in cellular RNA and DNA in vivo. Expand
Tumorigenicity of nitrated derivatives of pyrene, benz[a]anthracene, chrysene and benzo[a]pyrene in the newborn mouse assay.
Eight nitropolycyclic aromatic hydrocarbons, including 1- and 4-nitropyrene, 1,3-, 1,6- and 1,8-dinitropyrene and 6-nitrochrysene, and their parent PAHs were tested fro tumorigenicity in the newborn mouse model by i.p. administration at 1, 8, and 15 days after birth. Expand
Tumorigenicity of the optical enantiomers of the diastereomeric benzo[a]pyrene 7,8-diol-9,10-epoxides in newborn mice: exceptional activity of
Differences in the carcinogenic activities of optically active isomers of a polycyclic hydrocarbon diol epoxide are demonstrated by testing the tumorigenicities and activity of benzo[a]pyrene and the other three optically pure isomers. Expand
Mutagenicity of benzylic acetates, sulfates and bromides of polycyclic aromatic hydrocarbons.
Results demonstrate that meso-anthracenic benzylic acetates, sulfates and bromides are mutagenic, whereas benzyLic acetate esters attached to other carbon atoms are inactive. Expand
Photodegradation of avermectin B1a thin films on glass
Photodegradation of avermectin B 1a thin films under artificial light (above 260 nm) for short periods of time (greater than 60% of parent compound remaining) resulted in the formation of at least 10Expand
