Factors affecting the accumulation of Dimethoate in soil

Autor: D. E. Cotton, J. V. Wheelock, I. O. D. El Beit

Publikováno v: International Journal of Environmental Studies. 11:187-196

The effects of frequency of application, initial soil moisture content, rate of water application and soil organic matter content on the accumulation of dimethoate in different soils have been studied in the laboratory. It was found that: residual ac

Association of bovine αs1- and β-casein using the fluorescent properties of 1,8-anilinonaphthalene sulphonate

Autor: L. K. Creamer, J. V. Wheelock

Publikováno v: Journal of Dairy Research. 42:381-389

SummaryThe effects of NaCl, CaCl2and temperature on the emitted fluorescence of anilinonaphthalene sulphonate (ANS) in solutions of αs1- and β-casein indicated that the ANS was associated with the protein. Increased aggregation of the protein was r

The effect of reduction and alkylation on the primary phase of rennin action on unheated and heated milk

Autor: J. V. Wheelock, G. A. Wilson, A. Kirk

Publikováno v: Journal of Dairy Research. 41:37-44

SummaryThe effects of cystine-reducing and sulphydryl-alkylating agents on the extent of the primary phase of rennin action on unheated and heated milk samples were studied. Alkylating agents alone had a negligible effect, but heated samples, reduced

Pesticide‐microbial interaction in the soil

Autor: J. V. Wheelock, D. E. Cotton, I. O. D. El Beit

Publikováno v: International Journal of Environmental Studies. 16:171-179

Soils collected from the Gezira irrigation scheme in Sudan were incubated with five pesticides (pyrolan, α‐and β‐endosulphan, γ‐HCH and dieldrin), using three independent methods (incubation of microbial culture with soil and leachates, with

Separation of the glycopeptides released by the action of rennin on whole milk

Autor: G. Sinkinson, G. Simpson, J. V. Wheelock

Publikováno v: Journal of Dairy Research. 42:101-109

SummaryA comparison has been made of a number of different elution conditions for the separation by ion-exchange chromatography of the glycopeptides released by the action of rennin on whole milk. It was found that the most satisfactory separation wa

Factors influencing the degradation of dimethoate in soils and solutions

Autor: D. E. Cotton, I. O. D. El Beit, J. V. Wheelock

Publikováno v: International Journal of Environmental Studies. 11:253-260

It was found that pH, temperature and the type of medium are important factors affecting the stability of dimethoate in soils and solutions. Evaporation is a minor factor in determining the loss of dimethoate from water. Within the pH range of 7–11

Factors affecting the fate of dimethoate in soils

Autor: D. E. Cotton, I. O. D. El Beit, J. V. Wheelock

Publikováno v: International Journal of Environmental Studies. 11:113-124

For a given application of dimethoate, the loss by leaching increased with soil type in the following order: clay clay loam > sand > S.C.L. > loam. However, the loss due to evaporation alone was in the order; sand > S.C.L. > clay loam > loam. Biologi

Factors involved in the dynamics of pesticides in soils: the effect of pesticide concentration on leachability and adsorption

Autor: J. V. Wheelock, D. E. Cotton, I. O. D. El Beit

Publikováno v: International Journal of Environmental Studies. 16:181-187

The effect of concentration on leachability and adsorption of γ‐HCH, dieldrin, endosulphan and pyrolan was studied in a sandy clay loam from Northern England (Yorkshire region), under laboratory and greenhouse conditions. Concentration did not aff
