The toxicity of three organophosphorous nematicides, imicyafos, fosthiazate and cadusafos, to non-target organisms in soil was evaluated. Imicyafos and fosthiazate had no significant inhibitory effect on the growth of fungal (Fusarium oxysporum f. sp. lactucae, Rhizoctonia solani and Trichoderma viride) and bacterial (Ralstonia solanacearum and Pseudomonas fluorescens) strains in media at 12.5 ...

A colorimetric array for the chromogenic discrimination of organophosphorous derivatives in gas phase has been developed.

Background: Organophosphorus (OP) poisoning is a major public health problem in developing world. OP pesticides inhibit carboxylic esterase enzymes including plasma cholinesterase (PChE). Clinical manifestations following OP poisoning can be associated with the extent of decrease of PChE. This study was designed to investigate the relevance of PChE level to clinical manifestations in OP poisoni...

Experiments were performed investigating the potential to improve the biological activity of some phenoxy and organophosphorous compounds by using them in binary mixtures. The compounds were: 2,4-dichlorophenoxyacetic acid (1) and its sodium salt (2), dibutyl 1-butylamino-1-cyclohexanephosphonate (3) and diethyl 9-butylamino-9-fluorenephosphonate (4), all widely used as herbicides. There were t...

The organophosphorous hydrolase (PTE) from Brevundimonas diminuta is capable of degrading extremely toxic organophosphorous compounds with a high catalytic turnover and broad substrate specificity. Although the natural substrate for PTE is unknown, its loop remodeling (loop 7-2/H254R) led to the emergence of a homoserine lactonase (HSL) activity that is undetectable in PTE (kcat/km values of up...

A case of organophosphorous poisoning in a 29 year old male who developed intermediate syndrome manifested by features of respiratory depression as evidenced by marked weakness of the respiratory muscles, tachypnoea, and drop in oxygen saturation despite reversal of nicotinic and muscarinic effects of organophosphorous poisoning. The case highlights its early recognition and prompt institution ...

These CO2-philic open-chain organophosphorous chelating ligands, i.e. diethylene glycol bis (2, 4, 4-trimethyl-1-pentyl) dimethyl diphosphate (EG2TP), diethylene glycol bis (3, 5, 5-trimethyl-1-hexyl) dimethyl diphosphate (EG2TH), and diethylene glycol dioctyl dimethyl diphosphate (EG2Oct), ethylene glycol bis(2-isopropoxyethyl) dimethyl diphosphate (EG2IPE), triethylene glycol bis(2-isopropoxy...

BACKGROUND Organophosphorous pesticides are the most popular pesticides used in agriculture. As acetylcholinesterase inhibitors, organophosphorous pesticides are toxic organic chemicals. The control and detection of organophosphorous pesticide residue in food, water, and environment therefore plays a very important role in maintaining physical health. A sensitive, rapid, simple chemiluminescenc...
