V-type nerve agents, known as VX, are organophosphate (OP) compounds, and show extremely toxic effects on human and animals by causing cholinergic overstimulation of synapses. The bacterial organophosphorus hydrolase (OPH) has attracted much attention for detoxifying V-type agents through hydrolysis

The chemical fate of organophosphorus pesticides (OPs) has been proven to depend strongly on the chemistry of their aquatic environment. In particular, metal ions (and metal oxide surfaces) have been known to play an important role in the hydrolytic fate

Butyrylcholinesterase-encapsulating bioadhesive liposomes are investigated as prophylactic scavengers of organophosphates for local administration to skin, eyes, airways, and lungs-gates through which organophosphates penetrate living systems. The systems were optimized with respect to: encapsulation efficiency; type of bioadhesive ligand bound to

The psocid, Liposcelis paeta Pearman, is an increasingly important polyphagous pest of stored products worldwide. Intensive use of organophosphorous insecticides for pest control has facilitated resistance development in psocids in China. Three insecticide-resistant field populations of L. paeta were collected
