1) During 1994-1995, the toxic effect of parathion on two marine microalgae was analyzed with acute toxicity and biochemistry methods.

2) Degradation characteristics of parathion, parathion methyl and fenitrothion by a enzyme, extracted from the isolated strain YF11, was determined.

3) The biodegradation of parathion methyl by Plesiomonas sp. (DLL 1)in soils and the influence factors were studied both in laboratory and field test.

4) The effect of parathion on the synthesis of protein and nucleic acid in Phaeodactylum tricornutum was studied with isotope tracing methods.

5) Methyl parathion hydrolase (MPH) is a novel member of organophosphorus hydrolase.

6) The mechanism and kinetics of parathion degradation was investigated under high frequency ultrasonic irradiation in aqueous solution.

7) Omethoate,[http://sentencedict.com/parathion.html] Cypermethrin and parathion additive does not affect its basic effect.

8) The inhibition of parathion, phoxim , methomyl, arprocarb, imidacloprid andavermectins to tyrosinase is not obvious.

9) A novel electrochemical sensor for the detection of parathion based on molecularly imprinted polymer of self-assembled o-aminothiophenol onto gold electrode was constructed.

10) Objective To screen parathion residues in importing and exporting plants through indirect competitive ELISA method.

11) Methyl parathion hydrolase (MPH) was a novel member of phosphotriesterase.

12) Chlorpyrifos was one kind of organophosphorus pesticides with higher efficacy and could substitute highly poisonous metham-sodium and parathion .

13) A method was developed for simultaneous determination of methyl-parathion and parathion residues in vegetables by reversed-phase high performance liquid chromatography.

14) Role in the nervous system of pests, such as DDT, parathion , carbofuran, esters, such as pyrethrum.

15) A method was developed to separate and determine paraoxon, methyl parathion, ethyl parathion and fenitrothion by micellar electrokinetic capillary electrophoresis with electrochemical detection.

16) Organochrorinated pesticides residues(666, DDT) maintained downtrend and organophosphorus pesticides residues met the national associated criteria except methyl parathion in cereals.

17) A method of micellar electrokinetic capillary chromatography (MECC) with usual injection was developed for the determination of Methyl parathion.

18) We found that purified MPH have a 20-fold higher hydrolytic efficiency to methyl parathion than to parathion.

19) The conclusion can be drawn that Chinese cabbage applied methyl parathion can not be consumed in seven days.
