Paraquat (known in chemistry as 1,1'-dimethyl-4,4'-bipyridinium dichloride) is a herbicide that has been in the international market since 1958.
Paraquat (1,1-dimethyl-4,4-bipyridininum ion) is one of the most common contact and non-selective herbicide for exterminating vegetative pests, is used for controlling terrestrial weeds and aquatic plants in different countries and its presence is reported in many water sources of the world (Filizadeh, 2002; Ye et al.

The second study explored again the 5' and 3' regions of SLC6A3 and determined residential exposure to agricultural maneb and
paraquat applications.
violaceum was evaluated in response to
paraquat compound by measuring the expression levels of the [beta]-galactosidase enzyme in the presence of the ONPG reagent (ortho-nitrophenyl-[beta]-D-galactopyranoside) (Sigma-Aldrich), as proposed in detail by Miller (1972).
Otro es el Convenio de Rotterdam, que regula formulaciones de plaguicidas y productos peligrosos objeto del comercio internacional, como es el caso del herbicida

Paraquat (PQ) is a nonselective, contact herbicide, used in agricultural industries.
The soil samples were systematically collected from 5 plots and
Paraquat residues concentrations were determined in dissimilar depth of soil layers.
Frank Soldner, research scientist in Jaenisch's lab and co-author of the study, said that exposing both normal and mutant neurons to pesticides, including
paraquat, maneb and rotenone, created excessive free radicals in cells with the mutation, causing damage to dopamine-containing neurons that led to cell death.
The degree of growth inhibition by the herbicides tested in vitro was in order of
paraquat and glufosinate-ammonium Greater than glyphosate Greater than metsulfuron-methyl.
