2007 journal article

Inhibition of fipronil and nonane metabolism in human liver microsomes and human cytochrome P450 isoforms by chlorpyrifos

JOURNAL OF BIOCHEMICAL AND MOLECULAR TOXICOLOGY, 21(2), 76–80.

By: H. Joo n, K. Choi n, R. Rose n & E. Hodgson n

author keywords: fipronil; nonane; human liver microsomes; cytochrome P450; CYP2B6; CYP3A4
MeSH headings : Alkanes / pharmacology; Aryl Hydrocarbon Hydroxylases / antagonists & inhibitors; Aryl Hydrocarbon Hydroxylases / metabolism; Chlorpyrifos / pharmacology; Cytochrome P-450 CYP2B6; Cytochrome P-450 CYP3A; Cytochrome P-450 Enzyme Inhibitors; Cytochrome P-450 Enzyme System / metabolism; Enzyme Activation / drug effects; Female; Humans; Insecticides / pharmacology; Isoenzymes / antagonists & inhibitors; Isoenzymes / metabolism; Male; Microsomes, Liver / enzymology; Oxidoreductases, N-Demethylating / antagonists & inhibitors; Oxidoreductases, N-Demethylating / metabolism; Pyrazoles / pharmacology
TL;DR: In both co‐ and preincubation experiments, CPS significantly inhibited the metabolism of fipronil or nonane by HLM although CPS inhibited the metabolization of fIPronil more effectively than that of nonane. (via Semantic Scholar)

2007 journal article

Summer cover crops reduce atrazine leaching to shallow groundwater in southern Florida

JOURNAL OF ENVIRONMENTAL QUALITY, 36(5), 1301–1309.

By: T. Potter*, D. Bosch*, H. Joo n, B. Schaffer * & R. Munoz-Carpena*

MeSH headings : Atrazine / analysis; Atrazine / metabolism; Biodegradation, Environmental; Crotalaria; Environmental Monitoring; Florida; Herbicides / analysis; Herbicides / metabolism; Rain; Seasons; Soil / analysis; Water Pollutants, Chemical / analysis; Water Pollutants, Chemical / metabolism; Zea mays / growth & development
TL;DR: Groundwater data and laboratory study findings demonstrated a relatively small although potentially significant risk for leaching of atrazine and its dealkylated degradates to groundwater and that the use of a cover crop like Sunn Hemp during summer months may be an effective mitigation measure.

2006 journal article

Metabolism of chlorpyrifos and chlorpyrifos oxon by human hepatocytes

Journal of Biochemical and Molecular Toxicology, 20(6), 279–291.

By: K. Choi n, H. Joo n, R. Rose n & E. Hodgson

MeSH headings : Adult; Biotransformation; Chlorpyrifos / analogs & derivatives; Chlorpyrifos / analysis; Chlorpyrifos / chemistry; Chlorpyrifos / metabolism; Chlorpyrifos / toxicity; Chromatography, High Pressure Liquid; Female; Hepatocytes / drug effects; Hepatocytes / metabolism; Humans; Male; Mass Spectrometry; Middle Aged; Subcellular Fractions
TL;DR: The results suggest that human liver plays an important role in detoxification, rather than activation, of CPS, and phase II‐related conjugates, including O‐ and S‐glucuronides, were identified in CPS‐treated human hepatocytes, although the O‐sulfate of TCP conjugate was found only when human liver S9 fractions were used as the enzyme source.

Accelerated soil dissipation of tebuconazole following multiple applications to peanut

JOURNAL OF ENVIRONMENTAL QUALITY, 34(4), 1205–1213.

By: T. Potter*, T. Strickland *, H. Joo n & A. Culbreath *

MeSH headings : Arachis; Environmental Monitoring; Kinetics; Soil; Soil Pollutants / analysis; Temperature; Triazoles / analysis; Triazoles / chemistry; Water
TL;DR: It is indicated that varying soil conditions (in particular, soil temperature and water content) may have an equal or greater impact on field dissipation rate than development of accelerated dissipation. (via Semantic Scholar)
