Summary of Toxicity Studies with Fenoxaprop-ethyl

Toxicity Studies of Ethyl Maltol and Iron Complexes in Mice

Ethyl maltol and iron complexes are products of ethyl maltol and the iron found in the cooking pots used to prepare the Chinese dish, hot-pot. Because their safety is undocumented, the toxicity study of ethyl maltol and iron complexes was conducted in male and female Kunming (KM) mice. The animal study was designed based on the preliminary study conducted to determine the median lethal dose (LD...

Summary of dose-response modeling for developmental toxicity studies.

Developmental toxicity studies are an important area in the field of toxicology. Endpoints measured on fetuses include weight and indicators of death and malformation. Binary indicator measures are typically summed over the litter and a discrete distribution is assumed to model the number of adversely affected fetuses. Additionally, there is noticeable variation in the litter responses within d...

Flow Injection Spectrophotometric Determination of Fenoxaprop-p-ethyl Herbicide in Different Grain Samples after Derivatization

Propomos um método espectrofotométrico para a determinação do herbicida fenoxaprop-p-etil, usando injeção em fluxo.O fenoxaprop-p-etil foi convertido num ácido hidroxamico, na presença de hidroxilamina dihidrocloridrica em meio alcalino. O ácido hidroxâmico obtido reagiu com ferro(III) formando um complexo hidroxamato de ferro(III), vermelho. A absorbância do complexo foi medida a 500 nm em sis...

Environmental Fate of Chiral Herbicide Fenoxaprop-ethyl in Water-Sediment Microcosms

The environmental fate of the herbicide fenoxaprop-ethyl (FE) in water, sediment and water-sediment microcosm was studied and degradation products fenoxaprop (FA), ethyl-2-(4-hydroxyphenoxy)propanoate (EHPP), 2-(4-hydroxyphenoxy)propanoic acid (HPPA) and 6-chloro-2,3-dihydrobenzoxazol-2-one (CDHB) were monitored. FE, FA, EHPP and HPPA were chiral and the environmental behavior was investigated ...
