Photolytic degradation of decabromodiphenyl ethane (DBDPE).
The photolytic degradation of decabromodiphenyl ethane (DBDPE), an alternative flame retardant to decabromodiphenyl ether, was investigated in a variety of matrixes (n-hexane, tetrahydrofuran, methanol/water, humic acid/water, and silica gel) by irradiation under ultraviolet light and in n-hexane under natural light. Photolytic degradation of DBDPE occurs in all the matrixes investigated within...
متن کاملImpacts of seed priming with salicylic acid and sodium hydrosulfide on possible metabolic pathway of two amino acids in maize plant under lead stress
Heavy metals pollution is one of the key environmental problems. In this research, the effect of seed priming with salicylic acid and sodium hydrosulfide was investigated on methionine and arginine amino acids contents and some compounds derived from their metabolism as well as ZmACS6 and ZmSAMD transcripts levels in maize plants under lead stress. For this purpose, maize seeds were soaked in s...
متن کاملPhotolytic and enzymatic transformations of pteroylglutamic acid.
Bloom et al. (1) found that ultraviolet light converted pteroylglutamic acid (PGA) which is not fluorescent into a fluorescent material. Stokstad, Fordham, and de Grunigen (2) observed that sunlight caused the liberation of a diazotizable amine, indicating that cleavage had occurred between the pterine and the p-aminobenzoylglutamic acid components. As part of a search for a sensitive analytica...
متن کاملconjugated linoleic acids, amino acid profile and other characteristics of meat produced under identical condition from two iranian fat tailed breeds of lamb
گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
Photolytic and Microbial Degradation of 3,5,6-trichloro-2-pyridinol
The photolytic and microbial degradation of 3,5,6-trichloro-2-pyridinol (TCP), a metabolite of the insecticide chlorpyrifos and the herbicide triclopyr, has been investigated. TCP (80 mg/L) was decomposed to nondetectable levels within 2 h of ultraviolet irradiation. Release of CO2 and chloride ion was observed; however, approximately 60% of the initial radioactivity remained in the solution. D...
