The dehydration of glycerol to hydroxyacetone was studied over copper-based catalysts using magnesium oxide (hydroxide) fluoride with various F/Mg ratio as support of copper. After calcination at 350 °C, the incorporation of copper, mainly at + II oxidation state, into the support lattice was o...

Electric field effect was investigated on 1-hydroxyacetone (HA) as a model compound of the acyclic form of saccharide moiety employing infrared electroabsorption spectroscopy. We examined the structural tautomerization of the hydroxyacetyl group of HA in detail by monitoring change in IR absorpt...

This study is the first to report sound production in Japanese medaka (Oryzias latipes). Sound production was affected by exposure to the carbamate insecticide (aldicarb) and heavy-metal compound (copper sulfate). Medaka were exposed at four concentrations (aldicarb: 0, 0.25, 0.5, and 1 mg L−1; ...

Management of pesticide standard values (PSVs) in different human exposure pathways is critical since pesticides may significantly impact human health from the exposure. Aldicarb, Atrazine, Diuron, Glyphosate, and MCPA are the five most widely used pesticides in the world. Many international jur...

Surfactant enhanced desorption of aldicarb from spiked soil was investigated in this paper. Anionic (sodium dodecyl benzene sulphonate, SDBS), cationic (hexadecyl trimethyl ammonium bromide, HTAB) and nonionic (octyl polyethylene glycol phenyl ether, OP) surfactants were tested to determine thei...

An analytical method for the determination of aldicarb, and its two major metabolites, aldicarb sulfoxide and aldicarb sulfone in fruits and vegetables is described. Briefly the method consisted of the use of a methanolic extraction, liquid–liquid extraction followed by solid-phase extraction c...

The carbamate aldicarb (Temik®) is a highly toxic (LD50 = 0.9 mg/kg oral in rats) insecticide often used in agriculture.The authors present a fatal intoxication case with aldicarb, in a 24-year-old male, under police custody in the island of S. Tome and Prince (STP), in Africa. He was found 3 h ...

The intentional and accidental poisoning of animals and people is a threat to public health and safety worldwide. Necropsies and histopathological examinations of 26 cats and 10 dogs poisoned by the carbamates aldicarb and carbofuran, confirmed by thin layer chromatography (TLC) and high perform...

Aldicarb (CAS 116-06-3) is an N-methyl carbamate insecticide that rapidly and reversibly inhibits acetylcholinesterase. The nervous system is the most sensitive target, and there is little evidence of other forms of toxicity. Aldicarb is highly toxic to humans and wildlife. Ground water and food...

People and animals can be unintentionally exposed to complex mixtures of hazardous chemicals that can threaten the safety of food and water supplies following natural and man-made disasters and emergencies. Our research has focused on the development of broad-acting adsorbents that will tightly ...

Rat hepatic HMGCoA reductase was found to be at least 50% inhibited 17 hr after administration of a single oral dose of 3,3,5-trimethylcyclohexanyl mandelate (cyclandelate), a vasoactive substance. This inhibition was also found in rats given the 3,3,5-trimethylcyclohexanol component but only sl...

A toxicologic and dermatologic review of linalyl formate when used a a fragrance ingredient is presented.

Organophosphorus esters (OPEs) are emerging contaminants widely applied as annexing agents in a variety of industrial products, and they are robust against conventional wastewater treatments. Ultraviolet-driven (UV) radical-based advanced oxidation processes have a potential to become cost-effec...

Organophosphate esters (OPEs) draw growing concern about characterizing the potential risk on environmental health due to its wide usage and distribution. Two typical types of organophosphate esters (OPEs): tris (2-chloroethyl) phosphate (TCEP) and tricresyl phosphate (TCP) were selected to eval...

Electrical impedance spectroscopy measurements were performed on metal–insulator–metal structures using recently developed plasma deposited thin films of linalyl acetate as the insulating layer between frequencies of 10 Hz and 100 kHz in order to better understand this material's dielectr...

A toxicologic and dermatologic review of linalyl acetate when used as a fragrance ingredient is presented.

Bergamot (Citrus bergamia, Risso et Poiteau) essential oil (BEO) is a widely used plant extract showing anxiolytic, analgesic and neuroprotective effects in rodents; also, BEO activates multiple death pathways in cancer cells. Despite detailed knowledge of its chemical composition, the constitue...

Thin films of plasma polymerised linalyl acetate (PLA) were fabricated and their electrical properties investigated. The high frequency dielectric constant was determined using the split post dielectric resonator (SPDR) technique at frequencies of 10 GHz and 20 GHz and compared with the low freq...

Present letter is aimed at clarifying some critical points highlighted by Api et al. as major limits for the reliability of our data on the genotoxicity of linalyl acetate. Particularly, we explained the choice of the study design and methodology applied for carrying out the Ames test and the mi...

In this paper experimental equilibrium data of the system CO2 – bergamot essential oil are reported at 323 K and 343 K, in the pressure range 7.8–13.1 MPa. Furthermore equilibrium data for the subsystem CO2 – linalyl acetate at 323 K are reported in the pressure range 7.0–10.3 MPa. The equil...
