Ultrasensitive and specific fluorescent probe towards sulfites to monitor its residue in the traditional herbs.

As one of the traditional pretreatments for many Chinese herbal medicines, Sulfur Fumigation might remain residual sulfites which would endanger human health when overdosage. It should be invaluable to monitor their residual content in food or medicines. Abundant novel fluorescent probes for sulfur dioxide were designed, constructed and evaluated with excellent sensitivity, but lack in specificity. One of numerous potential candidates based on semi-cyanine fluorophores, N-3-I was synthesized, characterized and identified as the satisfactory candidates for the rapid detection of sulfites (<1 mi…

Tolerance of fifteen hydroponic ornamental plant species to formaldehyde stress.

An indoor formaldehyde enriched environment was created by an automatic fumigation system with timing and concentration control. Selected hydroponic plant species were exposed in formaldehyde concentrations of 10 mg m-3, 50 mg m-3 and 100 mg m-3 respectively for 6 days with 10-h-treatment each day. Changes in morphological characteristics including leaf damage rate, leaf damage time and survival rate were monitored to evaluate morphological resistance to formaldehyde. Assessed physiological parameters were leaf chlorophyll content (Chl), leaf malondialdehyde content (MDA), activity of leaf for…

[Potential of purifying SO2 of main tree species and their planting quota in Shenyang area].

The total potential of purifying SO2 of main tree species was studied by using the combination of field measurement and fumigation experiment in this paper. The integrated value of purifying SO2 including total bimass, absorption intensity of SO2, and absorption-transformation periods of sulfur by trees was 4.39 x 10(6) kg, which was accounted for 3.66% of total sulfur released per year in Shenyang. It indicated that the maximum daily potential of purifying SO2 of trees might be 12.19 kg.km-2. Supposed that the average annual absorption capacity for sulfur of trees in Shenyang was 0.70 kg per …

Involvement of energy metabolism to chilling tolerance induced by hydrogen sulfide in cold-stored banana fruit.

In this study, the effect of hydrogen sulfide (H2S) on energy metabolism in postharvest banana fruit under chilling stress was investigated. Banana fruit, fumigated with optimal concentration (0.5mM) of aqueous sodium hydrosulfide (NaHS) solution for 24h, were initially stored at 7°C for 14d and 20°C for another 6d. H2S treated banana fruit showed both higher value of firmness and Hue angle, as well as lower value of electrolyte leakage, malondialdehyde (MDA) content and ethylene production. These indicated slower development of chilling injury compared with the control. Decrease in adenosine

Hypothyroidism and pesticide use among male private pesticide applicators in the agricultural health study.

OBJECTIVE: Evaluate the association between thyroid disease and use of insecticides, herbicides, and fumigants/fungicides in male applicators in the Agricultural Health Study. METHODS: We examined the association between use of 50 specific pesticides and self-reported hypothyroidism, hyperthyroidism, and "other" thyroid disease among 22,246 male pesticide applicators. RESULTS: There was increased odds of hypothyroidism with ever use of the herbicides 2,4-D (2,4-dichlorophenoxyacetic acid), 2,4,5-T (2,4,5-trichlorophenoxyacetic acid), 2,4,5-TP (2,4,5-trichlorophenoxy-propionic acid), alachlor

Sensitivity of Aedes aegypti adults (Diptera: Culicidae) to the vapors of Eucalyptus essential oils.

Vapors of essential oils extracted from various species of Eucalyptus (E. gunnii, E. tereticornis, E. grandis, E. camaldulensis, E. dunnii, E. cinerea, E. saligna, E. sideroxylon, E. globulus ssp. globulus, E. globulus ssp. maidenii, E. viminalis and the hybrids E. grandisxE. tereticornis and E. grandisxE. camaldulensis) and their major components were found to be toxic to Aedes aegypti adults, the yellow fever mosquito. An aliquot of each oil was placed in a cylindrical test chamber and the number of knocked-down mosquitoes was recorded as function of time. Knockdown time 50% was then calcula

Gliomas and farm pesticide exposure in men: the upper midwest health study.

The National Institute for Occupational Safety and Health evaluated farm pesticide exposure and glioma risk in a study that included 457 glioma cases and 648 population-based controls, all adult men (18-80 yr old) and nonmetropolitan residents of Iowa, Michigan, Minnesota, and Wisconsin. Multiple logistic regressions were used to control for farm residence, age, age group, education, and exposure to other pesticides. No associations were found between glioma and 12 specific pesticides. We estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) and found reduced glioma risk for

Survival after aluminum phosphide poisoning with cardiotoxicity: a case report.

INTRODUCTION: Aluminum phosphide is a cheap and commonly used rodenticide that is also an effective solid fumigant and frequently used for grain preservation. The pill contains around 44% inert elements (ammonium carbonate) to avoid disintegration of the tablet, while the rest (about 56%) is aluminum phosphide. Because it is freely available on the market, it is one of the commonly used agents for self-poisoning in different parts of the developing world. Early signs of toxicity are manifested by shock and circulatory failure. Until now, no specific antidote is available. Aggressive supportive

Associations between pesticide use and respiratory symptoms: A cross-sectional study in Southern Ghana.

BACKGROUND: Indiscriminate use of pesticides is a common practice amongst farmers in Low and Middle Income Countries (LMIC) across the globe. However, there is little evidence defining whether pesticide use is associated with respiratory symptoms. OBJECTIVES: This cross-sectional study was conducted with 300 vegetable farmers in southern Ghana (Akumadan). Data on pesticide use was collected with an interviewed-administered questionnaire. The concentration of seven organochlorine pesticides and 3 pyrethroid pesticides was assayed in urine collected from a sub-population of 100 vegetable farmer

Global ethylene oxide uses in foods and considerations for food safety.

Ethylene oxide (EtO) is a sterilant widely used for medical devices, but its use is controversial due to its carcinogenicity. In some countries, EtO is also used to fumigate food to eliminate foodborne pathogens, though this practice is banned in others. National regulations on EtO use in food vary widely; exporting countries prioritize trade facilitation and prevention of foodborne illness, while importing countries emphasize maintaining food safety and promoting domestic public health. These divergent public health priorities present challenges to establishing universal maximum residue limit

Diallyl Trisulfide, a Biologically Active Component of Garlic Essential Oil, Decreases Male Fertility in Sitotroga cerealella by Impairing Dimorphic Spermatogenesis, Sperm Motility and Lipid Homeostasis.

Diallyl trisulfide (DAT) is a biologically active component of garlic essential oil and exhibits multi-targeted activity against many organisms. The current study tested the capacity of DAT to decrease the male fertility of Sitotroga cerealella. The effects on testis morphology, sperm number, motility, and lipid homeostasis were observed in adult males fumigated with DAT at a dose of 0.01 μL/L in air. The results indicated that the DAT significantly decreased the dimorphic sperm number. Meanwhile, the ultrastructural analysis of the sperm showed that the DAT caused malformed and aberrant struc
