Exposure of Chlorpyrifos Coated Long-Lasting Insecticidal Bed Net into the Artificial Saliva and Determination of Residual Concentration Using LC-MS/MS Anbazhagan Vijayakumar, Atmakuru Ramesh Applied Ecology and Environmental Sciences. 2022 10 (4). doi: 10.12691/aees-10-4-9 Keywords: LC-MS/MS, leaching, LLIN, pesticide, residue, household, malaria, MRM , risk of LLIN Context: Malaria is one among the major public health problems with an estimated million cases worldwide every year. WHO recommends the use of insecticide-treated nets, particularly long-lasting insecticidal nets (LLIN), to reduce malarial deaths [1]. The treated bed nets have been factory incorporated and coated with long-lasting insecticidal Nets (LLINs) to protect people from malaria and also reduce incidence of malaria in a population [2]. Pyrethroid insecticides have been extensively used for the treatment of nets to protect against malaria and other vector-borne diseases. The new LLIN products are under the development and its requiring assessment of risks to humans. Which have been shown to be cost-effective to reduce malaria for children (< 5 years of age). Striving plans for their extensive use in worldwide for self-protection from mosquitoes [3], prevention from malaria and another severe disease. The health risks from the LLINs have not been sufficiently investigated and reported in the peer-reviewed scientific literature [4,5]. Here, we use a probabilistic risk assessment approach to estimate the risks when a child chewing the pesticide treated nets while sleeping under the bed nets [6]. The experiment was conducted in artificial biological fluid to determine the amount of potential active to be leaching into the biological fluid which is artificial saliva during overnight contact. The concentration of active ingredient content release proportion from the long-lasting insecticidal net into the artificial saliva was determined by using LC-MS/MS [7,8]. During the leaching experiment at predetermined intervals at 0.5, 2, 4, 8, 12, 16, and 24 hours after immersing in artificial saliva at 36±2°C. Abstract Full Text (PDF) [Epub] Full Text (HTML)

Determination of Insecticide Residues in the Air at the Breathing Zone While Exposure the Long Lasting Insecticidal Net Using Gas Chromatography with Mass Spectrometry - (GC-MS/MS) Anbazhagan Vijayakumar, Atmakuru Ramesh Applied Ecology and Environmental Sciences. 2022 10 (6). doi: 10.12691/aees-10-6-1 Keywords: breathing zone, air concentration, LLIN, pesticide, residue, household, malaria, MRM , risk of LLIN, GC-MS, Deltamethrin Context: Long-lasting insecticidal nets (LLIN) are highly effective tools for preventing malaria infection and reducing associated morbidity and mortality [1]. Vector management chiefly through the usage of insecticide inside recurring spraying (IRS) as well as durable insecticidal nets (LLINs). The concept of utilizing insecticide-treated bed nets came during World War II, when Germans, Russian, and US armies began dealing with their combat uniforms of theirs as well as bed nets to safeguard them against vector-borne problems, primarily malaria as well as leishmaniasis [2]. There are many kinds of nets accessible. They differ by size, material, or therapy. The majority of nets are produced from polyester but nets can also be obtainable in cotton, polyethylene, or maybe polypropylene [3,4]. These insecticides are proven to pose really low health consequences to other mammals and humans, but are extremely poisonous to insects and knock them down, while at really low doses [5]. Mosquitoes drawn towards the LLIN due to the attraction of host (Personnel sleeping down the net), on landing the Insecticide present on the nets knockdown and kill the mosquitoes [6]. The health consequences from the LLINs themselves haven't been properly investigated as well as reported in the peer-reviewed scientific literature. A scientifically rigorous, objective, and also a transparent examination of the risks related to LLINs is necessary to give risk-benefit considerations from this promising technological innovation. Pyrethroids present in the air even they are semi-volatile organic compounds. The pesticide inhalation exposures from the bed net were estimated based on indoor Bomann study [7] The level of breathing zone pesticide was estimated this experiment and determined the concentration of active ingredient present in the breathing zone while using the Deltamethrin 1.52 g/kg coated onto filaments Polyester Long Lasting insecticidal Net. The possible daily systemic dose likely to prevail at the breathing zone due to the inhalation of insecticide while sleeping under the treated net is determined. The experiment was conducted in a chamber of size 10 ft x 10 ft x 10 ft (L x B x H). The net sample was fixed in the room following the routine usage pattern. The indoor air was sampled at an interval of 0 hr (5 minutes after experiment initiation), 2 hr, 4 hr, 9 hr, 10 hr, 11 hr, 12 hr and 14 hr. The air sampling was done at a constant flow rate of 5 L/min for 5 minutes (25 L of air). At each sampling occasion the air was suctioned through silica cartridges from four pre-determined locations of the room using suction pump assembly having air rotameters. The experiment was repeated for three days. The residue of Deltamethrin in air was determined for a period of 14 hours in static conditions (no air exchange in the experimental chamber) and dynamic condition at an air exchange rate 0.5 AER/h.

Chemical Profile, Antioxidant and Antimicrobial Activity of Red Grapefruit (Citrus paradisi Macf.) from Serbian Market Vojkan M. Miljković, Ivana Nešić, Milan Z. Momčilović, Jelena MRM ošanin, Ivana Gajić, Jelena Zvezdanović, Milena Miljković Journal of Food and Nutrition Research. 2023 11 (12). doi: 10.12691/jfnr-11-12-4 Keywords: red grapefruit, lycopene, β-carotene, antimicrobial activity Context: The aim of this work is to give in one place as much information as possible on red grapefruit (Citrus paradisi Macf.) present on Serbian market. In order to provide chemical composition UHPLC-ESI-MS was employed for both polar and non-polar red grapefruit extracts obtained with solvent mixture consisting of hexane, acetone, and ethanol in volumes ratio 2:1:1, respectively and 0.05% (w/v) butylated hydroxytoluene. In addition, total content of lycopene, β-carotene, total polyphenols, and flavonoids content were determined by the means of UV-Vis spectrophotometry. The antioxidant activity of the samples was tested by applying four different methods: ABTS, DPPH, FRAP, and CUPRAC. In the chemical profile of the red grapefruit, 11 compounds of interests were identified by UHPLC method and they all were correlated to antioxidant and antimicrobial activity. The antimicrobial activity was tested against gram-positive (Staphylococcus aureus, Enterococcus faecalis, Bacillus cereus) and gram-negative (Escherichia coli, Salmonella enteritidis, Enteroabacter aerogenes, Pseudomonas aeruginosa) bacteria and yeast Candida albicans. The obtained results are as follows: lycopene, β-carotene, total polyphenols, and flavonoids content 34.2 mg/kg fruit weight, 18.6 mg/kg fruit weight, 298 mgGAE/kg fruit weight, 216.4 mgCE/kg 216.4, respectively; antioxidant activity by: ABTS 1.8 mmol of TE/kg of sample, DPPH 0.72 mmol of TE/kg of sample, FRAP 9.7 µmol of Fe2+ equivalents/kg of the sample, CUPRAC 4.66 mmol of TE/kg of sample; and they are the basis for explanation of antimicrobial activity obtained in this work. Results obtained in this study are recommending red grapefruit in everyday diet as valuable source of health beneficial bioactive compounds. Abstract Full Text (PDF) [Epub] Full Text (HTML)
