Abstract Background The present study aimed to gain a comprehensive knowledge of the presence and environmental risks pesticide repellent residues in Lake Balaton its sub-catchment area (Hungary). A unique analysis 439 active substances 17 metabolites was carried out on surface waters one effluent wastewater as only direct discharge into from June 2017 until August 2020. Altogether 203 water- 8...

In August 1989, epidemiologists from the New York State Department of Health (NYSDH) investigated five reports of generalized seizures temporally associated with topical use of N,Ndiethyl-m-toluamide (DEET). Three of the case-patients, one from New York and two from Connecticut, were reported by a pediatric neurologist who practices in both states. One case was reported initially to an entomolo...

The insect repellent DEET is one of the most common organic chemical pollutants in water a wide range countries around World. In this study, surface samples were collected seasonally, from 7 stations Seyhan River, following period between December 2016 and November 2017. concentrations River detected 18.55-334.71 ng/L. was all seven sampling detection frequency 100%. Results obtained autumn hig...

The current rise in insecticide resistance of mosquitoes to synthetic compounds that used be very effective is great concern malaria control. Several bio-compounds from plants and essential oils have insecticidal or repellent potencies. However, lack harmonization complete research on insecticides plant origin obscured the breakthrough discovering an alternative plant-based mosquito DEET-based ...

We synthesized a series of fluorinated compounds and tested them in an easy assay for their repellent activity against the ant Myrmica rubra. Depending on their chain length and pattern of fluorination these molecules are efficient repellents for this ant. Fluorinated compounds are stronger repellents than their unfluorinated analogs. 1,1,1-Trifluorotridecan-2-one (4) is an even better repellen...
