The Science of the total environment, 649, 1083-1095 (2018-10-13)
The occurrence of micropollutants in the environment is a matter of high concern. Some regulations have been published in the last years and a Watch List of contaminants of emerging concern (CECs) for European Union monitoring of surface water was...
Vijayakumar Bommuraj et al.
Food additives & contaminants. Part B, Surveillance, 13(4), 233-243 (2020-05-15)
Throughout the world, more than six billion people consume milk and milk products yearly. The safety and quality of dairy milk are regularly monitored in most countries worldwide. The Israeli monitoring program of chemical residues in milk has not changed...

The Science of the total environment, 760, 143409-143409 (2020-11-22)
Neonicotinoids are the most widely used insecticides globally, but their rapid metabolism in vertebrates makes diagnosing wildlife exposure challenging. More detailed information on the pattern of imidacloprid metabolites over time could be used to better approximate the timing and level...
Laurence Lachat et al.
Journal of agricultural and food chemistry, 66(32), 8639-8646 (2018-07-22)
A very sensitive ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed and validated for the quantitation of the most common neonicotinoids (thiamethoxam, clothianidin, imidacloprid, acetamiprid, and thiacloprid) at trace levels in milk. Using fast and selective liquid-liquid extraction...
Jianbo Hou et al.
Food chemistry, 270, 204-213 (2018-09-04)
An analytical method based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the first simultaneous determination of ten neonicotinoid insecticides (pymetrozine, dinotefuran, nitenpyram, thiamethoxam, flonicamid, imidacloprid, clothianidin, imidaclothiz, acetamiprid, thiacloprid) and two metabolites (4-trifluoromethylnicotinamide and N-desmethylacetamiprid) in honey...

Food chemistry, 329, 127159-127159 (2020-06-05)
The widespread use of neonicotinoids (NEOs) and fipronils (FIPs) as insecticides in modern agriculture has been widely investigated because of their adverse effects on human health. This study aimed to develop an accurate quantitative approach to analyze NEOs and FIPs...

Talanta, 170, 392-398 (2017-05-16)
Extensive use of neonicotinoid insecticides has raised great concerns about their ecological risk. A reliable method to measure trace neonicotinoids in complicated aquatic environment is a premise for assessing their aquatic risk. To effectively remove matrix interfering substances from field...
Arthur W Schaafsma et al.
PloS one, 14(4), e0214787-e0214787 (2019-04-05)
Neonicotinoids are widely used class of insecticides. Most are seed treatments and during planting active ingredient may be abraded and lost in fugitive dust. Much of this active ingredient contaminates surface waters, exposing aquatic organism to potential ill effects. This...

Chemosphere, 248, 126040-126040 (2020-02-12)
Acetamiprid is a neonicotinoid pesticide, which is extensively used on agricultural crops, but has a high toxic effect on beneficial insects and the human body. It is exposed to sunlight irradiation on crops but also in surface waters where it...

Marine pollution bulletin, 154, 111120-111120 (2020-04-23)
This work provides the first spatial distribution report of micropollutants (MPs) in the entire Portuguese coast, comprising the ocean shore (sea water, SW) and whenever possible the nearest river discharging on it (estuarine water, EW). This surface water monitoring programme...
Changcai Wu et al.
Pest management science, 76(6), 2190-2197 (2020-01-23)
Neonicotinoid insecticides (NIs) have been recently banned in some countries because of increased pest resistance and deleterious risks to non-target organisms. Recent studies considered all parts of crops as a whole part in plant protection. However, there are few reports...
Adrià Rubirola et al.
Journal of chromatography. A, 1493, 64-75 (2017-03-21)
This paper reports the development of a fully multiresidue and automated on-line solid phase extraction (SPE) - liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the determination of 24 priority substances (PS) belonging to different classes (pesticides, hormones or pharmaceuticals)...
Kouji H Harada et al.
PloS one, 11(1), e0146335-e0146335 (2016-01-06)
Neonicotinoids, which are novel pesticides, have entered into usage around the world because they are selectively toxic to arthropods and relatively non-toxic to vertebrates. It has been suggested that several neonicotinoids cause neurodevelopmental toxicity in mammals. The aim was to...
Ellyn E Ritchie et al.
Environmental toxicology and chemistry, 38(10), 2111-2120 (2019-06-19)
The use of neonicotinoids in agriculture is a critical environmental protection issue. Although there has been considerable research on pollinator exposure and aquatic toxicological effects, few studies have investigated the chronic impacts on soil-dwelling species. Given the application of neonicotinoids...

Food additives & contaminants. Part B, Surveillance, 14(1), 30-39 (2020-12-05)
Risks posed by pesticide residues in infant food urge for protection of the most vulnerable part of our population. In the current study a total of 54 samples of infant food (juice and purée) were collected on the Serbian market....
