Gas liquid chromatography-flame ionization detector (GLC-FID) residue analysis of carbamate pesticide in freshwater fish Labeo rohita

Polycyclic aromatic hydrocarbon (PAH) accumulation in different common sole (Solea solea) tissues from the North Adriatic Sea peculiar impacted area

“…In addition, the lack of significance of the correlation in muscle and liver could indicate that in these tissues PAHs have undergone a degree of enzymatic transformation due to depuration. In fact, the liver is the main detoxifying tissue and contains relatively high levels of detoxifying enzymes (Leόn et al, 2013;Nagaraju et al, 2014;Sun et al, 2016).…”

Testicular oocyte development and other toxic effects in the common hourglass tree frog exposed to three commercial insecticide formulations

“…The estimated median lethal concentration (LC 50 ) and median ChE inhibitory concentration (IC 50 ) in, D. melanostictus for 96 h were 24 and 2.1 mg/L carbosulfan respectively (Samarakoon and Pathiratne, 2017) 48 h, 72 h, and 96 has 28.5, 25.9, and 24.0 ppm respectively. The median lethal concentration of carbosulfan for freshwater fish Labeo rohita is 1.2 mg/L at 96 exposure period (Nagaraju and Rathnamma, 2014). Acute toxicity or the LC 50 of an organism varies depending on the chemical.…”

Determination of methiocarb pesticide using differential pulse voltammetry with a boron-doped diamond electrode

“…Similarly to the abovementioned carbamates, the main principle of action is an inhibition of acetylcholinesterase (ACHE) in the central nervous system. Herein, a collection of about twenty such approaches can be presented, comprising the employment of HPLC, 12-19 gas chromatography, [20][21][22][23][24][25] or the so-called QuEChERS, a special extraction methodology 26-28 that enables one to determine a wide variety of carbamates-oen, in simultaneous analyses-in different types of samples. In particular this is the reason why the latest applications of pesticides are turning in favour of carbamates, including methiocarb; a typical example being its use for reducing the overgrowth of zooplankton.…”

“…[9][10][11] In order to monitor and control the content of MTC, there is an increasing demand for reliable, sufficiently sensitive, and accessible analytical methods with the respective procedures. Herein, a collection of about twenty such approaches can be presented, comprising the employment of HPLC, [12][13][14][15][16][17][18][19] gas chromatography, [20][21][22][23][24][25] or the so-called QuEChERS, a special extraction methodology [26][27][28] that enables one to determine a wide variety of carbamates-oen, in simultaneous analyses-in different types of samples.…”
