Pesticides are chemical substances used to control pests in an effort to increase crop production and quality, and food storage. The levels of pesticides in different environmental compartments, such as water, soil, agricultural foods, and products of animal origin, have become a relevant issue. In this study, the levels of pesticide residues in Sabarmati River of Gujarat, India, have been inve...

Background: Fish is a source of nutrition; however, toxic substances and heavy metals may enter human body due to consuming contaminated fish. The aim of this study was to investigate the levels of heavy metals and DDTs in Liza parsia, a fish species, and assess the health risk of the contaminants in the fish samples.  Methods: The extracted fish lipid was added with n-hexane and H2SO4 and was...

We present SIMION 8.1 Monte Carlo type simulations of the response function and detection solid angle for long lived Auger states (lifetime τ ∼ 10(-9) - 10(-5) s) recorded by a hemispherical spectrograph with injection lens and position sensitive detector used for high resolution Auger spectroscopy of ion beams. Also included in these simulations for the first time are kinematic effects particu...

In the last decades, the photon emission from highly charged ions has been found a versatile tool for exploring light-matter interactions in strong (Coulomb) fields [1]. Apart from a series of energy and angle resolved experiments, especially for the x-ray emission following the radiative electron capture (REC) into high-Z projectile ions [2], recent emphasis was placed on measuring the linear ...

We tested for residual pesticide levels in dried vegetables in Seoul, Korea. A total of 100 samples of 13 different types of agricultural products were analyzed by a gas chromatography-nitrogen phosphate detector (GC-NPD), an electron capture detector (GC-μECD), a mass spectrometry detector (GC-MSD), and a high performance liquid chromatography-ultraviolet detector (HPLC-UV). We used multi-anal...
