Alternative method’s results for the non targeted determination of xenobiotics in food by means of high resolution and accuracy mass spectrometry
Springer Science and Business Media LLC - Tập 8 - Trang 1-8 - 2021
Rossana Scarpone, Rachele Rocchi, Federico Bacà, Roberta Rosato, Francesco Chiumiento, Giacomo Migliorati
The application of a high resolution and accurate mass spectrometry (HRAMS) approach to detect xenobiotics in different food matrices by means of non targeted determination by UHPLC-Orbitrap followed by data processing analysis was described. Three case studies were reported to demonstrate the possibility to identify unexpected substances in different food commodities overcomes targeted method. Th... hiện toàn bộ
Effects of per-household processes on the levels of chlorpyrifos residues in lettuce (Lactuca sativa)
Springer Science and Business Media LLC - Tập 3 - Trang 1-6 - 2016
Osei Akoto, Fredrick Addai-Mensah, Eric K. K. Abavare
The study was organized to evaluate residue levels of chlorpyrifos on Lactuca sativa that are likely to have accumulated on crop during cultivation and also examine the effect some pre-household treatment procedure on residue levels on the crop grown in a tropical and humid environment. Chlorpyrifos residue was extracted using acetonitrile. Subsequent detection and a quantification were done using... hiện toàn bộ
Variations in trace metal and aflatoxin content during processing of High Quality Cassava Flour (HQCF)
Springer Science and Business Media LLC - Tập 3 - Trang 1-5 - 2016
Hayford Ofori, Paa Toah Akonor, Nanam Tay Dziedzoave
High Quality Cassava Flour (HQCF) has gained popularity in most parts of West Africa because of its versatility in many industries. However, due to the processing techniques used HQCF may contain trace metals and aflatoxins. Imperatively, the safety of HQCF was assessed when the levels of trace metal and aflatoxin contaminants was determined at the various unit operation during HQCF production. Co... hiện toàn bộ

Cặn Ciprofloxacin và tác động của nó lên các biomolecule trong trứng của gà đẻ sau khi uống Dịch bởi AI
Springer Science and Business Media LLC - Tập 2 - Trang 1-7 - 2015
Md. Mustahsan Billah, S. M. Masud Rana, Mohammad Salim Hossain, Sayed Koushik Ahamed, Sujan Banik, Moynul Hasan
Nghiên cứu hiện tại được thiết kế để đánh giá cặn Ciprofloxacin và tác động của nó lên một số biomolecule (albumin, tổng protein và cholesterol) trong trứng của gà đẻ sau khi uống thuốc. Để đạt được mục tiêu đó, một nhóm (A) gà đẻ (n=20) đã được uống 10 mg/kg ciprofloxacin trong năm ngày liên tiếp. Nhóm thứ hai (n=10) là nhóm chứng không điều trị. Trứng được thu thập từ ngày đầu tiên của việc điều... hiện toàn bộ

Md. Shahadat Hossain, Md. Samiul Islam, Subrata Bhadra, Abu Shara Shamsur Rouf
The aim of this current study was to investigate the presence and to determine the contents of caffeine, preservatives and antioxidants in dairy products available in Bangladesh, one of the alarming countries in terms of food security. As high as 41 marketed dairy products, of both locally and internationally manufactured, were collected from local markets of Dhaka, Bangladesh in mid–2013 and then... hiện toàn bộ
Prevalence and molecular characteristics of Staphylococcus aureus in raw milk and milk products in Ethiopia: a systematic review and meta-analysis
Springer Science and Business Media LLC - Tập 9 - Trang 1-21 - 2022
Abiot Deddefo, Gezahegne Mamo, Samson Leta, Kebede Amenu
Staphylococcus aureus is an important opportunistic pathogen of raw milk and milk products, and the enterotoxins cause food poisoning. Milk and milk products are important reservoirs of enterotoxin-producing S. aureus. The aims of this systematic review were to estimate the pooled prevalence of S. aureus, including methicillin-resistant Staphylococcus aureus (MRSA), and to summarize their molecula... hiện toàn bộ
Determination of pesticide residues in honey: a preliminary study from two of Africa’s largest honey producers
Springer Science and Business Media LLC - Tập 3 - Trang 1-14 - 2016
Janet Irungu, Suresh Raina, Baldwyn Torto
The presence of pollutants in honey can influence honey bee colony performance and devalue its use for human consumption. Using liquid chromatography tandem mass spectrometry (LC-MS/MS), various clean-up methods were evaluated for efficient determination of multiclass pesticide contaminants in honey. The selected clean-up method was optimized and validated and then applied to perform a preliminary... hiện toàn bộ
Penicillin-G and oxytetracycline residues in beef sold for human consumption in Maroua, Cameroon
Springer Science and Business Media LLC - Tập 4 - Trang 1-11 - 2017

The contamination of food by chemical hazards is a worldwide public health concern and is a leading cause of trade problems internationally. Based on former work describing the prevalent use and misuse of antibiotics in cattle in the Far North Region of Cameroon, we designed a study to detect antibiotic (penicillin G and oxytetracycline) in beef sold for human consumption in Maroua (Cameroon).

Presence of microplastics in drinking water from different freshwater sources in Flanders (Belgium), an urbanized region in Europe
Springer Science and Business Media LLC - Tập 9 - Trang 1-11 - 2022
Ilias Semmouri, Maaike Vercauteren, Emmanuel Van Acker, Emmy Pequeur, Jana Asselman, Colin Janssen
Microplastics (MPs) are emerging contaminants of concern in aquatic ecosystems. Up to now, only a few studies about MP contamination in drinking water have been published. In this study, we analysed drinking water originating from ground water, surface water and treated sewage water for the presence of MPs, collected in different drinking water treatment plants (DWTP, n = 9) and water taps (TW, n ... hiện toàn bộ
