Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. Pb is harmful to human organs even at trace levels, and once it accumulates in the body, it causes inhibition of hemoglobin formation and neurological disorders. Cd is even classified as human carcinogen [Group 1 - according to International Agency for Research on Cancer]. It is reported that Cd leads to severe kidney problems which can be fatal and is also associated with brittle bones and liver problems. Rice, as the most widely consumed cereal grain in Asia/China, can quickly pick up Pb and Cd from toxins, pesticides and fertilizers in the soil, thereby endangering the health of millions of people through their diet. Therefore, it is extremely important to develop a simple, reliable method to monitor the levels of Pb and Cd in rice. According to Chinese national standard GB 2715-2016 Hygienic Standard for Grain, the maximum concentrations of Pb or Cd in grains must be below 0.2 mg/kg; the allowable level in the European Union is the same [EC 1881/2006]. The official technique for the determination of heavy metals in both cases is graphite furnace atomic absorption spectroscopy (GFAAS, GB/T 5009. 12-2017, GB/T 5009-2017. 15 and EN 14083:2003). Samples can be pretreated using various methods, including microwave digestion, hot block digestion, dry ashing, and hot plate digestion. It is found that these conventional digestion procedures are always complicated and time-consuming (two-four hours or even longer). Plus, conventional sample preparation techniques require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. Special PTFE vessels are needed for microwave digestion; however, reusable utensils might also cause cross contamination.
Mycotoxins are toxic secondary metabolites produced by fungi, and are capable of causing disease and death in both humans and animals. Sample preparation is a critical step in the successful analysis of mycotoxins in food matrices.

However, due to the complexity of food matrices, this approach will often result in irreproducible matrix effects. To overcome these problems and improve sensitivity, this application note details the use of online solid phase extraction (SPE), coupled to an LC/MS/MS system for sample enrichment.

Rice represents a dietary staple for over half of the world's population. However, in recent years, concerns have been raised over the presence of high levels of arsenic (As), where this carcinogenic metalloid can be accumulated at levels far exceeding ambient concentrations. Since China is the world's largest producer of rice, the Chinese government released a national standard method in 2014 for food safety – GB 5009.11– to aid the evaluation of As species in rice and rice products. In this document, HPLC-ICP-MS is identified as the preferred analytical technique. In this study, five arsenic species were characterized in a commercial rice sample and certified reference material using a gradient anion-exchange method in accordance with GB 5009.11. The analysis was performed using a PerkinElmer NexSAR™ HPLC-ICP-MS speciation solution, consisting of a NexSAR inert HPLC coupled to a NexION® ICP-MS.
Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. Pb is harmful to human organs even at trace levels, and once it accumulates in the body, it causes inhibition of hemoglobin formation and neurological disorders. Cd is even classified as human carcinogen [Group 1 - according to International Agency for Research on Cancer]. It is reported that Cd leads to severe kidney problems which can be fatal and is also associated with brittle bones and liver problems. Rice, as the most widely consumed cereal grain in Asia/China, can quickly pick up Pb and Cd from toxins, pesticides and fertilizers in the soil, thereby endangering the health of millions of people through their diet. Therefore, it is extremely important to develop a simple, reliable method to monitor the levels of Pb and Cd in rice. According to Chinese national standard GB 2715-2016 Hygienic Standard for Grain, the maximum concentrations of Pb or Cd in grains must be below 0.2 mg/kg; the allowable level in the European Union is the same [EC 1881/2006]. The official technique for the determination of heavy metals in both cases is graphite furnace atomic absorption spectroscopy (GFAAS, GB/T 5009. 12-2017, GB/T 5009-2017. 15 and EN 14083:2003). Samples can be pretreated using various methods, including microwave digestion, hot block digestion, dry ashing, and hot plate digestion. It is found that these conventional digestion procedures are always complicated and time-consuming (two-four hours or even longer). Plus, conventional sample preparation techniques require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. Special PTFE vessels are needed for microwave digestion; however, reusable utensils might also cause cross contamination.

The elemental content of food products is very important, both in relation to nutritional and toxic elements. Nutritional elements can either be native to the food substance or can be added to enhance the health benefits. Toxic elements can enter food either through the environment or processing during production. Hopefully, toxic elements will be present at extremely low levels, while nutritional elements will be present at optimal levels. The elemental capabilities and dynamic range of inductively coupled plasma mass spectrometry (ICP-MS) make it ideally suited for the analysis of food materials. This work has demonstrates the ability of PerkinElmer’s NexION 300/350X ICP-MS to effectively measure macro-level nutritional elements in the same analysis run as lower-level elements, without having to dilute the samples.

Veterinary drugs are used in animal production to treat diseases, prevent infection and protect growth of animals, which helps provide quality marketplace. However the uncontrolled use may cause heavy human disease so regulatory agencies around the world have established maximum residue levels (MRLs) or tolerances of veterinary drugs in foods. Drug analysis is generally challenging, due to the complexity of sample matrices and diversity of analytes from various classes of chemical properties. In this study, a fast, sensitive and selective method has been developed for analysis of 73 veterinary drugs (covering 13 different chemical classes) in chicken samples by coupling solvent extraction method with LC/MS/MS.
Polycyclic aromatic hydrocarbons (PAHs), a class of complex compounds containing two or more benzene rings, are widely found in the environment and food. PAHs are formed during the incomplete combustion of organic matter, such as wood utilized in cooking and food preparation. They have attracted wide attention due to studies which have shown the teratogenicity and carcinogenicity of PAH compounds. For humans, food intake is one of the main sources of PAH exposure, and can be the result of contamination from anthropogenic sources, food processing or cooking practices. In this paper, a validated method employing accelerated solvent extraction (ASE) and gel permeation chromatography (GPC), followed by solid phase extraction (SPE) on silica and analytical determination by GC/MS was applied for the detection of PAHs in smoked meat. The results demonstrate that the method is suitable for the simultaneous determination of 24 PAHs in smoked meat with good efficiency, accuracy and reproducibility.
Polycyclic aromatic hydrocarbons (PAHs) can contaminate foods during smoking, heating, and drying processes that allow combustion products to come into direct contact with food. They can also enter food supply chains through contaminated air and water, and accumulate in various food chains. Regulations are in place to monitor PAHs levels in foods; the EU set a stringent maximum residue limit (MRL) for BaP in muscle meat of smoked fish and smoked fishery products at 2 µg/kg.2 In this study, seafood samples were prepared using a QueChERS extraction method followed by a dispersive solid-phase extraction clean-up step. The samples were subsequently analyzed by coupling a UHPLC system with a triple quadrupole mass spectrometer.
Nitrofurans are a class of broad-spectrum antibiotics that are widely used to kill or slow down the growth of bacteria in the aquaculture industry. The use of nitrofurans and their metabolites has been restricted by a number of countries and organizations within the European Union, United States and China, due to their harmful side effects to human health, and a Minimum Required Performance Limit (MRPL) 0f 1.0 µg/kg has been set for food, animal and aquaculture products. LC/MS/MS methods have been used for the detection of nitrofuran metabolites in many studies owing to the high sensitivity, selectivity and specificity of the methods. However, nitrofuran metabolites demonstrate low ionization efficiency with the electrospray ion source used in LC/MS/MS systems. Therefore, the use of a derivatization step for nitrofuran metabolites before extraction and LC/MS/MS analysis is crucial to meet the low regulatory limits of 1.0 µg/kg in food samples. The main purpose of this work is to determine the detection limits for nitrofurans using QSight® 210 LC/MS/MS system.
Beta-adrenergic receptor agonists (ß- agonists) are synthetic drugs utilized in the treatment of conditions such as asthma in humans, and are also used as a growth-promoting agent in food-producing animals. The use of ß- agonists in food-producing livestock has been either banned or regulated across many countries owing to human health concerns. To aid in the monitoring and detection of ß- agonists in livestock, a highly sensitive and selective analytical method has been developed, and is presented in this study. This LC/MS/MS method details the analysis of 13 ß- agonists in pork samples, and utilizes isotopically-labeled internal standards to compensate for matrix effects present in complex food matrices.
