“…The copper content was three times higher in honeydew than in the other three honey types, as it was observed by Chua et al [2012] and Chudzinska & Baralkiewicz [2011], ranging between 0.644 and 5.491 mg/kg. Still trace amount of copper is essential for the formation of haemoglobin, namely oxygen carrying blood component.…”

“…Precision is described as the degree of variability given by the expression of results, not taking into account the infl uence of the sample (sample variability). The precision was evaluated as the relative standard deviation of 10 repeated determinations for one sample [Chudzinska & Baralkiewicz, 2011]. Table 1 shows the coeffi cient of variation for each element.…”

“…There are many studies that use the multi-elements to classify honeys. Chudzinska & Baralkiewicz [2011] have used Al, B, Ba, Ca, Cd, Cu, K, Mg, Mn, Na, Ni, Pb and Zn to classify honeydew, buckwheat and rape honeys from Poland. They observed that K, Al, Ni and Cd were the parameters that best predicted the authenticity of honey.…”

“…Digestion with an acid in combination with microwave irradiation has been a widely used method because it improves the efficiency of analysis and reduces or eliminates the risk of sample contamination or analyte loss (Chudzinska and Baralkiewicz 2011;De Blas Bravo et al, 2007;Llorent-Martínez et al, 2011).…”

“…This technique has been employed for the determination of trace metals in olive oil (Llorent-Martínez et al, 2011), honey (Chudzinska and Baralkiewicz 2011), tomato (Bressy et al, 2013, and particularly in tea. The number of studies on the application of this technique to tea has increased in recent years (Chudzinska and Baralkiewicz 2011;Llorent-Martínez et al, 2012;Pilgrim et al, 2010), but these Q. Han et al 1110 studies only dealt with identifying the geographical origin of tea samples, and not with associating location with the types of tea.Sample digestion is a critical step in most analytical methods for the routine determination of trace elements in food samples.Many procedures have been developed to shorten analysis time and minimize problems associated with solid sample pretreatment, such as sample contamination and analyte loss (Korn et al, 2008).Digestion with an acid in combination with microwave irradiation has been a widely used method because it improves the efficiency of analysis and reduces or eliminates the risk of sample contamination or analyte loss (Chudzinska and Baralkiewicz 2011;De Blas Bravo et al, 2007;Llorent-Martínez et al, 2011).However, special instruments are required, such as a microwave digestion oven, which is not found in every laboratory. Therefore, the development of a simple digestion method such as using a heating plate is necessary.…”

In this study, 35 black, oolong, and green tea samples from China were analyzed by inductively coupled plasma mass spectrometry after a digestion method was developed on the basis of a response surface methodology. Linear discriminant analysis of whole data sets was performed in order to discriminate and classify Chinese tea samples according to their origin and type. The analysis revealed an excellent separation between tea samples according to their type and origin with a discrimination efficiency of 100%. The varieties of selected elements in Chinese tea were analyzed based on their origins and types. Keywords: tea, ICP-MS, minerals and trace elements, authenticity IntroductionTea (Camellia sinensis L) is a highly popular nonalcoholic beverage consumed by over two-thirds of the world's population owing to its medicinal and refreshing effects (Karak and Bhagat 2010). Since tea contains several essential nutrients and trace elements, drinking tea is considered beneficial for human health.The presence of heavy metals at trace levels in tea has received much attention because they are directly related to health.The efficacy of discriminating the geographical origin of teas is complicated by disparities in growing conditions such as soil and climate . The attributes of tea according to its geographical origin are also often recognized and appreciated by the consumers. Therefore, the discrimination of tea according to its geographical origin is presently the focus of attention (MoredaPiñeiro et al., 2003). However, it is not easy to determine its geographical origin by sensory evaluation. On the other hand, since elemental composition can provide accurate information about the provenance (Cubadda et al., 2006) of a tea sample, it is possible to identify the origin of tea on the basis of its elemental composition.In general, based on the different processing methods, teas are classified as: unfermented green tea (GT), fully fermented black tea (BT), and partially fermented oolong tea (OT), which are the most popular and frequently consumed teas in the world (Han et al., 2014). The processing method used affects the concentrations of elements in the processed tea. Therefore, the discrimination of tea types based on elemental fingerprinting is very urgent and important.Because of its low limit of detection (LOD) and multi-element measurement capability (Salomon et al., 2002), inductively coupled plasma mass spectrometry (ICP-MS) is used in a number of food analysis laboratories for determining elements at trace and ultratrace levels (Walczyk 2001). Therefore, ICP-MS is considered to be one of the most effective tools for determining the provenance of tea (Chudzinska et al., 2012;Herwig et al., 2011). This technique has been employed for the determination of trace metals in olive oil (Llorent-Martínez et al., 2011), honey (Chudzinska and Baralkiewicz 2011), tomato (Bressy et al., 2013, and particularly in tea. The number of studies on the application of this technique to tea has increased in recent years (Chudzinska ...
