Determination of inorganic arsenic species (As3+ and As5+) in muscle tissues of fish species by electrothermal atomic absorption spectrometry (ETAAS)

Levels, trends and risk assessment of arsenic pollution in Yangzonghai Lake, Yunnan Province, China

“…It was reported that the arsenic levels in fish were 0.05-1.4 g/g (wet weight) [24] in Lake Michigan, 6.1-11.8 g/g (dry weight) [25] and 2.12-15.2 g/g (dry weight) [26] in Lake Manchar, Pakistan, 0.038-0.309 g/g (dry weight) [27] in River Neretva, Croatia, 0.396-12.58 g/g [28] in southeastern Spain and 0.57-1.15 g/g [29] in five different fish species in Back Bay, Great Slave Lake, near the city of Yellowknife, NT, Canada. It was also reported that the arsenic contents in freshwater fish were respectively 1.6-3.8 and 7.9-22.2 g/g in non-contaminated and contaminated areas of Thailand [30], 0.097-1.32 g/g in Bangladesh [31], and 0.27-10.3 g/g [32] in Brazil.…”

Nafion stabilized ibuprofen–gold nanostructures modified screen printed electrode as arsenic(III) sensor

“…The results of As(III) quantification by the two methods are quite closer and hence validate the performance of our developed sensor. Looking at the results in Table 2, we say that river water and ground water have sufficient amount of As(III) that exceeds the WHO recommended value of 10 ppb [16,18]. This may be due to the contamination of river water via different types of discharges from industries related to As(III) applications while that in ground water is owing to the underground rocks and ores of As(III) containing salts.…”

“…Hence it is extremely desirable to select a highly sensitive, selective and simple analytical technique for monitoring As(III) in the environmental samples. Different techniques employed for As(III) determination in the environment include, Electro-Thermal Atomic Absorption Spectrometry (ETAAS) [16,18], Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) [19] and Electro-analysis [20]. The later technique is superior to others in terms of facile methodology for sample preparation, low cost of instruments, simplicity in operation and excellent sensitivity.…”

Inorganic Arsenic Determination in Food: A Review of Analytical Proposals and Quality Assessment Over the Last Six Years

“…109 Dos Santos Costa et al 110 determine arsenic species in rice by cloud point extraction (CPE) and ETAAS, using graphite tubes with different modifiers. Shah et al 111 determine total As and iAs in samples of edible fish from the arsenic-contaminated Manchar Lake, Pakistan, and evaluated the estimated daily intake (EDI) of iAs. The method adopted allows the measurement of total As, after prior acidic digestion; whereas As(III) and As(V) are separated by two sequential steps with chloroform as the extracting agent and reducing As(V) to As(III).The corresponding extracts, as well as total As, are measured by ETAAS, using Mg (NO 3 ) 2 þ Pd as a modifier.…”
