“…The overall Cd, Pb and Hg levels in the muscle tissues of all the specimens analyzed were well under the proposed limit values. Results of cadmium contents for Sardine are comparable with those reported by Diop et al (2016) from Senegalese Coast and higher with those reported by Chahid et al (2013) and Vieira et al(2011). However, these authors reported higher levels of lead and mercury in the same species.…”

In the current study, ten elements contents (Fe, Zn, Mn, Cu, Cr, Co, Ni, Cd, Pb and Hg) have been measured in muscle and liver of four pelagic fish species (Engraulis encrasicolus, Sardina pilchardus, Scomber japonicus and Trachurus trachurus) from the north-west African coast (South Atlantic Moroccan coast), collected during summer and autumn seasons (July and December 2013, respectively). Significant differences in metal contents were found between the different species (p \ 0.05). Metals levels were also much higher in liver than those recorded in muscle tissues. The concentrations of Fe, Zn, Cd, Co, Cu and Pb were significantly higher in mackerel liver (p \ 0.05).While, in muscle, anchovy presents a higher content of Mn, Cu, Cr, Ni and Pb. A high level of cadmium was recorded in liver of the different species which can be attributed to an anthropogenic source (phosphate industry) and to natural sources (upwelling activities). The main concentration of toxic elements (Cd, Pb and Hg) recorded in the four edible muscles of pelagic fish species, under study, were below the established values by the European Commission Regulations and show that their effect on the consumers health can be considered as negligible.

“…Aquatic pollution studies attract the attention of many investigators (Balkıs et al 2013;Chahid et al 2014;Makedonski et al 2015;Araujo and Cedeno-Macias 2016). Determination of trace metal accumulation in various fish species from seas, lakes, rivers, and reservoirs have largely been conducted in food safety studies.…”

“…We found the levels of cadmium and lead in fish species were generally higher than Turkish legal standards (Anonymous, 2008). Chahid et al (2014) determined the mean levels of Cd and Pb found in fish from Atlantic Sea (Morocco) as 0.009-0.036 µg g -1 for Cd and 0.013-0.014 µg g -1 for lead. Authors suggest that these values were below acceptable levels for human consumption and thus cause no health problems for consumers.…”

“…Among the heavy metals, cadmium ions have attracted much attention because of their high toxicity and hazardous nature. 24) Cadmium is typically analyzed using prominent methods such as atomic absorption, 5,6) ion chromatography 7,8) and inductively coupled plasma-mass spectrometry (ICP-MS). 9,10) These spectrometric methods offer good precision and resolution, but they are expensive and time-consuming, involve complex operation steps and are not suitable for onsite detection.…”

High Sensitive Surface Plasmon Resonance (SPR) Sensor Based on Modified Calix(4)arene Self Assembled Monolayer for Cadmium Ions Detection

et al. 2015

In this work, a new chromogenic calix(4)arene was functionalized onto self assembled monolayer (SAM) of cysteamine for cadmium ions detection and tested by using SPR measurement. The functionalization of modified SPR sensor is based on the oxidation of calixarene-SAM alcohol group to quinone. Four interfering ions were used Cu 2+ , Co 2+ , Mg 2+ and Ca 2+ . pH of sensor in which the sensitivity of sensor is higher was optimized for cadmium ions and detection of ions was made in basic solution. Detection limit reached for Cd 2+ is lower than 10 ¹11 M with a dynamic response time of about 16 s when changing from 10 ¹6 M cadmium to 10
