“…Some heavy metals such as iron, zinc, selenium is not dangerous and essential for living thing in small amount, however it may be hazardous if it is present in high concentration and some heavy metal was highly toxic in low concentration, such as cadmium, lead, arsenic, mercury and chromium (Bagal-Kestwal et al 2008). In this study, we measured heavy metals content in the muscle of N. peronii from two different areas (Pulau Kambing and Besut as illustrates in Figure 1) in order to determine the level of heavy metal contamination.…”

“…This suggested that the operation of the sensor should not be interfered with other chemicals that might be presented in the test medium. Fe III, Cu II, Ni II and MG II and were considered to be carcinogens and may also interfere with lead bismuth reaction [31][32][33][34]. Iron sulfate pentahydrate, cooper sulfate pentahydrate, nickel sulfate hexahydrate and magnesium sulfate heptahydrate were used.…”

Abstract:The accumulation of high levels of lead or lead ions in a human body is harmful, particularly to children. Its neurotoxic effect is profound, damaging the central and peripheral nervous systems, resulting in stunted growth, behavioral problems and learning disabilities. The major source of lead or lead ions comes from the drinking water and tap water. The assessment of the water quality, including lead or lead ion content, is usually completed by a regional water department professional. This assessment is time-consuming and requires expensive instruments and skilled operators.Therefore, there is a need to produce a simple-use and relatively inexpensive method to detect lead or lead ions in water samples. This research has developed a simple-use, cost effective sensor system for the detection of lead ions in tap water. An underpotential deposited bismuth sub-layer on a thin gold film based electrochemical sensor was designed, manufactured and evaluated.Differential pulse voltammetry (DPV) measurement technique was employed in this detection. Tap water from the Cleveland, Ohio, USA regional water district was the test medium. Concentrations of lead ion in the range of 8 X 10 -8 M to 8 x 10 -4 M were evaluated.This DPV detection system required 3 -6 minutes to complete the detection measurement. A longer measurement time of 6 minutes was used for the lower lead ion concentration. The selectivity of this lead ion sensor was very good, and Fe III, Cu II, Ni II and Mg II at a concentration level of 5×10 -4 M did not interfere with the lead ion measurement.

“…To protect human health and the environment, urgent steps are needed for the remediation of these heavy metals from food products. However, large-scale methodologies for heavy metals detection based on spectrometry and chromatography are costly, time-consuming, and require expertise (Bagal-Kestwal et al, 2008). A portable, rapid, and inexpensive detection method for heavy metals that can be used for on-site screening is necessary, and biosensors may be appropriate for this purpose.…”

Background: Foodborne pathogens are a growing concern with respect to human illnesses and death. There is an increasing demand for improvements in global food safety. However, it is a challenge to detect and identify these harmful organisms in a rapid, responsive, suitable, and effective way. Results: Rapid developments in biosensor designs have contributed to the detection of foodborne pathogens and other microorganisms. Biosensors can automate this process and have the potential to enable fast analyses that are cost and time-effective. Various biosensor techniques are available that can identify foodborne pathogens and other health hazards. Conclusions: In this review, biosensor technology is briefly discussed, followed by a summary of foodborne pathogen detection using various transduction systems that exhibit specificity for particular foodborne pathogens. In addition, the recent application of biosensor technology to detect pesticides and heavy metals is briefly addressed.
