Ultra trace quantification of chromium(VI) in food and water samples by highly sensitive catalytic adsorptive stripping voltammetry with rubeanic acid Full text
2012
Abbasi, Shahryar | Bahiraei, Atousa
A simple and highly selective and sensitive catalytic adsorptive stripping voltammetric procedure for determination of ultra trace levels of chromium(VI) on hanging mercury drop electrode is reported. The method is based on the adsorptive preconcentration of the Cr(III)–dithiooxamide (rubeanic acid) complex and the utilization of the catalytic reaction in the presence of nitrate. At optimized conditions the calibration graph is linear from 0.01 to 6ng/ml and detection limit is 0.002ng/ml for accumulation time of 50s. The interference of some common ions was studied and this method has been applied to the determination of chromium in food and waste water samples with satisfactory results.

On new moon day when Moon passes between Earth and Sun solar eclipse can be seen from Earth. Although solar eclipse is a fascinating astronomical event, even in today’s fast, modern and civilized life, people have not been able to go away with superstitious beliefs related to outer space activity behind solar eclipse. These misbelieves eventually lead to great socio-economic losses due to discarding of cooked food and drinking water that was exposed to the eclipse directly or indirectly. So considering these misbelieves a study was conducted to see possible biological effects of solar radiations during solar eclipse on bacteria responsible for water borne and food borne diseases. E. coli, S. aureus, B. subtilis, S. typhi, which are known water and food borne pathogens, were exposed to solar radiations throughout the eclipse period. The effect of these radiations on the survival and growth rate of these organisms was assessed by suitable method and compared with that on control day. When such comparison was made, it indicated that there was no statistically significant effect of solar eclipse on the survival and the growth rate of these organisms. Hence, we insist dumping the cooked food or drinking water after solar eclipse should be avoided.

Food Business Operators (FBO) are responsible for the safety of the food they produce and in Ireland those under the regulatory control of the Department of Agriculture, Food and Marine are required to provide summary data on microbiological tests undertaken as part of their food safety controls. These data are provided to the National Reference Laboratory through the 25 private laboratories undertaking the testing. RESULTS: Over the five-year period Salmonella sp. was isolated from 0.7% of the 254,000 raw meat or raw meat products tested with the annual prevalence ranging from 0.5 to 1.1%. Poultry meats were consistently more contaminated than other meats with higher recovery rates in turkey (3.3%), duck (3.3%), and chicken (2.5%) compared with meats of porcine (1.6%), ovine (0.2%) and bovine origin (0.1%). Salmonella sp. was also isolated from 58 (0.06%) of the 96,115 cooked or partially cooked meat and meat products tested during the reporting period with the annual percentage positive samples ranging from 0.01 to 0.16%. A total of 50 different serotypes were recovered from raw meats over this period with the greatest diversity found in poultry samples (n = 36). Four serotypes, Kentucky, Typhimurium, Agona and Derby accounted for over 70% of all isolates detected on FBO testing over the period 2005 to 2009. CONCLUSIONS: Capturing microbiological data generated by Food Business Operators allows the regulatory sector access to a substantial amount of valuable data with the minimum financial outlay.

The table of contents for this item can be shared with the requester. The requester may then choose one chapter, up to 10% of the item, as per the Fair Dealing provision of the Canadian Copyright Act | The aim of the project is to develop a modelling framework that will increase resource use efficiency along with policy coherence, through interlinkages of water, energy and food security factors in remote and impoverished areas. The case study centres around the municipality of Elundini, located in the North of the Eastern Cape. The area is a catchment for the Umzimvubu River and is characterised by rugged, mountainous terrain and abundance of water. A nexus orientated modelling framework is applied that develops interventions to supply power and piped water where it is lacking, as well as improving agricultural practices.
