Sampling and Isotope Analysis of Agricultural Pollutants in Water Excerpt :

Stable isotope techniques can help identify the sources of water pollution associated with agricultural activities. Knowing the origin of nutrients or contaminants is essential to improve agricultural practices. To ensure the quality of stable isotope analysis, appropriate sampling and sample preparation are crucial. This publication presents methods for surface water sampling and sample processing through micro-diffusion and bacterial denitrification combined with laser spectroscopy. Information on such methods is often described in a very summarized and non-comprehensive way without proper illustration of every step. This publication aims to bridge this gap for scientists, technicians and students. It presents a selection of standard operating procedures providing guidance in water sampling and sample preparation that are mandatory when conducting reliable isotope analysis on water.

Progress in Food Contaminant Analysis Excerpt :

'Analysis of Food Contaminants' was published in 1984 by Elsevier Applied Science Publishers and 10 years later I was asked to consider producing an updated second edition. Surprisingly little has really changed in a decade in terms of the public interest in food safety and the continued vigilance of Government in monitoring the food supply for contaminants. This means that food contamination in itself is still a very relevant topic. However, much has changed in terms of the techniques now employed in trace analysis. The 1984 book used a combination of an analytical technique and a specific food contaminant problem area per chapter (each written by a specialist) which resulted in a multi-authored text which was mostly application based but provided a good introduction to the 'how' in terms of applying techniques to real problems. Rather than producing a second edition of this text, it seemed on reflection more sensible to produce a new and complementary book, using the same formula as before of application plus technique, but to concentrate on contaminant areas of current interest and to highlight recent advances in techniques. Thus, the present book 'Progress in Food Contaminant Analysis' has originated as a follow-up to 'Analysis of Food Contaminants'.

Analysis of Chemical Contaminants in Food Excerpt :

How many times have we thought with concern about the possible contamination of food? Pollution, agricultural treatments, technological treatments, and packaging are the best-known human sources of toxic substances as food contaminants. The present book contains 11 original research papers representing various approaches of identifying and measuring toxic residues in food materials. The analytical determination of food contaminants is an indispensable tool in characterizing the adverse effects and unexpected toxicity related to food intake. No risk assessment would be possible without data from the analysis of food contaminants. This Special Issue is an interesting overview of recent methods and is highly representative of a broad worldwide outline, collecting authors from ten different countries and four continents. Very different toxics are described, from volatile organic compounds to heavy metals and from highly polar chemicals to classical organic contaminants. A wide range of analytical techniques are portrayed, including sample preparation and clean-up methodologies, classical chromatographic and hyphenated spectroscopies, and the latest high-resolution mass spectrometry applications. The presented works consider a varied selection of foods: the studied matrices are meat, fishery products, fruits, and miscellaneous beverages.

An Examination of Analytical Methods Towards the Complete Analysis of Contaminants of Emerging Concern in Wastewater and Wastewater Impacted Surface Water Soils and Crops Excerpt :

The presence of contaminants of emerging concern (CECs) in the environment is a growing field of research for analytical environmental scientists. CECs are a class of anthropogenic pollutants not regulated by governmental agencies, and their potential deleterious environmental and human impacts are largely unknown. One of the main sources of CEC entry into the aquatic environment is wastewater treatment plant (WWTP) effluent as the treated water is often released into bodies of water, such as river and streams. Because most WWTPs were not designed to remove organic micropollutants, many CECs are poorly removed in traditional WWTPs and persist in the treated effluent waters. As a model system for study, the University Park WWTP treats the wastewater from the Penn State main campus. Following primary and secondary treatment, effluent water is then disinfected using sodium hypochlorite ("chlorine contact") and pumped for spray irrigation of over 500 acres of agricultural and forested lands called the Living Filter. The full characterization of CECs in environmental matrices requires the use of both targeted and non-targeted analysis employing a variety of advanced analytical techniques and multi-residue extraction methods. Comprehensive two-dimensional gas chromatography (GCxGC) coupled to time of flight mass spectrometry (TOFMS) is utilized for the separation and analysis of complex samples, such as wastewater. In these studies, GCxGC-TOFMS has been utilized for the non-targeted analysis of wastewater influent, effluent, and Living Filter irrigation water. Over the course of three years, these samples were investigated for CECs, revealing a new class of benzotriazole corrosion inhibitors and their transformation products. The tentatively identified chloromethyl-benzotriazole isomers were detected at higher concentrations in the effluent and irrigation water than the influent. Upon further investigation with a lab-scale synthesis, it was determined that the methyl-benz

Identifying Future Drinking Water Contaminants Excerpt :

With an increasing population, use of new and diverse chemicals that can enter the water supply, and emergence of new microbial pathogens, the U.S. federal government is faced with a regulatory dilemma: Where should it focus its attention and limited resources to ensure safe drinking water supplies for the future? Identifying Future Drinking Water Contaminants is based on a 1998 workshop on emerging drinking water contaminants. It includes a dozen papers that were presented on new and emerging microbiological and chemical drinking water contaminants, associated analytical and water treatment methods for their detection and removal, and existing and proposed environmental databases to assist in their proactive identification and regulation. The papers are preceded by a conceptual approach and related recommendations to EPA for the periodic creation of future Drinking Water Contaminant Candidate Lists (CCLs--produced every five years--include currently unregulated chemical and microbiological substances that are known or anticipated to occur in public water systems and that may pose health risks).

Manual of Standard Operating Procedures for Selected Chemical Residue and Contaminant Analysis Excerpt :

Food safety is an important global public health and trade matter, with chemical hazards occupying centre stage due to associated acute and chronic health outcomes. There is also an increasing need to address antimicrobial resistance concerns. While food remains a major vehicle for exposure to these hazards, related matrices cannot be ignored. Animal feed for instance may contain drug or pesticide residues as well as mycotoxins that could carry-over to food either as parent compounds or their metabolites of toxicological relevance. Contaminated water is also another medium of potential exposure to food hazards. A concerted effort is required to address the need for a safe food supply and one critical stakeholder is the testing laboratory. While this requires trained and capable analysts as well as reliable instrumentation, analytical methods are a major need. Development and validation – to ensure fitness of purpose – and availability of these methods is a necessity. This manual, consisting of several Standard Operating Procedures (SOPs), presents another opportunity for laboratories to address gaps in analytical methods and/or expand their options. The manual contains techniques for analyzing certain mycotoxins such as aflatoxins, fumonisin and ochratoxin in matrices that include milk, edible vegetable oil and animal feed etc. A range of veterinary drug residues including permitted and prohibited substances in animal matrices including fish, are also addressed. Several pesticide residues in cereals, fruits and vegetables are also covered. A couple of methods for analysis of selected metals are also presented.
