Mycotoxins are a diverse group comprised of hundreds of secondary metabolic products of various fungal species. Several show marked toxicity in humans. Contamination of the food supply with mycotoxins is increasingly prevalent, and can occur during growth, harvest, transportation, processing or storage. Techniques to reduce mycotoxin concentration after contamination are expensive, unreliable and sometimes reversible. Therefore, the removal of contaminated products from the food chain is a primary means of...
Control Composting Odors, Naturally: Municipal sludge is often composted in indoor facilities or composting sheds. These areas create significant odor control challenges. Ecosorb products, either evaporated or atomized in concentrate form with nozzles or humidifying fans, control industrial odors even in very large composting facilities.
Highly pigmented foods, such as spinach, require cleanup prior to analysis for pesticide residues. A dual-layer SPE tube containing graphitized carbon and aminopropyl on silica (NH2) is often used because; Carbon removes pigments and sterols and NH2 removes fatty acids, polar pigments, organic acids, and sugars. Removing these matrix materials reduces interferences that can lead to ion suppression in LC-MS, inlet contamination in GC-MS, and column contamination for both techniques.

A group of 30 compounds was selected, representing pesticides, acaricides, insecticides, and fungicides. These samples were analyzed using Supel™ QuE QuEChERS and an Ascentis® Express RP-Amide HPLC Column.
Fungicide carbendazim can some times be used to combat mold on citrus fruits including oranges. Recently, low residue levels of the fungicide were reported to be present in the bulk orange juice import shipments to the USA. Because this compound can persist through processing steps and may be found in the final consumer product, many government agencies have established maximum residue limits (MRLs) to ensure the safety of their population.
Presented here is a single method, involving fast and effective QuEChERS...
Herbicides are used throughout the world to combat the growth of unwanted plant life. These polar compounds are hydrophilic, so they may find their way into drinking water sources.
While gas chromatography has historically been the preferred technique for analysis of herbicides in water samples, the use of LC-MS/MS for this application is gaining acceptance. This is due to the power of MS/MS to provide detailed identification of multiple
analytes, but also in part due to the variety of HPLC stationary phases...
Delta-T Devices supplies high quality, research grade equipment to help growers monitor and control irrigation using proven technology:
improve water use efficiency
reduce fertiliser application rates
enhance crop development
Accuracy and ease of use make SM300 Soil Moisture Sensors well suited to irrigation applications. Readings can be used to optimise irrigation scheduling, or the SM300 can be installed as part of an automatic irrigation system. The sensor`s compact size allows it to be installed in plant pots or grow bags.
Cambridge based Delta-T Devices specialises in instruments for environmental science, in particular: agronomy, plant physiology, eco-physiology, data logging, meteorology, soil moisture, solar energy studies and environmental monitoring.
Abattoir & Slaughterhouse waste is a potential incubator of bacterial, viral, prion and parasitic pathogens, capable of infecting both animals and humans. A quick, cost effective and safe disposal method is essential in order to reduce the risk of disease following animal slaughter.
The Aquaculture industry is one of the fastest growing segments in the agricultural industry accounting for over 1.13 billion dollars in the USA alone. However, this industry is suffering with several water quality challenges requiring sustainable aquaculture water treatment solutions to enhance fish health, and population yield while meeting environmental discharge regulations. The challenges facing aquaculture companies include emerging growth rates of specific bacteria and viruses, water usage, and environmental...
Agro-meteorological application (AgMet) are becoming more and more important. With a rising world population, agricultural production has to become more efficient. Water is precious and scarce, pesticides are expensive and harmful to the environment if they get into the soil.
The agriculture industry is a water intensive industry that needs a constant contaminant free water supply to ensure high harvest yields and healthy farm livestock. Agriculture in the U.S. is dominated by large, specialized crop and animal farms. These industrial farms focus on short-term productivity, often at the cost of creating environmental and public health problems. This focus on short term productivity, requires agriculture water treatment solutions and specific soil additives that are sustainable and...
