Biuret in Urea
Biuret Formation
Commercial urea production is achieved from ammonia and carbon dioxide through an exothermic reaction that forms ammonium carbamate, which then dehydrates to form urea. During the production process, in addition to the reaction forming ammonium carbamate and urea, a side reaction occurs that results in the formation of biuret. Since the majority of urea produced is used for agricultural purposes, the biuret content in urea is of significant importance due to its harmful effects on plants.
Impact of Biuret on Plants
At higher concentrations, biuret can be toxic to plants whether applied through the leaves or the soil. Biuret disrupts the metabolism and nitrogen absorption in plants. High concentrations of biuret can lead to stunted growth or complete growth inhibition in plants.
Biuret Analysis
Sample Control, a leading laboratory for analytical testing is analyzing biuret using a selective HPLC-UV method.
Microplastics in Antartctic snow
Microplastic particles, defined as particles ranging from 5 mm to 1 µm, have recently raised concerns among the scientific community and the public. Various scientific studies have shown that microplastics, due to their specific physicochemical properties, can directly or indirectly impact the health of humans and other organisms in different ecosystems.
Analysis of 3-MCPD, 2-MCPD, and GE in Free and Esterified Forms
3-Monochloropropane-1,2-diol (3-MCPD), 2-Monochloropropane-1,3-diol (2-MCPD), and glycidyl esters (GE) are contaminants that can form during food production processes and end up in food products, posing a potential health risk to consumers.
