CAPILLARY ELECTROPHORESIS | Crop-Protecting Agents
Capillary eletrophoresis (CE) is becoming an advantageous technique for determining crop protecting agents as a result of its simplicity and high separation efficiency. Controversely, inappropriate limits of detection (LODs) and a lack of selective detectors restrict its applications. The present article provides a general idea of recent advances in off-column and on-column approaches to trace enrichment in analyzing real samples, and recapitulates the determination of crop-protecting agents by conventional CE as well as by emerging techniques, such as CE-laser induced fluorescence (LIF) or CE-mass spectrometry (MS). The usefulness of these approaches in food and environmental applications …

Incidence of heavy metals in the application of inorganic fertilizers to rice farming soils (Valencia, Spain)
The presence of Cd, Co, Cu, Ni, Pb, Zn, Fe and Mn in different inorganic fertilizers (urea, calcium superphosphate, iron sulphate and copper sulphate) are evaluated and the contribution of these metals to the soils in this way is estimated. The studied zone corresponds to rice farming and is at the north of Albufera Natural Park (Valencia, Spain). The results obtained show that Superphosphate is the fertilizer that contains the highest levels of Cd, Co, Cu and Zn as impurities. Copper sulphate and iron sulphate have the most significant contents of Pb, and are the only fertilizers in which Ni is detected. The most significant additions of impurities that the soil received by agricultural pr…
