We successfully used a lanthanide labelling technique to quantify the uptake of submicrometre PS particles in lettuce and wheat. The europium chelate Eu–β-diketonate dopping PS (PS-Eu) particles were easily synthesized and accurately quantified and visualized within the crop plants.
Rice systems face the dual challenge of producing more and being more efficient in the use of water, labor, nutrients, and pesticides. An article published in Nature Communications on Dec 9 assessed performance of 32 rice cropping systems, altogether accounting for 50% of global rice cropland.
