The analysis indicated that about 5% of the initial deposit remained in the aerial vegetation after 6 years, more than two thirds of intercepted 137Cs being transferred to the soil due to throughfall. The simulations indicated that foliar uptake might have contributed between 40% and 100% to the activity transferred to stem wood. The activity concentration in canopy organs rapidly decreased in the first few months then more slowly, according to an effective half-life of about 1.6 years. The activity level in the organic layer peaked in summer 2011 then decreased according to an effective half-life of 2.2 years. After a rapid increase in 2011, the contamination of mineral horizons continued to increase more slowly, 85% of 137Cs incoming through the organic layer being retained in the 0-5 cm layer according to a mean residence time longer than in the upper layer (7 against 1.5 years).The presence of dissolved organic matter (DOM) can impact metal sulfide (MeS) precipitation and mobility. Thiol containing ligands such as cysteine have been shown to be effective capping agents in single metal MeS studies, allowing NPs to persist in oxic environments. In this study, both single (Cd or Zn) and multi-MeS (Cu, Pb, Cd, Zn, and As) nanoparticle (NP) formation was characterized to understand the impact of the thiol cysteine (CYS) on early stage (3 h) MeS NP behavior. Short duration single metal batch experiments, in the absence and presence of CYS, confirmed that MeS species readily formed solids with limited dissolved fraction; however, multi-metal systems exhibited divergent behavior reflecting a wider range of NP sizes and an increased dissolved concentration. Multi-metal batch experiments revealed that metals were generally sequestered into MeS solids in accordance with MeS solubility products (i.e., from least to most soluble Cu > Pb ~ Cd > Zn). CYS concentrations in excess of sulfide (101 CYSS ratio) stabilize
