“…The effectiveness of foliar applications of Cu as bactericides or fungicides is due to the fact that inorganic forms of this element are relatively insoluble in water and are not easily washed out from the foliage, thus providing much longer protection than other compounds (Fishel 2017). Nevertheless, there is scientific evidence in vineyards that Cu washing out from leaves cannot be negligible depending on the occurrence of rainfall (Pérez-Rodríguez et al 2016) and its energy (Pérez-Rodríguez et al 2015). It is important to note that the real effect of Cu is not as fungicide or bactericide (death of microorganisms) but, rather, as fungistatic or bacteriostatic (Richardson 1997).…”

High soil copper may result in adverse effects on natural and agricultural systems. Copper-based pesticides have long been used for control of microbial diseases on fruit tree productive systems. Although copper is relatively safe from a human health management point of view, it can be accumulated in agricultural soils, affecting soil microbiota and litter degradation. The purpose of this review was to collect the available information to critically discuss the role that litter may play in fruit tree productive systems, in terms of copper incorporation into the soil, where this element is used as a pesticide. To achieve this objective, we focused our review on (1) soil contamination by copper-based pesticides in fruit production systems, (2) soil copper behavior, (3) effects of copper contamination on soil organisms, and (4) copper-litter relation in soil. From this review, we can suggest that (1) litter is the main sink of metals coming from atmospheric fallout because it is a good complexing agent of cations, (2) litter decomposition depends on its quality and in soil microbial activity, and (3) soil and litter microbial activity is negatively affected by soil copper enrichment. Thus, under uncontrolled applications of copper-based pesticides in fruit tree productive systems, copper soil enrichment will generate a decrease in microbial activity, diminishing litter breakdown and decreasing dissolved organic carbon formation. This process will also decrease the soluble copper incorporation into the soil; however, this assumption remains unevaluated.

“…Our samples, which were placed in a debris dump for 16 months, contained about 0.001 % Na, which indicated that it contained 0.003 % salt (calculated from NaCl/Na proportion). This would be partly because of the wash-off effect of rain (Pérez-Rodríguez et al 2015;Konoplev et al 1996;Nasrabadi et al 2011). The wash-off function of fresh water was successfully confirmed with seawater-treated wood blocks (Supplementary material 4), and we think that the same washing-off procedure occurred on the debris due to rain.…”

There are only a few scientific data about the function of ecosystems after tsunami disasters. The ecosystems help the environment to recover after a disaster, and therefore, the research on its function is important. We estimated the seawater influences on wood degradation after a tsunami disaster by the growth of Trametes versicolor. The debris from the Great East Japan Earthquake on the pacific coast in March 2011 was used for the simulations. Its growth on debris was compared with those on seawater-treated woods, and the amount of sodium chloride was examined to know the approximate amount of salts in the samples. Sodium chloride contents were employed as an indicative parameter of sea salts, which contained many elements. As a result, this common white-rot fungus degraded wood debris in the same way as sound sapwood. Although the study was conducted at the laboratory level, this is the first report from the real debris, which assessed the fungal decomposition ability of the ecosystem after a tsunami disaster.

“…Simulation of elution by rain drops showed that adherents decreased Cu-losses from leaves within the first 30 mm of rain got decreased from 75-90% down to 10-25%, and increased the covered surface area per particle. Washout to the soil left the particles rather unchanged [2,3]. Within the soil, the Cu-containing particles get irreversibly adsorbed at humics and pedogenic oxides within a few hours, leaving exchangeable fractions within a few percent of total [4].…”
