Abstract

Bioavailability is a key parameter in assessing contaminant transfer to biota. However, the input patterns and soil use types may impact the metal bioavailability. Several soil parameters were measured including chemical properties, such as pH, organic C, and Cu solution/solid speciation, and biological properties, such as soil microbial biomass C (SMBC), seed germination, and root elongation, to evaluate the bioavailability of Cu contaminated soils from three different sources, i.e., non-ferrous metal mining, Cu-based fungicides, and Cu-smelting. The results revealed that free Cu2+ ion in soil solution and the ratios of Cu fractions to total Cu content in the solid phase could not be used to predict total Cu content in soils. The indexes of seed germination and root elongation appeared not to be good biomonitors of Cu contamination in soils, which were more sensitive to soil pH and soil organic carbon (SOC). Relationships between SMBC and soil Cu forms or the ratio of SMBC/SOC and soil Cu forms showed that free Cu2+ ion and humic acid-complexed Cu could significantly inhibit soil microbial activities. Our findings suggested that both metal chemical forms and biological bioassays should be considered as a complementary technique rather than an alternative to evaluate the metal bioavailability from different pollution sources.

      Copper contamination is particularly high in old vineyards (Komarek et al., 2010; Mackie et al., 2012) and in old orchards (Zhou et al., 2011; Wang et al., 2015) where the concentration of Cu in the topsoil (0–20 cm) can reach several hundred mg kg−1 soil. Soil Cu contamination in vineyard and orchard soils, although moderate compared to that of Cu-polluted soils located near Cu mines (Zotti et al., 2014), Cu smelting factories (Wang et al., 2014) or at wood preservation sites (Kolbas et al., 2020), has consequences for the functioning and the sustainability of these ecosystems since it has chronic effects on the dynamics of soil populations. Karimi et al. (2021) performed a meta-analysis of Cu ecotoxicity and reported that Cu harms soil microorganisms at concentrations above 200 kg Cu ha−1 (Cu of 67 mg kg−1 soil), which is currently the level found in many vineyard and orchard topsoils.

      Moreover, we must take into account the plant uptake regulation of an essential nutrient such as copper (Chaignon et al., 2003) and the release of the removed elements from the soil solid constituents to the soil solution (Maderova et al., 2011; Wang et al., 2014). The integration of chemical methods with biological assays in the evaluation of bioavailability can be useful to assess consequences for the environment of metal-contaminated soils (Wang et al., 2014). In a survey conducted in the plain area of the Campania region (southern Italy), surrounding the site where the experiments presented in this paper were performed, no significant correlations were found between the Cu content in the edible parts of crops (maximum value: 11.4 mg kg−1 f.w.) and total (maximum value: 570 mg kg−1 d.w.) or bioavailable (maximum value: 13.8 mg kg−1 d.w.) Cu soil content (Agrelli et al., 2017).

      JH-Soil, GX-Soil, and RZ-Soil represented the three main anthropogenic scorces for soil Cu pollution, namely mining tails, mineral smelting, and agricultural practices of Cu-containing pesticides, respectively. The pollution history of these soils was detailed in Wang et al. (2014), and the sampling positions for JH-Soil and GX-Soil were 32°04ʹ N, 119°05ʹ E and 28°20ʹ N, 117°14ʹ E, respectively. According to China Soil Classification System, JH-Soil, GX-Soil, and RZ-Soil were yellow-brown soil, red soil, and brown soil, respectively, and were further categorized as Stagnic Anthrosols, Udic Ferrosols, and Udic Luvisols based on the Universal Soil Classification System, respectively.
