“…In soil fertilized with nitrogen/phosphorous/potassium (NPK) and manure, the soluble forms of heavy metals such as Cu, Ni, Pb, and Zn, are usually increased [ 16 ]. Soil fertilized with regular manure tends to have higher soluble Cu, Zn, and Mn concentrations than soil fertilized with mineral fertilizers due to higher contents of Cd, Cu, and Zn in manure [ 17 , 18 ]. Excessive fertilizer has usually been applied in greenhouse soil, and the availability and accumulation of heavy metals related to soil pH, SOM, and soil nutrients in greenhouse soil need to be further investigated.…”

In China, greenhouse agriculture, which provides abundant vegetable products for human consumption, has been rapidly developed in recent decades. Heavy metal accumulation in greenhouse soil and products obtained have received increasing attention. Therefore, the availability and accumulation of cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn) and their association with soil pH, soil organic matter (SOM), inorganic nitrogen (IN), total nitrogen (TN), available phosphorus (AP), and planting year (PY) in greenhouse soils were analyzed. The results showed that the mean concentrations of available Cd, Cu, Ni, Pb, and Zn were 17.25 μg/kg, 2.89, 0.18, 0.36, and 5.33 mg/kg, respectively, while their suggested levels in China are 0.6, 100, 100, 120, and 250 mg/kg. Cd, Cu, and Zn might be mainly originated from fertilizer application. A lower soil pH significantly increased the available Cu, Ni, and Zn concentrations and reduced Cd, Cu, Ni, and Zn accumulation. A higher AP significantly increased the proportions of available Cu, Ni, and Zn and elevated Cd, Cu, and Zn accumulation. There was a strong positive correlation between Cd, Pb, and Zn availability and TN, while IN was negatively related to the availability and accumulation of Cu and Zn. It was concluded that chemical fertilizer application increased the availability of Cu, Ni, Pb, and Zn and the accumulation of Cd, Cu, and Zn. Manure application clearly elevated the accumulation and availability of Cd and Zn in greenhouse soil.

“…Although this is not fully repetition in the strict sense, it avoids the interaction effects of chemical substances (such as pesticides) diseases, insects and other factors. Indeed, many other comparable reported studies on long‐term experimental studies of greenhouse vegetable and fruit production systems also did not use fully replicated experimental designs ( Engindeniz , ; Ge et al., ; Liu et al., ; Tian et al., ; Yao et al., ). In this study, as mentioned in the Material and methods section, before the establishment of the three greenhouses, this area was a multi‐year vegetable field.…”

Intensive vegetable production in greenhouses has rapidly expanded in China since the 1990s and increased to 1.3 million ha of farmland by 2016, which is the highest in the world. We conducted an 11‐year greenhouse vegetable production experiment from 2002 to 2013 to observe soil organic carbon (SOC) dynamics under three management systems, i.e., conventional (CON), integrated (ING), and intensive organic (ORG) farming. Soil samples (0–20 and 20–40 cm depth) were collected in 2002 and 2013 and separated into four particle‐size fractions, i.e., coarse sand (> 250 µm), fine sand (250–53 µm), silt (53–2 µm), and clay (< 2 µm). The SOC contents and δ13C values of the whole soil and the four particle‐size fractions were analyzed. After 11 years of vegetable farming, ORG and ING significantly increased SOC stocks (0–20 cm) by 4008 ± 36.6 and 2880 ± 365 kg C ha−1 y−1, respectively, 8.1‐ and 5.8‐times that of CON (494 ± 42.6 kg C ha−1 y−1). The SOC stock increase in ORG at 20–40 cm depth was 245 ± 66.4 kg C ha−1 y−1, significantly higher than in ING (66 ± 13.4 kg C ha−1 y−1) and CON (109 ± 44.8 kg C ha−1 y−1). Analyses of 13C revealed a significant increase in newly produced SOC in both soil layers in ORG. However, the carbon conversion efficiency (CE: increased organic carbon in soil divided by organic carbon input) was lower in ORG (14.4%–21.7%) than in ING (18.2%–27.4%). Among the four particle‐sizes in the 0–20 cm layer, the silt fraction exhibited the largest proportion of increase in SOC content (57.8% and 55.4% of the SOC increase in ORG and ING, respectively). A similar trend was detected in the 20–40 cm soil layer. Over all, intensive organic (ORG) vegetable production increases soil organic carbon but with a lower carbon conversion efficiency than integrated (ING) management.

“…49 PCA and CA are mostly used to identify pollution sources in street dust and soil. 50,51 For the identification of sources of metal pollution in bioindicators these methods are rarely used. 52 The source appointment of the metal pollution in honeybees using PCA and CA was done only once.…”

Honeybees have been proposed and used as bioindicators for the last few decades, because of their nature. Until now they have mostly been used to determine the present pollution and to distinguish the differences between the sampling locations and the sampling periods. With the use of multivariate statistical methods honeybees can also be used to distinguish the origin of this pollution. In this study the concentrations of Al,
