“…At the same time, significant positive correlations were found between the Ni contents of the soils and Pb (r: 0.31***) and Fe (r: 0.40***) contents. In the study that Liu et al (2016) investigated the variability of heavy metal contents in the soil of typical Tibetan pastures, Ni and Pb were fount to be positively correlated. A significant positive correlation was also found between Pb content and Cu (r: 0.61***) and Fe (r: 0.44***) contents.…”

This study was aimed to determine the molybdenum content of meadow - pasture soil between Kırıkhan and Reyhanlı in Hatay province and to determine the relations of the molybdenum content with some heavy metals in the soil. For this purpose, two different depths (0-20 and 20-40 cm) representing grassland pasture lands and 80 soil samples from 40 different points were taken. Cadmium (Cd), Cobalt (Co), Nickel (Ni), Lead (Pb), Copper (Cu), Iron (Fe), and Molybdenum (Mo) contents were determined in the soil samples. The contents of the available Cd, Co, Pb, Cu, Fe, Ni and Mo of the soil were determined by reading the 0.005 M DTPA + 0.01 M CaCl2 + 0.1 M TEA extracts in the ICP instrument. The results of the research shows that the Cd contents of the soils are between 0.01-0.32 ppm; Co contents are from 0.01 to 4.97 ppm; Ni contents 0.00 to 20.00 ppm; Pb contents 3.00-67.00 ppm; Cu contents 0.26-7.48 ppm; The Fe contents are between 4.00 and 61.00 and the Mo contents are between 0.001 and 0.064 ppm. It was determined that there are significant positive relationships between Co, Ni, Pb, Cu and Fe contents of Mo in the soil. It was also determined that there are significant positive significant relationships between Cd and Co; Co with Ni, Pb, Fe and Pb and Cu, Fe and Cu and Fe. No heavy metal pollution was found when the heavy metal contents of the regional soils were compared with the limit values.

“…Correlation coefficients of Pearson for the heavy metals in the wild storage dumpsite of Kastamonu city are shown in Table 4. Liu et al (2016) noted a positive correlation between the Ni-Pb. Liu et al (2013) noted that all heavy metals (except for Pb) relatively low concentrations from 0.1 to 1 km from the dumpsite.…”

The aim of this study was to reveal the effects of domestic dumpsite on the some soil chemical properties in the surface soils in Kastamonu city. The soil samples were collected from the 5 different distances namely; Very adjacent (VA), Adjacent (A), Middle (M), Far (F) and Very far (VF). The results showed that the accumulation of heavy metal in the soil varied significantly with the distances. Among the heavy metals, the concentrations of Co, Cr, Cu (only A and VA), Zn (only A and VA), Ni (except for M) exceeded the Maximum Allowable Limit (MAL) for Turkey values. However, the concentrations of Mo, Pb and Cd were below the MAL limit values. When all results are considered, it can be stated that the waste dumpsites can negatively affect the environment. Therefore, we make sure that the dumped materials should be concentrated and recycled in order to decrease the amount of heavy metals in the dumpsites and in the soils around the dumpsites. In addition, phytoremediation, which is all the remediation technique available for metal contaminated soils, is the most costly, environmentally friendly and easy to apply. Phytoremediation can be used to remove, displace or reduce contaminants from soil by using plants that hyperaccumulate these contaminants.

“…The soil total organic carbon and nitrogen were detected using a TOC/TON analyzer (Shimadzu). An inductively coupled plasma-mass spectrometer (Thermo Fisher Scientific) was used to determine the heavy metal concentration in the soil samples, following the methods of previous studies. , To extract antibiotics from soil, 5% acetic-ACN and 0.1 M EDTA-McIlvaine buffer (1:1, v/v, pH = 4) was used. We used liquid chromatography coupled with tandem mass spectrometry (LC–MS/MS) to determine the concentration of antibiotics according to a published study .…”

In recent years, it has been increasingly recognized that soil animals are hidden reservoirs of antibiotic resistance genes (ARGs) and play a vital role in spreading ARGs in soil ecosystems. However, little is known about the variation of ARGs among different animals in the soil food web and effects of trophic levels and land uses on them. We characterized the antibiotic resistomes of 495 soil animal samples collected from six regions across China, including two different land uses. A total of 265 ARGs were detected in all animal samples, and relative abundances of ARGs in animals were significantly higher than in soils. In addition, significant differences in ARGs were observed among different animal groups. Twelve common ARGs were identified among all animal groups, accounting for 17.4% of total ARGs abundance. A positive and significant correlation was found between δ15N values (trophic level) and total ARGs abundance in animals. The relative abundance of ARGs in the soil food web from arable land was higher than forest land. Changes in soil antibiotics may indirectly affect animal resistome by altering soil ARGs. This study suggests that the risk of ARGs spreading through the food web is greater in arable than in forest ecosystems.
