“…For example, under the neutral soil pH, Pb 2+ is bound to clays, organic matter and iron (Fe) hydroxides (Tandy et al, 2017). In addition, cadmium seems to be less stable in soils compared with lead (Ahmadipour et al, 2015). Our study showed that organic matter content was lower in the area where bullets dropped (backstop berm), which is in accordance with the results observed by Murray et al (1997).…”

The aim of the study was to investigate the changes in physical properties and contamination with heavy metals of military shooting range soil. Field soil was collected from outdoor shooting range soils in central Lithuania. The shooting range is located in Alytus city. Physico-chemical examination showed that the pH value of the shooting range soil was described as alkaline (7.91-8.30). A decrease in organic matter content was established in soil samples taken from the backstop berm of a shooting range; moreover, increased soil density was discovered in all soil samples. The soil was heavily contaminated with Pb, Ni, Cd and allowable quantities of Cu. The backstop berm soil was heavily contaminated with lead (max. 653.33 mg/kg); nonetheless, the limit concentration of lead was exceeded in the backstop berm soil. The concentration of cadmium found in the shooting range area (0-400 meters) varied from 17.42 mg/kg to 39.07 mg/kg and was higher than the concentration in the backstop berm (p < 0.05). The limit concentration of cadmium, which is 3 mg/kg, was exceeded in all soil samples. Large amounts of nickel were found closer to the beginning of the firing line and decreased with an increasing distance from the firing line (r = 0.90, p < 0.05). The limit concentration of nickel in the soil (75 mg/ kg) was exceeded at 100 m, 200 m and 300 m distances.

“…Intensification of heavy metal pollution, occurs when mining is carried out in a crude manner and associated wastes are untreated and improperly dumped or discharged (Nwaugo et al, 2007). Heavy metals have serious ecological effect as a result of their toxicity and their accumulation in both sediment and biota because they are not biodegradable and undergo a global ecological cycle (Ahmadipour et al, 2014). run-offs, as well as dumps that have been confirmed to accommodate harmful minerals and chemicals that contaminate the soil, plant, water and air quality (Osuocha et al, 2015).…”

Bottom sediment qualities in Ihetutu minefield were assessed to ascertain the impact of Pb-Zn mining activities on the sediments from streams, rivers and ponds in the area. Levels of Cu, Zn, Fe, Ni, Mn, Pb, Cd and Cr and some physico-chemical parameters were measured in bottom sediments taken from four sampling stations (streams/mine pits) within Ihetutu minefield of Ishiagu which receives discharges from mining and human activities, and a control sampling station in Uturu (about 12 km away from study area). The study was conducted in four seasons (Rainy, Late Rainy, Dry, and Late Dry Seasons). Sample digestion was done with a temperature adjustable block digester. Heavy metal analysis was carried out with Flame atomic absorption spectrophotometer (FAAS) while other physico-chemical parameters were determined with standard field and laboratory procedures. Ranges of mean values of results obtained were; pH = 5.81-6.44, EC = 269.00-1545.00 µS/cm, Cl − = 43.30-112.33 mg/kg, alkalinity = 0.70-1.25 mg/kg, NO − 3 = 5.90-7.90 mg/kg, TOC = 0.81-1.75 mg/kg, TOM = 1.40-3.02 mg/kg, Cu = 4.74-50.93 mg/kg, Zn = 26.78-57.07 mg/kg, Fe = 1066.19-1764.05 mg/kg, Mn = 36.66-42.96 mg/kg, Ni = 4.02-17.19 mg/kg, Pb = 38.01-162.23 mg/kg, Cd = 1.01-25.90 mg/kg, and Cr = 1.23-1.62 mg/kg. Assessment of heavy metals pollution, using pollution indices revealed that Contamination factor ranged from moderate to very high degree of contamination while Pollution load index also showed a deterioration of bottom sediment qualities. Geoaccummulation index indicated moderate to very high pollution, especially with Cu, Zn, Pb, and Cd in the mine pit, while Enrichment factor indicated high enrichments and inputs from anthropogenic sources especially, the Pb-Zn mining activities. Pollution of the area by heavy metals was in the order of Fe > Pb > Zn > Mn > Cu > Ni > Cd > Cr. Highest positive correlation (r = 0.992) was between Pb and Cu while the highest negative correlation (r = −0.789) was between Ni and Mn.

“…In recent years, heavy metals pollution of the aquatic environment has become a worldwide problem due to their persistence in nature and their capacity to accumulate in living organism [7]. Ahmadipour et al [8] reported that heavy metals have negative health implications due to their toxicity potential and tendency to accumulate in environmental media such as water, soil, sediment and other biological media. Several heavy metals persist in the sediment with varied concentrations most especially in fine grain [9].…”

The present study was carried out to assess the pollution status of heavy metals in the marine sediment in Ondo coastal area. A total of 36 sediment samples were collected from the three locations (Awoye, Abereke and Ayetoro) once in a month in 2015 covering both dry and wet season. The sediment samples were subjected to digestion and Atomic Absorption Spectrophotometer (AAS) was used to measure the concentrations of As, Cd, Cr, Cu, Fe, Mn, Ni, Pb, V and Zn. The measured concentrations data were used for evaluating the contamination level and accumulation status of heavy metals in sediment by employing several pollution indices: contamination factor (CF), degree of contamination (Cdeg), pollution load index (PLI), enrichment factor (EF) and index of geoaccumulation (Igeo). The results showed that Fe had the highest average concentration values of 248.00§ 20.00 and 324.33§ 5.80 mg/kg at Awoye sampling site for wet and dry season, respectively while the highest mean concentration of Mn were 271.77±9.50 and 295±10.06 mg/kg at Abereke and Ayetoro, respectively. The contamination factor (CF) values for As, Cd and Mn were 1 < CF < 3, indicating a moderate contamination. The results of Cdeg were ranged from 8.6 to 12.5 for both dry and wet season except in Ayetoro site that had 7.8 in the wet season. The PLI values were 0.47, 0.50 and 0.54 (<1) for Abereke, Awoye and Ayetoro sites, respectively, denoting unpolluted conditions. The EF values for Pb and Ni obtained from all the sites ranged from 20.8 to 38.9, showing their significantly enriched in sediment. The Igeo values of As, Cr, Fe, V, Zn and Cu were less than one (Igeo <1) for the three sampling locations in both seasons, implying that the sediments in the study area are practically uncontaminated by these metals. Pb had the Igeo values of 2.80 and 2.85 during dry and wet season at Awoye sampling site while Ni had 2.57 at Abereke only in the dry season. The heavy metals in sediment might be derived from the upstream rivers from the top soil, mechanically weathered rock materials and anthropogenic activities.
