Toxic Heavy Metals

Heavy metal contamination of poultry meat is a critical issue for human health due to associated risks of cytotoxicity and systemic pathologies after ingestion of such metals. A total of twenty chicken liver samples were collected from markets of Erbil city and analyzed for ten heavy metals contents by Inductively Coupled Plasma Optical Emission Spectrometry. The targeted metals were cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), mercury (Hg), zinc (Zn) and selenium (Se). The average concentrations (mg/kg) of targeted trace elements were 0.06±0.027, 0.06±0.05, 2.05±0.34, 1.85±0.47, 0.15±0.17, and 33.53±5.24 for Co, Cr, Cu, Mn, Ni, and Zn respectively. Copper (Cu) levels significantly exceeded the maximum permissible limit of WHO. Moreover, the average concentrations of toxic heavy metals and selenium were 0.07±0.037, 0.278±0.10, 0.11±0.083, and 2.01±0.454 mg/kg for Cd, Pb, Hg, and Se respectively. Hg and Pb levels exceeded the permissible limits of WHO. Higher levels of Cu and Hg in poultry may pose a serious threat to consumers which demand countermeasures and precautions to be taken. Iraqi Standards Authority and relevant official institutions are strongly recommended to regulate safe disposal of heavy metal waste in the environment to reduce animal exposure to such metals.

Abstract Medicinal plants possess several metals obtained naturally or through pollution. The study evaluates the genotoxic potentials and the presence of essential elements and toxic heavy metals in Sesbania sesban var. bicolor (leaves), Cyperus compressus (roots) and Asparagus racemosus (roots), which are used as anthelmintics in the traditional medicine of the Santhals in India. Genotoxicity study was performed as per Organization for Economic Co-operation and Development (OECD) guidelines in rats. Element contents were evaluated using inductively coupled plasma-optical emission spectrometry (ICP-OES). Administration of S. sesban var. bicolor (400 mg/kg), C. compressus (700 mg/kg) and A. racemosus (500 mg/kg) did not cause any abnormalities in the chromosomes. Elemental analysis revealed the presence of lead (5.00 ± 0.05, 4.98 ± 0.01, 4.99 ± 0.07 ppm), cadmium (4.99 ± 0.04, 4.90 ± 0.03, 5.00 ± 0.08 ppm) and arsenic (0.98 ± 0.03, 0.41 ± 0.05, 0.92 ± 0.03 ppm), respectively. Although genotoxic potentials were lacking, the presence of toxic heavy metals in them is a cause of concern.

<p>Pit latrine (PL) is one of the most common disposal systems for human excreta in low-income countries but because it is a hole in the ground, infiltration of liquid effluent into the soil can continuously occur. Poor sanitation systems permit the spread of heavy metals in urine to water bodies especially the groundwater. This study investigated the accumulation of heavy metals in shoots of corn plants irrigated with urine. A pot experiment with corn was conducted under greenhouse conditions. Urine was diluted to 3:1 ratio (water and urine respectively) and was compared to control (water only). Using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), heavy metals such as Boron, Barium, Cobalt, Copper, Iron, Manganese, Nickel, Silicon, Strontium and Zinc were detected in shoots of all plants with contents ranging from 0.22 to 2,487.44 milligram (mg) per kilogram (kg). The higher amounts detected in urine irrigated plants than the control proved the presence of the metals in the urine. Reuse of urine will definitely benefit farmers while at the same time reduce the risk of heavy metal contamination in groundwater.</p>

Sorption Behavior

Calcium alginate (CA) beads as a green sorbent were easily fabricated in this study using sodium alginate crosslinking with CaCl2, and the crosslinking pathway was the exchange between the sodium ion of α-L-guluronic acid and Ca(II). The experimental study was conducted on Cu(II), Cd(II), Ni(II) and Zn(II) as the model heavy metals and the concentration was determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The characterization and sorption behavior of the CA beads were analyzed in detail via using scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The adsorption experiments demonstrated that the CA beads exhibited a high removal efficiency for the selective adsorption of Cu(II) from the tetra metallic mixture solution and an excellent adsorption capacity of the heavy metals separately. According to the isotherm studies, the maximum uptake of Cu(II) could reach 107.53 mg/g, which was significantly higher than the other three heavy metal ions in the tetra metallic mixture solution. Additionally, after five cycles of adsorption and desorption, the uptake rate of Cu(II) on CA beads was maintained at 92%. According to the properties mentioned above, this material was assumed to be applied to reduce heavy metal pollution or recover valuable metals from waste water.

In order to evaluate the effects of different transportation hubs on cultivated soil and apricots, macro and micro elements and heavy metal contents of fruit, leaf, kernel and soil samples collected from apricot orchards located at the border of the railroad, the motorway, the airport, and an orchard far from transportation modes were detected by ICP/OES (inductively coupled plasma / optical emission spectrometry). The results indicated the highest Cd, Pb and Ni contents of soil, fruit, and kernel samples under impacts of railroad transportation modes, whereas the highest contents of leaf were found under motorway side. All fruit samples contained higher amounts of Cd and Pb compared to permissible limits of FAO/WHO, and contents differentiated between sampling locations. There were no correlative relations found between transportation modes and macro-micro element contents. As a conclusion, in terms of heavy metal contamination, the orchards located at railway sides have the highest risk and this was followed by motorway side.

Abstract Pet owners often don’t acknowledge the need for home-prepared diet formulation by a trained professional and may use recipes from sources such as the internet. Macronutrient and mineral composition of home-prepared diets were analyzed and compared to NRC and FEDIAF recommendations, and heavy metal concentrations were analyzed and compared to FDA maximum tolerable levels (MTL) for dogs and cats. Recipes of home-prepared diets for adult dogs (n = 75) and cats (n = 25) were evaluated. Analyses of protein, fat, and fiber were performed according to AOAC, and mineral and heavy metal analyses were performed using inductively coupled plasma optical emission spectrometry (ICP-OES). None of the diets supplied recommended levels of all nutrients evaluated, and more than 84.0% of diets presented three or more nutrients below recommendations. Nutrients with most levels below recommendations were calcium and potassium in recipes for dogs and iron and zinc in recipes for cats. As for heavy metals, levels of lead, cobalt, mercury, uranium, and vanadium were above MTLs. Results suggest that home-prepared diets may be a health risk to dogs and cats if not properly formulated. Furthermore, the chronic heavy metal intake must be better elucidated in order to understand the full impact of results.

The increase in the number of heavy metal emitting sources in industrial areas is a serious issue in pollution science. Sohar Industrial Port (SIP) area is located in the northern part of Oman where different industrial activities like petrochemical production, metal processing, and waste disposal are prevalent. This study comprehensively identified the presence and quantities of heavy metals in the soils of Sohar Industrial Port area and traced their origin to geogenic or anthropogenic sources. Bulk geochemical and mineralogical analyses were carried out on all samples. Environmentally available and bioavailable heavy metals were extracted by diethylenetriaminepentaacetic acid (DTPA) and were finally analyzed using Inductively Coupled Plasma-Optical Emission spectrometry (ICP-OES). The environmentally available metals that showed higher concentrations when compared to international standards were Ni and Cd. The geochemical evidence showed a strong geochemical signature of the ophiolite rocks in the soils as indicated by the significant correlation between Cr and Ni (P< 0.05). In addition, the Cd content showed significant correlations with Ni and Cr (P< 0.05). Other metals like Pb and Zn, possibly also were geogenic in origin, but with significantly elevated concentrations in samples close to a national highway (P< 0.05). The present study demonstrated the significance of understanding the geological framework of an industrial area, which is already imposing high background concentrations of Cr, Ni and Cd, and also the possible anthropogenic impacts in the cases of Pb and Cd that exceeded internationally permissible limits.

Cultivated Soybean

Soybeans are species of legume that has become one of the most widely consumed food in the world, because they are easy to cultivate and very beneficial for human health. The quality of the cultivated plants, including the content of toxic heavy metals depends to a large extent on the contaminants present in the soils in which they are grown and the method of fertilization. Through this research we aim to highlight the degree of accumulation of cadmium, chromium, cobalt, copper, nickel, lead and zinc in relation with the cultivated soybean genotype and fertilization. Three soy varieties (Cristina, Felix and Onix) were cultivated in an experimental field located at Cojocna Experimental Didactic Center of the University of Agricultural Sciences and Veterinary Medicine of Cluj-Napoca. The above-mentioned heavy metals were determined from the harvested mature soybean seeds using inductively coupled plasma-optical emission spectrometry, using an Avio 200 instrument. The obtained results demonstrated that the accumulation of heavy metals in soybean seeds is influenced by the cultivated genotype and fertilization; the Onix variety is more prone to the accumulation of heavy metals, while the highest values of the above listed metals were recorded in the case of fertilizing with „Fertitel”.

Wastewater Samples

Background. In recent years, mitigation of groundwater contamination resulting from the limited availability of freshwater for domestic use has become an important issue. The presence of heavy metals in water could have adverse effects on both plant and animal life. Objectives. The main objective of the present study was to determine possible heavy metal contamination in groundwater around Al-Buraihi sewage station in Taiz, Yemen and to understand possible sources of contamination and their relationships with groundwater. Methods. Wastewater samples were collected from a wastewater stabilization pond from Al-Buraihi sewage station and borewell water samples were collected from the vicinity. The presence of heavy metals was quantified using inductively coupled plasma-optical emission spectrometry (ICP-OES). Pearson correlation test was performed to understand the relationship between wastewater and groundwater samples. Results. Physical variables including pH, electrical conductivity (EC), dissolved oxygen (DO) and temperature and elements such as silver (Ag), arsenic (As), aluminum (Al), barium (Ba), boron (B), cadmium (Cd), chromium (Cr), iron (Fe), molybdenum, nickel (Ni), selenium (Se) and zinc (Zn) exceeded the permissible limits recommended by international standards in wastewater samples. Conclusions. Treated sewage wastewater in the study area is not suitable for irrigation as the elements/heavy metals are accumulated in soil and plants and may be accumulated in humans and animals through bio-accumulation. In addition, these heavy metals reach the water table and aquifers through percolation, thereby polluting groundwater. Competing Interests. The authors declare no competing financial interests.

Due to food safety issues and human health risk, heavy metal concentration through food chain is a concerned problem worldwide. There are several reports on transfer of non-biodegradable heavy metals from soil to animals by direct contamination or through feed. Hence, the present study was undertaken to estimate the presence of heavy metals chromium and copper in chicken liver samples (n=54) which were collected in and around Tirupati region of Andhra Pradesh, India. These samples were analyzed for the presence of chromium and copper by using Inductively Coupled Plasma–Optical Emission Spectrometer (ICP-OES). The excess levels of chromium considered to be carcinogenic and copper leads to tissue injury. The results of this study revealed that the range of chromium is between 0.009 to 0.091ppm and for Copper is 0.006 to 2.54 ppm in chicken liver samples which is not significant and within prescribed tolerance limit.

Abstract The study investigated the level of heavy metal contamination in plants {maize (Zea mays) and tomato (Solanum lycopersicum L.)} from thirty soil samples of three locations (Epe, Igun and Ijana) in the Ilesha gold mining area, Osun State, Nigeria. Total concentrations of As, Cd, Co, Cr, Cu, Ni, Pb and Zn were determined using atomic absorption spectrophotometry. Spatial variations were observed for all metals across the locations which was adduced to pH and the clay contents of the soils of each location. The results showed that heavy metals are more concentrated in the areas that are closer to the mining site and the concentrations in soil and plants (maize and tomato) decreased with increasing perpendicular distance from the mining site, indicating that the gold mine was the main sources of pollution. The mean concentrations of heavy metals in plants (tomato and maize) samples were considered to be contaminated as As, Cd and Pb respectively ranged from 0.6 - 2.04 mg kg-1, 0.8 - 5.2 mg kg-1, 0.8 - 3.04 mg kg-1 for tomato and respectively 0.60 - 2.00 mg kg-1, 1.50 - 4.60 mg kg-1 and 0.90 - 2.50 mg kg-1 for maize. These levels exceeded the maximum permissible limits set by FAO/WHO for vegetables. In conclusion, monitoring of crops for toxic heavy metals is essential for food safety in Nigeria.
