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.

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 The study has been conducted with inductively coupled plasma optical emission spectrometry to determine the content of toxic heavy metals, macroelements, and essential elements in two species of bivalves of commercial interest in the Canary Islands: the Mediterranean mussel (Mytillus galloprovincialis, Lamarck 1819) and the razor clam (Ensis directus, Conrad 1883). The study included 40 samples corresponding to 20 specimens of each species acquired from fishmongers on the island of Tenerife. E. directus had higher levels of metals, except for B, Cd, Na, and Zn (0.98, 0.02, 2,006.93, and 15.07 mg/kg, respectively) compared with those in M. galloprovincialis, B, Cd, Na, and Zn (2.67, 0.12, 2,267.7, and 22.27 mg/kg, respectively). In both bivalve molluscs, the maximum limits established by European legislation on food for human consumption were not exceeded. Likewise, the estimated daily intakes for the toxic metals Pb and Cd were below the admissible daily intakes.

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.

Sanitation Systems

<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>
