This study aimed to quantify the extent of heavy metal, non-metal and metalloid level of Campomanesia adamantium pulp obtained from area crossed by road of the high large vehicle traffic and intensive agriculture modern farm, and for monitoring the health risks associated with pulp human consumption. For this purpose, three spots located between this area, ripe fruits were collected in roadside, bush and margin-farm. Pulp samples were digested by microwave-assisted equipment, and mineral elements were quantified by ICP OES. The mineral elements average demonstrated no statistical difference observed between this pulp (p > 0.05). The heavy metals and metalloid concentrations that exceeded FAO/WHO standards are ordered Pb > As > Mo > Co > Ni > Mn > Cr. Therefore, among these metalloid and heavy metals, As, Pb and Cr were found higher in farm-margin > roadside > bush (1.5 × 10-3, 1.1 × 10-3 and 6.2 × 10-4) respectively. Therefore, As is the most important metalloid with higher levels in farm-margin, roadside and bush (1.5 × 10-3, 1.1 × 10-3 and 6.2 × 10-4 > 10-6–10-4 and 3.33, 2.30 and 1.34 > 1) respectively, to total cancer risk and hazard quotient, if 100 g daily of pulp are consumed.

This study aimed to quantify the extent of heavy metal, non-metal and metalloid levels in the Campomanesia adamantium pulp obtained from an area crossed by road experiencing high large vehicle traffic and intensive agriculture modern farming, to monitor the health risks associated with pulp consumption by humans. For this purpose, in three spots located within this area, ripe fruits were collected on the roadside, bush and farm-margin. Pulp samples were digested by microwave-assisted equipment, and chemical elements were quantified by ICP OES. The concentrations of K, Pb, Se, Fe, Mo, Zn, Co, Ni and Mn in the pulp collected in roadside/bush points showed statistical differences (p < 0.05). The heavy metals and metalloid concentrations that exceeded FAO/WHO standards were ordered Pb > As > Mo > Co > Ni > Mn > Cr. Therefore, among these metalloid and heavy metals, As, Pb and Cr were found to be higher in farm-margin > roadside > bush (1.5 × 10−3, 1.1 × 10−3 and 6.2 × 10−4), respectively. Therefore, As is the most important metalloid with higher levels in farm-margin, roadside and bush (1.5 × 10−3, 1.0 × 10−3 and 6.0 × 10−4 > 10−6–10−4 and 3.33, 2.30 and 1.34 > 1), respectively, to total cancer risk and hazard quotient, if 10 g daily of pulp are consumed.

This study aimed to assess the nutritional and trace elements composition of selected forest fruits sold for human consumption in Port Harcourt. Fruit contamination by heavy metals is an issue of global concern. Nondegradable elements bioaccumulations in tissues and organs have deleterious effects in man. Three (3) Agroforestry fruits species; (Spondias cytherea L. (Anacardiaceae), Syzygium malaccense (L.) Merr. & L. M. Perry Myrtaceae and Cola pachycarpa K. Schum. Malvaceae) were purposefully selected and sourced from three strategically located markets namely; Oil mill, Choba and D/line fruit markets. The fruit species were procured and washed with distilled water and the edible parts extracted, chopped and sun dried properly. The nutritional composition was analyzed using 18th edition of the Association of Official Analytical Chemist while trace metals were analysed using PIXE Accelerator. Spondias cytherea yielded high percentage of crude Protein (8.373±0.1) and Fibre content (11.73±0.03), while Syzygium malaccense was rich in Fat (7.17±0.02) and Ash (4.17±0.04). Moisture content was highest in Cola parchycarpa (12.63±0.05). PIXE Accelerator analysis revealed that the fruits contain high concentration of trace metals; S. malaccense contained Mg (1170±237.0ppm), Si (60.02±68.95ppm), Al (14.89±7.71ppm), Fe (10. 60±4.11ppm), Rb (3.20±0.00ppm) and Ti (1.82±0.00ppm). C. parchycarpa had Zn (6.22±11.80ppm), Cr (1.60±0.75 ppm), Mn (0. 71±0.87ppm) and Cu (0.38±0.33ppm). Ni (0.16 ppm) was found only in S. cytherea fruit. The forest fruits are rich in nutrients vital for healthy growth but the level of heavy metals (Mg, Al. Cr, Fe and Zn) in each of the fruits were above WHO/FAO permissible limit, therefore excessive consumption on a daily/weekly routine should be avoided.

This study was based on determining concentration of essential and toxic heavy metal in coconut water available at a local Hazaribagh area in Dhaka, Bangladesh. All essential minerals, if present in the drinking water at high concentration or very low concentration, it has negative actions. In this study, fifteen samples and eight heavy metals were analyzed by Atomic Absorption Spectroscopy (AAS) method which was followed by wet ashing digestion method. The concentration obtained in mg/l were in the range of 0.3 to 1.5, 7.77 to 21.2, 0 to 0.71, 0 to 0.9, 0 to 0.2, 0.9 to 17.3, 0.1 to 0.9, 0 to 0.9 and 0 to 0.7 for Fe, Ni, Cu, Cd, Cr, Zn, Pb and Se respectively. From this data it was concluded that any toxic heavy metals like Cd, Cr, Pb and Ni exceed their toxicity level and some essential nutrients were in low concentration in those samples.

In this study, the level of arsenic (As), lead (Pb) and cadmium (Cd) and also essential elements in beer samples consumed in Turkey were investigated using the inductively coupled plasma mass spectrometry (ICP-MS) method. The heavy metal-induced non-carcinogenic and carcinogenic risks were calculated. For essential elements, the calculated estimated daily intake of iron (Fe), copper (Cu), selenium (Se) and cobalt (Co) from beer consumption were compared with their toxicity reference values. Tukey post-hoc test showed that As was found at a significantly higher level when compared to Pb. Also, a significant correlation was found between As level and alcohol by volume percent. All samples had a hazard quotient and hazard index <1, indicating no non-carcinogenic risk from exposure to single or multiple heavy metals. Some samples exceeded the threshold limit of acceptable cancer risk for As in the high beer consumer group. This assessment showed that in addition to health implications based on the alcohol content of beer, there might be a carcinogenic risk associated with the heavy metals content of these beverages.

The aim and objective of the study was to isolate and characterize heavy metal tolerant microorganisms from tannery effluents. Six effluent samples were collected aseptically and their physical and chemical parameters were determined. A total of 40 bacterial colonies were isolated from these effluent samples. Among them, six bacterial isolates were characterized provisionally as Alcaligenes aquamarinus, Bacillus coagulans, Bacillus firmus, Enterobacter cloacae, Pseudomonas alcaligens and Pseudomonas mendocina based on morphological, cultural and biochemical characteristics. The survibality and tolerance to heavy metals (Cr and Cu) of these isolates were examined. All the isolates were found to grow at high concentration of CuSO4 (95ppm/ml) and varying degrees of chromium (K2Cr2O7). The highest tolerance was shown by Alcaligenes aquamarinus. These heavy metal tolerant organisms could be potential agents for bioremediation of heavy metals polluted environment.Bangladesh J Microbiol, Volume 29, Number 1, June 2012, pp 23-26

Determination of  heavy  metal  content  (Hg, Pb, Cd, Cu, Cr, Zn) in some seafoods collected from  Muara  Angke  Fish  Auction  Place  were carried out during February to July 1979. The results showed  that Zn  content  in seafoods a nalyzed  was always much higher than the other heavy metals. The concentration levels of  the  six  heavy  metals observed were low. It is almost of the same level as the metal concentration of  other  seafoods  observed  in various parts of the world oceans, but still lower  than the maximum standard set  for human  consumption  as  established  by   Tasmania, Australia and  World Health Organization. The  mean  per capita  consumption of  fish  in Jakarta is only  about 165 g  per week, while  the  Provisional Tolerated Weekly Intake for Hg, set by WHO/FAO at 300 ug level, would be attained by consuming 1500 g Rastrelliger sp., or 698 gPenaeus setiferus, or 545 g Sepia sp., and or 1250 g Pecten sp.  Therefore,  at   present the  level of metal content in fishes sold at TPI  Muara  Angke  can be  considered  as  not  dangerous  to human health as long as these quantities are not surpassed.

Keban Dam Lake is the second largest dam lake in Turkey. In addition, it has the feature of being one of the most important dam lakes in our country in terms of both aquaculture potential and electricity generation. In this study, fish samples belong to Capoeta trutta caught from Örencik region of Keban Dam Lake were used. The concentrations of some heavy metals (copper, iron, zinc, chromium, nickel, cadmium, arsenic and mercury) in muscle of Capoeta trutta and the potential health risk from consumption of this fish species were examined. In addidion, the relationship between the heavy metal levels and some biological aspects of fish (weight, length and sex) were determined. As a result of the study, it was determined that the most and the least accumulated heavy metals in the muscle tissue of Capoeta trutta were zinc and cadmium respectively. The concentration of heavy metals showed differences according to weight, length and sex of fish. The results were found indicated that heavy metal levels in the muscle tissue of Capoeta trutta are below the tolerable values recommended by EPA, WHO and FAO. Therefore, there is not any risk for human consumption of this fish species.

AbstractThe present study was conducted to determine the culturable bacterial profile from Kestopur canal (Kolkata, India) and analyze their heavy metal tolerance. In addition to daily sewage including solid and soluble wastes, a considerable load of toxic metals are released into this water body from industries, tanneries and agriculture, household as well as health sectors. Screening out microbes from such an environment was done keeping in mind their multifunctional application especially for bioremediation. Heavy metals are major environmental pollutants when present in high concentration in soil and show potential toxic effects on growth and development in plants and animals. Some edible herbs growing in the canal vicinity, and consumed by people, were found to harbour these heavy metals at sub-toxic levels. The bioconcentration factor of these plants being <1 indicates that they probably only absorb but not accumulate heavy metals. All the thirteen Grampositive bacteria isolated from these plants rhizosphere were found to tolerate high concentration of heavy metals like Co, Ni, Pb, Cr, Fe. Phylogenetic analysis of their 16S rDNA genes revealed that they belonged to one main taxonomic group — the Firmicutes. Seven of them were found to be novel with 92–95% sequence homology with known bacterial strains. Further microbiological analyses show that the alkaliphilic Bacillus weihenstephanensis strain IA1 and Exiguobacterium aestuarii strain CE1, with selective antibiotic sensitivity along with high Ni2+ and Cr6+ removal capabilities, respectively, can be prospective candidates for bioremediation.

Background: Environmental pollution with toxic heavy metals can be lead to the possible contamination of rice. Rice is a staple food widely consumed in the urban and rural parts of Liberia daily. Rice is cultivated in approximately 113 countries and a fundamental source for energy and protein. Objective: The study assesses selected heavy metals (As, Pb, Cd, Se, and Cr) concentration in selected imported rice and traditionally grown rice and bulgur wheat in Liberia. Methods: Six grade of imported rice, Bulgar wheat, and traditionally grown rice were purchased from the Duport Road and Red-Light markets in Greater Monrovia and analyze using X-ray Fluorescence Spectrometer. All data were analyzed using XLSTAT, and data was used to calculate the risk factor of each rice sample. Results: The mean concentration of heavy metal found in the rice as follow: As, 1.31ppm; Cd, 9.42ppm; Cr. 12.3ppm; Se, 5.73ppm; and Pb, 1.75ppm. The estimated daily intakes (EDIs) were calculated in combination with the rice consumption data. The mean intakes of As, Cd, Cr, Se, and Pb through rice were estimated to be 1.32, 9.42. 12.4. 5.74, and 1.75 mg/kg BW/day. Chromium has the average estimated daily intake. The combined hazard index for the heavy metals in each sample and the total cancer risk for each sample contributed most significantly to a cancer risk of rice consumption during adult life expectancy.Conclusion: The selected heavy metal concentration from the rice sample was above the FAO/WHO reference Standard but was within the range of the contaminant level except for chromium, which is above the accepted range. However, the hazard index and the total cancer risk indicate a potential non-carcinogenic and carcinogenic risk.

 Objective: Ulva reticulata is a marine edible green seaweed widely distributed along the coastal lines of India. The present study was designed to screen the phytochemicals and evaluate heavy metals content of U. reticulata collected from Rameshwaram, Tamil Nadu, India, in the perspective of assessing their therapeutic value and/or safety in relation to its uses.Method: The seaweed sample was subjected to extraction with solvents of different polarities (methanol, ethanol, acetone, chloroform, and petroleum ether) and screened for phytochemicals according to standard methods. Heavy metal analysis was also performed with the dried sample powder using inductively coupled plasma optical emission spectrophotometer (ICP-OES).Result: Preliminary phytochemical analysis revealed the presence of reducing sugar, proteins, flavonoids, glycosides, alkaloids, and anthraquinones. ICP-OES indicated the seaweed to contain relative amount of heavy metals in the order of iron (Fe) > chromium (Cr) > Zinc (Zn) > nickel (Ni) > copper (Cu) > lead (Pb) - cadmium (Cd) and is within the permissible limits set by the WHO/FAO, except Fe and Cr.Conclusion: The different solvent extracts of U. reticulata showed the presence of the number of phytochemicals. Furthermore, the present study has revealed the presence of heavy metals in U. reticulata which can be a representative picture of the dissolved metals in the aquatic phase.
