In recent years there has been an increase in the contaminations of heavy metals on the environment. Government and private organization have shown their interest in the effect of dietary exposure to several heavy metals. These heavy metals have been implicated in the etiology of many diseases with high risk to humans. Canned tomatoes paste is one of the important health deterioting factors to human health in Ubani-Umuahia, Nigeria. In this study atomic absorption spectrophotometer was used to screen for nine heavy metals concentration in ten different brands of canned tomatoes paste sold at Ubani-Umuahia market in Nigeria. Human risk assessment was calculated using the collated data to evaluate the predictive risk of human health after the consumption of canned tomatoes paste. Results shows that lead and nickel were not detected in all the canned tomatoes. In comparison low concentrations of copper, iron, and manganese were notated but high concentrations of chromium and cadmium were detected in all the tested tomatoes pastes. Cobalt and zinc concentration was notated lower than permissible limit. The daily intake of copper, cobalt, manganese, chromium, cadmium, nickel, iron, zinc and lead were below their tolerable values in canned tomatoes. The predicted lifetime for carcinogens to occur was less than one (<1). Copper, cobalt, iron, and zinc were below the acceptable value for non-cancer risk with HQ <1.The risk of incurring cancer by ingesting canned tomatoes was within the lifetime predicted a range of (1.0E-6 to 1.0E-4). Finds suggest that prolong and persistent consumption of these heavy metals may cause toxicity and consequential heath challenges. J. bio-sci. 28: 1-11, 2020

In order to investigate the effect of treated wastewater on forage yield, nutrient elements and heavy metals in corn plants (Zea maize, 704 single cross), a field experiment was conducted in RCBD with three treatments in four replications in 2017. Irrigation with well water as first treatment, irrigation with wastewater as second treatment and irrigation with well water and wastewater was alternately applied as a third treatment. The results showed that the highest amount of forage corn yield, stalk and ear dry weight, plant height and leaf number and spade index were obtained in irrigation with wastewater. The highest nitrogen content of leaf and stalk and corn grain was obtained in irrigation with wastewater treatment and the least amount in irrigation with well water treatment was obtained. The amount of phosphorus and potassium measured in leaf and stalk of corn in all three treatments were not significantly different. Also, the highest amount of iron and zinc in leaf and stalk of corn was obtained in irrigation with wastewater treatment. The results showed that the amount of heavy metals including lead, cadmium and nickel in soils were not significantly different in all three treatments. According to the results, the use of urban wastewater not only does not cause soil and plant pollution to heavy elements, but also increases plant yield and nutrition.

Plants that are able to accumulate and tolerate extraordinarily high concentrations of heavy metals (hyperaccumulators) can be used for phytoremediation (removal of contaminants from soils) or phytomining (growing a crop of plants to harvest the metals). Two moss species, Bryum capillare Hedw. and Ceratodon purpureus Hedw., were tested as potential phytoremedies under in vivo conditions on a coal ash disposal site in the surroundings of Obrenovac (NW Serbia). The content of various heavy metals (iron, manganese zinc, lead, nickel, cadmium, and copper) in the mosses and substrata were investigated over a period of three years. Iron and zinc were found to have the highest concentration in the mosses.

Heavy Metals In Soils

The paper studies heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways. An adverse effect of railway transport on adjacent territories is shown. Railway transport and subjects of its support are permanent sources of pollution. Long-term emissions to the air are reflected by essential accumulation of tocsins in the top horizons of the soil. The authors reveal the amount of heavy metals in soils of the train removal station Ussuriysk JSC Russian Railways. To identify the coefficient of heavy metals concentration in soil samples of 8 trial areas of technogenic and anthropogenic zones of the city were analyzed. To identify local technogenic anomalies concentration coefficients were calculated. The authors concluded that the territory of the train removal station Ussuriysk JSC Russian Railways was very polluted. The south of the railway station is characterized by an average pollution level. The authors revealed high concentrations of Zn, Mn, Fe, Cu and Pb in soils of the trial sites with a high transport loading.

The vanadium contents of eight species of solitary ascidians for which quantitative data are lacking are reported. It is observed that the occurrence of the metal within the class does not conform to taxonomic groups, but instead occurs sporadically throughout. For example, the phlebobranch Chelyosoma productum was observed to contain 800 ppm vanadium, whereas in a second member of the same family. Corella willmeriana, the metal could not be detected. Corella willmeriana contained a substantial iron concentration. The stolidobranch Boltenia villosa was found to contain vanadium at a level previously observed only among the phlebobranchs.The vanadium content of Ciona intestinalis shows a linear dependence upon the dry weight of the animal, and can be estimated from a concentration value of ~ 90 μg vanadium per gram dry weight, independent of the size class of the animal. No significant seasonal variation in the vanadium concentration of C. intestinalis was observed.

ABSTRACT An iron-poor stream of nearly neutral pH polluted by mine tailings has been investigated for a natural phenomenon responsible for the polishing of heavy metals in mine wastewaters. A white mineralized mat, which was determined to be hydrozincite [Zn5(CO3)2(OH)6] by X-ray diffraction analysis, was observed in the stream sediments mainly in spring. The precipitate shows a total organic matter residue of 10% dry weight and contains high concentrations of Pb, Cd, Ni, Cu, and other metals. Scanning electron microscopy analysis suggests that hydrozincite is mainly of biological origin. Dormant photosynthetic microorganisms have been retrieved from 1-year-old dry hydrozincite. The autofluorescent microorganisms were imaged by a scanning confocal laser microscope. A photosynthetic filamentous bacterium, classified asScytonema sp. strain ING-1, was found associated with microalga Chlorella sp. strain SA1. This microbial community is responsible for the natural polishing of heavy metals in the water stream by coprecipitation with hydrozincite.

Schoenoplectus californicus subsp. tatora (totora) is an endemic plant from wetlands in South America’s Altiplano region. In the endorheic Titicaca-Desaguadero-Poopó-Salar de Coipasa system (TDPS), totora can be found along rivers, lakes, and shallow ponds. Lake Uru-Uru is a minor lake placed upstream of Lake Poopó, and it gets water inflows from the Desaguadero River, the city of Oruro and several mining and metallurgic complexes. Polluted waters from these origins, together with natural high salinity and high presence of As and Pb, make Lake Uru-Uru an ideal location to search for plant species suitable to be used in constructed and restored wetlands under pollution stress, particularly in systems with high pH and salty waters. To test if totora could meet such requirements, healthy plants were collected at two sites in Lake Uru-Uru with different exposure to polluted inflows. Chemical composition of different organs (leaves, rhizomes and roots) were compared. Results indicated totora’s capacity to withstand high concentrations of a cocktail of multiple pollutants and heavy metals. Particularly, this research showed totora as a multi-hyperaccumulator (concentrations in shoots higher than 1000 mg kg−1) for As, Fe and Ni. These results, combined with totora’s intrinsic high rates of biomass production, slow decomposition rates and its value as raw material for local craftwork and industrial uses, support the recommendation to use totora in constructed or restored wetlands, particularly in sites polluted with heavy metals, and in waters with high salinity.

Abstract During the summer of 1994, we compared the physical and nutrient characteristics of the three main tributaries of Cootes Paradise: Spencer, Chedoke and Borer’s creeks. On all sampling occasions, concentrations of CHL α and nutrients were always lowest in Borer’s Creek and highest in Chedoke Creek. There were generally 10-fold higher CHL α concentrations and 2 to 10 times higher levels of nitrogen and phosphorus in Chedoke Creek compared with Spencer Creek. Despite this, the light environment did not differ significantly between Spencer and Chedoke creeks because the low algal biomass in Spencer Creek was balanced by a relatively high loading of inorganic sediments from the watershed. Laboratory experiments indicated that sediments from Chedoke Creek released up to 10 µg/g of soluble phosphorus per gram (dry weight) of sediment, compared with only 2 µg/g from Spencer Creek. By contrast, sediment samples from Spencer Creek contained levels of polycyclic aromatic hydrocarbon that were as high as or higher than those from Chedoke Creek, and much higher than those found in Borer’s Creek. The distribution of normalized PAH concentrations suggests a common source of PAHs in all three tributaries, most likely automobile exhaust, since there were high concentrations of fluoranthene and pyrene, both of which are derivatives of engine combustion.

The impact of the urban effluents of Mytilene (Lesvos island, Greece) on the receiving coastal marine environment, was evaluated by studying the quality of the city effluents (BOD5, COD, SS, heavy metals) and the marine sediments (grain size, organic matter, heavy metals). It was found that the urban effluents of Mytilene contain high organic matter and suspended particle load because of septage discharge into the sewerage network. Furthermore, although the city does not host important industrial activity, its effluents contain appreciable metal load, which is mainly associated with the particulate phase. The city effluents are discharged into the coastal marine environment and their colloidal and particulate matter after flocculation settles to the bottom, where is incorporated into the sediments. Over the years, the accumulation of organic matter and metals into the harbour mud has created a non-point pollution source in the relatively non-polluted coastal marine environment of the island. Copper and Zn were the metals which presented the higher enrichment in the sediments of the inner harbour of Mytilene.

The aim of this work was to evaluate the potential of ultrasound (US), alone or in combination with mild heating and/or EDTA towards reduction of As, Cd, I, and Hg content of Laminaria hyperborea. Concentrations of As, Cd, I, and Hg of 56.29, 0.596, 7340, and <0.01 mg kg−1 of dry weight, respectively, were found in L. hyperborea blades. Treatment with US at 50 °C increased approx. 2-fold the amount of As released, although did not affect significantly the content of Cd or I, as compared to control (no US) samples. Reducing the temperature to 8 °C significantly decreased the effect of US, but heating at 80 °C did not cause a significant effect as compared to treatments at 50 °C. On the other hand, treatment with 0.1 N EDTA at 50 °C enhanced the percentage of Cd released by approximately 7-fold, regardless of sonication. In the present work, the combination of US and EDTA at 50 °C for 5 min led to a significant reduction of the As (32%), Cd (52%) and I (31%) content in L. hyperborea, thus improving the product’s safety for consumers.
