Heavy metal pollution has been a source of health problems in humans. These metals are persistent, toxic, non-degradable and often take a long time to be eliminated from the body. This study is, therefore, designed to assess heavy metal pollution of River Basin in Nigeria. Seventy stream sediment samples were systematically collected from an area, approximately 400km2, latitude 7O 00’ and 7O 15’N and longitude 5O 11’ and 5O 19’E. The pollution status of the sediments by heavy metals were assessed by Enrichment Factor (EF), Pollution Load Index (PLI) and Geo-accumulation Index (Igeo). The concentrations of the heavy metals were also compared with United States Environmental Protection Agency (USEPA) Sediment quality guidelines (SQG). The samples were dried in the laboratory, disaggregated, sieved to minus 80 (<177 microns) mesh size using nylon sieve. The sieved samples were, then, digested and the concentrations of As, Co, Fe, Mn, Ni, Pb, V and Zn were determined by Wavelength Dispersive X-ray Fluorescence Spectrometry (WD-XRFS). Results revealed that the mean concentrations of the heavy metals are in the order V>Zn>Pb>As>Ni>Co>Fe>Mn. Furthermore, the mean concentration of lead exceeded both the average world shale and the USEPA SQG values. However, the mean concentration of cobalt, nickel, manganese and zinc were lower than the average world shale values for these elements. The Enrichment Factor (EF) revealed that cobalt was moderately enriched while arsenic and lead were significantly enriched in the sediments. On the basis of the geoaccumulation index, the stream sediments were largely uncontaminated except at some sites that were moderately to strongly contaminated by As and Pb.

The Impact

The farmland soils around three typical livestock farms in Jilin province were studied to elucidate the impact of farms on heavy metal pollution in surrounding farmland soils. The results showed that the average content of Cd was maximal in the soils around cattle farm (0.29 mg kg-1); the average value of Pb was highest in the soils around the pig farm; and Cu, Zn, Ni and Cr were all highest in the soils around the chicken farm. The distribution of heavy metals in the soils around different livestock farms varied greatly. The contents of Cu, Zn, Ni and Cr decreased in the same order: chicken farm> pig farm > cattle farm, but Pb was pig farm> chicken farm> cattle farm, and Cd was cattle farm> pig farm> chicken farm. These results indicated that the livestock farms did not cause significant heavy metal pollution in its surrounding agricultural soils, but the accumulation of heavy metals caused by farms should arouse the attention.

Nitric Acid Digestion

Cosmetics production and use are growing worldwide, yet users are concerned about toxicity and heavy metal pollution. Following nitric acid digestion, the estimated levels of lead (Pb), nickel (Ni), chromium (Cr), cadmium (Cd), arsenic (As), mercury (Hg), titanium (Ti), iron (Fe), and cobalt (Co), in 6 brands of lipstick (12 samples) obtained in the Saudi market have been computed by inductively coupled plasma optical emission spectroscopy. Correlation coefficients (R2) varied from 0.9992 to 0.9999 on the calibration curve, indicating good linearity. Except for low-cost specimens, the findings indicate that the concentrations of the metals under investigation are often lower than the acceptable limits of both the Saudi Standards, Metrology, and Quality Organization (SASO) and the Food and Drug Administration (FDA) (which revealed the maximum lead levels of 125.30 ppm, exceeding the allowed limit of 10 ppm). Arsenic was discovered in significant concentrations, exceeding the SASO permitted limit. Nickel was found at the FDAs allowable limit; chromium and cobalt were found in variable quantities in the majority of the specimens. Dark-colored lipstick had a greater overall content of heavy metals than light-colored lipstick. Numerous tests on SASO-approved lipsticks were conducted as part of the research. The lower-cost specimens were of lesser quality, failing some SASO tests. All such findings suggest that users should be cautious when buying low lipsticks since heavy metals may build up in the body over time, causing skin problems or diseases like cancer.

The Impact

AbstractPreservation of the soil resources stability is of paramount importance for the ecosystem, particularly in the current era of environmental change, which presents a severe pollution burden (e.g. by heavy metals) to soil ecosystems and its fauna. Gut microbiomes are becoming recognized as important players in organism health, with comprehension of their perturbations in the polluted environment offering new insights into the nature and extent of heavy metal effects on the health of soil biota. Our aim was therefore to evaluate the effect of environmentally relevant heavy metal concentrations of cadmium (Cd) on the earthworm gut microbiota. Cd exposure led to perturbations of several heavy metal resistant taxa as well as taxa able to bind heavy metals, revealing the potential of the earthworm-microbiota system in overcoming humancaused heavy metal pollution. An ‘indicator species analysis’ linked bacterial generaPaenibacillusandFlavobacterium, and members of the order Actinomycetales with Cd treatment, suggesting the possible use of these bacterial taxa as biomarkers of exposure for Cd stressed soils. The results of this study will be essential to understanding of the soil fauna health, under anthropogenic disturbance, and will have implications for environmental monitoring and protection of soil resources.ImportanceSoil heavy metal pollution presents a severe burden for soil invertebrates and can have impact on their health, which in turn reflects on the health of the entire ecosystem. Gut microbiome is recognized as a central driver of the host health and its shifts can have severe consequences for the host. In this study we investigated the impact of cadmium (Cd) on earthworm gut microbiota, in a controlled experiment using cutting edge next generation sequencing and state of the art bioinformatics tools. The significance of this study is in identifying the gut bacterial taxa which are indicators for Cd treatment and are potential biomarkers of exposure to Cd. Therefore, this study contributes to develop efficient measures to qualify environmental pollution and to protect fragile soil resources and ultimately human health.

Purpose. This paper aims to reflect the extent of the impact of the Artana mine on heavy metal pollution of the waters of the Marec river. Mineralogical pollution of this river resulted in almost total degradation of biota. Methods. To be as realistic as possible in assessing the water quality of the Marec river and of a single spring located in the research area and used for drinking, we have applied the standard methods ISO 5667-6 for surface water and ISO 5667-11 for groundwater. The sampling and the quantity of the samples, as well as their transportation, was done in full compliance with the ISO 5667-1.3 method. Whereas, the conservation of samples taken for the determination of heavy metals is done according to the APHA conservation procedure. For the extraction (mineralization) of heavy metals in the samples taken, the EPA-3015A method was applied, while for the determination of the concentration of heavy metals the SAA (Atomic Absorption Spectrophotometry) measurement technique was applied. Findings. As a result of the industrial activity of the Artana mine, it has been ascertained that the main causes of the pollution of the Marec river waters and the habitat around it is the mineral exploitation activity in this industrial complex. Analysis of water samples discharged from the mine, flotation and drainage of landfills reflect the real state of heavy metals concentration in the Marec river. Originality. In order for the results to realistically reflect the degree of heavy metals concentration in the waters of this river, we have implemented existing and advanced analytical techniques. Practical implications. The water samples from the Marec river were taken and analyzed in January and July 2020. The analysis performed showed significant exceedance of heavy metals concentration in all sampling sites located in the studied industrial area.

Abstract Background Heavy metal pollution of aquatic systems is a global issue that has received considerable attention. Canonical correlation analysis (CCA), principal component analysis (PCA), and potential ecological risk index (PERI) have been applied to heavy metal data to trace potential factors, identify regional differences, and evaluate ecological risks. Sediment cores of 200 cm in depth were taken using a drilling platform at 10 sampling sites along the Xihe River, an urban river located in western Shenyang City, China. Then they were divided into 10 layers (20 cm each layer). The concentrations of the As, Cd, Cr, Cu, Hg, Ni, Pb and Zn were measured for each layer. Eight heavy metals, namely Pb, Zn, As, Cd, Cr, Cu, Ni, and Hg, were measured for each layer in this study. Results The average concentrations of the As, Cd, Cu, Hg, and Zn were significantly higher than their background values in soils in the region, and mainly gathered at 0–120 cm in depth in the upstream, 0–60 cm in the midstream, and 0–20 cm downstream. This indicated that these heavy metals were derived from the upstream areas where a large quantity of effluents from the wastewater treatment plants enter the river. Ni, Pb, and Cr were close or slightly higher than their background values. The decreasing order of the average concentration of Cd was upstream > midstream > downstream, so were Cr, Cu, Ni and Zn. The highest concentration of As was midstream, followed by upstream and then downstream, which was different to Cd. The potential factors of heavy metal pollution were Cd, Cu, Hg, Zn, and As, especially Cd and Hg with the high ecological risks. The ecological risk levels of all heavy metals were much higher in the upstream than the midstream and downstream. Conclusions Industrial discharge was the dominant source for eight heavy metals in the surveyed area, and rural domestic sewage has a stronger influence on the Hg pollution than industrial pollutants. These findings indicate that effective management strategies for sewage discharge should be developed to protect the environmental quality of urban rivers.

Pollution Indices

It is a well–known fact that heavy metal pollution in sediments causes serious problems not only in the Danube basin, but also in the large and small adjacent river streams. A suitable method for assessing the level of heavy metals and their toxicity in sediments is the calculation of pollution indices. The present research aims to assess heavy metal pollution in the Lower Danube surface sediments collected along the Danube course (between 180 and 60 km) up to the point where the Danube River flows into the Danube Delta Biosphere Reserve (a United Nations Educational, Scientific and Cultural Organization – UNESCO, protected area). In addition, this monitored area is one of the largest European hydrographic basins. Five heavy metals (Cd, Ni, Zn, Pb, Cu) were analyzed in two different seasons, i.e., the autumn of 2018 and the spring of 2019, using the Inductively Coupled Plasma Mass Spectrometry (ICP– MS) technique. Our assessment of heavy metal pollution revealed two correlated aspects: 1. a determination of the potential risks of heavy metals in sediments by calculating the Potential Ecological Risk Index (RI), and 2. an evaluation of the influence of anthropogenic activities on the level of heavy metal contamination in the surface sediments, using three specific pollution indices, namely, the Geo–Accumulation Index (Igeo), the Contamination Factor (CF), and the Pollution Load Index (PLI). The results of this pioneering research activity in the region highlighted the presence of moderate metal (Ni and Cd) pollution and a low potential ecological risk for the aquatic environment.

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.
