Risks Assessment

Rainwater samples were collected in Jengka, Pahang Malaysia. Temperature, pH, TDS, EC, Al, Cu, Mn, and Zn were measured. The concentrations of heavy metals (Al, Cu, Mn and Zn) in thirty-eight samples were analysed using inductively coupled plasma-mass spectrometry (ICP-MS). Statistical analysis results indicate that pH, TDS, and EC showed significant differences between wet and dry seasons. However, no significant difference was observed seasonally for heavy metals (HMs). All parameters, except pH, were below the Malaysian Drinking Water Guidelines (MDWG) value and the health risk assessment for HMs indicates the safe levels. Principal component analysis (PCA) suggests that HMs in rainwater in Jengka, Pahang were originated from natural and anthropogenic sources.

The research cared out to calculate the heavy metals deposition for the soil of the Blue Nile along the edges of two sides, starting from the Sudan Ethiopia border end to the Khartoum state in Tuti Island. The samples were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) technique. The results show that there is a significant difference for most of the concentration of the elements deposition on two sides of the Blue Nile outside of Nile channel for that area which covered by water after the overflow. Heavy metals Cr, Fe, Co, Cu, and Zn concentration deposition are increased in the direction of the water to Khartoum, while Ni and Pb concentrations are decreased in the same direction. K, Ca, Ti, Mn, Br, Rb, Sr, and Zr heavy metal concentrations are varied but in general remains equals.

Multifloral Honey

The substantial of mineral ingredients in honey may symbolize the existence of elements in the plants and soil of the vicinity wherein the honey was taken. The aim of this study was to detect the levels of 13 elements (Potassium (K), Sodium (Na), Calcium (Ca), Iron (Fe), Zinc (Zn), Cadmium (Cd), Copper (Cu), Manganese (Mn), Lead (Pb), Nickel (Ni), Chromium (Cr), Aluminum (Al), and Selenium (Se)) in unifloral and multifloral honey samples from south and east regions of Turkey. Survey of 71 honey samples from seven different herbal origins, picked up from the south and east region of Turkey, was carried out to determine their mineral contents during 2015-2016. The mineral contents were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The most abundant minerals were K, Na, and Ca ranging within 1.18–268 ppm, 0.57–13.1 ppm, and 0.77–4.5 ppm, respectively. Zn and Cu were the most abundant trace element while Pb, Cd, Ni, and Cr were the lowest heavy metals in the honey samples surveyed, with regard to the concentrations of heavy metals such as Zn, Cu, Pb, Cd, Ni, and Cr suggested and influence of the botanical origin of element composition. Geochemical and geographical differences are probably related to the variations of the chemical components of honey samples.

Henna and walnut tree bark are widely used by Libyan women as cosmetics. They may contain lead (Pb), cadmium (Cd) and arsenic (As), which, in turn, pose a high risk to their health. This study aims to determine the levels of Pb, Cd and As in henna and walnut tree bark products sold in Libyan markets. The products were analyzed for their Pb, Cd and As content by using inductively coupled plasma mass spectrometry (ICP-MS) after a microwave acid digestion. The results showed a significant difference between the henna and walnut tree bark samples in terms of their heavy metals content (p < 0.05). The highest heavy metal concentrations were observed in the walnut tree bark samples whereas the lowest was observed in the henna samples. In addition, 60% of the henna and 90% of the walnut tree bark samples contained Pb levels and approximately 80% of the henna and 90% the walnut tree bark samples contained Cd levels, which are much higher than the tolerance limit. However, As concentrations in all the samples were lower. The results indicated that such cosmetics expose consumers to high levels of Pb and Cd and hence, to potential health risks. Thus, studying the sources and effects of heavy metals in such cosmetics is strongly recommended.

Background and Objectives: In this article, a comprehensive study was carried out for food authenticity evaluation through chemometric analyses, correlating botanical and geographical origins with food chemical composition. Methods: A total of eighteen Calabrian red, rose and white wines were analyzed through Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Results: The mineral concentrations, determined by ICP-MS in the investigated wine samples, followed the subsequent order: K > P > Mg > Na > Ca > Fe > Cu > Zn > Mn > V. : The 2D Scatterplot and loading plot (Principal Component Analysis) showed that all red, rose and white wine samples from “Cirò” DOP area were grouped in the fourth, second and third quadrant, respectively, clearly separated from each other. Samples from “Cirò” red showed positive PC1 and were characterized by higher K, Fe, Mn, Na, V and Zn concentrations. Moreover, the points corresponding to two red wines from the “Terre di Cosenza” DOP area fall into the first quadrant; those corresponding to two rose wines from the “Donnici” and “Sant’Anna di Isola di Capo Rizzuto” DOP areas fall into the third and fourth quadrants, respectively; the point corresponding to a white wine from the “Donnici” DOP area falls into the second quadrant. Conclusions: Experimental results demonstrated that it is possible to strictly relate, through the PCA, wines to their geographical and botanical provenance, thus becoming a useful tool for evaluating the product authenticity and guaranteeing it to the consumers.

This review gives insights into the levels of metals in urban dust, their determination methods, and risk assessment. Urban dust harbors a number of pollutants, including heavy metals. There are various methods used for the sampling of urban dust for heavy-metal analysis and source-apportionment purposes, with the predominant one being the use of plastic sampling materials to avoid prior contamination. There are also various methods for the determination of metals, which include: atomic absorption spectroscopy (AAS) and inductively coupled plasma-mass spectrometry (ICP-MS), among others. Studies have shown that pollutants in urban dust are mainly derived from industrial activities and coal combustion, whereas traffic emissions are also an important, but not a predominant source of pollution. The varying particle-size distribution of urban dust and its large surface area makes it easier for the deposition and transport of heavy metals. Risk-assessment studies have shown that metals in urban dust could cause such problems as human pulmonary toxicity and reduction of invertebrate populations. The risk levels seem to be higher in children than adults, as some studies have shown. It is therefore important that studies on metals in urban dust should always incorporate risk assessment as one of the main issues.

Objective. To investigate the influence of gut microbiota on arsenic accumulation of realgar in mice. Methods. Mice were treated with antibiotics to form a mouse model of gut microbial disruption. Antibiotic-treated and normally raised mice were given 15 mg/kg, 150 mg/kg, and 750 mg/kg realgar by gavage and 0.2 mg/kg and 1 mg/kg arsenic solution by subcutaneous injection for 7 days. The concentration of arsenic in mice whole blood was determined by inductively coupled plasma mass spectrometry (ICP-MS). Arsenic accumulation in antibiotic-treated mice and normally raised mice was compared. Results. After exposure to low dose (15 mg/kg) and middle dose (150 mg/kg) of realgar, significantly, more arsenic was accumulated in the whole blood of antibiotic-treated mice compared to normally raised counterparts, which indicated that the disruption of gut microbiota could lead to higher arsenic load of realgar in mice. The homeostasis of gut microbiota was supposed to be disrupted by high dose (750 mg/kg) of realgar because after exposure to high dose of realgar, there was no significant difference in arsenic accumulation between antibiotic-treated and normally raised mice. Furthermore, arsenic solution was administered by subcutaneous injection to mice to investigate the influence of gut microbial differences on arsenic accumulation in addition to the absorption process, and there was no significant difference in arsenic accumulation between mice with these two different statuses of gut microbiota. Conclusions. Gut microbiota disruption could increase arsenic accumulation of realgar in mice.

: Wine is an alcoholic drink, largely used to accompany food, with a key role in the protective effects on cardiovascular diseases. This study was developed to investigate radioisotopes and heavy metal content of twenty red, rose and white Italian wines, belonging to controlled origin denomination (DOC) geographic areas of the Calabria region, south of Italy. High Purity Germanium (HPGe) Gamma Spectrometry was employed to evaluate anthropogenic (137Cs) and natural (40K) radionuclides specific activity. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used to assess any possible heavy metals contamination by a comparison between Cu, Zn, Pb, B, As and Cd concentrations with the limits set by the Italian Legislation. Calculated annual effective doses due to the ingestion of investigated samples are under allowable levels (1 mSv/year), thus excluding the risk of ionizing radiation effects on humans. Regarding to the metals concentration, experimental results show that they are lower than the contamination threshold values, thus excluding their presence as pollutants.

A number of ninety-six hair samples from Sicilian fishermen were examined for total mercury detection by an Inductively Coupled Plasma Mass Spectrometry (ICP-MS) method. The mercury levels obtained were compared with mercury levels of 96 hair samples from a control group, in order to assess potential exposure to heavy metals of Sicilian fishermen due to fish consumption and closeness to industrial activities. Furthermore, the mercury levels obtained from hair samples were sorted by sampling area in order to verify the possible risks linked to the different locations. The overall mean concentration in the hair of the population of fishermen was6.45±7.03 μg g−1, with a highest value in a fisherman of Sciacca (16.48 μg g−1). Hair mercury concentration in fishermen group was significantly higher than in control group (p<0.01). There was no significant difference in hair total mercury concentrations between sampling areas (p>0.05). The results of this study indicate a greater risk of exposure to mercury in Sicilian fishermen, in comparison to the control population, due to the high consumption of fish and the close relationship with sources of exposure (ports, dumps, etc.).
