This study was undertaken in order to determine heavy metal contents in twelve (n=12) henna brands and eleven (n=11) kohl products. An analytical test was performed for Pb, Cd, Cu, and Zn in henna and kohl products using atomic absorption spectrophotometery. The overall mean concentrations of heavy metals in henna varied between 1.2 and 8.9 μg g−1 for Pb; 0.8 and 18.6 μg g−1 for Cd; 0.5 μg g−1 and 3.3 μg g−1 for Cu; and 3.7 μg g−1 and 90.0 μg g−1 for Zn. As for kohl products, Pb concentrations ranged between 51.1 μg g−1 and 4839.5 μg g−1, Cd concentrations ranged between 1.0 μg g−1 and 158.6 μg g−1, Cu concentrations ranged between 2.5 μg g−1 and 162.5 μg g−1, and Zn concentrations ranged between 0.7 μg g−1 and 185.0 μg g−1. The results of our study revealed that Pb, Cd, Cu, and Zn contents in investigated samples were high, making from the prolonged use of such products a potential threat to human health. Therefore, major quality controls are recommended in order to enforce acceptable limits of potential contaminants in cosmetics and good manufacturing practice.

Heavy metals are released into the water system through various natural processes and anthropogenic activities, thus indirectly or directly endangering human health. The distribution, source, water quality and health risk assessment of dissolved heavy metals (V, Mn, Fe, Co, Ni, Zn, As, Mo, Sb) in major rivers in Wuhan were analyzed by correlation analysis (CA), principal component analysis (PCA), heavy metal pollution index (HPI), hazard index (HI) and carcinogenic risk (CR). The results showed that the spatial variability of heavy metal contents was pronounced. PCA and CA results indicated that natural sources controlled Mn, Fe, Co, Ni and Mo, and industrial emissions were the dominant factor for V, Zn and Sb, while As was mainly from the mixed input of urban and agricultural activities. According to the heavy metal pollution index (HPI, ranging from 23.74 to 184.0) analysis, it should be noted that As and Sb contribute most of the HPI values. The health risk assessment using HI and CR showed that V and Sb might have a potential non-carcinogenic risk and As might have a potential carcinogenic risk to adults and children in the study area (CR value exceeded target risk 10−4). At the same time, it was worth noting that As might have a potential non-carcinogenic risk for children around QLR (HI value exceeded the threshold value 1). The secular variation of As and Sb should be monitor in high-risk areas. The results of this study can provide important data for improving water resources management efficiency and heavy metal pollution prevention in Wuhan.

In this study, heavy metal content (Cu, Fe, Mn, Ni, Pb, Zn) was determined in soils and different organs of Verbascum olympicum Boiss. This species is endemic to Uludağ and spreads on destroyed areas such as: roadsides, developed building areas, ski lift stations and sheep folds. Soils and different organs (roots, stems, leaves and flowers) of plant samples were analyzed using an atomic absorption spectrophotometer for determining the element content. Heavy metal contents in soils and different organs in this species were highly correlated (P < 0.05). However, the contribution of plant organs to the accumulation capacity varied according to the metal. These results suggest that this species may be useful as a bioindicator for heavy metals.

Background. The rise in particulate matter (PM) concentrations is a serious problem for the environment. Heavy metals associated with PM10, PM2.5, and road dust adversely affect human health. Different methods have been used to assess heavy metal contamination in PM10, PM2.5, and road dust and source apportionment of these heavy metals. These assessment tools utilize pollution indices and health risk assessment models. Objectives. The present study evaluates the total mass and average concentrations of heavy metals in PM10, PM2.5, and road dust along selected road networks in Dhanbad, India, analyzes the source apportionment of heavy metals, and assesses associated human health risks. Methods. A total of 112 PM samples and 21 road dust samples were collected from six stations and one background site in Dhanbad, India from December 2015 to February 2016, and were analyzed for heavy metals (iron (Fe), lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), chromium (Cr), and zinc (Zn)) using atomic absorption spectrophotometry. Source apportionment was determined using principal component analysis. A health risk assessment of heavy metal concentrations in PM10, PM2.5, and road dust was also performed. Results. The average mass concentration was found to be 229.54±118.40 μg m−3 for PM10 and 129.73 ±61.74 μg m−3 for PM2.5. The average concentration of heavy metals was found to be higher in PM2.5 than PM10. The pollution load index value of PM10 and PM2.5 road dust was found to be in the deteriorating category. Vehicles were the major source of pollution. The non-carcinogenic effects on children and adults were found to be within acceptable limits. The heavy metals present in PM and road dust posed a health risk in the order of road dust&gt; PM10&gt; and PM2.5. Particulate matter posed higher health risks than road dust due to particle size. Conclusions. The mass concentration analysis indicates serious PM10 and PM2.5 contamination in the study area. Vehicle traffic was the major source of heavy metals in PM10, PM2.5, and road dust. In terms of non-carcinogenic risks posed by heavy metals in the present study, children were more affected than adults. The carcinogenic risk posed by the heavy metals was negligible.

In the present study, a risk assessment of pesticides, phthalates and heavy metals in strawberries (n = 335) in recent years was conducted by determining the out estimate dietary intake (EDI), target hazard quotient (THQ) and hazard index (HI) . 128 Pesticides, 18 phthalates and 3 heavy metals were determined in this determination. 51 pesticide residues were detected in the strawberry samples, and 97.91% samples had levels of at least one of the 51 pesticides above the LOD (limit of detection). 2.39% of samples had pesticides higher than the Chinese MRL. Multiple pesticides residues were detected in most samples. Bis-2-ethylhexyl phthalate (DEHP), diisobutyl phthalate (DIBP) and dibutyl phthalate (DBP) were detected in the strawberry samples with high frequency of detection. Their detectable rates were 100, 100 and 89.9%, respectively. Most of the samples were detected lead (Pb), cadmium (Cd) and nickel (Ni) with the detectable rates 75.76, 92.93 and 92.93%, respectively. Estimated daily intake of analyzed pesticide, phthalate and heavy metal residues appear to be relatively low compared to the ADI. The average THQs and HI were less than one. That means the customers who are exposed to the average contaminants levels may not pose significant health risk. Our results show that the strawberries may be polluted by many kinds of contaminants. Therefore, monitoring of pesticides, phthalates and heavy metal residues in strawberries should be increasingly developed in order to fully protect the health of the consumer.

Food crops grown in contaminated soils have a greater accumulation of heavy metals and the consumption of food crops grown in the contaminated soils are the source of metals that enters into the human body. Rice being a major food crop, the presence of heavy metals should be monitored regularly for reducing health risk. The analysis of total heavy metal always overestimates the content which leads to misinterpretation of results; however, bioaccessible heavy metal analysis projects the actual health risk. Hence, the present study aims to assess the bioavailable form of heavy metals in rice. The rice samples were collected from 20 different places and used for the inherent and bioavailable metal estimation. In vitro simulated digestion method was applied for bioaccessible metal analysis. Metal concentration in polished rice ranged from 0.10 to 0.82, 0.10 to 1.07, 0.11 to 0.56 and 0.23 to 1.09 mg kg-1 for Lead (Pb), Nickel (Ni), Cadmium (Cd) and Chromium (Cr), respectively. Twenty five percent of the samples recorded less than 0.028, 0.01, 0.01, and 0.03 mg kg-1 of bioaccessible Pb, Ni, Cd, and Cr, respectively. A significant negative correlation was observed between total metal concentration and bioaccessibility percentage. Targeted Hazard Quotient (THQ) of all the metals were less than one for adults indicating that there were no health risks, which undoubtedly reveals the importance of bioaccessible metal analysis. Hence, regular monitoring of heavy metals is essential to reduce the intensive accumulation in the human food chain. Also, the present study has opened up a wide scope on human health risk assessment using an in vitro digestion model.

Heavy metals may cause acute and chronic toxic effects to humans and other organisms, hence the need to treat wastewater properly, as it contains these toxicants. This work aimed at assessing zinc, copper, cadmium, and chromium in water, soil, and plants that are irrigated with effluent from Manase and Soche Wastewater Treatment Plants (WWTPs) in Blantyre, Malawi. Atomic Absorption Spectrophotometry (AAS) was used to assess the heavy metals. Heavy Metal Health Risk Assessment (HMHRA) on plants (vegetables) around both WWTPs was also conducted. Average daily dose (ADD) and target hazard quotients (THQ) were used to assess HMHRA. Physicochemical parameters were determined using standard methods from American Public Health Association (APHA). The heavy metal ranges were below detection limit (BDL) to 6.94 mg/L in water, 0.0003 to 4.48 mg/kg in soil, and 3 to 32 mg/L in plants. The results revealed that plants irrigated with effluent from WWTP had high values of aforementioned metals exceeding the Malawi Standards and WHO permissible limits. Furthermore, the health risk assessment values showed that vegetables consumed for a long period of time from Manase WWTP were likely to cause adverse health effects as compared to those from Soche WWTP.
