Plants and their components have maintained importance in human life as medicinal and aromatic ingredients that have been used by people for many centuries. Nature is the chief source of these valuable resources and humans use these plants directly after collection from their habitat. Therefore, the places where such plants grow have become highly important for understanding the role and behaviour of the accumulation of various elements, especially heavy metals. The aim of the present study was to evaluate the levels of heavy metals in Echium italicum L. plants collected from seven different locations in the province of Sivas in Northern Turkey. Heavy metal pollution was determined in the analysis of the plants. A significant difference was observed in the amounts of heavy metals between plants growing in areas with high vehicle traffic and in the plants growing in low traffic areas. This is of great importance for medical and aromatic plants, which are usually collected from areas of natural growth. Therefore, when these plants are collected from the wild, low traffic areas should be selected.

Abstract Background Heavy metal accumulation in the ecosystem constitutes a potential toxic effect which is hazardous to human health. Increasing environmental pollution has necessitated the use of cattle egrets to evaluate the levels of heavy metal contamination, to establish their use in biomonitoring of heavy metals and to provide data for monitoring pollution in the environment. Results The present study assessed the utilization of Bubulcus ibis in monitoring pollution in five abattoirs, namely Agege, Bariga, Kara, Itire and Idi-Araba, all situated in Lagos State. The concentration of five (5) heavy metals, cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn) was determined in the liver, muscle and feather of Bubulcus ibis using the atomic absorption spectrophotometer. The trend of metal accumulation was in the order: Zn > Cu > Pb > Cd > Ni for all the sampled tissues. The mean tissue concentrations of the metals were significantly different (p < 0.05) among the sites. The highest levels of metal concentration were reported in the liver in all the locations. Mean concentration of Cd in Kara (0.003 ± 0.00058) was significantly (p < 0.05) higher than those found at Agege (0.0013 ± 0.00058) and Idi-Araba (0.001 ± 0.001). A significant difference (p < 0.05) was also observed between the mean concentrations of Cu in Bariga (0.01 ± 0.001) and Idi-Araba (0.003 ± 0.001). Conclusion All the studied heavy metals were present in the liver, muscle and feathers of the cattle egrets. The contamination levels were ascertained from the study which indicated that cattle egrets are useful in biomonitoring studies and the generated data will serve as baseline data which could be compared with data from other locations for monitoring heavy metal pollution.

Euchema cottoni or Kappaphycus alvarezii is one type of seaweeds that is widely cultivated in Indonesia. Water pollution caused by the accumulation of Pb heavy metals will affect the seaweed to grow and develop. This study is aimed to determine the tannin levels in K. alvarezii and the relationship of Pb heavy metal pollution level with tannin levels in K. alvarezii in different waters. This study used an observational experiment, and samples were taken from two different locations with 4 stations in each. From each sample in both locations, K. alvarezii was taken and was then measured for the tannin levels, water quality, and heavy metals (Pb) in water and in K. alvarezii. The results were analyzed at the Laboratory of PT. Sucofindo and the Laboratory of Testing Service Unit, Airlangga University Surabaya. The data were analyzed using a statistical test in the form of a t-test to determine the differences in samples in both waters, and a C-square test was used to determine the relationship between PB and tannin levels in K. alvarezii. The results showed that the level of Pb heavy metal pollution in the two waters did not show a significant difference due to water quality which was quite similar in both locations. Moreover, the tannin content in K. alvarezii in Bluto waters (0.053±0.004%) was higher than that in Talango waters (0.020±0.009%). Meanwhile, a t-test showed a significant difference in seaweed tannins in both waters. The relationship between Pb heavy metal pollution and tannins of seaweed in Bluto and Talango waters was that they did not affect each other, and tannin concentration was more influenced by chemical oxygen demand (COD), salinity of both waters, and the cultivation methods used.

Abstract This study was conducted to calculate the burden of heavy metals i.e., aluminium (Al), arsenic (As), barium (Ba) and lead (Pb) in the river water of Punjnad Headworks, Bahawalpur, Pakistan. For this purpose, samples were collected from surface water, bed sediments and planktons during autumn, winter and spring seasons (September 2018 to May 2019). The results showed that in surface water Pb concentration was highest (453.87 mg L-1), while in sediments and plankton, Al concentration was highest (370.24 µg g-1 and 315.05 µg g-1, respectively). A significant difference (p < 0.000) in metal concentrations was found among surface water, bed sediments and plankton at different sampling stations during various seasons. However, findings of this study showed no adverse effects of heavy metal concentrations on human health. This study provided better understanding of various pollutants and their concentrations in water sources at the studied location.

Abstract. Yousif RA, Choudhary MI, Ahmed S, Ahmed Q. 2020. Review: Bioaccumulation of heavy metals in fish and other aquatic organisms from Karachi Coast, Pakistan. Nusantara Bioscience 13: 74-85. Heavy metals are being utilized in a variety of ways in industries, agriculture, food processing and household in many forms. Metals are unique environmental and industrial pollutants in the sense that they are neither created nor destroyed by human beings but are only transported and transformed into various products. The present study deals with the findings of various investigators on the effect of heavy metals on fish and other aquatic organisms on Karachi coasts of Pakistan. The polluted areas (Rivers and Karachi coasts) receiving effluents from industrial, agricultural, municipal and domestic wastes. The order of abundance of the metals were as fellow; Fe > Zn > Cu > Mn > Cd > Pb > Cr > Ni > Hg > As. Most studies showed that essential metals (Fe, Zn, Cu, and Mn) in aquatic organisms are much high, but the quantities of non-essential metals are found to be less. This review has shown that fish and other aquatic organisms are used as bio-monitoring species in heavy metal pollution. It is suggested that such investigations should be continuous in terms of both human health and determination of metal pollution in aquatic environment.

Background: Reports are available indicating that leaded gasoline is still being made available in some parts of the world. Moreover it is also known that the crude from which petroleum products are obtained is rich in heavy metals. This means heavy metal toxicity from petrol contact is a possibility. The aim of this study is to assess selected heavy metal levels in teenagers who are currently and formerly employed as GSA.Materials and Methods: The study population consisted of teenagers divided into 3 groups. GROUP I was made up of 30 male subjects that are currently employed as GSA with less than 6 months work history; GROUP II composed of 34 male teenagers with work history in gas station not less than 20 months; GROUP III consisted of 22 male teenagers who were former attendants; the control group consisted of 35 participants, with no history of occupational exposure to fuel, or heavy metals. Information was obtained through questionnaire on demography, life-style and clinical symptoms of gasoline exposure. Serum heavy metal levels were estimated using atomic absorption spectrometry. Student’s t test and analysis of variance were employed to determine the level of significant difference. P < 0.05 was considered significant.Results and Discussion: The serum levels of lead, arsenic, nickel, cadmium, and aluminium of GSA in GROUPS I and II were significantly higher compared with control. On the other hand, there were significant increases in levels of lead and cadmium in GROUP III compared with control. Additionally, majority of test subjects in GROUPS I and II identified headache and fatigue as symptoms associated with workplace. Teenage GSA are prone to heavy metal toxicity and discontinuing contact with gas station environment did not resolve this occupational hazard.Conclusion: Gonadotoxic effect of some of these elements on these categories of subjects who are within reproductive stage is possible. Therefore appropriate measure should be taken to address it.Bangladesh Journal of Medical Science Vol.17(2) 2018 p.224-229

This study was aimed to determine the molybdenum content of meadow - pasture soil between Kırıkhan and Reyhanlı in Hatay province and to determine the relations of the molybdenum content with some heavy metals in the soil. For this purpose, two different depths (0-20 and 20-40 cm) representing grassland pasture lands and 80 soil samples from 40 different points were taken. Cadmium (Cd), Cobalt (Co), Nickel (Ni), Lead (Pb), Copper (Cu), Iron (Fe), and Molybdenum (Mo) contents were determined in the soil samples. The contents of the available Cd, Co, Pb, Cu, Fe, Ni and Mo of the soil were determined by reading the 0.005 M DTPA + 0.01 M CaCl2 + 0.1 M TEA extracts in the ICP instrument. The results of the research shows that the Cd contents of the soils are between 0.01-0.32 ppm; Co contents are from 0.01 to 4.97 ppm; Ni contents 0.00 to 20.00 ppm; Pb contents 3.00-67.00 ppm; Cu contents 0.26-7.48 ppm; The Fe contents are between 4.00 and 61.00 and the Mo contents are between 0.001 and 0.064 ppm. It was determined that there are significant positive relationships between Co, Ni, Pb, Cu and Fe contents of Mo in the soil. It was also determined that there are significant positive significant relationships between Cd and Co; Co with Ni, Pb, Fe and Pb and Cu, Fe and Cu and Fe. No heavy metal pollution was found when the heavy metal contents of the regional soils were compared with the limit values.

Aims: Modern industrialization, anthropogenic and industrial activities have increased the risk of human exposure to heavy metals and in turn effecting human health badly. Hundreds of millions of people are globally affected by heavy metal toxicity through contaminated water in one way or. another. In order to find a correlation between the heavy metal concentrations and serum creatinine level, a study was conducted on the inhabitants living near the Hudiara drain suffering from kidney diseases. Study Design: The subjects (n=498) were selected from the vicinity of polluted Hudiara drain to conduct this matched case–control study in 2019-2020. Instrumental techniques were used for the determination of heavy metals and creatinine was determined by using Kit. The correlation between heavy metals and creatinine was checked. Place and Duration of Study: To determine heavy metals and creatinine in blood, samples were collected from the habitants of Hudiara drain and the control group 100Km far from Hudiara drain. Methodology: Blood samples of male subjects with and tested for heavy metals in the blood using atomic absorption spectrophotometer and creatinine level using Creatinine Elisa Kit. The study was conducted in 2020 and included n= 498 healthy volunteers (control) and n=498 effected (suffering from chronic kidney disease). Results: The ANOVA shows the significant difference between two groups i.e.  control group and affected group in all traits of the respondents (weight, age, heavy metal values and serum creatinine level). Pearson’s correlation coefficient was calculated for heavy metals and creatinine subjects’ blood samples. It was found that heavy metal levels in subjects have a significant correlation with serum creatinine. The study shows that serum creatinine level has no significant correlation with age, so is independent of age. Conclusion: The concentration of heavy metal contaminants (Cd, Hg, Pb) in the blood of the inhabitants of Hudiara drain flowing in Lahore city, Pakistan is highly polluted by industrial effluents. The effects of higher concentration of heavy metals in the inhabitants of Hudiara drain have been determined in serum creatinine levels. It was observed that high serum creatinine values are found in subjects suffering from CKD.

<div> <p>The growing number of polluted land areas makes the question of rehabilitation and safe/effective use of these areas increasingly imperative. For land polluted by heavy metals, the possibility of transferring the toxic pollutants to humans through the food chain further increases the importance of the safe management of polluted lands.&nbsp; We examined the possibility of using heavy metal-polluted areas for growing specific aromatic plants, which can be used either as food herbs/infusions, or to produce high value products. In a pot experiment, chamomile, sage and thyme plants were exposed to a range of concentrations of Cd, Pb, and Ni in the soil. Toxic metal levels were determined in the roots, leaves and flowers (for chamomile) of the plants. All three plants accumulated relatively high amounts of metals in their roots, whereas the aboveground parts exhibited lower accumulation capacity. Regardless the levels of metal accumulation, the quality of essential oils from chamomile, sage, and thyme was not affected and in all cases the extracted essential oils were free of heavy metals. Our results suggest that the aromatic plants under study cannot be consumed either as food additives or as infusions. However, under strict control of the cultivations, heavy metal-contaminated areas can be used for the production of essential oils from aromatic plants.</p> </div> <p>&nbsp;</p>

Abstract The concentrations of zinc, copper, lead and nickel in the Penang River and its tributaries were determined to assess the extent of heavy metal pollution, and to evaluate which compartment provides a better indicator for heavy metal pollution. The results indicate that the concentrations of total and non-residual heavy metals in sediments increase significantly towards the estuary of the river. This trend is, however, not obvious for heavy metals in the river water. The data indicate that assessment of heavy metal pollution in rivers could be made by using the data of heavy metal levels in river sediments. It is suggested that non-residual heavy metal levels in sediments give the best indication of anthropogenic input of heavy metals to river systems.
