In this study, the atomic absorption spectrophotometer (AAS) technique has been used in analysing 26 soil samples for five heavy metals: Pb2+, Cu2+, Zn2+, Cr3+ and Ni2+ in Zakho district, Kurdistan region - Iraq. Heavy metals can be accrued to the soil during the releases of industrial waste, removal of extraordinary quality metal waste, petrochemical falls and etc. In all soil samples, heavy metals concentration was found in the range of 0.541 - 4.339 mg/L for Pb, 0.118 - 0.797 mg/L for Cu, 1.260 - 5.540  mg/L for Zn, 1.315 - 2.102 mg/L for Cr and 1.049 -1.635 mg/L for Ni. As shown in the result, the heavy metals concentration contents increases with fossil fuel combustion, industrial releases, and agricultural activities. However, the results of the AAS technique was found that the high concentration element Pb and Zn were determined than the other elements like Cu, Cr and Ni but less than acceptable limits in all cases. Regarding to achieve data in the recent research, soil of case study can be relatively considered unpolluted, healthy and it is suitable for growth plants and usable for other purposes.

STUDI PENURUNAN KADAR LOGAM BESI (Fe) DAN LOGAM TEMBAGA (Cu) PADA AIR EMBUNG MENGGUNAKAN ADSORBEN NANOSILIKAABSTRAKPolusi limbah logam berat dalam air merupakan satu permasalahan lingkungan yang penting. Dalam mengatasi permasalahan tersebut dapat dilakukan purifikasi terhadap air tersebut. Metode yang dapat digunakan untuk purifikasi limbah sangat beragam salah satunya adalah absorpsi. Secara umum metode absorpsi telah banyak digunakan dalam purifikasi air limbah. Metode absorpsi dapat menurunkan kadar logam yang terlarut pada limbah. cair dengan cara menyerap logam-logam tersebut ke dalam permukaan absorbennya. Tujuan dilakukan penelitian ini adalah  untuk menurunkan konsentrasi logam besi (Fe) dan tembaga (Cu) menggunakan adsorben nanosilika. Penelitian ini menggunakan variabel bebas yaitu waktu pengadukan (20 menit, 40 menit, dan 60 menit). Hasil akhir filtrat air embung kemudian diukur absorbansinya menggunakan Spektrofotometer Serapan Atom. Berdasarkan hasil analisa menggunakan instrumen SSA diperoleh hasil bahwa tidak terjadi penurunan logam Fe maupun Cu. Dalam hal ini terjadi peningkatan konsentrasi dalam logam Fe maupun Cu, hal ini dikarenakan kurangnya waktu pengadukan dan pengaruh dari adsorben nanosilika.Kata Kunci: limbah, logam berat, nanosilika STUDY OF DECREASING METALS IRON (Fe) AND COPPER (Cu) ON EMBUNG WATER USE OF NANOSILICA ADSORBEN ABSTRACTHeavy waste pollution of heavy metals in the water is an important environment issue. To solve the problem, its can be purified the water. The methods that can be used for waste purification are very diverse, one of which is absorption. In general, the method of absorption has been widely used in wastewater purification. The absorption method can decrease dissolved metal content in the waste. liquid by absorbing the metals into the absorbent surface. Research has been conducted to reduce the concentration of iron (Fe) and copper (Cu) by using nanosilica adsorbent. This research used to independent variable that is stirring time (20 minutes, 40 minutes, and 60 minutes). The final result of filtrate embung water then measured its absorbance using Atomic Absorption Spectrophotometer (AAS). Based on the result of the analysis using SSA instrument, it is found that there is no decrease of Fe and Cu metals. There are several reasons for those problem such as due to lack of stirring time and the influence of nanosilica adsorbent.Keywords: Waste pollution, heavy metal, nanosilica

Abstract The study is focused on environmental assessments of impacts by former briquette factory at the Nagymányok area in South Hungary. The (former) industrial zone is located in a northern valley of the Eastern Mecsek Mountains. Until the 1990s this company was the largest briquette factory in Hungary and the demolition works are still incomplete. former investigations were based on only five samples. our sampling sites were selected on the basis of the source of the contaminations and then we covered the whole area in equal distribution. We used the A1-F6 codes for the sample places. We have started from southwest to northeast. The samples were analyzed for Total Petrol Hydrocarbons (TPHs), Polycyclic Aromatic Hydrocarbons (PAHs) and for heavy metals. The area was heavily contaminated by TPHs and moderately heavy metals (such as Cu, Cr, Zn and Pb). Highest contaminant concentrations were found around the former industrial buildings, especially between the boiler-house and the coal-pillbox. In the industrial area the mean of the detected values is below the upper limit of the legal exposure values, but among the former industrial buildings higher (e.g. toxic level) concentration values were detected in multiple samples. Based on our investigation the pollutant can be transported by wind or by water on the surface (stream bed) or underground. The hazardous material can easily reach some part of the city, therefore reclamation is necesarry.

Differences in the accumulation of heavy metals lead and cadmium in water, sediments and mangrove organs (roots, stems and leaves) found in the waters of Tulehu, Maluku Province. Samples were taken from three observation stations, namely stopping ships that are not operating (station 1), Tulehu harbor (station 2) and Control (station 3). Pb and Cd were analyzed using Atomic Absorption Spectrophotometer. Pb and Cd content in sediments is higher than in water. The highest Pb and Cd content is found in the stems then in the roots and leaves (stems> roots> leaves). Mangroves are one of the aquatic organisms that have the ability to absorb heavy metals in the aquatic environment. Key words: Mangrove, Pb, Cd, Heavy Metal

The study was conducted on heavy metals contents of water, fish tissues and sediment from Lagos lagoon complex, Nigeria. The aim was to assess the current environmental health/pollution status of the lagoon from three sample stations: Ologe lagoon [1], Badagry creek [2] and Lagos island [3]; each having three (3) hotspots. In all, twelve (11) heavy metals were determined between June and November, 2018. Heavy metals: Zn, Fe, Pb, Cu, Na, Potassium, Ca, Mn, Cd, Hg and Nickel were determined using Atomic absorption spectrophotometer (AAS). Results of mean Heavy metals in fish tissues were: Zn (0.741±0.38), Fe (5.59±8.32), Pb (0.12±0.17mg/l), Cu (0.16±0.25), Na (9.38±0.25), Ca (116.68±41.53), Mn (0.76±0.96), Pb (0.01±0.0), Cd (0.02±0.0), Potassium (12.09±2.34), Ni (0.02±0.02) and Hg (0.01±0.0). Statistical analysis showed variations in the distribution of Heavy metals which are mostly within recommended limits of WHO, FME, & LASEPA. Except for iron (Fe), which was found in excess in fish tissues, and other metals (lead), found in higher conc. in sediments than in water and fish tissues combined. This is indicative of heavy metals bio-accumulation in the study area.
