The study evaluates heavy metals in soil used for Potato cultivation by Atomic Absorption Spectroscopy in awi Zone, Amhara Region, Ethiopia. In this study, 75 soil samples from three agricultural areas, namely: Guaguasa Shikudad, Fagita Lecoma and Banja districts were collected and analyzed for Lead (Pb), Cadmium (Cd), Nickel (Ni), Copper (Cu) and Zinc (Zn) using Atomic Absorption Spectroscopy. The results obtained revealed that the mean heavy metal concentrations for Pb, Cd, Ni, Cu, and Zn were 75.33–77.00mg/kg, 17.11–18.76mg/kg, 60.26-101.78mg/kg, 125.17-383.39mg/kg and 244.20—287.87mg/kg respectively. In general, the level of metals in soil collected from the sampling sites are found to be decreased in the order of: Cu>Zn>Ni>Pb>Cd. Soil analysis showed that the concentration of Cu, Cd and Ni higher than permissible levels there WHO/FAO thresholds for agricultural soils the soil is polluted by toxic heavy metals (Cu, Cd and Ni). Therefore, the soils studied were harmful for the cultivation of potatoes and other agricultural purposes.

ABSTRAKPenelitian ini bertujuan untuk mengetahui struktur populasi dan kandungan logam berat gastropoda (Telescopium telescopium) di Taman Nasional Rawa Aopa Watumohai. Penelitian ini dilaksanakan pada bulan Januari sampai Maret 2018. Lokasi pengambilan sampel penelitian terletak pada mangrove yang tumbuh di Sungai Lanowulu dan Roraya di TNRAW. Penelitian ini menggunakan metode purposive sampel. Penelitian ini menggunakan plot kuadrat ukuran 1 m2 diletakkan di setiap stasiun. Jumlah individu dari T. telescopium dihitung berat dan panjangnya. Selain itu, kandungan logam berat Timbal (Pb) dan Cadmium (Cd) di dalam daging T. telescopium dihitung menggunakan Atomic Absorption Spectroscopy (AAS) di Laboratorium Fakultas Perikanan dan Ilmu Kelautan Universitas Halu Oleo. Struktur populasi T. telescopium ditentukan dengan analisis histogram, distribusi ukurannya ditentukan dengan analisis koefisien variasi (CV). Hasil penelitian menunjukkan struktur populasi gastropoda membentuk kurva normal dengan ukuran kecil. Kandungan logam Pb dan Cd di dalam sedimen dan air laut dari Sungai Roraya lebih tinggi secara signifikan dibandingkan dengan Sungai Lanowulu, disisi lain, kandungan logam berat Pb dan Cd dalam daging T. telescopium tidak berbeda signifikan. Dengan demikian, kandungan logam berat Pb dan Cd pada air laut, sedimen dan daging T. telescopium di sungai Lanowulu dan sungai Roraya berada di atas baku mutu sesuai dengan Kepmen LH. No. 51. 2004. Kata kunci: Gastropoda, Mangrove, Logam Berat, TNRAW. ABSTRACTThis study aims todetermine the population structure and heavy metals contents of gastropods (Telescopiumtelescopium) living in RawaAopaWatumohai National RAWN Park. This research was conducted from January until March 2018. The sampling location of research was in mangroves grown along the Lanowulu and Roraya rives at RAWN Park. This research uses purposive sampling method.  This study used the plot quadrate of 1 m2 widethat placed in each station. The number of individuals of.T. telecopium was counted, while their fresh weight and length of T.telescopiumwere measured. In addition, the content of heavy metals of Lead (Pb) and Cadmium (Cd) into meat of T. telescopium were measured by using Atomic Absorption spectroscopy (AAS) in Laboratory at Faculty of Fisheries andMarine Science at Halu Oleo University. The population structure of T. telescopium was determined by histrogram analysis, its size distribution was determined by coefficient of variation (CV) analysis. The results showed that population structure of gastropods was normal curve with small ranges of size distribution. The content of Pb and Cd into sediment and sea water of Rorayariver were significantly higher as compared than that in Lanowulu river. On the other hand, the content of heavy metals Pb and Cd into meat of T. telescopium was not significantly different. However, the heavy metals contents of Pb and Cd into sea water, sediment and meat of T. telescopiumboth in Lanowuluand Roraya riverswere above the quality standard according to Ministry of Environment No. 51/LH/2004. Keywords : Gastropods, mangroves, Lanowulu and Roraya rivers, heavy metals, Rawa Aopa Watumohai National Park

The increasing content of heavy metals in soil and atmospheric air can lead to serious consequences in the final link of which a person is. To determine heavy metals in atmospheric deposition, the method of biomonitoring of mosses was used. Joint Institute for Nuclear Research scientists started the implementation of the mosses biomonitoring methodology in Azerbaijan 2015. In total, the concentration was determined for 44 elements. Determinations were performed using instrumental analysis of Epithermal Neutron Activation and Atomic Absorption Spectroscopy in 85 moss samples. The species of moss used in the work was Pleurosium schreberi. Based on the analysis results, the most contaminated areas are identified.

Lead (Pb) behavior was studied in soil treated twice with sewage sludge contaminated with lead at interval of 18 months. Soil samples received five different treatments: three with lead [0 (reference); 2,500; 5,000 mug g-1] and two with a mixture of lead and cadmium (interferer) (2,500 + 2,500 and 5,000 + 5,000 mug g-1, respectively). Vases containing treated soil were cultivated with maize in a greenhouse for 75 days. Pb was extracted using nitric perchloric digestion and analyzed by atomic absorption spectroscopy. The soil, containing sewage sludge contaminated by lead presented a higher concentration of Pb. The metal concentration remained constant in all treatments at 20-60 cm depth. No absorption of Pb by the plants was detected.

Ambroxol hydrochloride (AMB), (1s,4s)-4-((2-amino-3,5-dibromocyclohexyl)methylamino) cyclohexanol hydrochloride, is semi - synthetic derivative of vasicine obtained from Indian shrub Adhatoda vasica. It is a metabolic product of bromhexin and it is used as broncho secretolytic and an expectorant drug. Analysis of Flavamed® tablets, in which ambroxol hydrochloride (AMB) is an active component, was performed. UV/VIS spectrophotometry and atomic absorption spectroscopy (AAS) were used. Direct and indirect UV/VIS spectrophotometric methods were used for quantitative analysis of AMB and the following recovery value results were obtained: 100,16% and 95,23%, successively. Content of heavy metals in Flavamed® tablets was determined by atomic absorption spetroscopy.

More still needs to be learned regards the relative contamination of heavy metals and pesticide residues, particularly those found in widely consumed Nigerian food crops like cereals, vegetables, and tubers. In this current study, the heavy metals and pesticide residues detectable in widely consumed Nigerian food crops were respectively quantified using atomic absorption spectroscopy (AAS) and gas chromatography (GC). Specifically, the widely consumed Nigerian food crops included cereals (rice, millet, and maize), legume (soybean), tubers (yam and cassava), as well as leaf (fluted pumpkin, Amaranthus leaf, waterleaf, and scent leaf) and fruit vegetables (okro, cucumber, carrot, and watermelon). Results showed that the detected heavy metals included arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), iron (Fe), lead (Pb), manganese (Mn), mercury (Hg), and nickel (Ni), whereas the pesticide residues included Aldrin, Carbofuran, g-chlordane, Chlorpyrifos, DichloroBiphenyl, Dichlorodiphenyldichloroethane (DDD), Dichlorodiphenyltrichloroethane (DDT), Dichlorvos, Endosulfan, Heptachlor, Hexachlorobenzene (HCB), Isopropylamine, Lindane, t-nonachlor, and Profenofos. Across the studied food crops, the concentrations of heavy metals and pesticides were varied, with different trends as they largely fell below the established maximum permissible limits, and with some exceptions. Our findings suggest there could be a somewhat gradual decline in the concentration of the heavy metals and pesticide residues of these studied food crops when compared to previously published reports specific to Nigeria. To help substantiate this observation and supplement existing information, further investigations are required into the concentration of these heavy metals and pesticide residues specific to these studied food crops at other parts of the country.

Abstract In several series of 581 samples, Higher Fungi, especially from the Boletales and Gasteromy­cetes, were analyzed by atomic absorption spectroscopy on their content of the trace metal silver. The highest Ag-content was found in the Lycoperdales (max. 50 mg/kg dry matter) and in some species of the genus Boletus (max. 15 mg Ag/kg). The other fungi tested showed a mean silver content of 1 mg/kg or lower. The species with the highest amounts of the trace metal were found to enrich silver 300 fold compared to the substrate.
