Several researches have been conducted about "Analysis of Heavy Metal Content Mercury (Hg) On Whitening Face Cream Circulating On Percut Sei Tuan Sampali area with Atomic Absorption Spectrophotometer (AAS)". The research study was run at the Health Central Laboratory of North Sumatra. This study aimed to determine the levels of mercury (Hg) in the whitening face creams that ciirculating in the Percut Sei Tuan Sampali district. It also need to determine the levels of mercury (Hg) from Percut Sei Tuan Sampali area that accordance with the Regulation No. HK.03.1.23.07.11.6662 POM. However, this was an experiment study with a random of 5 samples among the whitening face cream at Percut Sei Tuan Sampali area. Thus, this area presented that the heavy metal mercury (Hg) from 5 samples were obtained the results that samples 1A was 1.5429 mg / L, samples 2A is 1.5334 mg / L, samples 3A is 1.4851 mg / L, samples 4A is 1.4916 mg / L, the sample 5A is 1, 5180 mg / L. However, the results showed that the mercury (Hg) value was above the levels was determined by BPOM RI, (the permission terms of heavy metal contamination Mercury (Hg) 1 mg / L No. HK.03.1.23.07.11.6662 in 2011). Thus, it was necessary to supervise the facial whitening cream in the Percut Sei Tuan Sampali society.

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

In the era of industrialization, pollution has totally deteriorated the quality and diversity of life. Heavy metal contaminations are the major causes of environment deteriorations. The basic reasons are natural as well as anthropogenic. Chief sources of heavy metal contamination are air pollution, river sediments, sewage sludge, town waste composts, agricultural chemicals like fertilizers and pesticides, and industrial waste like factories releasing chemicals, anthropogenic activities, etc. Agricultural soils in many parts of the world are generally contaminated by heavy metal toxicity such as Cd, Cu, Zn, Ni, Co, Pb, Hg, As, etc. These are due to the long-term use of phosphate fertilizers, sewage sludge, dust from smelters, industrial waste, etc. Heavy metals in soils are detected with some specific instruments like atomic absorption spectroscopy, inductively coupled plasma, inductively coupled plasma-mass spectroscopy, and X-ray fluorescence and spectroscopy. Among all these instruments, atomic absorption spectroscopy (AAS) is the best because it gives the precise quantitative determination. AAS is a method applied for measuring the quantity of the trace elements present in the soil or any other samples.

The estuary of Donan River is an aquatic area that commonly utilized for some activities such as industrial, fisheries and domestic activities. The effluents of many activities may be cause heavy metal contamination for water enivornemant and organism live in the water. The aim of this research was to analyse heavy metal contain Cu and Cd on the mullet (Chelon subviridis) muscle caught at estuary of Donan River, and to determine the safety limit for community consumption. Sampling had been carried out for 6 months, from August 2015 to January 2016. Heavy metal concentration was measured by AAS (Atomic Absorption Spectrophotometer). Result of the study shows that heavy metal Cu and Cd in the fish muscle were 0.5009-2.6021 mg/kg and 0.0165-0.2307 mg/kg, respectively that were higher than safety limit.  Based on the study, the safety limit for consumption is 151.72 g meat/week (for adult 50 kg body weight) and 45.52<br />g meat/week (for child 15 kg body weight).

Heavy Metal Bioaccumulation

Human activities around the estuary of the Manggar river in Balikpapan produce waste disposal and cause heavy metal contamination such as lead (Pb) and cadmium (Cd) in water bodies. The contaminant can endanger the life of aquatic organisms. It can also occurs heavy metal bioaccumulation in the body of the aquatic organisms. The results show that the heavy metal content of Pb and Cd in water, sediment and water biota indicated that the estuary of the Manggar River was contaminated by heavy metals. The content of Pb and Cd in water is 0.276 mg/l and 0.020 mg/l, in sediments is 24.7 mg/kg and 4.52 mg/kg, and in the biota is 4.20 mg/kg and 0.80 mg/kg. This means that fish and shells taken from the waters around the estuary of the Manggar River are not safe for consumption because they can interfere the human health.

The potentially important mechanism of biological mobilization of lead from lake sediments was investigated. Lead concentrations of the crustacean Mysis relicta from Kootenay Lake, determined using atomic absorption spectrophotometry, were compared to published lead sediment concentrations from the same sites. There is a strong correlation between sediment-lead concentration and Mysis-lead concentration. This correlation may indicate that Mysis can accumulate lead from the sediment and return it to the open water.Key words: Mysis relicta, lead, heavy metal contamination, contaminated sediments.

The study was aimed at assessing the levels of some toxic metals of lead and cadmium in selected lipstick products sold in Padang city. Four brands of lipsticks were taken which were BL, NK, PS and WD. The lipsticks were grinded and analyzed for heavy metals (lead and cadmium) using atomic absorption spectrophotometry. Each sample was destructed by nitric acid and perchloric acid (3:1). Destructed samples were added with sodium hydroxide to liberate ammonia and filtered into a 25 mL volumetric flask. The concentrations of heavy metal were measured by using atomic absorption spectrophotometry. The results showed that lead heavy metal contamination was not detected. Whereas, the heavy metal contamination of cadmium in lipstick brands BL, NK, PS and WD were 0.2287, 0.2000, 0.1796 and 0.1220 mg/kg, respectively. The study results showed that all metal contaminations of lead and cadmium were not over the limit which were regulated by National Agency of Drug and Food Control of the Republic of Indonesia.
