The examination of lead metal contamination levels in tomato plants (Solanum lycopersicum L.) planted on the road side in the district Aur Birugo Tigo Baleh Bukittinggi West Sumatra has been carried out. The samples have taken at four yards randomly with a distance of 3,5 m, 20 m and 500 m from the side of the highway. The fruits and leaves of tomato and soils were destructed by using nitric acid, hydrogen peroxide and perchlorate acid and was measured using Atomic Absorption Spectrophotometric (AAS) at the wavelength of 283,3 nm. The results of analysis showed that the rate of Pb pollutants of the tomato fruit were A1 = 1,0725 mg/Kg (planted with a distance of 3,5 m from the road side); A2 = 0,9977 mg/Kg (planted with a distance of 20 m from the road side); A3 = 0,5848 mg/Kg (planted with a distance of 500 m from the road side). The concentration of Pb pollutants of the tomato leaves were B1 = 0,1983 mg/Kg (planted with a distance of 3,5 m from the road side); B2 = 0,1361 mg/Kg (planted with a distance of 20 m from the road side); B3 = 0,1370 mg/Kg (planted with a distance of 500 m from the road side); and the concentration of Pb pollutants of the soils were C1 = 2,6719 mg/Kg (with a distance of 3,5 m from the road side); C2 = 3,1039 mg/Kg (with a distance of 20 m from the road side); C3 = 2,1904 mg/Kg (with a distance of 500 m from the road side). Refferring to the Director General of Drug and Food Control (BPOM) No. 03725/B/SK/VII/89, the maximum contamination levels of metal in Food. for tomato is 1,0 mg/Kg. The maximum contamination levels of metal on the leave : 0,5 mg/Kg, refferring to the Indonesian National Standard (SNI) 7387 – 2009, the maximum contamination levels of metal on the soil is 10 mg/Kg.

Increasing activities of illegal gold mining caused environmental damage of the river. Heavy metal pollution of Hg, Pb, Cd and CN‾ were derived from mining waste dumped into the river. This research was analysed of the metal content of Hg, Pb, Cd and CN‾. Samples were taken at 4 sampling points, for Hg, Pb and Cd were analyzed by Atomic Absorption Spectrophotometry method and CN‾ were analyzed by Uv-Vis Spectrophotometry. The results show that the concentration of Hg was in between 1.30 – 3.35 ppb, Cd 0.1002 – 0.1684 ppm, Pb not detection – 0.988 and CN¯ not detection – 0.72 ppm. All of the metal concentration have passed a specified threshold limit of PP No. 82 Tahun 2001, except for Pb on the ST2 and Cyanide ion on the ST4, that are still below the limit.

ne"> The utilization of animal bones as adsorbent has been widely studied. From several studies showed that animal bones has good potential as an adsorbent of heavy metals. However, the composition of the mineral constituent in bone of animals is different, and manufacturing process also affect the potential of bone as an adsorbent. In this study, the potential of goat bone activated charcoal as an adsorbent for Cu2+, Pb2+, NO3- and CNions have been studied. Activated charcoal of goat bones was made with the carbonization of goat bone at 700°C for 20 minutes, then crushed and sieved to obtain charcoal powder with a size of 100 – 120 mesh. The activation process performed using Na2CO3 activator with various concentration of 2.5%; 5% and 7.5% that contacted for 24 hours. The resulting of charcoal residue was dried and heated in a furnace at 800°C for 15 minutes, washed with distilled water and then dried. Activated charcoal that generated was characterized, and the best of activated charcoal according to the results of the characterization was used for adsorption of Cu2+, Pb2+, NO3- and CN- ions. From the results of characterization showed the goat bone activated charcoal which activated by Na2CO3 5% has the best result. The result of adsorption of Cu2+, Pb2+, NO3- and CN- ions showed that percentage of adsorption are 99,75%; 99,95%; 94,91% and 74,17% respectively. The highest of adsorption percentage of activated charcoal is Pb2+ ion and the lowest is CN- ion.

Tuna fish bone waste has not been used optimally yet. The tuna bone contains phosphate calcium and carbonate calcium so that oxide calcium can be formed when they are calcinated. Oxide calcium pattern which is relatively opened is hexagonal in shape, inside the shape H+ and other ions are trapped hence it is potential to be an adsorbent. This study was conducted to determine the absorption ability of oxide calcium based on various concentrations and contact times. Manganese analysis was performed using Atomic Absorption Spectroscopy (AAS). The highest absorption ability of oxide calcium to manganese based on variation of concentrations (10 mg/L, 30 mg/L dan 50 mg/L) was 60.334% for 50 mg/L of manganese concentration and immerse time of 20 hours with 5, 10, 15, 20, and 24 hours contact time. Optimum asorption was found at 20 hours of immerse time and 50 mg/L of manganese concentration analyzed with a value of 98.19%. Level of calcium and oxide calcium in ash of tuna bones analyzed by complexometry were 22.44% and 31.36%, respectively.

Whitening cream is a mixture of chemicals or other materials which is able to whiten the skin. The presence of heavy metals such as Pb, Cd and Hg in the whitening cream products are very dangerous, because if the heavy metal ions adsorbed into organs, it will cause health problems. This study aims to determine the metal content of lead, cadmium and mercury in the whitening cream products. The sample of whitening cream which is used in this study consists of day cream and night cream. 6 samples ( 3 of daycream and 3 of night cream) were purchased randomly in Pekanbaru market to be analyzed by using atomic absorption spectrophotometer. The result of the study showed the highest contentof Pb was seen in the sample of day whitening cream with values of C134,91 μg/g and the highest content of Cd was seen in the sample of night whitening cream with values of C21,55 μg/g while the highest content of Hg was shown by the sample of night whitening cream with values of B24,18 μg/g. All the results are above the safe limit determined by the National Agency of Drug and Food Control of the Republic of Indonesia BPOM RI No. HK 03.1.23.08.11.07331 tahun 2011.

Cow bone can be used as raw material of craft. Based on the development of science and technology cow bone can be utilized for many purposes, for example, it could be as an adsorbent. Cow bone can also be used as an activated charcoal, because bone contains about 35% of organic compounds. Activated charcoal was made of cow bone through carbonization and activation processes. The activation process used Na 2 CO 3 as an activator which the concentration is 2,5%, 5% and 7,5%. In this experiment, activated carbon of cow bone was used to adsorbed is cadmium, lead, nitrate and chloride ions in solution. Cadmium and lead were analyzed using atomic absorption spectrophotometer (AAS), while chloride was analyzed using Argentometry Mohr method and nitrate was analyzed using Brusin Sulfate method. The adsorption capacity of the activated charcoal cow bones to cadmium, lead, nitrate and chloride ions are 99.9643%, 99.9481%, 90.5885% and 10.145% respectively.

Jamu is one of traditional medicine that is still consumed today. The content of heavy metals (Pb, Cd and Hg) in jamu product is very dangerous to humans, because it can cause health problems such as liver and kidney excreation. The aim of this research was to analyzed the content of lead, cadmium and mercury in the jamu pegal linu product. Six sample products of jamu pegal linu were purchased randomly in traditional Pekanbaru markets to be analyzed by atomic absorption spectrophotometer and cold-vapor atomic absorption spectrophotometer with wet digestion process. The result showed that the content of Pb and Hg in the samples were exceeded the limit of BPOM RI, whereas Cd metal was found below the limit that allowed by BPOM RI.

Vegetable has a lot of vitamins and minerals that useful for people. Therefore, hygiene and safety of vegetables consumed are important for healthiness. Many types of vegetables that circulated in the community were unsafe because allegedly contaminated with heavy metals such as lead, especially the vegetables planted in the roadside. The aims of this study is to determine the metal content of Pb in vegetable water spinach, spinach and soil sample which planted in Kartama street Pekanbaru. Lead content was determined using an atomic absorption spectrophotometer at the wavelength of 283.3 nm. The results showed that the highest of Pb was found in spinach (0.4234 mg/Kg) and soil sample that the spinach planted (1.6418 mg/Kg) was taken from ST1. The result of this study indicates that the sample spinach contains Pb that did not exceed the maximum limit of standar nasional (SNI 01-7387-2009) that is 5 mg/Kg and soil sample is 10 mg/Kg.
