ABSTRAKLipstik merupakan salah satu kosmetik yang paling banyak dan hampir setiap hari digunakan oleh wanita. Timbal adalah salah satu cemaran logam berat yang terdapat dalam lipstik. Penelitian ini bertujuan untukmengetahui kandungan logam berat timbal dalam lipstik yang teregistrasi dan tidak teregistrasi mengguanakan Spektrofotometer Serapan Atom (SSA). Preparasi sampel menggunakan destruksi basah dengan aqua regia. Sampel lipstik yang digunakan sebanyak 24 sampel lipstik yang diambil di wilayah Kota Surabaya, dimana 12 sampel memiliki nomor registrasi BPOM dan 12 sampel tidak memiliki nomor registrasi BPOM. Hasil penelitian menunjukkan adanya kandungan logam berat yang melebihi persyaratan BPOM pada semua sampel lipstikdengan rata-rata kadar 108.9517 ppm untuk lipstik yang teregistrasi dan 102.7183 ppm untuk lipstik yang tidak teregistrasi. Berdasarkan uji Mann-Whitney U diketahui bahwa tidak ada beda antara kadar Pb pada lipstik yang teregistrasi dengan lipstik yang tidak teregistrasi dengan nilai α= 0,05.Kata kunci: Timbal (Pb), Lipstik, Surabaya, Registrasi, Spektrofotometri Serapan Atom. ABSTRACTLipstick is one of the most widely used cosmetics every day by women. Lead is one of the heavy metal contaminants found in lipstick. This study aims to determine the heavy metal content of lead in registered lipstickand not registered using Atomic Absorption Spectrophotometer (AAS). Sample preparation using wet destruction with aqua regia. Lipstick samples were used as many as 24 lipstick samples taken in the Surabaya area, where 12 samples had BPOM registration numbers and 12 samples did not have BPOM registration numbers. The results showed that there was a heavy metal content that exceeded BPOM requirements for all lipstick samples with an average level of 108.9517 ppm for registered lipstick and 102.7183 ppm for unregistered lipstick. Basedon the Mann-Whitney U test it is known that there is no difference between Pb levels on lipstick registered with lipstick which was not registered with a value of α = 0.05.Keywords: Lead (Pb), Lipstick, Surabaya, Registration, Atomic Absorption Spectrophotometry..

This research is to determine the Pb and Cd heavy metal content in Strombus sp and waters of Bukit Bestari District, Tanjungpinang City, Riau Islands Province. The method of this research is purposive sampling method. The instrument used to determine the Pb and Cd heavy metal content is AAS (Atomic Absorption Spectrophotometry). The results of the study showed that the Pb content in seawater at stations I, II, III was 0.611 mg / L, 0.563 m / L, 0.595 mg / L . The results obtained in sediments at stations I, II, III are 10,488 mg / kg, 8,376 mg / kg, 10,052 mg / kg. The results found on Strombus sp at stations I, II, III were 1,975 mg / kg, 1,275 mg / kg, 1,031 mg / kg. For research results on Cd in Strombus sp at stations I, II, III are 0.036 mg / kg, 0.035 mg / kg, station 0.031 mg / kg. The value obtained is the average results obtained from each sub station.

The content of lead (Pb), copper (Cu), zinc (Zn), cobalt (Co), nickel (Ni), and cadmium (Cd) in some selected fruits and vegetables from the Misurata City Market, Libya, were measured using atomic absorption spectrophotometry. The results of this study showed that the average concentrations detected ranged from 0.02 to 1.824, 0.75 to 6.21, 0.042 to 11.4, 0.141 to 1.168, 0.19 to 5.143, and 0.01 to 0.362 mg/kg for Pb, Cu, Zn, Co, Ni, and Cd, respectively. The highest mean levels of Pb, Cu, Zn, Co, Ni and Cd were detected in mango, melon, spinach, banana, mango, and mango fruits, respectively. The levels of these metals found in our study are compared with those reported for similar fruits and vegetables from some other parts of the world. The daily human intakes of Pb, Cu, Zn, Co, Ni, and Cd ascribed to a diet of fruits and vegetables in this region have also been estimated.

Heavy metal pollution is one of the problems that often occurs in Indonesian coastal waters. Comparative methods of looking at heavy metal content in coastal sediments include a way to show similarities and differences between one or more articles by using certain criteria. Different comparison methods to see the heavy metal content in sediments include the AAS (Atomic Absorption Spectrophotometer) method, AAN (Netron Activation Analysis), Regression, and USEPA methods. Based on the comparison of 2 methods, namely: AAS and AAN methods, the most efficient in analyzing heavy metals in sediments in coastal areas is the Atomic Absorption Spectrophotometry (AAS) method compared to the Neutron Activation Analysis (AAS) method.Keywords:CoastalSedimentHeavy MetalSpectrophotometer

A method is described for determining the metal content of paint and vinyl additives by atomic absorption spectrophotometry. The chief advantage of this technique is the ability to analyze multielement metallo-organic compounds and complex mixtures without prior chemical separation at a considerable savings in time, compared to wet chemical methods. Accuracy of better than 1% relative error, and precision equivalent to wet chemical analysis were obtained.

Lipstick or lip dye is a cosmetic dose that serves to coloring, decorative the lips, as a moisturizing material and protect the lips from exposure the sun to provide optimum results. Lipstick should not contain chemicals such as lead (Pb) because the Pb is a heavy metal that is very dangerous when continuously used on the skin, because it will be absorbed into the blood and attack the body organ causing the onset of disease. According to BPOM that the lead rate on the lipstick does not exceed the permissible limit of 20 mg/kg or 20 ppm.This research aims to know the levels contained in the samples are 4 brands of matte lipstick that are sold in the Aceh market in Banda Aceh City with the method of atomic absorption spectrophotometry (AAS). The results showed that on the 4 brands of lipstick matte contain heavy metal lead (Pb) with a rate still qualified allowed by BPOM  is samples A, B, C, and D, respectively at 0.24 ppm; 0.10 ppm; 2.87 ppm and 1.32 ppm, so that the 4 brands of lipstick matte are still used.
