Determination of Level of Lead (Pb) and Cadmium (Cd) Migration on Bowl and Clear Plastic Cup Using Atomic Absorption Spectrophotometer

Tilapia fish waste and livestock manure are an environmental problem, besides being smelly pollution will also cause disease disorders for humans. The purpose of this study was to determine the levels of micronutrients of iron (Fe) and copper (Cu) on pellets from the fermentation of waste tilapia (oreochromis mossambicus) using adhesive goat manure. Fish waste was fermented for 15 days and mixed with adhesive goat manure and then was processed in a pellet making machine. The Fe and Cu levels were determined using Atomic Absorption Spectrophotometer (AAS). The results of the determination of levels Fe was 137 ppm and for Cu was 4.1 ppm.

The maximum level of mercury permitted in fish by BPOM RI is 0.5 mg/kg. This study was conducted to determine the level of mercury in fish often consumed in Medan Indonesia. Fish samples were collected from 7 traditional fish market outlets and 1 supermarket in Medan in December 2019. Fish samples were dried using an oven at 1030C untill a constant dry weight was attained. Then, the digestionprocess was carried out using concentrated nitric acid and perchloric acid. Determination of mercury level was carried out using CV-AAS method with 900 H Perkin Elmer atomic absorption spectrophotometer equipped with MHS-15 (Mercury Hidride System). The results showed that the level of mercury in pelagic fish was found significantly in yellowfin tuna (Thunnusalbacares) of 27.3865 ± 0.3326 µg/kg; mackerel tuna (Euthynnusaffinis) of 17.8570 ± 0.0121 µg/kg; skipjack tuna(Katsuwonuspelamis) of 17.4507 ± 1.5893 µg/kg; spanish mackerel (Scomberomoruscommersonii) of 10.5767 ± 0.1862 µg/kg; grouper (Epinepheusfuscoguttatus) of 9.9736 ± 0.9115 µg/kg; mackerel (Rastreligerkanagurta) of 6.5364 ± 0.1935 µg/kg and dumersal fish were found significantly in red snapper (Lutjanuscampechanus) of 14.0966 ± 0.8555 µg/kg; stingray(Dasyatissp) of 61.3146 ± 0.8149 µg/kg; ariid catfish (Arius thalassinus) of 13.2533 ± 0.7586 µg/kg; black pomfret(Parastromateusniger) of 10.7755 ± 0.4605 µg/kg; sardine(Sardinellasp) of 6.5464 ± 0.1036. The results showed that the larger fish has the higher mercury level. The level of mercury in these analyzed fish samples was below maximum level permitted by BPOM RI.

The research about validation of the method of Hg determination on the sample from wastewater treatment plant (WWTP) PT. Badak NGL Bontang, Kalimantan Timur using cold vapour-atomic absorption spectrophotometer (CV-AAS) techniques has been conducted. To obtain a valid measurement result, determinations of the important several parameters that influence the method validation are used. The results of research showed that 20% SnCl2 solution could be used as a reducing agent. The analytic performance of measurement obtain is good, showed with the linearity (r) value ≥ 0.995, LOD was 0.2530 ppb, LOQ was 0.8432 ppb, MDL was 0.6427 ppb and repeatability and reproducibility are shown as % RSD < 2/3 CV Horwitz values. The accuracy of this method is very good with a percentage of recovery value of 114.88%. Based on the results of this research, CV-AAS method can be used in the determination of Hg in WWTP samples with the valid results.

Batang Kuantan River is a river that still has a wild gold mine along the flow. Problems arising from the gold mine is the content of the metal it produces, one of which is mercury. Mercury is used in gold mining This research was conducted to see the mercury contained in the water in the flow of Batang Kuantan river. Geochemical studies have been performed by determining the pH and concentration of metal mercury (Hg) determination in water samples using Atomic Absorption Spectrophotometer (AAS). The results showed that The concentration of Hg on samples A1 and A3 is 0.009 mg / L and 0.0078 mg / L. The A2 and A3 samples found a low reading of the limit of detection. The concentration values of Hg samples A1 and A4 are above the standards specified by PP No.82 tahun 2001 i.e 0.002 mg/L.

Mixed Feeds

Abstract Dibutyltin dilaurate is extracted from finished feed with warm chloroform. The chloroform extract is filtered and a 25 ml aliquot is concentrated in the presence of methanol until all traces of chloroform are removed. The methanol solution is diluted and feed interferences are removed by filtration. The filtered solution is aspirated into an atomic absorption spectrophotometer with a triple-slot burner head, using an air-acetylene flame. The instrument response to tin at 286.3 nm is recorded. Essentially theoretical recovery (100.5— 101.9%) has been obtained for tin in laboratory-mixed feeds.
