To assess if they were within the safety limits for human consumption, the Cd, Cu, Pb, and Zn contents of fish muscles, bought from separate stalls of the fish markets of nine cities of NW Mexico, were determined by atomic absorption spectrophotometry. Considering all fish and markets, the mean contents were Zn:23.23±5.83, Cu:1.72±0.63, Cd:0.27±0.07, and Pb:0.09±0.04 µg/g (dry weight). Cu, Zn, and Pb did not reach levels of concern for human consumption, but the high Cd values determined in Mazatlán (Mugil cephalus:0.48±0.15;Diapterusspp.:0.57±0.33;Lutjanusspp.:0.72±0.12; small shark:0.87±0.19 µg/g dry weight) indicate that this was the only metal of concern for human health because the daily individual consumption of fish muscle to reach the PTDI would be within 0.27 and 0.41 kg.

The decomposition of two lanthanoid minerals, viz fluorocarbonate bastnasite and phosphate monazite, is described. Iron present in the solution obtained is removed on anion exchanger. Atomic absorption spectrophotometry was applied to the determination of the minor elements present in the mineral, viz. copper, lead, calcium and magnesium. The measurement conditions for the determination of these elements in microquantities were established by using model solutions, and the accuracy and precision of determination were evaluated.

Abstract The article presents the results of research which describes antagonism between Pb-Zn in selected plant species from the area of Czestochowa – Mirow district (north-western part of the Czestochowa Upland). There were analyzed changes in the ratio of Pb/Zn in different organs of the tested plants as a function of the Zn content changes. The content of metals in the plants and the soil was determined using atomic absorption spectrophotometry AAS. In all organs of the plants there was observed antagonistic decrease of Pb uptake and accumulation, resulting from the increase in the concentration Zn. Antagonism between Zn and Pb in roots of the tested plants occurred at Zn content of 200–600 μg/g. In turn, antagonism in stems and flowers occurred at lower contents of zinc (100–180 μg/g). In leaves, antagonism between Pb and Zn occurred when Zn was present at the level of 300–800 μg/g. Ex definition of the analyses confirm the presence of antagonism of lead with regard to high levels of Zn. The study also confirmed that the degree of antagonism depends on the plant species.

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.

Pewarnaan pada proses produksi kain sasirangan menghasilkan limbah yang mengandung logam berat, diantaranya adalah timbal (Pb2+) dan kadmium (Cd2+). Penelitian ini bertujuan untuk mengetahui pengaruh proses fitoremediasi terhadap konsentrasi logam Pb2+ dan Cd2+ dari limbah cair industri sasirangan di Kalimantan Selatan, serta mengetahui pertambahan berat basah eceng gondok. Eceng gondok yang sudah dibersihkan dan diaklimatisasi ditanam dalam reaktor berisi larutan limbah dengan konsentrasi 3% (v/v); 9% (v/v); dan 15% (v/v). Sampel diambil setiap 2 hari sekali sebanyak 100 ml dan dianalisis menggunakan AAS (Atomic Absorption Spectrophotometry). Hasil penelitian ini menunjukkan bahwa konsentrasi logam Pb2+ dan Cd2+ dalam limbah setelah proses fitoremediasi terjadi penurunan. Kadar Pb2+ pada konsentrasi 3% (v/v) semula 0,197 ppm menjadi 0,062 ppm, pada konsentrasi 9% (v/v) semula 0,200 ppm menjadi 0,077 ppm dan untuk 15% (v/v) adalah 0,225 ppm menjadi 0,093 ppm. Sedangkan untuk Cd2+ konsentrasi 3% (v/v) semula 0,110 ppm menjadi 0,059 ppm, konsentrasi 9% (v/v) adalah 0,127 ppm menjadi 0,045 ppm dan untuk konsentrasi 15% (v/v) semula 0,144 ppm menjadi 0,047 ppm.
