Presence of hazardous minerals in three major components (soil, forage and buffalo serum) was evaluated for determining extent of metal contamination in Sargodha, Pakistan. Ten soil and forage samples for each season were taken from ten randomly selected sites. 30 grazing buffaloes of �niliravi� breed (calves, non-lactating and lactating) were also sampled randomly from these sites for collection of serum. Heavy metal quantification via atomic absorption spectrophotometry was carried out for selenium, molybdenum and arsenic. Non-significant but positive correlation was found for selenium (Se) concentrations in soil, forage and serum and molybdenum (Mo) concentrations in soil and serum. Negative correlation (p]0.05) was obtained for Mo level between forage-serum and soil-forage which was indicative of molybdenum deficiency in the soil. The results suggested that the heavy metals remained below maximum permissible levels and were non-toxic for the ruminants of the study area.

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.

Background: The objective of this study was to compare the levels of heavy metals (Pb, Hg, and Cd) and metallothionein (MT) in the gills and stomach of two species of mussels (Crassostrea iredalei and Crassostrea glomerata), and to observe the ability of the mussels to absorb the heavy metals Pb, Hg and Cd present in the water. Methods: The mussels were obtained from Mayangan, Kenjeran and Gresik ports, East Java, Indonesia. MT levels were determined using ELISA. Heavy metal levels of Pb, Hg and Cd were assayed using atomic absorption spectrophotometry. Results: The levels of Pb and Cd in water were below the maximum permissible levels for local water quality standards. By contrast, the level of Hg in the water was above the maximum permissible levels for water quality standards. At Mayangan Port (Station 1), the level of Pb was higher than Hg and Cd. Levels of MT and heavy metals varied greatly among of C. iredalei and C. glomerata individuals, but were always higher in the gills than in the stomach. The highest MT level (160,250 ng/g) was observed at Kenjeran Port (Station 2). MT levels were shown to be significantly associated with heavy metal level (P<0.0001). Conclusions: This result indicates that MT may be responsible for the sequestration of these heavy metals, as has already been observed in terrestrial animals.

In the present work six metals (Cu, Pb, Zn, Cd, Mn and Ni) were analyzed for, using atomic absorption spectrophotometry in three main feed brands commonly used in Sokoto (2 commercial feed and 1 locally compounded chicken feed). Initially, the samples were digested with concentrated nitric acid and perchloric acid at about 3700C to 4500C heat in a digestion block. The concentration in ìg/ml of the six metals analyzed for in the feed samples ranged between 0.04 and 1.21 for Cu, 0.01 and 0.55 for Pb, 1.43 and 11.65 for Zn, 0.10 and 0.12 Cd, 0.94 and 3.12 for Mn and 0.004 and 0.25 for Ni. In most of the analyzed samples, the concentration of Cu, Zn, Mn and Ni was found to be lower than the nutritional requirement of broiler chicken at a level which could be harmful for the poultry. Also the study showed the presence of heavy metals (Pb and Cd) in all the feed samples analyzed, but none exceeded permissible levels as set by European Union and National Research Council.Keywords: Atomic absorption spectrophotometry, Chicken feeds, Contamination, Heavy metals, Sokoto, Toxicity

Various essential and toxic heavy metals (Ca, Mg, Cu, Zn, Fe, Mn, Pb, Cd, Cr, and Ni) contents in various types of dried (infant formulaandpowdered) and fluid (freshandprocessed) cow milk were assessed by atomic absorption spectrophotometry. The milk samples were collected from local markets of different parts of Peshawar city, Pakistan. Heavy metal concentrations varied significantly depending upon the type of milk. The heavy metal concentrations in most of the samples were within normal and permissible ranges. It was observed that the samples contained considerable amounts of calcium, while magnesium levels were well above the required levels. The results also revealed that copper levels were slightly lower than the permissible limits. The concentration of zinc in dried milk samples was greater than the values for the liquid milk types. Infant milk formulae had higher iron levels as compared to other milk samples because of the added constituents. Significant differences were observed in the mean values of manganese and cadmium in different types of milk. The toxic metals were within the acceptable limits and did not show significant levels leading to toxicity.

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.
