One of the main daily consumer products in Peru is potato, but in recent years, the addition of agrochemicals with possible heavy metal content, such as cadmium (Cd) has decreased the quality of the final product resulting in a negative impact on soils. The objective of this study is to determine the concentration of Cd in cultivation areas and in potato plantations. For this purpose, 6 tuber samples, 6 leaf samples, as well as 6 samples of agricultural soil used for cultivation were taken. Subsequently, the concentrations of Cd were evaluated by atomic absorption spectrophotometry, and the results were subjected to variance analysis and mean comparison test (Tukey p<0.05). Soil analysis for Cd shows that 50% of samples are not suitable for agricultural use, with concentrations reaching 3.99 mg kg−1 Cd; 83% of tuber samples pose a health risk, exceeding the Maximum Allowable Limits (0.1 mg kg−1) set by the Codex Alimentarius; and in the case of the leaves as a whole they have alarming levels of Cd, exceeding 2 mg kg−1.

Quality wines are produced in our country. The main objective of this paper was identification of toxic matter, heavy metals and minerals in wines as final produce, with a view of improving nutritional quality of our wines, produced in 2008-2009.Another important fact for this research was the determination of the presence of remnants from protective solutions containing toxic elements (Cu and Pb)[1].[1] Evgjini Papazisi Tonin Rjolli Dr. Abdul Sinani "Food Technology and Environ-mental Protection (Teknologji ushqimore dhe mbrojtje mjedisi1)".

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.

All living things need water, because water is the most important essential material for life. One of the substances in water is iron (Fe). According to Permenkes RI number 492 / MENKES / PER / VI / 2010 levels of iron (Fe) allowed in drinking water is 0.3 mg/L. This study aimed to determine the amount of Fe metal content in PDAM water in Pidie Jaya Regency (Mon Krueng Meureudu PDAM, Panteraja PDAM, and Ulim PDAM) using the Atomic Absorption Spectrophotometry (SSA) method with wet destruction. The results of the analysis of iron content in PDAM water in Pidie Jaya Regency are PDAM Ulim 0.0628 µg/L, Panteraja PDAM 0.1068 µg/L, and Meureudu PDAM 0.0055 µg/L. In other words, PDAM water in Pidie Jaya Regency is still at the specified level. It is expected that PDAM Pidie Jaya will continue to maintain the quality of iron (Fe) levels so as not to exceed the maximum levels that have been set.

Abstract The atomic absorption method studied last year was re-examined and extended to include calcium and sodium. The procedures were submitted to 16 collaborators for determination of Ca, Cu, Fe, Mg, Mn, Na, and Zn. Results for Ca and Na were discouraging; further study is recommended.

Abstract The official first action AOAC method for the spectrophotometric determination of biuret in urea, 2.072—2.074, was compared with official first action AOAC method 2.C01-2.C03 (atomic absorption spectrophotometry), 2 simplified versions of 2.072-2.074, and modified versions of 2 alternative procedures of the International Organization for Standardization. Three synthetic urea samples (0.3, 1.4, and 3.0% biuret) and 1 commercial urea sample (1.0% biuret) were analyzed. The methods proved to be equivalent and none showed a definite advantage over 2.072-2.074. The purification of biuret and the interference by ammonia are also discussed.
