This study aimed at assessing the ability of sunflower to remediate zinc (Zn) impacted soils and the partitioning factors of Zn in soil-plants interactions. The research method used ex situ experiments using teddy bear sunflower seeds with 8 different treatments for each. This began with the preparation of the sample soil media on garden soil, and the seeding of sunflower seeds. This research was carried out for six months starting in August - December 2020, with Helianthus annuus plants with variations of the Zn. Various concentrations of Zn were applied, ranging from 50 ppm to 350 ppm. Laboratory analysis of Zn was carried out using the Atomic Absorption Spectrophotometry (AAS) method. The research results have revealed that roots have the ability to translocate more Zn than shoots, which suggests a phytoremediation mechanism. Sunflower plants are able to translocate Zn, which proves it reliable for phytoremediation of Zn-polluted soil.

Abstract An atomic absorption spectrophotometric (AAS) method was collaboratively studied by 8 laboratories from Africa, the United States, Australia, and Europe. The samples were dispersed in deionized water. After centrifuging and filtering, the water-soluble copper in the filtrate was acidified and measured by atomic absorption spectrophotometry, in an airacetylene flame, at 324.7 nm. The results from 7 laboratories were satisfactory and no unfavorable comments were received. Repeatability standard deviations ranged from 0.005 to 0.023, and reproducibility standard deviations ranged from 0.012 to 0.062. When compared with the bathocuproine method, the difference in bias between both methods is not significant. They were both adopted as full CIPAC methods, with the bathocuproine method as the referee method. Both methods have been adopted official first action.

Study from the Environmental Office of Yogyakarta, indicates in Kotagede found the pollution of mercury from the environment because of improper disposal of wastewater. This study aims to assess the levels of mercury, creatinine and urea in the serum and urine of people working in several industries in Kotagede and Banguntapan. Subjects of this study were 52 employees in several industries in Kotagede Yogyakarta with a range of ages between 20 - 71 years and length of work between 3 - 38 years. A total of 42 people with the age range was 21 - 63 years and the length of work between 1 - 20 years were taken from industrial employees in Bantul who have almost the same geographical conditions as Kotagede. Determination of mercury levels using the Atomic Absorption Spectrophotometry (AAS) method while the determination of urea and creatinine levels by a Dyasis kit. In Kotagede, there were 3 people (5.8%) with the average mercury serum of 0.217 ppb and no mercury in the urine was found in all subjects. In Banguntapan, one person (2.4%) had 0.200 ppb mercury serum and 6 people (14.3%) had an average mercury urine level of 0.395 ppb. Urine creatinine and urea levels in subjects from Kotagede were higher than those from Banguntapan (p<0.05), despite being on the normal range. The presence of mercury in several industrial employees in Kotagede and Banguntapan is still on the low range even though it was correlated to creatinine levels.

Oil pollution of extraction areas is an undesirable phenomenon, but very present, es-pecially in old farms. In the context in which the depollution of these areas, in Roma-nia, is carried out from public funds, this fact is more and more difficult to achieve. That is why the effect of pollutants on the environment is being analyzed more and more, it often remains that the depollution is done naturally. This material analyzes the effect of metals present in crude oil (Cu, Pb, Zn, Ag, Ni, Mn, As, Cd, V, Cr, S), on the soil affected by a historical accidental pollution in the Moinesti area, Romania. This article presents the results of analyzes performed by metal detection techniques, namely optical emission spectrophotometry with inductive coupled plasma and atomic absorption spectrophotometry. The metals determined in the polluted soil were statis-tically analyzed regarding the dispersion, standard deviation and coefficient of varia-tion compared to the control sample and compared with the results from two areas in Romania. The risk of exploitation of polluted areas was also analyzed, namely the method of pollution indices and the method of combining the effects of pollutants
