Abstract
Fosfor i željezo esencijalni su elementi potrebni za različite funkcije za biljke, ali i ljude. Jabuka, Malus x domestica Borkh. Ujedno je od voća koje se ubraja među najčešće konzumirane vrste voća u svijetu pa tako i u Hrvatskoj. Budući da navedeni elementi utječu na rast i razvoj biljke te uz to imaju određene zdravstvene utjecaje na čovjeka, htjela se ispitati kolika je prisutnost tih elemenata u jabukama na tržištu grada Zagreba. Nakon prikupljanja i uzorkovanja jabuka, fosfor je određen spektrofotometrijski, a željezo atomskom apsorpcijskom spektrometrijom. U jabukama iz trgovačkih lanaca utvrđen je statistički najveći prosječni sadržaj fosfora u suhoj tvari (0,14 % P) ST, dok one iz trgovina ekološkim proizvodima u prosjeku sadrže statistički najviše fosfora u svježoj tvari (27,97 mg P/100 g svježe tvari). Što se tiče željeza, i u slučaju suhe i svježe tvari utvrđen je statistički najveći prosječni sadržaj u jabukama iz trgovačkih lanaca (15,59 gm Fe/kg ST i 0,261 mg Fe/100 svježe tvari). Ovakvi rezultati mogli bi biti posljedice konvencionalne poljoprivrede.
Abstract (english)
Phosphorus and iron are essential elements required for various functions for plants, but also for humans. The apple, Malus x domestica Borkh., is one of the most consumed fruits in the world, including in Croatia. Since the mentioned elements influence the growth and development of the plant, and also have certain health effects on humans, the will was to examine the presence of these elements in apples on the Zagreb market. After collecting and sampling the apples, phosphorus was determined by spectrophotometry, and iron by atomic absorption spectrometry. Apples from retail chains statistically have the highest average phosphorus content in dry matter (0.14 %P DW), while apples from organic stores statistically have the highest phosphorus content in fresh weight (27.29 mg P/100 g fresh weight). As far as iron is concerned, the statistically highest average content in both dry matter and fresh matter was found in apples from retail chains (15.99 mg Fe/kg DW and 0.261 mg Fe/100 g fresh weight). These results could be the consequences of conventional agriculture.
