Abstract
Kontaminanti u hrani su sve tvari koje mogu štetno utjecati na ljudsko zdravlje i na okoliš. S obzirom na prirodu onečišćenja, dijele se na fizikalne, biološke i kemijske. Do zagađenja može doći u svakom dijelu proizvodnje i konzumiranja hrane, od uzgoja stoke ili bilja do pripreme hrane u kuhinji. Najčešći kemijski kontaminanti u hrani su teški metali, skupina elemenata u koju se svrstava olovo, nikal, živa, kadmij, arsen, aluminij i cink. Teško su razgradivi u prirodi i predstavljaju opasnost za ljudsko zdravlje, kao i zdravlje ostalih živih bića u okolišu. Najpouzdanija metoda za određivanje koncentracije teških metala u hrani je spektrometrija masa uz induktivno spregnutu plazmu. Ovom metodom je eksperimentalno određena koncentracija olova, arsena i kadmija u uzorku mrkve. Izmjerena koncentracija arsena u uzorku je manja od 0.01 mg/kg, koncentracija olova iznosi 0.0515 mg/kg, a koncentracija kadmija iznosi 0.0445 mg/kg. Količine navedenih metala u uzorku manje su od najveće dopuštene količine određene zakonom Republike Hrvatske. Konzumiranje mrkve koja je služila kao uzorak je sigurno te ne bi došlo do trovanja teškim metalima.
Abstract (english)
Food contaminants are any substances that can negatively impact human health and the ecosystem. There are three types of contaminants based on the type of pollution – physical, biological and chemical. Contamination may occur in every step of food production or consumption. Most common chemical contaminants are heavy metals. They are a group of elements that consist of lead, nickel, mercury, cadmium, arsenic, aluminum and zinc. Heavy metals are hardly biodegradable and they represent a great danger to human health, as well as health of all other living beings in the environment. The most reliable method for determining an amount of heavy metals present in food is inductively coupled plasma mass spectrometry. Using this method, concentrations of lead, mercury and arsenic were experimentally measured in a carrot sample. Measured concentration of arsenic is less than 0.01 mg/kg, concentration of lead amounted to 0.0515 mg/kg, and concetration of cadmium was 0.0445 mg/kg. Concentration of aforementioned metals is smaller than the highest allowed amount which is regulated by the law of Republic of Croatia. It is safe to consume the carrot which served as a sample and there would be no heavy metal poisoning when eating it.
