Similar factors govern the uptake of heavy metals and radionuclides in all vascular plants (Olszewski et al. Accumulation in coffee beans depends on many factors, including species, age, root distribution of the plant, physical and chemical nature of the soil (pH, Eh, organic matter, anions, and cations content), proportions and distributions of elements, the use of fertilizers, and the general climatic conditions (Anderson and Smith 2002). Like all other vascular plants, the coffee plant uptakes mineral elements and micronutrients from the soil. They lead to physical changes in the green beans and the formation of more than 900 volatile compounds, many unknown molecules (melanoidins), and the substances responsible for the coffee beverage’s sensory qualities (Wei and Tanokura 2015).

The coffee drink is slightly acidic (pH around 5) and can stimulate humans due to its caffeine content. Unroasted green coffee is one of the most traded agricultural commodities on the international market. ![]() Coffea trees are cultivated in more than 70 countries, mainly in equatorial Latin America, Southeast Asia, South Asia, and Africa. The annual consumption varies in different countries, from 12 kg per capita in Finland to 9 kg in Iceland, 6.5 kg in Canada, 5.8 kg in Brazil, 4.2 kg in the USA to 4 kg in Japan and England, and 3 kg in Poland (Chudy 2014 Roselli et al. Nowadays, it is one of the most popular and widely consumed beverages globally. Froeher known as Arabica and Robusta coffee (Alharbi and Alamoudi 2017 Pigozzi et al. Still, only two species gained substantial economic significance: Coffea arabica L. More than 100 Coffea genus plants are cultivated in the World. ![]() Coffee is a non-alcoholic beverage produced from seeds and berries of the coffee plant (genus Coffea L.) (Roselli et al. ![]()
