Türkiye’deki satış noktalarından alınan tıbbi bitkilerin çoğu doğadan toplama yoluyla sağlanmaktadır. Bu nedenle
bitkilerin gelişim ve büyümesi kontrol altına alınamamaktadır. Özellikle çevresel kirliliğin tıbbi bitkilerin ağır metal
içeriği üzerine yapabileceği olası etkiler ile ilgili toplumsal farkındalık her geçen gün artmaktadır. Bu amaçla İzmir’de
nüfusun yoğun olarak bulunduğu ilçelerdeki farklı satış noktalarından tıbbi ve aromatik bitkiler toplanmıştır. Bazı bitki
besin elementi konsantrasyonu (N, P, K, Ca, Mg, Na, Fe, Mn, Cu, Zn, B ve Mo) ile toksik ağır metal (Co, Cd, Cr, Ni, Pb
ve Al) içerikleri ölçülmüştür. Sonuçta tıbbi bitkilerin zengin mineral içeriğine sahip olduğu ancak bazı ağır metallerin
kritik düzeylerin üzerinde bulunduğu saptanmıştır.

Many foods and especially plant products are rich in B and therefore, no limit value could be set for dietary intake of B for the human. World Health Organization (WHO) states that a healthy adult can take 1-13 mg of B in daily diet (Demirtas 2010). The most suitable and healthy daily intake of B is 1.5 mg for children, 2 mg for teenager males, 2 mg for females and 3 mg for females before menopause, 2.5 mg for pregnant women and 5 mg for breastfeeding mothers (Demirtas 2010).
  • Molybdenum concentrations of plants changes by seasons as well as the Mo concentration and pH of the soil. Molybdenum concentrations can be 0.5-100 mg kg -1 in dry matter of plants grown in Mo rich soils. WHO (1993) recommends 0.1-0.3 mg of daily Mo intake for adults.

  • ), Cd of thyme (0.26 mg kg -1 ), Ni of mint (39 mg kg -1 ) and Pb of malva (1.69 mg kg -1 ) are higher than those of the other plants. Daghan et al (2013) stated that the critical Ni concentrations for susceptible plants is >10 mg kg -1 and for slightly tolerant plants is >50 mg kg -1
  • . The Ni findings in the current study are lower than the specified reports of the same author. The concentrations of Pb and Cd reported by WHO (1999) for medicinal and aromatic plants are 10 and 0.3 mg kg -1 , respectively. In our study, Pb and Cd concentrations were found to be much lower than these values (Table 4). Previous studies have established that medicinal and aromatic plants can contain some toxic heavy metals like Cd, As, Pb and Hg (Obiajunwa et al 2002; Olukayode Ajasa et al 2004). Hina et al (2011) analysed heavy metal concentrations of 7 different medicinal plants taken from public markets in Karachi and reported the highest Cd concentration for Onosma bracteatum

In another study carried out by Dwivedi & Dey (2002), Pb and Cd concentrations were determined to change between 2.62-32.76 mg kg -1 and 0.0020.056 mg kg -1 , respectively, in the heavy metal analysis conducted on 28 different commonly used medicinal plants.
  • It is known that Al concentration is higher in plants than in animal feed and the Al content of plants differ due to the soil and atmospheric conditions. In different studies, daily Al intake of humans is predicted to be 1.53-160 mg (Sorensen et al 1974). Chromium concentration of wheat flour was reported to be 5-10 μg kg -1 (Anderson et al 1992) and in some spices like black pepper it could present at higher concentrations than those of the other foods (Akgünlü 2012).

In Turkey, the majority of medicinal plants at the selling points are wildly harvested. Therefore, no control exists during their growth and development. The public awareness on effects of environmental pollution in this regard especially with respect to heavy metals in the herbs is increasing. With this objective, medicinal and aromatic plants were collected from herbalists in different, densely populated districts of Izmir Municipality. The concentrations of some essential plant nutrient elements (N, P, K, Ca, Mg, Na, Fe, Mn, Cu, Zn, B, and Mo) and toxic heavy metals (Co, Cd, Cr, Ni, and Pb) and Al were measured. Results showed that herbs are rich in the investigated mineral elements; however, some of the heavy metals are found to be at concentrations above the reported critical levels.
