[...]determining the available forms of heavy metals in soils is an important approach to the soil contamination assessment, especially in greenhouse areas which have great impact on environment and human health due to intensive use of fertilizers and pesticides containing heavy metals. [...]up to now, heavy metal concentrations of greenhouse soil in Bosnia and Herzegovina and its pollution problem have been studied very little, especially there is no systematical investigation of the dynamics of heavy metals in the greenhouse soil-plant system in intensive tomato production. Since the heavy metals have a long residence time in soils, it is very important to study the status of heavy metals in soil, and their influence on vegetable safety, and consequently human health. DISCUSSION Contamination of greenhouse soils by heavy metals as a result of long-term use of fertilizers and pesticides in food crops production becomes more and more intense, resulting in harmful effects on human health through consumption of food crops grown on these soils (Liu et al., 2014). [...]it is imperative to reduce heavy metal contamination in greenhouse soils, and in order to achieve this goal, legislation of some developed countries has set tolerance limits on heavy-metal additions (fertilizers and biosolids) to soils. [...]the available forms of these elements in the same soil were very low. [...]the amount of available Cr in examined soil was less than 0.1% of total Cr concentration in soil, and from these results it is evident that the total concentration does not provide reliable information on the mobility, availability and toxicity of the heavy metals, especially Ni and Cr.
