Biomonitoring of Engineered Nanoparticles in the Environment

Continuous increase in nanoparticle production raises concerns about their fate in the environment leading to the need of monitoring of their presence, concentration and effects on the living systems. In the studies performed so far, attention was paid mainly to the toxicity/ecotoxicity of the nanomaterials to the range of taxonomic groups – from bacteria to animals and plants – with varying results. Biomonitoring is a technique utilising organisms or their tissues for the assessment of the pollution of the environment and it has been successfully applied to a vast array of pollutants and as such, it is a promising way of monitoring engineered NPs in the environment as well. In this paper, concept of biomonitoring is introduced and general overview of known interactions of NPs and organisms is presented along with the evaluation of possible applications of biomonitoring techniques in the nanoparticle pollution assessment.
