A passage is given below with five blanks labelled (A)-(J). Below the passage, five options are given for each blank. Choose the word that fits each blank most appropriately in the context of the passage, and mark the corresponding answer.
These nanomaterials have___(A)___ properties such as chemical reactivity, electronic___(B)___, and antimicrobial activity. Therefore they hold potential to address issues such as combating Climate Change and___(C)___of pollution. Environment nanotechnology involves the use of nanoscale material for addressing___(D)___concerns such as bioremediation, water purification, product recycling and recovery, solid waste management.
The researchers have developed nanoCO2 harvester which can suck CO2 from the atmosphere and convert it into methanol which can further be used as vehicular fuel. The NanoCO2 Harvester can capture more CO2 than usual and is more efficient fuel___(E)___. The magnetically charged___(F)___ have been proved potent in researchers to have effectively carried on adsorption process to remove heavy metals and dyes from the water bodies and they do not readily degrade. They can also be used to clean the underground water___(G)___ with toxic materials such as arsenic, lead, chromium, and mercury. They can also be used to clean up oil spills by using nanosponges.
The method of converting the organic waste into organic manures and fertilizers can also be quickened through use of Nanoparticles. Thus they can reduce the time___(H)___in solid waste management and increases the production of biogas. According to researchers, Iron oxide particles which are non-toxic can be used for the same.The Nanoparticles being small in size have a___(I)___to clump up which make them inactive with prolonged use. Synthesising useful nanoparticles is also challenging as the production of a consistent size is tough. The viability of Nanoparticles such as nanosponge still remains a laboratory success and hasn’t been tested on large-scale. The usage of Nanoparticles also raises health concerns as due to their small size they can be easily___(J)___inside human as well as animal bodies. Due to their ability of long persistence, they may raise concerns such as bio-magnification as well.
