particles smaller than 2.5 micrometers in diameter affect human health more than do larger particles. identify 5 chemicals that you might expect to see in high concentrations in these particles in polluted air. why did u pick these chemicals?
The heavy metal particles like lead, arsenic, zinc, copper and selenium are found in more concentrations in industrial contaminants. The sludge or sewage released from industries is runoff into water bodies or into agricultural lands polluting the water and soil. These particles are even enter the air from soil and water and cause the air polllution too. The industrial gases direlctly release such toxic contaminnat particles into the air. Heavy inducstrialized areas subjected to air pollution analysis found to contain these particles in exceeded limits affecting the human and animal healths when they are inhaled through the air.
Recently, the air pollution caused due to presence of heavy metal toxics is being focussed. These heavy metal elements are commonly found in industrialized areas and by any means like air, soil or water they enter the food chains causing toxic effects to the living beings.
