Sea traffic emissions accounts for more than half of hazardous nanoparticles in coastal areas
Q. Air along coastal areas is full of hazardous nanoparticles coming from _______ emissions.- Published on 23 Nov 15a. Vehicular emissions
b. Sea traffic emissions
c. Biomass combustion
d. Industrial particles
ANSWER: Sea traffic emissions
Air along the coast is replete with hazardous nanoparticles and close to half of the measured particles are from sea traffic emissions, according to Lund University researchers. The rest of the pollution is from cars and biomass combustion as well as industries and natural particles coming from the sea. This study marks the first time an effort has been made to estimate nanoparticles proportion emanating from sea traffic. Nanoparticles are harmful to health on account of their smaller size which can penetrate deeper into lungs than large particles leading to both cardiovascular and pulmonary diseases. Cubic centimetre contains thousands of nanoparticles. Through comparison of nanoparticle levels, conclusions can be drawn about respective proportions stemming from other sources of emissions.
