'particle-laden' originates from the combination of 'particle' and 'laden', where 'particle' refers to a small portion of matter and 'laden' means heavily loaded or weighed down.

'Particle-laden' combines the word 'particle' from Middle English 'particule' and 'laden' from Old English 'hladen', eventually forming the modern English term 'particle-laden'.

Initially, it meant 'loaded with small portions of matter', and this meaning has largely remained the same in modern usage.
