Mennyi idő alatt bomlik le 1 cigarettacsikk a természetben?

Nem tudományos forrás, de érdekes:

"A cigarette takes 3-10 months to mostly decompose and some say it can take up to as much as twelve years; however, the filter which is made of acetate will NEVER fully break down."

Kb:

"3-10 hónap, mások szerint 12 év, de a filter soha nem fog lebomlani teljesen."

Itt is hasonlót írnak:

"Some studies say that cigarette buts never decompose at all (the filters are made of a type of acetate that never fully breaks down)."
