Plastic has affect bordering polluted lake (8)
I believe the answer is:
bakelite
'plastic' is the definition.
(Bakelite is an example)
'affect bordering polluted lake' is the wordplay.
'affect' becomes 'bite' (I can't justify this - if you can you should believe this answer much more).
'bordering' indicates putting letters inside.
'polluted' indicates an anagram.
'lake' is an anagram of 'akel'.
'bite' placed around 'akel' is 'BAKELITE'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for bakelite that I've seen before include "'Type of hard plastic, used in old telephones (8)'" , "Type of hard plastic, in old telephones say" , "Early form of plastic used for tableware, telephones etc" .)
