Chinese equivalent of: 'ew'? When disgusted by something people will usually say, 'ew, yuck!' or 'ew, gross.' 

Is there an equivalent of 'ew' in Mandarin?

The only things I was able to find about it (here) - just explain what 'ew' means &amp; when to use it, but I want to know if there is an equivalent.
恶(e3) should be the one. 
When feeling disgusted, in Chinese people would say a long 恶(e3), like eee3...

or 恶心（e3 xin1）as an adjective to mean disgusted, which literally means disgusted heart, or in English to have a disgusted heart (feeling) toward someone or something.
