A resposta correta é a alternativa d) Apenas I, II e IV estão corretas. I - POPs são substâncias orgânicas sintéticas que persistem no ambiente, são tóxicas, lipofílicas e se acumulam na cadeia alimentar. II - A Convenção de Estocolmo é um tratado global para proteger a saúde humana e o meio ambiente dos POPs, proibindo ou limitando severamente sua produção e uso. IV - O DDT é um POP que ainda é usado em alguns países do terceiro mundo para controlar vetores, principalmente o mosquito que transmite a malária. A alternativa III está incorreta, pois a Convenção de Estocolmo inclui 28 produtos, não apenas 12.
