According to UNFAO Director Mark Davis, the problem is mainly caused by the circumstances in which chemicals are kept. "This is about very old and toxic materials because they have been kept for a long time and are often held in poor conditions and in outdoor areas," Davis told the daily Utrinski Vesnik. "They may be already exuding and polluting water in rivers and lakes, agricultural lands and air."
Prema riječima ravnatelja UNFAO-a Marka Davisa, problem je u najvećoj mjeri prouzročen okolnostima pod kojima se kemikalije skladište. “Radi se o vrlo starim i otrovnim materijalima koji su držani dugo vremena i često u lošim uvjetima i na otvorenom”, kazao je Davis dnevniku Utrinski vesnik. “Oni možda već luče i zagađuju vodu u rijekama i jezerima, obradiva zemljišta i zrak”.
