In 1995, Ksentini became the "United Nations Special Rapporteur" on Toxic Wastes. During the starting of her office, she collected some information on the health effects of throwing out of toxic wastes. After submitting her report in 1997, Ksentini gave negative comments on the "Office of the United Nations High Commissioner for Human Rights". It was for not providing her the necessary funding to carry on the actual finding. After being selected again in 1998, Ksentini developed many proposals on the destroying of toxic waste disposals into developing countries. Her final term as "Special Rapporteur" started in 2001 and ended in 2004.
