The Okavango Delta in northern Botswana is a 6,000-15,000 km2 seasonal wetland which is home to hundreds of species of wildlife, including birds, fish, crocodiles, and hippopotami. The delta fluctuates in size based on time of year and rainfall. The many species that inhabit the area rely on its waters to reproduce and feed. The presence of phthalates is an area of emerging concern in this water system because of recent changes in agricultural practices upstream. The presences of 9 monoester phthalates were analyzed using LC/MS/MS on samples taken from the summer of 2016. Initially, levels of monobutyl, monoisobutyl, and monoethyl phthalate were found to be above 100 parts per billion (ppb). A healthy water system may have phthalates at approximately 5-10 ppb. Further analysis will provide information on the source and the effects of these compounds. Preserving the reproductive health of wildlife in the Okavango Delta relies on a natural and clean water system. Quantitative analysis of monoester phthalates is a necessary step in ensuring that the Okavango Delta continues to be a functioning habitat for the wildlife of northern Botswana.
