Oil Spill Dispersants: Does South Africa Have an Alternative?

Piers Chapman

Abstract: The role of geographic and socioeconomic factors on the effects of oil pollution in South Africa is discussed. The sparse population and natural mechanisms provide little reason for alarm in the case of an oil spill at sea except for certain higher risk areas. Effects of previous spills are outlined, and government policy with regard to dispersant usage is discussed.

Continuous-flow toxicity tests using the oil dispersant Corex~t 9527° were performed on the early life stages of four California marine species. Newly released zoospores of the giant kelp, Macrocystispyrifera, embryos of the red abalone, Haliotis rufescens, 4-d-old juveniles of the mysid, Holmes~mysis costata and 10-d-old larvae of the topsmelt, Athermops affinis, were all used in triplicate 48-and 96-h tests. Quantitative verification of dispersant concentrations using UV spectrophotometry was performed twice daily during testing. Results indicated growth of kelp gametophytes was significantly reduced at <2.4 ppm after a 48-h exposure. Of the three animals tested, developing red abalone were the most sensitive (NOEC = 0.63 to 1.50 ppm; LC50 = 1.60 to 2.20 pprn). Mysid juveniles were intermediate in sensitivity (NOEC = 1.66 to 4.20 ppm; LC50 = 4.26 to 7.26 ppm), whereas topsmelt larvae were the least sensitive (NOEC = 12.27 to 14.18 ppm; LC50 = 25.51 to 40.63 ppm). Reproducibility of test data was very high (coefficient of variation = 15.7 to 27.1%).
