Additional information
A study was conducted to evaluate the acute toxicity of the palm kernel olein to Skeletonema costatum under static conditions. The procedures followed ISO 10253 (Water quality - Marine Algal Growth Inhibition Test with Skeletonema costatum and Phaeodactylum tricornutum). Skeletonema costatum were exposed towater accommodated fractions prepared fromthe test material at concentrations ranging from 10 - 1,000 mg/L for 72 h and the range of loading rates within which a 50% reduction in algal growth occurred after 72 h was determined on the basis of both the area under the growth curve (EbL50) and specific growth rate (ErL50). Based on the study conditions, the 72 h EbL50 and ErL50 of the test material were determined to be 10 - 100 and 100 - 1,000 mg/L, respectively (Worden and Sherren, 2004).
A study was conducted in accordance with ISO 10253 (Water quality - Marine Algal Growth Inhibition Test with Skeletonema costatum and Phaeodactylum tricornutum) to evaluate the acute toxicity of the palm kernel stearin to Skeletonema costatum under static conditions. S. costatum were exposed towater accommodated fractions prepared fromthe test material at concentrations ranging from 10 - 1,000 mg/L for 72 h and the range of loading rates within which a 50% reduction in algal growth occurred after 72 h was determined on the basis of both the area under the growth curve (EbL50) and specific growth rate (ErL50). Based on the study conditions, the 72 h EbL50 and ErL50 of the test material were determined to be 100 - 1,000 and greater than 1,000 mg/L, respectively (Worden and Sherren, 2004).
A study was conducted in accordance with ISO 10253 (Water quality - Marine Algal Growth Inhibition Test with Skeletonema costatum and Phaeodactylum tricornutum) to evaluate the acute toxicity of the test material to Skeletonema costatum under static conditions. Skeletonema costatum were exposed towater accommodated fractions prepared fromthe test material at concentrations ranging between 10 - 1,000 mg/L for 72 h and the range of loading rates within which a 50% reduction in algal growth occurred after 72 h was determined on the basis of both the area under the growth curve (EbL50) and specific growth rate (ErL50). Under study conditions, the 72 h EbL50 and ErL50 of the test material were determined to be in the range 10 - 100 and 100 - 1,000 mg/L, respectively (Worden and Sherren, 2004).
A study was conducted to evaluate the toxicity of crude palm oil to Skeletonema costatum according to the guideline ISO 14669, ISO 10253 and GESAMP under static conditions Skeletonema costatum were exposed to crude palm oil at 0 and 1,000 mg/L for 0, 24, 48 and 72 h. Palm oil did not have an significant effect on either average growth rate or chain length of Skeletonema costatum. 3,5 -dichlorophenol was used as a reference. After 72 h conducting the test the average specific growth rate was reduced with 15% which is less than the 20 - 80% recommended in the guidelines. Based on these result, the 72h EC50 of test substance to Skeletonema costatum was considered to be > 1,000 mg/L (Worden and Sherren, 2002).
A study was conducted to evaluate the toxicity of water accommodated fractions (WAF) of crude soybean oil to Skeletonema costatum according to the guidelines ISO 14669, ISO 10253 and GESAMP under static conditions. Skeletonema costatum were exposed to crude soybean oil at 0 and 1,000 mg/L for 0, 24, 48 and 72 h. The result of the test showed that the constituent did not have an significant effect on the chain length of Skeletonema costatum. Based on the study conditions, the nominal 72 h EC0 of the constituent to Skeletonema costatum was estimated to be >1,000 mg/L (Worden and Sherren, 2002).
A study was conducted to evaluate the acute toxicity of the coconut oil to Skeletonema costatum under static conditions. The procedures followed ISO 10253 (Water quality - Marine Algal Growth Inhibition Test with Skeletonema costatum and Phaeodactylum tricornutum). Skeletonema costatum were exposed towater accommodated fractions prepared fromthe test material at concentrations ranging from 10-1,000 mg/L for 72 h and the range of loading rates within which a 50% reduction in algal growth occurred after 72 h was determined on the basis of both the area under the growth curve (EbL50) and specific growth rate (ErL50). Based on the study conditions, the 72 h EbL50 and ErL50 of the test material were determined to be 10 - 100 and 100 - 1,000 mg/L, respectively (Worden and Sherren, 2004).
