Nevertheless its water-soluble-fraction (WSF) may contain methanol, which appears by a reversion of the transesterification reaction, when biodiesel contacts water. This paper evaluated the loss of the lysosomal membrane integrity in liver homogenate of juvenils Tilapia exposed to biodiesels-WSF, through the increase of the acid phosphatase activity, as an evidence of citotoxicity. Differences in the enzyme activity levels (3.4, 2.3 and 0.8 mU mg−1 total protein over the control value, which was 1.6 mU mg−1 total protein), found for castor oil, waste cooking-oil and palm oil-biodiesels, respectively, were indicative of their toxicity according to this decreasing trend. WSF-chromatograms suggest the cytotoxicity as related to methanol. |
