Chronic exposure to palm oil mill effluent induces oxidative stress and histopathological changes in zebrafish (Danio rerio).

Several studies have revealed that Palm Oil Mill Effluent (POME) adversely affects fish health systems in various ways. However, further studies on oxidative stress and histopathological changes in fish tissues exposed to POME are essential so that a more comprehensive and detailed understanding of its toxicity is attained. Subsequently, this study investigated oxidative stress indicators, including malondialdehyde (MDA) content and activities of antioxidant enzymes, as well as histological changes in zebrafish (Danio rerio) tissues after chronic exposure to POME.

Dual function of sea grapes (Caulerpa racemosa) as phytoremediator for palm oil mill effluent and as ornamental fish feed formulation.

Phytoremediation is a promising technology for treating Palm Oil Mill Effluent (POME). Moreover, phytoremediators have the potential for various aplication, including as feedstock. Hence, this study aims to elucidate the ability of sea grapes (Caulerpa racemosa) in remediating POME and evaluate their suitability as ornamental fish feed.

Acute toxicity of palm oil mill effluent on zebrafish (Danio rerio Hamilton-Buchanan, 1822): Growth performance, behavioral responses and histopathological lesions.

Evaluating the toxicity of Palm Oil Mill Effluent (POME) is critical as part of the effort to develop waste management regulations for the palm oil industry. In this study, we investigated the acute toxicity of POME on growth performance, behavioral response, and histopathology of gill and liver tissues of zebrafish (Danio rerio). In total, 550 adult male zebrafish were used for the toxicity experiment including range finding test, acute toxicity test, growth performance and behaviour test.
