This paper investigates the leachability and toxicity of this hazardous waste encapsulated in building blocks as an economic useful alternative to disposal. The building block specimens were prepared with different percentages of petroleum sludge (50, 60, 70, and 80 ), and thermally oxidized waste cooking oil was used as a binder. The blocks were subjected to toxicity characteristics leaching tests and its environmental acceptability was evaluated. The results show that the concentration of the PAHs, COD, and heavy metals are within the acceptable level required by the US Environmental Protection Agency�s (USEPA). © Research India Publications 2015. date: 2015 publisher: Research India Publications official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84955560298&partnerID=40&md5=73fe020ea3a27d9cfb7b6aa733cf2272 full_text_status: none publication: International Journal of Applied Engineering Research volume: 10 number: 24 pagerange: 45479-45481 refereed: TRUE issn: 09734562 citation: Johnson, O.A. and Madzlan, N. and Kamaruddin, I. and Oloruntobi, O.O.
