 ```Sorry for cross posting but I amdetermined to get to the bottom of my problem! I am attempting to undertake biodegradation capacity calculations. The calculations firstly involve identifying contaminants of concern and then stoichiometrically balancing equations which describe their natural attenuation under aerobic and anerobic conditions for the varying terminal electron acceptors e.g oxygen, nitrate reduction, sulfate reduction, iron reduction and methanogensis. An example for napthalene would be as follows: Oxidation 12O2 + napthalene = 10CO2 + 4H2O Nitrate reduction 9.6nitrate + 9.6protons + napthalene = 10CO2 + 8.8H2O + 4.8N2 Fe reduction 48Fe(OH)3 + 96protons + napthalene = 10CO2 + 48Fe2+ + 124H2O Sulafte reduction 6sulfate + 12protons + napthalen = 10CO2 + 6H2S + 4H2O Methanogenesis 8H2O + napthalene = 4CO2 + 6methane I have attempted to balance the above equations for the following contaminants but have had no luck: butylbenzene undecane tridecane decane tetradecane dodecane hexadecane dimethylnapthalene bis (2 ethylhexyl)phthalate Could someone please help me, or point me in the direction look forward to hearing from you Ben Rees Geochemist SRK Consulting Summit House 9/10 Windsor Place Cardiff CF10 3SR Tel: +44 (0) 2920 235566 Fax: +44 (0) 2920 340524 E-Mail: [log in to unmask] www.srk.co.uk Disclaimer The information contained in this e-mail is intended only for the use of  the person(s) to whom it is addressed and may be confidential or contain legally privileged information.
