*Thesis Abstract:*

*The occurrence and biodegradation of selected pollutants in lakes
Palakpakin, Sampaloc, and Pandin in San Pablo City, Laguna, were studied.
Lake water samples were collected during rainy season (August and September
2015) and dry season (February and May 2016) at varying depths. The
selected pollutants were extracted and concentrated using solid phase
extraction (SPE) and analyzed using gas chromatography/mass spectrometry
(GCMS). Tris (2-butoxyethyl) phosphate (TBEP) was the pollutant with the
highest concentration during both the rainy season (104±0.5 ng/L, measured
at the outlet of Lake Palakpakin) and during dry season (932±86 ng/L,
measured in the middle of Lake Sampaloc). Chlorpyriphos and cypermethrin
were also found in all three lakes. The primary biodegradation of tris
(2-butoxyethyl) phosphate and tris (1, 3-dichloro-2-propyl) phosphate was
studied using fixed bed bioreactor. The half-lives were faster under the
light condition (t1/2= 0.8 and 2 days for TBEP and TDCPP, respectively)
compared with dark condition (t1/2=4.2 and 7 days for TBEP and TDCPP,
respectively).*
