Assessment of Bacterial Load in Polyethylene Terephthalate (PET) Bottled Water Marketed in Kathmandu Valley, Nepal by Bikram Gautam, Gaumani Gyanwali, David Wayne Ussery

“…For this study, bottled water was purchased, and parameters like pH, electrical conductivity (EC), total dissolved solids (TDS), heterotrophic plate count (HPC), total coliform count, and Pseudomonas spp. count were determined as per the American Public Health Association, 2005. The pH value of water samples tested ranged from 5.2 to 6.8. …”

The Effect of Plastic Waste Attachment on Branching Coral to Zooxanthellae Abundance in the Kelapa Dua Island Waters, Seribu Islands by Fadel Muhammad, Neviaty Putri Zamani, Meutia Samira Ismet, Muhammad Irlan Assidiq Kusuma Ramadhan

“…The zooxanthellae abundance was calculated using the APHA (American Public Health Association) formula. The results of zooxanthellae abundance on the closure treatment of branching coral samples with black plastic and control had the lowest and highest values by 4.25 x 105 cells/cm2 and 1.38 x 106 cells/cm2. …”

Determinants of Physicochemical Composition of Palm Oil Mill Effluent - Implications on Environment and Bio-digester Treatment Design by E.B. Tambe, A.U. Okonkwo, I. E. Mbuka-Nwosu, C.O. Cookey, E. Agbe, S.C. Onwusa, I.N. Ekpe, U.F. Evuen, J. Okpoghono

“…From a randomly sampled small-scaled mill in each community, and for the lone medium and large-scaled mills, four homogenous samples of POME were collected from sampled small, medium and large-scaled mills for laboratory analysis of potential of hydrogen (pH), dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total carbon (TC), total solid (TS), total suspended solid (TSS), total organic carbon (TOC), total nitrogen (TN), total kjeldahl nitrogen (TKN), ammonia nitrogen (NH3-N), Manganese (Mn), Nickel (Ni), Iron (Fe), Copper (Cu), Chromium (Cr), Cadmium (Cd), Potassium (K), total phosphorus (TP), Calcium (Ca), and Magnesium (Mg) using standard methods for wastewater analysis as described in American Public Health Association. Data was analysed using multivariate analysis of variance, and showed that the physicochemical composition of POME was significantly different (p<0.01) across milling-scales, types of FFBs and seasons. …”
