Before 2001, the ecological protection area in the Kenting National Park (KTNP), southern Taiwan, was poorly described. In this study, a set of four-year data (2001-2004) of seawater qualities at 19 sampling sites around the Nanwan Bay in the KTNP was used to explore anthropogenic impacts to ecological environment, especially coral reefs. The parameters of water quality were analyzed immediatel...

Stormwater suspended solids typically are quantified using one of two methods: aliquot/subsample analysis (total suspended solids [TSS]) or whole-sample analysis (suspended solids concentration [SSC]). Interproject comparisons are difficult because of inconsistencies in the methods and in their application. To address this concern, the suspended solids content has been measured using both metho...

eight sites were sampled during seven rain events to quantify and identify the sources ofpolycyclic aromatic hydrocarbons in urban runoff in the city of tijuana, mexico. the total σ16 pahsconcentration rangedfrom 1113 to 4866 μg/lin the sampled sites and thetotal suspended solid concentrations ranged from 7725 to 4413 μg/l. the high concentrations of total suspended solids were probably the res...

The distribution and quantitation of enteroviruses among water, suspended solids, and compact sediments in a polluted estuary are described. Samples were collected sequentially from water, suspended solids, fluffy sediments (uppermost layer of bottom sediments), and compact sediment. A total of 103 samples were examined of which 27 (26%) were positive for virus. Polioviruses were recovered most...

To develop urban stormwater management effectively, characterization of urban runoff pollution between dissolved and particulate phases was studied by 12 rainfall events monitored for five typical urban catchments. The average event mean concentration (AEMC) of runoff pollutants in different phases was evaluated. The AEMC values of runoff pollutants in different phases from urban roads were hig...

Rio da Serra watershed presents well preserved fragments of rain forest at the headwaters and small farms at middle and final stretches. These features allowed the study of fluvial hydrochemistry, under quasi pristine conditions. Sampling stations were established in order to represent the basin, and visited during dry, intermediate and wet periods. Obtained results are: temperature (22.1-28.6 ...

Despite suspended solids being an important water-quality parameter in the regulatory process, very little is known about the risks of prolonged exposure to high concentrations of suspended solids in fish, especially marine species. In this study, the green grouper Epinephelus coioides, an important mariculture species with a wide geographic distribution, was exposed to various concentrations (...

unless anaerobic reactor and digesters have been applied worldwide, suitable operation is still challenging. threats of facing with low efficiency operationally, their sensitivity and souring phenomenon are part of typical problems. in this article, the application of electrolysis as an upgrading alternative is investigated for the purpose of controlling its capability on effluent quality promo...

Water samples were collected from Okamini stream and analyzed for some physicochemical parameters. The values showed that electrical conductivity, total dissolved solids, suspended chlorides, sulphates, nitrates phosphates within the range of acceptable domestic water use by WHO. Others such as turbidity, pH salinity not in human consumption. Although, at time evaluation may be an alarming situ...
