| [preliminary study on the biological control of dengue vectors by fish in liouchyou prefecture, pingtung county, taiwan]. | an investigation made in may 1989 with questionnaires to 2,480 families in liouchyou prefecture, pingtung county, showed that there were about 6,533 water containers in the whole village, of which 49.83% were used to store water for drinking, and the remaining 50.17% were used for washing clothes and watering plants. 32.42% of the residents volunteered to rear fish in the family water containers to control the mosquito population. during the period from april to october 1989, there was a total a ... | 1990 | 2402027 |
| acute toxicity and bioaccumulation of arsenic in tilapia (oreochromis mossambicus) from a blackfoot disease area in taiwan. | the general objective of our work was to determine the acute toxicity and bioaccumulation of arsenic (as) in tilapia (oreochromis mossambicus) from the blackfoot disease (bfd) area in taiwan. the average concentration of as in pond water ranged from 17.8 to 49 microg l(-1). acute toxicity tests showed that the as concentration that caused toxicity to tilapia ranged from 69 060 microg as l(-1), in the 24-h toxicity test, to 28 680 microg as l(-1), in the 96-h toxicity test. we measured as concent ... | 2003 | 12900944 |

| spatial analysis of potential carcinogenic risks associated with ingesting arsenic in aquacultural tilapia (oreochromis mossambicus) in blackfoot disease hyperendemic areas. | this work analyzed spatially potential carcinogenic risks associated with ingesting arsenic (as) contents in aquacultural tilapia (oreochromis mossambicus) in coastal regions of southwestern taiwan, where the blackfoot disease prevails. sequential indicator simulation (sis) was used to reproduce as exposure distributions in groundwater based on their three-dimensional variability. a target cancer risk (tr) associated with ingesting as in aquacultural tilapia was calculated to evaluate the potent ... | 2006 | 16568791 |
| a pbtk/td modeling-based approach can assess arsenic bioaccumulation in farmed tilapia (oreochromis mossambicus) and human health risks. | a biologically based risk-assessment model of arsenic (as) exposure evaluated farmed tilapia (orechromis mossambicus) and human health during tilapia consumption in an area of southwestern taiwan where blackfoot disease (bfd) occurs. the risk assessment addressed exposures to city residents who lived in taipei, taichung, and kaohsiung, as well as subsistence fishers living in the bfd area who consumed tilapia. the models implemented included a physiologically based toxicokinetic and toxicodynami ... | 2005 | 16637146 |
| effects of ca2+ or na+ on metallothionein expression in tilapia larvae (oreochromis mossambicus) exposed to cadmium or copper. | the objectives of this study were to try to determine the reasons of the external ca(2+) and na(+) enhancement of cd(2+) and cu(2+) resistance in fish. tilapia larvae at 3 days posthatch were exposed to (a) 0 (control), 40 microg/l cd(2+), 40 microg/l cd(2+) + 2 mm ca(2+) (cd/hyper-ca), and 2 mm ca(2+) or (b) 0 (control), 75 microg/l cu(2+), 75 microg/l cu(2+) + 0.52 mm na(+) (cu/hyper-na), and 0.52 mm na(+). after 48 hours, results indicated that (1) cd/hyper-ca and cu/hyper-na treatments showe ... | 2007 | 17165107 |

| a biotic ligand model-based toxicodynamic approach to predict arsenic toxicity to tilapia gills in cultural ponds. | farming of tilapia oreochromis mossambicus is an important aquacultural activity in taiwan. due to the elevated arsenic (as) concentration in pond water, it is important to assess the bioavailability and toxicity of as to tilapia for protection of aquatic life and human health. in the present study, we developed a biotic ligand model (blm)-based toxicodynamic approach to dynamically predict both acute and chronic effective concentrations of as to tilapia in two tilapia farms located at pudai and ... | 2009 | 19104762 |
| bioavailability links mode of action can improve the long-term field risk assessment for tilapia exposed to arsenic. | the objective of this paper was to develop a mechanistic-based framework to explicitly incorporate the factors controlling the bioavailability, toxicodynamics and mode of action to enhance predictive ability of arsenic (as) toxicity to protect the health of farmed tilapia oreochromis mossambicus. we linked the biotic ligand model and damage assessment model to develop a toxicokinetic model for elucidating the site-specific temporal changes of as bioavailability and to characterize how the fish r ... | 2009 | 19251322 |
| assessing and managing the health risk due to ingestion of inorganic arsenic from fish and shellfish farmed in blackfoot disease areas for general taiwanese. | this paper assesses health risks due to the ingestion of inorganic arsenic from fish and shellfish farmed in blackfoot disease areas by general public in taiwan. the provisional tolerable weekly intake of arsenic set by fao/who and the target cancer risk assessment model proposed by usepa were integrated to evaluate the acceptable consumption rate. five aquacultural species, tilapia (oreochromis mossambicus), milkfish (chanos chanos), mullet (mugil cephalus), clam (meretrix lusoria) and oyster ( ... | 2010 | 21134715 |
| health risks for human intake of aquacultural fish: arsenic bioaccumulation and contamination. | aquacultural tilapia (oreochromis mossambicus l.) and shrimp (penaeus monodon l.) from groundwater-cultured ponds in southwestern taiwan were analyzed to estimate arsenic (as) bioaccumulation and the potential health risk to human intake. most of aquacultural ponds exhibited higher arsenic than maximum allowed concentrations (50 μg l(-1)) in pond water of taiwan. arsenic levels in tilapia in budai, yichu and beimen were 0.92 ± 0.52 μg g(-1), 0.93 ± 0.19 μg g(-1) and 0.76 ± 0.03 μg g(-1), respect ... | 2011 | 21879859 |
