Arsenic accumulation in a freshwater fish living in a contaminated river of Corsica, France

Advance in research on the occurrence and transformation of arsenic in the freshwater lake ecosystem

“…As 在鱼体组织中的含量与水体环境中 As 的浓度呈显著正相关 [20] 。 鱼鳃、鳃盖及肝脏中含 As 量最高, 而鱼肉中含 As 量较低 [72] ,As 的生物累积优先发生在鱼的代谢器官或组织中 [73] 。 淡水鱼类体内 As 含量及 As 形态在不同地区、不同种类之间差异较大 [8] ,总体上 As 含量水平较低 [74] ,一般在 0. 1-10 mg / kg( 干重,表…”

Short-term exposure of arsenite disrupted thyroid endocrine system and altered gene transcription in the HPT axis in zebrafish

“…Hence, As contamination in aquatic environment is becoming a critical issue in several regions around the globe. For example, C aceres et al (1992) reported high As concentrations up to 21 mg L À1 in Lao River, Chile, Culioli et al (2009) found As concentrations of 18e2330 mg L À1 in Presa River, France, and Wang et al (2010) showed As levels of 147e177 mg L À1 in Yangzonghai Lake, China. The elevated As concentrations in aquatic environment are far above the USEPA provisional guideline value of 150 mg L À1 , potentially adversely impact aquatic environment (USEPA, 1999).…”

Accumulation, biotransformation, and biochemical responses after exposure to arsenite and arsenate in the estuarine polychaete Laeonereis acuta (Nereididae)

“…Natural groundwater can contain high concentrations of inorganic As species, mostly due to geological composition and reduction conditions (Habuda-Stanić et al 2007). On the other hand, it is known that anthropogenic activities can contribute greatly to accumulation of As in the water, sediments, and some aquatic animals (Culioli et al 2009). In Brazil, Mirlean et al (2003) related a high accumulation of arsenic in sediments from Patos Lagoon estuary near the city of Rio Grande, southern Brazil, a result that authors linked to the existence of fertilizer factories in the study area.…”
