The Karnaphuli River estuary, located in southeast coast of Bangladesh, is largely exposed to heavy metal contamination as it receives a huge amount untreated industrial effluents from the Chottagram City. This study aimed assess concentrations five metals (As, Pb, Cd, Cr and Cu) their bioaccumulation status six commercially important fishes, also evaluate potential human health risk for local consumers. hierarchy measured concentration level (mg/kg) was follows: Pb (13.88) > Cu (12.10) As...
Abstract The Meghna River, the largest and widest river in Bangladesh, is important for navigation, irrigation, fish spawning shelter, industrial usages, drinking water sources millions of people living nearby areas. present study illustrated seasonal variation some physicochemical parameters four heavy metals (Cr, As, Cd, Pb) distribution surface River estuary. It also evaluated human health risk adult children due to directly contact with through ingestion dermal pathways. ranges metal...
Contamination of aquatic ecosystems by various sources has become a major worry all over the world. Pollutants can enter human body through food chain from and soil habitats. These pollutants cause chronic diseases in humans mortality if they collect an extended period. Although phytoremediation technique cannot completely remove harmful materials, it is environmentally benign, cost-effective, natural process that no negative effects on environment. The main types phytoremediation, their...
The study area was selected in the Rupsha river basin and sediment samples were collected to determine trace metal concentrations of As, Pb, Cd, Cr along with biological effects, potential ecological human health hazards for adults children. metals detected from sixty composite using an Atomic Absorption Spectrophotometer (AAS) following some sequential analytical procedures. mean organized descending order chromium (Cr) (43.2 mg/kg) > lead (Pb) (29.21 arsenic (As) (5.18 cadmium (Cd)...
This work aimed to determine the level of some toxic elements (As, Cr, Cd, and Pb) in water Rupsha River, Bangladesh, concerning their potential dangers human exposure. The elemental concentrations (mg/L) were determined using Atomic Absorption Spectrometer found decrease order Cr (0.041) > Pb (0.029) As (0.004) Cd (0.002). this river surpasses various international limits, making it unfit for consumption. Furthermore, metal pollution index contamination indicated that was also unsuitable...
Abstract The Karnaphuli, a major river of Bangladesh, located off the coast Chittagong in Bay Bengal is largely exposed to heavy metal pollutants, which may be toxic humans and aquatic fauna. estuary striking example site where human pressure ecological values collide with each other. In spite being supplier fish food for local community, there has been no study carried out date assess potential health risk due contamination species from this estuary. Therefore, aim present was...
Les fleuves Logone et Chari qui se jettent dans le Lac Tchad, sont exposés à toute forme de pollution. Le but ce travail est d’évaluer la contamination par les métaux lourds des eaux, sédiments poissons du Tchad. Trois espèces poissons: Tilapia nilotica, Lates niloticus Arius latiscutatus ont été obtenues au Tchad transportées sous glace laboratoire. Cd, Pb Cr dosés tête, foie, chair os ces poissons, l’eau spectrophotomètre d’absorption atomique. Cd n’étaient pas détectés eaux sédiments. En...
Immunohistochemical techniques have been used to identify Metallothionein3 (MT3) expression specifically detect MT3 levels in the kidney. The employed are highly sensitive, thus allowing detection of very low amount proteins with use antibodies. present study aimed at identifying expressions and localizations kidney tissue estuarine catfish Arius thalassinus from Kuala Gula using immunohistochemical methods. Primary mouse monoclonal anti-MT3 (1F11), primary antibody (1:2000), secondary...
