Abstract Purpose The Limoncocha lagoon, inside a Ramsar site in the Ecuadorian Amazon, increasingly hosts ecotourism and energy development activities. This work estimates local sediments’ baseline of As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Pb, V Zn using four methods. makes it possible to apply single integrated pollution indices estimate contamination level ecological risk sediments. Methods Seven si...

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants in sediments and pose a serious risk for freshwater ecosystems. In this study, sediment samples from 24 sites were collected the cyanobacterial bloom-occurring, macrophyte-growing lake bay adjoining river of Taihu Lake. Here, concentration levels, sources, assessment 16 priority PAHs surface typical algae, macrophyt...

A comprehensive evaluation of the residual levels of Organochlorine insecticides (OCIs) in the sediment cores of Cochin Estuarine System (CES) is highlighted in this research article. It assessed the distribution pattern and impact of these xenobiotics in this environmental niche. Fifteen persistent organochlorine compounds (OCs) were quantitatively analysed in the six sediment core samples col...

Studying and understanding the complexity interactions of different factors influencing stream sediment quality is necessary for development successful water management strategies. This study aims to evaluate level contamination by potentially toxic elements (PTEs) (As, Co, Cr, Cu, Mn, Ni, Pb, V, Zn) sediments Nile River. During spring 2019, river were sampled at 23 sites along For each sample,...

Background: Sediments in the aquatic ecosystems can be used as suitable indicators for monitoring contaminants. Then, objectives of this study were to evaluate concentration heavy metals surface sediments Mohammad Abad River, determine degree pollution using some major contamination indices; identify sources (anthropogenic or natural sources) studied metals; and “reference river” river under ec...
