Pyrethroid sorption to Sacramento River suspended solids and bed sediments.
Sorption of pyrethroid insecticides to solid materials will typically dominate the fate and transport of these hydrophobic compounds in aquatic environments. Batch reactor isotherm experiments were performed with bifenthrin and λ-cyhalothrin with suspended material and bed sediment collected from the Sacramento River, California, USA. These batch reactor experiments were performed with low spik...
متن کاملDesorption of pyrethroids from suspended solids.
Pyrethroid insecticides have been widely detected in sediments at concentrations that can cause toxicity to aquatic organisms. Desorption rates play an important role in determining the bioavailability of hydrophobic organic compounds, such as pyrethroids, because these compounds are more likely to be sorbed to solids in the environment, and times to reach sorptive equilibrium can be long. In t...
متن کاملRemoval of Coliform, Suspended Solids, UV254 and Colour Using Zeolite and Activated Carbon in Riverbank Filtration System
River bank filtratio filtration (RBF) is one of the novel water abstraction alternatives to tackle poor water quality problem in Malaysia. This study was conducted to investigate the potential use of zeolite and activated carbon as filter media in the laboratory RBF system. Characteristics of the materials were first determined using the surface analyzer and X-ray fluorescence method. Filter co...
متن کاملDetermination of Lead, Arsenic and Nickel concentration in Iranian and Foreign Hair Colors
Background & objectives: The tendency of humans, especially women, to have the beautiful appearance, has increased the use of the chemical hair colors. Heavy metals such as lead, arsenic and nickel are present in these products as a preservative and colorant. The purpose of this study was to determine the level of these elements in Iranian and foreign hair colors brands and compare them. Metho...
متن کاملArsenic and Lead Contaminations in Commercial Fruit Juices of Markets in Mashhad, Iran
Background: Contamination of fruit juices with heavy metals presents a risk for human health. Concentrations of lead, and arsenic in fruit juices of market in Mashhad, Iran, were measured using atomic absorption spectrometry (AAS). Methods: Fifty varieties of commercial fruit juices (grape, apple, orange, pomegranate, and multi-fruit) from 5 popular brands (A, B, C, D and E) were purchased fro...
