Aquatic environmental monitoring and removal efficiency of detergents

Abstract

In this study, the detergent's concentrations in aquatic environment principally drinking and surface water along River Nile and near rural village were determined to report the influence of different physicochemical characteristics on the distribution of linear alkylbenzene sulfonate (LAS) that lead to toxicity in human beings. The removal efficiency of LAS using zeolite and granular activated carbon technique was assessed.The results showed wide variations observed between surface (0.07-0.38 mg LAS/l) and bottom water (0.05-0.17 mg LAS/l) due to increase in population density and human activities that recorded highest concentration along rural area (surface: 1.24-2.45 and bottom: 0.93-1.083 mg LAS/l). Low concentration of surfactants was found in drinking water (0.005-0.007 mg LAS/l) compared to the concentration of the corresponding water samples along the River Nile. In conclusion, the study indicated that the treatment processes for drinking water production were insufficient for the complete removal of surfactants and adsorption process by using zeolite as low cost, most beneficial, economically feasible method as well as easy to operate for producing high quality of water.

Physicochemical and Bacteriological Qualities of Otamiri River Water and Sediment in South Eastern Nigeria

“…In addition, anionic LAS have been reported to be preferentially adsorbed to sediments [52]. Similarly, in a study on aquatic environmental monitoring and removal efficiency of detergents, LAS variations between surface and bottom waters were reported [53]. In addition, surfactant concentrations in surface waters as high as 0.416 mg/l has been recorded in the United Kingdom [54].…”

Formulation of a Biodegradable Detergent for Cleaning Oily Residues Generated during Industrial Processes

“…Chelating and sequestrant compounds, such as phosphates, are added to increase the cleaning power. However, these compounds are responsible for serious environmental problems, such as the formation of foam, which impedes the input of oxygen and light (Ashforth and Calvin, 1973; El‐Gawad, 2014; Warwick et al, 2013).…”

Uso de productos de aseo y limpieza en hogares de Santa Marta: realidades y posibilidades para un consumo sostenible

“…En las ciudades la contaminación ambiental generada por los residuos es causada no sólo por las actividades industriales sino también por actividades periódicas, desarrolladas a pequeña escala por cada persona desde su propia cotidianidad;las actividades de limpieza y desinfección de pisos, superficies, maquinaria, ropa, utensilios, entre otras, que al utilizar productos no biodegradables como fragancias, jabones, detergentes, blanqueadores y desinfectantes generan sustancias químicas contaminantes y degenerativas, en grandes cantidades y sin ningún tipo de control (El-Gawad, 2014;Schaider, Ackerman, y Rudel, 2016). Sustancias como desinfectantes, blanqueadores y detergentes (Tabla 1) son de uso diario y se utilizan sin precaución, evidenciándose posteriormente en enfermedades respiratorias (Goodyear, Markkanen, Beato, Mohamed, Gore, Galligan, y Quinn, 2017; Bédard, Varraso, Sanchez, Clavel, Zock, Kauffmann y Le Moual, 2014) y cutáneas (Ezendam, Bokkers, Bil y Delmaar, 2017), especialmente entre niños menores de 12 años, quienes suelen ser más vulnerables a los efectos atribuidos a las sustancias químicas que componen este tipo de productos (Garcia, Von Goetz, Siegrist y Hungerbühler, 2017).…”
