Probabilistic risk assessment for linear alkylbenzene sulfonate (LAS) in sewage sludge used on agricultural soil.
Deterministic and probabilistic risk assessments were developed for commercial LAS in agricultural soil amended with sewage sludge. The procedure done according to ILSI Europe's Conceptual Framework [Schowanek, D., Carr, R., David, H., Douben, P., Hall, J., Kirchmann, H., Patria, L., Sequi, P., Smith, S., Webb, S.F., 2004. A risk-based methodology for deriving quality standards for organic cont...
متن کاملBiodegradation of Linear Alkyl Benzene Sulfonate by Sequencing Batch Reactor in Sanitary Wastewater
Introduction: Detergents lead to many environmental problems. The main aim of this study was to evaluate sequencing batch reactor (SBR) efficiency on Linear alkyl benzene sulfonate (LAS) removal. Materials and Methods: In this experimental study, to investigate the removal efficiency of LAS, a SBR reactor was used. A roughly 12-hour operating cycle was chosen which included the discharge time ...
متن کاملUncertainty Techniques in Environmental Risk Assessment
How much does a chemical present a real risk to human and environment? The goal of risk assessment is to estimate the likelihood and the extent of adverse effects occurring to man, animals or ecological systems due to possible exposure(s) to substances. The assessment of whether a substance presents a risk to organisms in the environment is based on the comparison of a predicted environmental c...

متن کاملUncertainty and precaution in European environmental risk assessment of chemicals.
It is recognised that there is a need for a proper treatment and transparency of uncertainty in risk assessment and management, especially in view of the upcoming proposed new chemical policy REACH, which delegates the responsibility for conducting risk assessments to industry. The current EU risk assessment for new and existing substances is largely deterministic and prudential measures are im...
