Abstract:

Industrial effluents discharged into aquatic environments pose significant ecological and biological threats, particularly to aquatic species like Clariasgariepinus. This study investigates the chronic toxicity of effluents from a noodles food industry on selected environmental bio-indicator fish, Clariasgariepinus, focusing on the gross anatomical features of growth, survival, and condition factor (CF).The following known aquatic contaminants from food industries were selected as the effluent target chemical (TC) of concern: cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb), nickel (Ni) and

The UK environmental regulator, the Environment Agency, is at present in the process of introducing a revision to the effluent discharge consenting system, based on the assessment of whole effluent toxicity - so called Direct Toxicity Assessment (DTA). The concepts of the most ‘sensitive’ species and of risk assessment based on estimation of Predicted Environmental Concentration (PEC) form the basis of the proposed consenting structure. The objective is to control the toxicity of point source discharges to riverine, estuarine and coastal waters and it raises the need for understanding of the n

Abstract:

The most up-to-date regulatory guidelines for establishing acute and chronic numeric limits for copper in freshwaters are based on a biotic ligand model for various species, but the model for Cu lacks data on dietary uptake.

We investigated the effects of diet and its type in the experimental setup and as an exposure pathway to an established amphipod (crustacean) Hyalella azteca (H. azteca) for Cu toxicity assays.

From 41 to 78 organic chemicals were found in toxic fractions using the EPA Phase II test procedures; these included dyes, dye intermediates, process chemicals such as surfactants and possibly metabolic by-products

Following regulation, Leachate Treatment Facility (LTF) wasbuilt in Piyungan landfill to reduce its negative impact to the environment. The effluent from this LTF is regularly monitored to check its compliancewith government standard. However, the standard does not fully addressthe effect of combined components in a particular wastewater on livingorganism. Hence, it is necessary to conduct toxicity test to fill this gap. This study was aimed to analyze the acute toxicity status of leachate preand post-treatment from leachate treatment facility of Piyungan Landfill. The method used for the test

Abstract:

Palm Oil Mill Effluent (POME) final discharge has a risk to the ecosystem due to various harmful contaminants including organic and inorganic materials. In this study, biological monitoring method was used to evaluate the toxicity effects of POME final discharge using Daphnia magna. The physical and chemical nature of toxicants present in the effluent were characterized through acute Whole Effluent Toxicity (WET), and Toxicity Identification Evaluation (TIE) tests. The Toxicity Unit (TU) and median lethal concentration (LC50) of the POME sample were 11.09 and 9.02% (v/v) respectively. From TIE
