SEWAGE SLUDGE BIOCHARS MANAGEMENT – ECOTOXICITY, MOBILITY OF HEAVY METALS AND SOIL MICROBIAL BIOMASS

Abstract

Production of biochar from sewage sludge may be a promising solution for sewage sludge management and improvement of soil properties, including carbon dioxide sequestration. The aim of the study was to compare the effects of biochars derived from different sewage sludges on soil physicochemical and biological properties, ecotoxicity and plant yield. 188 more words

CHROMIUM HAZARD AND RISK ASSESSMENT: NEW INSIGHTS FROM A DETAILED SPECIATION STUDY IN A STANDARD TEST MEDIUM

Abstract

Despite the consensus about the importance of chemical speciation in controlling the bioavailability and ecotoxicity of trace elements, detailed speciation studies during laboratory ecotoxicity testing remain scarce, contributing to uncertainty when extrapolating laboratory findings to real field situations in risk assessment. 211 more words

WHICH COMMONLY MONITORED CHEMICAL CONTAMINANT IN THE BOHAI REGION, YANGTZE AND PEARL RIVERS OF CHINA POSES THE GREATEST THREAT TO AQUATIC WILDLIFE ?

Abstract

This study assessed the relative risk of 29 chemical contaminants to aquatic wildlife in the Bohai Region, Yangtze and Pearl Rivers of China. River monitoring data from 2010–2015 for metals, pesticides, plasticisers, surfactants, poly-aromatic hydrocarbons, flame retardants and ammonia were collected. 171 more words
