ecotoxicity of rhodium (rh) from the model of mining waste water side stream was examinedin this paper. rh was extracted from the model of the mining waste water using an emulsion liquid membrane(elm). the extractions were done at ph of 1.87 and ph 2.92 and 41.6 % and 46.2 % of rh was extractedrespectively. the side streams of ph of 1.87 and ph 2.92 after the extractions were examined for ecoto...

Quantification of risks to the ecosystem is necessary for cost-effective remediation strategies. Contaminant endpoints need to be established that consider the bioavailability of toxicants in soil. The challenge is to develop methods that assign risk to the bioavailable toxic contaminants, thereby protecting ecosystems, while balancing remediation costs. Our objective was to evaluate changes in...

Antihypertensive drugs are among the most prescribed drugs. Olmesartan acid, of sartan class, belongs to a relatively new generation antihypertensive called angiotensin II receptor blockers. There very few studies on presence and fate sartans in environment, despite them being marketed huge quantities, metabolized low percentages, detected wastewater water bodies. This paper presents study less...

Ecotoxicity testing is a crucial component of chemical risk assessment. Still, due to methodological difficulties related to controlling exposure concentrations over time, data on long-term effects of organic chemicals at low concentrations are limited. The aim of the present study was, therefore, to test the applicability of passive dosing to maintain stable concentrations of the organochlorin...

This study gave a review of some of the existing life cycle assessment (LCA) methods focusing on ecotoxicity, and made assessments of the ecotoxic impact of pesticide use in an example Swedish winter wheat field from a 2005 inventory and an example Brazilian soybean production field. Pesticides are used worldwide within agriculture and are under constant development aiming to increase the contr...

BACKGROUND Recent studies have highlighted the possibility of using a mixture of three fungal toxins produced by Ascochyta caulina as a bioherbicide to control noxious weeds. However, to assess the commercial potential of this new bioherbicide, it is necessary to increase knowledge regarding the environmental behaviour of these toxins, and particularly their effects on non-target organisms. A n...

This research aims to analyze the environmental impact of six fibers in textile industry: conventional and organic cotton, silk, jute, flax, polyester. The study used a life cycle assessment (LCA) methodology with cradle-to-gate system boundary analyzed stages agriculture, spinning, weaving, dyeing. In agriculture production, five categories (i.e., fossil resource scarcity, global warming, land...
