Pharmaceutical contamination of shallow groundwater is a substantial concern in effluent-dominated streams, due to high aqueous mobility, designed bioactivity, and effluent-driven hydraulic gradients. In October and December 2012, effluent contributed approximately 99% and 71%, respectively, to downstream flow in Fourmile Creek, Iowa, USA. Strong hydrologic connectivity was observed between sur...

Distilleries produce vast amounts of contaminated effluents which if disposed to the water bodies will pose environmental problems hence need to treat this effluent. A membrane bioreactor with Pseudomonas fluorescens as a decolorizing micro-organism was employed for treatment of distillery effluent over 10 days. The effluent pH changed from being acidic (4.2-5.0) to neutral (7.3-8.0). The efflu...

This study was carried out to investigate the effect of different waters; tap water (control), sewage effluent (100 % & 50 %), sewage effluent with Scenedesmus quadricauda and sewage effluent with Nostoc sp. on plant growth, leaf chlorophyll and Assessment of hygienic (fungi) of wheat and alfalfa plants. The obtained results showed that plant height, herb weight (fresh and dry), total chlorophy...

Septic tank effluent is inherently high in sodium ions relative to divalent cations (high sodium adsorption ratio). The disposal of septic tank effluent to the soil will cause the sodium ions to disperse the clay colloids, resulting in a physical blocking of the soil pores. Hydraulic conductivity will be reduced and the effluent will fail to dissipate into the soil profile. In designing the dis...

The utilization of treated agro-industrial effluents has been recommended as sound option for agriculture irrigations practices and sustainable land management programme. This paper presents the impact of utilizing treated effluent form a distillery industry on physico-chemical properties of soils in an agriculture plot. The effluent was applied in 50 and 100% strength and a control plot receiv...

ANOVA-Analysis of variance; BISBureau of Indian standards; RTRelative toxicity; LAILeaf area index; HIHarvest index This investigation studies the enrichment and translocation of heavy metals in soil and plan of V. faba (Faba bean, var. Pusa Sumit) after fertigation with distillery effluent. A field experiment was conducted in the experimental garden of Gurukula Kangri University, Haridwar, dur...

The androgenic potential of a New Zealand pulp and paper mill effluent was measured by applying a combination of in vitro and in vivo bioassays with mosquitofish (Gambusia affinis) and goldfish (Carassius auratus). The in vivo method assessed the rate of gonopodial development (masculinization) and alterations from normal reproductive behavior in adult female mosquitofish exposed for 21 d to un...

A series of Toxicity Identification Evaluations (TIEs) to identify the cause(s) of observed toxicity to Ceriodaphnia dubia have been conducted on a hard rock mining effluent. Characteristic of hard rock mining discharges, the effluent has elevated (∼3000 mg l(-1)) total dissolved solids (TDS) composed primarily of Ca(2+) and SO(4)(2-). The effluent typically exhibits 6-12 toxic units (TUs) when...

During reperfusion, cardiodepressive factors are released from isolated rat hearts after ischemia. The present study analyzes the mechanisms by which these substances mediate their cardiodepressive effect. After 10 min of global stop-flow ischemia, rat hearts were reperfused and coronary effluent was collected over a period of 30 s. We tested the effect of this postischemic effluent on systolic...
