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...

To address the limitations associated with disposal management and treatment process of POME, an alternative that consists eliminating cooling ponds integrating a pretreatment technology combined dewatering device was proposed. Since proposed has not been tested previously, objective this study is to investigate effect thermal solid loading alteration via on thermophilic continuous set up consi...

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...

The tannery industry is characterized by the consumption of a large quantity water, around 30–40 m3 for processing 1000 kg hide or skin. This amount becomes wastewater, containing about 300 different chemicals, mainly refractory organic compounds, with high chemical oxygen demand (COD), total dissolved salts (TDS), chromium, and evolution toxic gases, such as ammonia sulfides, etc. remaining ta...

Wastewater from seven dye and dye intermediate producing industries and a common effluent treatment plant was assessed to characterize the acute toxicity using Daphnia bioassay. The 24 and 48 h EC50 values and its confidence limits were estimated applying the probit analysis method. The 24 h EC50 values for different dye effluent samples A, B, C, D, E and F were 1.35, 17.32, 17.67, 29.18, 46.49...
