High levels of pharmaceuticals, including fluoroquinolones (FQs), have been detected in the effluent from an Indian waste water treatment plant serving bulk drug production intended for the global market. Responses from short-term effluent exposure were studied in fish and rats through explorative analyses of hepatic mRNA abundance, enzyme activities and blood chemistry parameters. Exposure of ...

Considerable debate exists over the primary cause of increased antibiotic resistance (AR) worldwide. Evidence suggests increasing AR results from overuse of antibiotics in medicine and therapeutic and nontherapeutic applications in agriculture. However, pollution also can influence environmental AR, particularly associated with heavy metal, pharmaceutical, and other waste releases, although the...

Pharmaceutical pollution in surface waters poses risks to human and ecosystem health. Wastewater treatment facilities are primary sources of pharmaceutical pollutants, but little is known about the factors that affect drugs entering the wastewater stream. This paper investigates the effects of student pharmaceutical use and disposal behaviors and an annual demographic shift on pharmaceutical po...

The effects of pharmaceuticals in the environment (PiE) are well evidenced, yet from an environmental perspective, remain weakly regulated internationally. Pharmaceutical pollutants addressed under Strategic Approach to International Chemicals Management (SAICM), a global framework for management chemicals and wastes. We provide overview state knowledge on PiE identify international efforts tar...

Household indoor air pollution from open-fire cookstoves remains a public health and environmental hazard which impacts negatively on people's right to health. Technologically improved cookstoves designed to reduce air pollution have demonstrated their efficacy in laboratory studies. Despite the tremendous need for such stoves, in the field they have often failed to be effective, with low rates...

sludge, which is produced as a by-product of all treatment processes, has considerable potential as a fertilizer and soil conditioner. many authorities now discharge the sludge after treatment directly to agricultural land in liquid form, while some others dewater and dry it first. in either case, with proper marketing, it is generally possible for an authority to earn revenue by this means, al...

Contaminant hydrology is the study of processes that affect both ground and surface water pollution. It draws on the principles of hydrology and chemistry. Contaminant hydrology and water quality research seeks to understand the role of soil properties and hydrologic processes on ground and surface water pollution and develop strategies to mitigate their impacts. Research is done at all scales ...
