Environmental and health impacts of industrial wastewater effluents in Pakistan: a review

Abstract

<jats:title>Abstract</jats:title> <jats:p>In developing countries, one of the most severe modern-day dilemmas is the management of industrial wastewater. In these countries, industrial wastewater effluents are directly discharged into the natural drain, a sewer system, an internal septic tank or a nearby field. Some of these industrial wastewater effluents are inadequately treated or untreated before being discharged. In recent years, in developing countries, urbanization and industrial activities have led to environmental deterioration. This paper was designed to review the health and environmental impacts of inadequately treated or untreated industrial wastewater effluents in Pakistan. The quality of industrial wastewater effluents is responsible for the degradation of the receiving water bodies. This is due to the reason that inadequately treated or untreated industrial wastewater effluents may cause eutrophication in the receiving water bodies and also form a favorable condition for toxin-producing waterborne pathogens. In order to comply with the wastewater guidelines and legislations, there is a need for proper treatment before discharge. In order to minimize the risk to the environment and public health, there is a need for proper treatment processes for industrial wastewater effluents. To achieve unpolluted discharge of industrial wastewater into the receiving water bodies, regular monitoring, proper and suitable treatment, careful planning and appropriate legislation are recommended.</jats:p>

An evaluation of the marine environmental resilience to the north of Qeshm Island

“…The economic approaches have a direct and significant impact on the four measurements of the marine environment which are of confidence of 95% showing the model is well-fit, which is uniform with the studies conducted by Lee et al (2018), Ilyas et al (2019), andWilk et al(2019).…”

One Health Paradigm to Confront Zoonotic Health Threats: A Pakistan Prospective

“…In terms of potable water quality, Pakistan has been ranked 80th out of 122 countries. If water quality issues are not addressed, then a 60% potable water shortage may soon be confronted due to the mixing of community, sewerage, and industrial waste without treatment ( Aziz, 2005 ; Azizullah et al, 2011 ; Bhowmik et al, 2015 ; Khalid et al, 2018 ; Ilyas et al, 2019 ). In 2020, 400+ schools were randomly tested in Pakistan to examine the quality of the water and >50% of the samples were contaminated with highly pathogenic microorganisms ( Ahmed et al, 2020a ).…”

Using fermentation waste of ethanol-producing yeast for bacterial riboflavin production and recycling of spent bacterial mass for enhancing the growth of oily plants

“…This waste affects directly human and animal health and all the environmental life forms. As a result, there is an urgent need to minimize the risk of biological waste through developing efficient waste disposal treatments and strategies (Ilyas et al, 2019).…”
