In response to global urbanization and economic development, urban surface water pollution has become a universal challenge and particularly affects densely populated megacities, and Dhaka is no exception. The discharge of 98% of untreated domestic sewage and massive volumes of industrial wastewater from over 7000 industries escalate surface water...

Water quality has recently emerged as one of the utmost severe ecological problems being faced by the developing countries all over the world, and Bangladesh is no exception. Both surface and groundwater sources contain different contaminants, which lead to numerous deaths due to water-borne diseases, particularly among children. This study present...

Coastal wetlands have been enclosed by thousands of kilometers of seawalls in China to obtain extra land for rapid socio-economic development in the coastal region. Although understanding seawall-induced impacts on delta wetlands and their ecosystem can provide valuable decision-making information to support coastal management, quantifying and meas...

Microplastics (MPs) have recently been recognized as potential pollutants and carriers for pathogens in marine, freshwater, and terrestrial environments. They can carry microbial pathogens, hydrophobic organic compounds, persistent organic pollutants, and heavy metals on the surface of these particles leading to unwanted effects on living organisms...

Surface water quality is among the significant challenges in the Sutlej River basin, passing through Pakistan's most densely populated province. Currently, the overall surface water quality is grossly polluted, mainly due to the direct discharge of wastewater from the urban areas to the Sutlej River directly or through stream networks. Escherichia...

Sea level rise (SLR) has a significant impact on the ecosystem services in coastal wetlands. Taking the Liaohe Delta as an example, the SLAMM (Sea Level Rise Affecting Marsh Model) was used to simulate the medium-term (2010–2050) and the long-term (2010–2100) of the spatiotemporal changes of land use in the four scenarios (0.5, 1, 1.5, and 2 m) of...

The fact is that output volatility and carbon dioxide (CO2) emissions move together over the period. This empirical study examines the dynamic effect of output volatility on CO2 emissions using the advance nonlinear panel autoregressive distributed lag (ARDL) approach. The empirical analysis is executed for ten high emitters Asian countries coverin...

The establishment of protected areas (PAs) is an effective and prevailing tool for conserving wetlands globally, however, strong evidence indicates that not all PAs can deliver adequate conservation to wetland ecosystems due to the impacts of natural and anthropogenic factors. Many studies have used multiple indices to assess the conservation effec...

Fecal bacteria contaminate water resources and result in associated waterborne diseases. This study assessed drinking water quality and evaluated their potential health risks in Swat, Pakistan. Ground and surface drinking water were randomly collected from upstream to downstream in the River Swat watershed and analyzed for fecal contamination using...

Gestational diabetes mellitus (GDM) is a disease with hyperglycemia, insulin resistance and fetal abnormality development. This study was designed to evaluate the hypoglycemic effect and hepatoprotective properties of olive leaves extract.The experimental mice divided into not diabetic group, the control group (GI), and the diabetic pregnant mice w...

The alpine region of the Greater Himalayas is rich in terms of biodiversity with high endemism, and at the same time supports livelihood of the indigenous peoples and of massive downstream populations. However, the alpine environments are among the habitats most vulnerable to environmental change. Of the alpine regions, these Himalayas are experien...

The non-degradable nature of plastic bags is posing a wide range of serious environmental and health deteriorations and hence are considered to be a big problem in waste management. This study was carried out to determine the popularity, usage, disposal and environmental impacts of plastic bags in Mingora city District Swat, Khyber Pakhtunkhwa Nort...
