Road deposited sediment (RDS) is regarded as sinks for metal pollutants derived from road-traffic that may pose a danger for the nearby water environment. The reported study aims to analyse RDS build-up and associated metal emission patterns using Riccarton Campus of Heriot Watt University,...

Monitoring and assessment of fresh water has become an environmental concern due to the contamination by human kind, thereby decreasing the suitability of the fresh water. The Kukshet Lake, which is the study area of the present investigation receives domestic raw sewage from surrounding...

China is an emerging and leading world economy. The pace of economic change has been tremendously rapid since the beginning of economic reforms. Despite the importance of the Environmental Kuznets Curve (EKC) and environmental problems in China, no previous study has tested the EKC in China...

This study focused on the removal of Pb(II), Cd(II), Cu(II), and Zn(II) using reagent solutions by natural limestone in a batch system. The sorbent, collected from the Late Cretaceous limestone beds, Tunisia, was characterised by X-ray diffraction (XRD), chemical analysis (XRF) and infrared...

Dissemination of information to decision-makers and enhanced methods of public participation are often put forward as antidotes to a perceived disconnect between risk assessment and risk communication in the public domain. However, mechanisms that support both the provision of routine, timely...

Statistical investigation on groundwater arsenic concentration data of southwest Bangladesh was performed. Two data sets of 1998-99 and 2002-03 were selected for this analysis. Summary statistics of the data shows that the mean concentration exceeds the Bangladesh limit (0.05 mg/l) in all areas....

The Environmental Kuznets Curve (EKC) has become an accepted standard for describing the relationship between economic growth and environmental degradation. However, the available evidence based on the EKC for water is ambiguous and it varies depending on the sets of countries selected for the...

In the present investigation, different agricultural solid wastes namely: eggplant hull (EH), almond green hull (AGH), and walnut shell (WS), that are introduced as low cost adsorbents, were used for the removal of heavy metals (cobalt, strontium and mercury ions) from aqueous solutions....
