An effective approach for control of internal nutrient loading and sediment hypoxia remains a longstanding challenge to the restoration aquatic ecosystems. In order simultaneously tackle these issues, MultiFunction Geoengineering material (MFG) was developed remediation through synergistic functions physical capping, adsorption delivery O2 nanobubbles. The MFG, derived from natural zeolite, exh...

The study area, Nagadeepa is situated in Badulla District within the dryer parts of country. Groundwater main drinking water source area. was carried out from 2013 to 2016 and objective examine chemical status pollution levels by examining 25 quality parameters namely Na+, K+, Mg2+, Ca2+, Pb Mo, Cr, Cd, Mg, Hg, As, Al, Zn, Se, Cl-, F-, NO3-, HCO3-, SO42-, PO43-, DO, pH, temperature, electrical ...

Effects of wastewater discharge on the coastal area in Gaza strip Palestine are not fully investigated. This study investigated effect physical and chemical properties marine water over a period 2 year. Sea sediment samples were collected from about 20 different sites. The sediments wastewater/sea mixing zone at depth 0, 2.5 5 m column direct discharging pipe line location similarly other locat...

It is counterintuitive that invertebrate shells can induce bone formation, yet nacre, or mother of pearl, from marine shells is both osteoinductive and osteointegrative. Nacre is composed of aragonite (calcium carbonate) and induces production of vertebrate bone (calcium phosphate). Exploited by the Mayans for dental implants, this remarkable phenomenon has been confirmed in vitro and in vivo, ...

The study was conducted to spatiotemporally analyze the quality, location and critical water variables influencing quality using monitoring data from Department of Environment Natural Resources, Dong Thap province in 2019. parameters including turbidity, pH, temperature, dissolved oxygen (DO), total suspended solids (TSS), biological demand (BOD), chemical (COD), nitrite (N-NO2?), nitrate (N-NO...

Effluent ‘Coda’ originating from palmyrah toddy distillery units is the major source of environmental pollution in the Jaffna district of Sri Lanka. Spent wash produced from distilleries is rich in organic material and characteristically less toxic. A research was carried out to find the optimal dilution factor of the effluent before discharge through construction of wet lands which is a new, e...
