The study evaluated eight heavy metals content and soil pollution from agricultural soils in northern China. Multivariate and geostatistical analysis approaches were used to determine the anthropogenic and natural contribution of soil heavy metal concentrations. Single pollution index and integrated pollution index could be used to evaluate soil heavy metal risk. The results show that the first...

Monitoring of leachate quality is the essential measure in aftercare for evaluating landfill stabilization. Generally, the most common way of leachate monitoring is executed at the inlet of the leachate treatment facility. However, it does not necessarily reflect the actual state of the site. Thus, methodologies which focus on both the discharge, in order to determine when the post-closure care...

The retention of foetal membranes (RFM) is supposed to be related to oxidative stress which can be evaluated through indirect and direct parameters, among others, total antioxidant capacity (TAC) and lipid peroxidation intensity (LPI). Placental samples (maternal and foetal parts) were collected from Holstein-Friesian healthy cows immediately after caesarean section (n = 13, group A) at time or...

After washing and curing, P is transported from the phosphogypsum to leachate during detoxification process, providing two ideas for phosphorus recovery leachate: 1) preparation of calcium hydrogen phosphate feed; 2) phosphate. A ready-to-use oxide slurry was used recover at a concentration 20% quantitative link between ratio fixation rate fitted by mixed use batch experiments, reaction kinetic...

BACKGROUND Pulmonary alveolar proteinosis (PAP) is a syndrome with multiple etiologies and is often deadly in lysinuric protein intolerance (LPI). At present, PAP is treated by whole lung lavage or with granulocyte/monocyte colony stimulating factor (GM-CSF); however, the effectiveness of GM-CSF in treating LPI associated PAP is uncertain. We hypothesized that GM-CSF and surfactant protein D (S...

OBJECTIVE Little is known about the magnitude and consequences of violence against children for those living outside family care. We sought to estimate the frequency of childhood abuse and examine its association with lifetime pregnancy involvement (LPI) and past year suicide ideation among orphaned youth. METHODS We analyzed data collected via cross-sectional interviewer-administered surveys...

The performance of three constructed wetland systems treating landfill leachate, two located in northern Poland (Szadółki near Gdańsk and Gatka near Miastko) and one in southern Sweden (Örebro), is discussed. The CWs differ in size, hydraulic regime, type of hydrophytic plants, and type of leachate pre-treatment before discharging to the CW. The CW in Szadółki consists of two parallel beds with...

Five landfills were analyzed to provide a perspective of current practice and technical issues that differentiate bioreactor and recirculation landfills in North America from conventional landfills. The bioreactor and recirculation landfills were found to function in much the same manner as conventional landfills, with designs similar to established standards for waste containment facilities. L...
