Some relationships between economic development and pollutant discharge have been found to be represented by inverted U-shaped curves, namely the environmental Kuznets curve (EKC), while S-shaped and N-shaped curves have also been found. There are several hard and soft measures to improve water quality in the rivers in Southeast Queensland. Socio-economic conditions related to river water envir...

BACKGROUND There is growing concern of health effects of exposure to pollutant mixtures. We initially proposed an Environmental Risk Score (ERS) as a summary measure to examine the risk of exposure to multi-pollutants in epidemiologic research considering only pollutant main effects. We expand the ERS by consideration of pollutant-pollutant interactions using modern machine learning methods. We...

Arsenic and antimony are toxic metalloids and are considered priority environmental pollutants by the U.S. Environmental Protection Agency. Significant advances have been made in understanding microbe-arsenic interactions and how they influence arsenic redox speciation in the environment. However, even the most basic features of how and why a microorganism detects and reacts to antimony remain ...

• A review of electrocoagulation for a range pollutants. Electrode processes depend upon the electrode material. pollutant removal mechanisms can occur. Emerging challenges are system design and modeling. Electrocoagulation (EC) electrocoagulation-flotation (ECF) widespread interest owing to their effectiveness simultaneous abatement broad pollutants in drinking waste waters, but capability var...

BACKGROUND Previous epidemiologic studies have considered the effects of individual air pollutants on birth outcomes, whereas a multiple-pollutant approach is more relevant to public health policy. OBJECTIVES The present study compared the observed effect sizes of prenatal fine particulate matter (PM2.5) and polycyclic aromatic hydrocarbons (PAH) (a component of PM2.5) exposures on birth outc...

Human activity today produces a large number of pollutants that end up in the environment, such as soil, water, and airborne particles. The first objective this work is to introduce new third-order multivariate calibration approach called self-weighted alternating quadrilinear decomposition (SWAQLD) for analysis organic pollutant fluorene (FLU) different water systems. One simulated two real fo...

The production of hydrogen accompanied by the simultaneous oxidation of arsenite (As(III)) was achieved using an electrochemical system that employed a BiOx-TiO2 semiconductor anode and a stainless steel (SS) cathode in the presence of sodium chloride (NaCl) electrolyte. The production of H2 was enhanced by the addition of As(III) during the course of water electrolysis. The synergistic effect ...

BACKGROUND Surfactant protein A (SP-A) enhances phagocytosis of bacteria, including Klebsiella pneumoniae, by alveolar macrophages. Ozone, a major air pollutant, can cause oxidation of surfactant and may influence lung immune function. Immune function may also be affected by sex-specific mechanisms. We hypothesized that ablation of SP-A has a negative impact on the susceptibility of mice to Kle...
