Excess suspended particulate matter (PM) in constructed wetland (CW) substrates may reduce the substrate porosity and thus affect pollutant removal performance. However, it remains unclear how different PMs nitrogen performance CWs. In this study, kaolin polystyrene (PS) were selected as two model added to CW at a concentration of 100 mg/L. Four CWs constructed, designated C-CW without PM addit...

The objective of this study was to measure particulate matter (PM) total loss rates in three older (1940s, 1960s, and 1980s) elevators California during two phases low-cost intervention modes. Tracer gas decay <2 μm aerodynamic diameter nontoxic NaCl particles (PM2) were used calculate PM2 rates. considered surrogates for smaller carrying SARS-CoV-2. Empirical paired with modeled dynamic sce...

Background & Aims of the Study: Particulate matters less than 10 microns can absorb into your lungs and reacting with the moisture and enter the circulatory system directly through the airways. The aim of this study is to assess Behavior PM 10 data in different seasons and Determination effects on human health in Ahvaz city during 2013. Materials & Methods: Data Particulate matters less than 10...

This study investigated the use of ceramic membranes to remove total suspended solids (TSS), organics (expressed by chemical oxygen demand, COD), and bisphenol A (BPA) via microfiltration (MF, pore size 0.45 μm) and ultrafiltration (UF, cutoff 150 kDa) in post-treatment of effluents from aerobic granular sludge reactors (GSBRs). The efficiency of removal of COD, BPA, and TSS in MF was similar t...

In this study, we investigated the physiological responses and particulate matter (PM) abatement adsorption of three plants: Ardisia crenata, japonica, Maesa to determine their effectiveness as indoor air purification. When compared control (without plants), PM was significantly rapidly decreased by all plants. The reduction in varied species, with A. crenata being most effective, followed clos...

Particulate matter (PM) pollution has become a serious threat to human health. Accordingly, an air filtration media that can efficiently remove particulate should be developed immediately. Nanofibrous membrane filter prepared by electrospinning technology nanoscale diameter, high specific surface area, and relatively porosity, which are suitable for dust removal. This paper explored the effects...

[1] Transformation processes in the euphotic and mesopelagic zones are of crucial importance to the biological pump and global elemental cycles. In this study, elemental stoichiometries and chemical compositions of particulate and dissolved organic matter (DOM) were investigated in the euphotic and upper mesopelagic zones of the North Pacific Subtropical Gyre. The distributions of bacterial bio...
