Adsorbable organic halogen is a mean to quantify total organic halogen, which is an important toxicity indicator in disinfection byproduct studies. However, quantification of low concentrations of adsorbable organic chlorine (AOCl) formation in seawater chlorination using the USEPAMethod 9020Bwas found inaccurate due to the presence of high concentrations of chloride. In this study, a dialysis-based pretreatment techniquewas proposed, optimized and adopted to eliminate the interference of chloride in quantifying low concentrations of AOCl inseawater. A volumetric ratio of dialysis samples to continuous-flow deionized water at 1:1200 was found sufficient to remove over 99% of chloride. As a result, chloride to …

Adults with intellectual disabilities (ID) typically have a sedentary lifestyle and higher rates of overweight and obesity. This study describes the habitual daily physical activity (PA) and the health-related physical fitness (PF) of adults with mild and moderate ID who resided in four group homes and worked in sheltered workshops. We also assessed the contribution of PF variables towards PA levels and sedentary behavior of this population subgroup. Adults with mild and moderate ID (N = 114) were assessed on PF tests (percent body fat, waist and hip circumferences, 6-min walk (6MWT), arm curl, and sit and reach). PA and …
