This study examined the effects of waste container handling on surface electromyographic activity of the erector spinae, infraspinatus and upper trapezius muscles, trunk kinematics (position, velocity and acceleration) measured in three planes (lateral, sagittal and transverse), spinal loading at the L5/S1 region and low back disorder (LBD) risk. Eleven field technicians at the Lawrence Livermore National Laboratory (LLNL) were asked to manipulate 30 and 55 gallon waste drums and carry a 5 gallon carboys in their workplace. Results showed that there was a statistically significant difference in muscle load on the erector spinae during drum handling activities. Loading and unloading the 55-gallon drums required more force from all muscle groups than the 35-gallon drums. Muscle peak load did not show a significant difference between 35 and 55 gallon drum rolling. For carboy transport, peak muscle activity is greater for all muscle groups with the two carboy carry. The calculated LBD risk also recognized the same activities as being most "at risk." This data was used by the participatory team to focus their interventions and determine handling limits.

EFFECTS OF ULTRA-LOW VOLUME APPLICATIONS OF MALATHION IN HALE COUNTY, TEXAS. 2 MOSQUITO POPULATIONS IN TREATED AND UNTREATED AREAS

The effects of ultra-low volume (ULV) aerial applications of technical malathion at the rate of 214 g/ha (3 oz. per acre) on mosquito populations was evaluated in 3 Hale County, Texas towns during June through August, 1967. Light trap and sentinel shed trap indices were used to follow trends in adult mosquito population fluctuations in the treated towns and in I untreated town and selected rural sites. Four species,Aedes nigromaculis(Ludl.),Aedes vexans(Meig.),Gulex tarsalisCoq., andPsorophora signipennis(Theob.), made up 99% of the mosquitoes collected in light traps. Only 3 species,A. vexans, C. tarsalis, andGulex pipiens quinquefasciatusSay, were commonly collected in chicken-baited sentinel shed traps. An evaluation of the effects of ULV aerial treatments with malathion on mosquito populations was made by comparing pre- and post-treatment population indices. These comparisons indicated that lasting mosquito control was not achieved. Although Substantial reductions were some times obtained by treating, there was evidence thatG. tarsalispopulations in Plainview returned to their pre-treatment levels by the third day following treatment, and thatPsorophoraandAedesspp. did so by the fourth and fifth days, respectively. It was apparent also that mosquito populations built up and declined on a seasonal basis independently of the treatments. Infiltration of adult mosquitoes from outside the treated areas was postulated to account for the rapid post-treatment population build-ups.

Two complementary field sampling methods for the determination of residual aviation gasoline content in the contaminated capillary fringe of a fine, uniform, sandy soil were investigated. The first method featured field extrusion of core barrels into pint-size Mason jars, while the second consisted of laboratory partitioning of intact stainless steel core sleeves. The barrel extrusion procedure involved jar headspace sampling in a nitrogen-filled glove box, which delineated the 0.7m thick residually contaminated interval for subsequent core sleeve withdrawal from adjacent boreholes. Soil samples removed from the Mason jars (in the field) and sleeve segments (in the laboratory) were subjected to methylene chloride extraction and gas chromatographic analysis to compare their aviation gasoline content. The barrel extrusion sampling method yielded a vertical profile with 0.10m resolution over an essentially continuous 5.0m interval from the ground surface to the water table. The sleeve segment alternative yielded a more resolved 0.03m vertical profile over a shorter 0.8m interval through the capillary fringe. The two methods delivered precise estimates of the vertically integrated mass of aviation gasoline at a given horizontal location, and a consistent view of the vertical profile as well. In the latter regard, a 0.2m thick lens of maximum contamination was found in the center of the capillary fringe, where moisture filled all voids smaller than the mean pore size. The maximum peak was resolved by the core sleeve data, but was partially obscured by the barrel extrusion observations, so that replicate barrels or a half-pint Mason jar size should be considered for data supporting vertical transport analyses in the absence of sleeve partitions.

Molecular insight of dissolved organic matter and chlorinated disinfection by-products in reclaimed water during chlorination with permanganate preoxidation

Permanganate is a common preoxidant applied in water treatment to remove organic pollutants and to reduce the formation of disinfection by-products. However, the effect of permanganate preoxidation on the transformation of dissolved effluent organic matter (dEfOM) and on the formation of unknown chlorinated disinfection by-products (Cl-DBPs) during chlorination remains unknown at molecular level. In this work, the molecular changes of dEfOM during permanganate preoxidation and subsequent chlorination were characterized using Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Permanganate preoxidation was found to decrease the DBE (double bond equivalent) and AImod (modified aromaticity index) of the dEfOM. The identity and fate of over 400 unknown Cl-DBPs during KMnO4-chlorine treatment were investigated. Most Cl-DBPs and the precursors were found to be highly unsaturated aliphatic and phenolic compounds. The Cl-DBPs precursors with lower H/C and lower O/C were preferentially removed by permanganate preoxidation. Additionally, permanganate preoxidation decreased the number of unknown Cl-DBPs by 30% and intensity of unknown Cl-DBPs by 25%. One-chlorine-containing DBPs were the major Cl-DBPs and had more CH2 groups and higher DBEw than Cl-DBPs containing two and three chlorine atoms. 60% of the Cl-DBPs formation was attributed to substitution reactions (i.e., +Cl–H, +2Cl–2H, +3Cl–3H, +ClO–H, +Cl2O3–2H). This work provides detailed molecular level information on the efficacy of permanganate preoxidation on the control of overall Cl-DBPs formation during chlorination. © 2023 Elsevier Ltd

Comparison of ZnO Doped Different Phases TiO2 Nanoparticles in Terms of Toxicity Using Zebrafish (Danio Rerio)

作者： Sezer, Selda Yücel, Ayşegül Turan, Duygu Özhan Emre, Fatma Bilge Sarikaya, Musa Malatya Turgut Ozal University Akcadag Vocational School Laboratory and Veterinary Health Program Akcadag Malatya Turkey Iskenderun Technical University Iskenderun Vocational School Environmental Protection and Control Program Hatay Iskenderun Turkey Inonu University Faculty of Engineering Department of Mining Engineering Malatya Turkey Inonu University Faculty of Arts and Science Department of Biology Malatya Turkey Inonu University Faculty of Education Department of Science Teaching Malatya Turkey

Titanium dioxide is used in many commercial and industrial areas such as paint, paper, cosmetics, textiles, and surface coating. The reasons for its use in such a wide area are its anti-corrosion and high stability. Although TiO2 is considered to be a low toxicity material, research has been further expanded following the recognition of the possible carcinogenic effects of TiO2 in humans by the International Agency for Research on Cancer (IARC). The aim of this study is to compare the toxicity of TiO2 used in many fields in different phases. In the study anatase TiO2 synthesized by hydrothermal method and dual phase TiO2 (anatase and rutile phase) structures obtained by thermal conditioning were used and compared with commercially available TiO2. ZnO which has similar uses like TiO2 was also used and compared with 1% doped TiO2 in different phases in terms of toxicity. Zebrafish (Danio rerio, D. rerio), a freshwater fish, which is widely used in toxicity assessments was preferred in this study due to its small size, fast reproduction rate, low cost, physiological and molecular similarity with humans, and genetic predisposition. Experimental investigations showed that the highest death occurred in the low concentrations of (10 ppm) ZnO doped rutile phase. 39% of the embryos died in the ZnO nanoparticle solutions prepared at low concentrations. The highest mortality at medium (100 ppm) and high (1000 ppm) concentrations were observed in the ZnO-doped rutile phase after 96 hours. Similarly, the highest malformation was detected in the ZnO-doped rutile phase during the same period. © 2022, The Authors. All rights reserved.
