Toxicity and Neurotoxic Effects of Monoterpenoids: In Insects and Earthworms Abstract The insecticidal activity of several monoterpenoids from essential oils was evaluated against insect pests. Toxicity tests illustrated the bioactivity of d-limonene, α-terpineol, β-myrcene, linalool, and pulegone against insects, including the house fly, the German cockroach, the rice weevil, and the western corn rootworm. Bioassays were conducted to assess their toxicity via topical application, fumigation, ingestion, and ovicidal exposures. Growth, reproduction and repellency were also evaluated in the German cockroach. Non-invasive electrophysiological recordings were used with an earthworm to investigate neurotoxic effects of the monoterpenoids. Relevant monoterpenoid bioassay results in the literature are also discussed.

62570 APP Determ of DMDS and DMTS Water
APPLICATION NOTE Gas Chromatography Author: Kira Yang PerkinElmer Inc. Shanghai, China Determination of Low Levels of Dimethyl Disulfide (DMDS) and Introduction Continued urbanization and Dimethyl Trisulfide (DMTS) in industrialization throughout the world have brought the problem Water Using HS Trap-GC/FPD of malodor pollution into the forefront of many discussions on environmental sustainability and protection. Volatile organic sulfur compounds (VOSCs) have been identified as a primary contributor to malodor pollution in water, and are considered a serious safety and environmental threat, owing to the potential toxicity of compounds such as methyl mercaptan, ethanethiol, dimethyl sulfide (DMS), dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS), methyl phenyl sulfide, carbon disulfide, carbonyl sulfide and hydrogen sulfide (H2S). DMDS and DMTS are commonly found in urban sewage, and are formed by the conversion of sulfate through microbial reduction during the sewage transportation processes.1 Recognized as one of the main malodor contributors in urban sewage, DMDS and DMTS produce a “swampy” smell in sewage, akin to odors related to decaying cabbage or garlic. Water sources contaminated with trace amounts of DMDS and DMTS also result in an unpleasant odor and taste, causing concern and complaints amongst consumers. Thus, the determination and abatement of these VOSCs in water is drawing increasing attention amongst utility providers, water treatment plants and regulators alike. Table 1. Analytical parameters.

Issue n° 2 MAY 2019 In this issue----- ABACUS project in brief… - ABACUS project in brief The 3-year ABACUS project aims to provide a range of new molecules - Focus on WP1 & WP2 synthetized from microalgae and therefore to bring competitive innovative ingredients based on terpenes for fragrances markets and - Events of interest carotenoids for cosmetics and nutraceutics markets. The concept of ABACUS project associates several interdisciplinary approaches in order to support a high- value product market development stemming from: - Selection and biological engineering of microalgal strains and oriented photosynthesis of terpenoids; - Technological development of algae biomass production systems to optimize cultivation and photosynthesis of terpenoids; - Technological development of the downstream processing steps to reduce time and costs, and to optimize environmental acceptability; - Market development based on new algae-derived ingredients and structuration of new bio-based value chains. To reach its targets, ABACUS takes benefits from a wide range of expertise by gathering 2 large industrial partners (Proteus and Sensient Cosmetics Technologies), 3 algae SMEs (Algafuel, Microphyt and Subitec) and 4 RTOs (CEA, SAMS, CSIC and KIT). Since May 2017, a cooperative work has unfolded between all consortium members whose work is distributed in 10 defined work packages, altogether tailored to reach the objectives by the end of the project. With this second issue of our project’s newsletter, we are pleased to introduce WP1 & WP2 achievements to date. Product and market Market survey acceptances & roadmap Applicability Algae selection Fractionation Process design Up scaling Communication Management Ethics requirements WP1: Solidification of market opportunities and products specifications Two market studies for terpenoid and carotenoid molecules were performed during the first three months of the project. -

History, Occurrence, and Uses Mosander extracted from the mineral lanthana a rare earth fraction, named didymia in 1841. In 1879, Boisbaudran separated a rare earth oxide called samaria (samarium oxide) from the didymia fraction obtained from the mineral samarskite. Soon after that in 1885, Baron Auer von Welsbach iso- lated two other rare earths from didymia. He named them as praseodymia (green twin) and neodymia (new twin) after their source didymia (twin). The name praseodymium finally was assigned to this new element, derived from the two Greek words, prasios meaning green and didymos meaning twin. Praseodymium occurs in nature associated with other rare earths in a rel- atively high abundance. It is more abundant than some common metals such as silver, gold, or antimony. The average concentration of this metal in the earth’s crust is estimated to be 8.2 mg/kg. -

All laboratory chemical use areas must maintain a work-area specific Chemical Hygiene Plan which conforms to the requirements of the OSHA Laboraotry Standard 29 CFR 19190.1450. Purdue University laboratories may use this document as a starting point for creating their work area specific CHP. Minimally this cover page is to be edited for work area specificity (non-West Lafayette laboratories are to place their own emergency, fire, and police telephone numbers in the space above) AND appendix K must be completed.

PURDUE CHEMICAL HYGIENE PLAN AWARENESS CERTIFICATION For CHP of: ______________________________ Professor, building, rooms The Occupational Safety and Health Administration (OSHA) requires that laboratory employees be made aware of the Chemical Hygiene Plan at their place of employment (29 CFR 1910.1450). The Purdue University Chemical Hygiene Plan and Hazardous Materials Safety Manual serves as the written Chemical Hygiene Plan (CHP) for laboratories using chemicals at Purdue University. The CHP is a regular, continuing effort, not a standby or short term activity. Departments, divisions, sections, or other work units engaged in laboratory work whose hazards are not sufficiently covered in this written manual must customize it by adding their own sections as appropriate (e.g. -

Effects of Intravenous Injections of Radium Bromide. by R
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PubMed Central EFFECTS OF INTRAVENOUS INJECTIONS OF RADIUM BROMIDE. BY R. BURTON-OPITZ AND GUSTAVE M. MEYER. (From the Laboratories of Physiology and Physiological Chemistry of Colum- bia University, at the College of Physicians and Surgeons, New York.) PLATE XVI. The present study was undertaken with a view of determining in a general way the effects of intravenous administration of ra- dium upon the circulation and respiration. The problem was sug- gested to us by Dr. William J. Gies, under whose guidance a number of researches, dealing with the more extensive question of the action of radium upon animal and vegetable cells, have re- cently been carried on in the laboratories of Columbia University.1 For the radium used in these experiments we are greatly in- debted to Mr. Hugo Lieber. It was supplied to us in the form of the bromide, in preparations of 240 , iooo, and io,ooo activities. The strength of the solution used was the same in all cases. It contained 45 rag. of the dry substance in 25 c. c. of the solvent; each cubic centimeter of the solution, therefore, contained 1.8 rag. of the radium preparation. The amount of the radium present varies directly with the ra- dio-activity. Preparations of ~,5oo,ooo activity are said to repre- sent pure radium bromide3 Taking this figure as the standard of purity, ~ .8 rag. of the radium preparation of io,ooo activity contained approximately only o.o~ 26 mg., the same quantity of the preparation of ~ooo activity contained o.ooi26 rag. -
