Abstract:
An oral dose of 1000 mg/kg body weight/day is mentioned in Organisation for Economic Cooperation and Development (OECD) and European Union (EU) guidelines as a default maximum dose in limit tests for studies on reproductive toxicity. This paper investigated whether upper range human exposure data from the workplace are supportive of this limit dose as an upper limit of possible human exposure. To this end, published exposure data as well as data from the database MEGA of the German “Berufsgenossenschaften” were evaluated. These data indicate that exposure concentrations in the range of 500 to

Abstract:
Abstract South African occupational exposure limits for hazardous chemical agents were revised in 2021 and introduced some limit values that were lowered by up to 99.2% when compared with the previously applicable limit values. A descriptive study was conducted as desk research to identify exposure limits from a list typically applicable to carcinogens, mutagens, teratogens, or sensitizers, called maximum limits, that were lowered substantially. The percentage reduction in maximum limits were calculated to identify those that were reduced by more than 50%, constituting more stringent limits. T

Abstract:
Abstract Occupational hygiene service providers and companies worldwide have been collecting thousands of exposure monitoring samples and not leveraging the lessons learned from exposure monitoring results. The exposure monitoring results are often not representative of actual exposures. Precious resources are wasted in collecting exposure monitoring samples when not needed based on, for example, previous exposure monitoring results and chemical properties. For example, inhalation of phosphoric acid exposure is rarely a concern as phosphoric acid vapor pressure is low (0.03 mmHg (20 °C). Expos

Additionally, the performance of a combination of currently in service helmets and headsets were evaluated in accordance with the ANSI Standard S12.42. The hearing protection performance results were used in combination with the measured sound pressure levels to evaluat

Abstract:
Flight testing has been performed on a Royal Canadian Air Force (RCAF) CH-147F Chinook helicopter to investigate aircrew whole-body vibration (WBV) exposure levels in accordance with ISO 2631-1 or MIL-STD-1472G standard. Results showed that the helicopter cabin vibration was dominated at the N/rev harmonics of the three-bladed tandem rotor speed. The aircrew WBV levels varied significantly depending on flight conditions and aircraft load configurations while the highest levels of WBV occurred at high speed level flight maneuver conditions. With reference to the guidelines in the standards, the

Abstract Hydrogen Sulfide is an objectionable gas which when released is highly corrosive on contact with both metal and concrete surfaces. The generation of this gas therefore presents a multitude of problems in the daily generation of waste products in industry, food production and municipal waste treatment.; In addition to the problem experienced with corrosion is the health and safety issue of exposure to this dangerous gas. Hydrogen Sulfide has an objectionable odor on initial contact; it is a toxic gas to humans and animals, which will rapidly react to cause serious health problems.; Reg

Abstract:
Abstract Coatings form an integral part of the corrosion protection system of oil and gas pipelines that are often operating under high mechanical stress and corrosive environmental conditions. It is necessary to assess coatings for potential loss of integrity, such as mechanically induced holidays and cracks, before they are put into operation. The standard method of assessing coating’s behavior and flexibility under mechanical strain is the mandrel bending test, wherein high voltage holiday test is normally used to determine the existences of discontinuities in coating films.

Abstract Amine reclaimer column is utilized to remove oxozolidone (amine degradation product) from lean amine solution containing sulfolane, diisopropanol amine (DIPA), water, acid gas (H2S and CO2), and oxozolidone. Inside the column, the lean amine solution is heated by medium pressure steam. Vapor containing H2S and CO2 and amine leave the top of the column. While oxozolidone remain in the liquid phase leaves the column from bottom outlet piping. The reclaimer system was operated continuously, irrespective of the limit of oxozolidone content which is not as per design specification. Therefo

Abstract:
This research presents a methodology to assess the health and environmental impacts from thermal runaway events in outdoor, large-scale, Li-ion BESS units. Through application of the methodology, a relationship between exposure limit distance and wind speed, ambient temperature, event duration, cell chemistry, and toxic gas species can be established. This study did not consider other health factors, such as thermal exposure. The methodology involves a literature review to aggregate data, plume dispersion modeling, and a risk analysis of the model results.

Abstract:
We study Puerto Rico’s experience after the severe hurricane season of 2017 to better understand how extreme weather disasters affect bank stability and their ability to lend. Despite the devastation wrought by two category 5 hurricanes in a single month, we find relatively modest and transitory impacts on bank performance with no evident decline in lending capacity. We discuss various mitigants that help limit bank exposure to extreme weather and whether these mitigants may be vulnerable given the potential for more severe and more impactful climate events.

Abstract:
During the Summer and Autumn of 2023, Lough Neagh in Northern Ireland was affected by a cyanobacterial bloom. Testing of water from within the bloom reported high concentrations of one type of cyanobacterial toxin, microcystins. Samples were taken from the Lough of eels, roach, perch, pollan and bream and tested for a range of cyanobacterial toxins, including microcystins, nodularins, anatoxin, cylindrospermopsin and saxitoxin. Each sample comprised 10 fish, and five samples were taken of each species, except for bream for which a single sample was collected. The fish were dissected and the ed

In Thailand, oxytetracyline (OTC) has been used in the protection and treatment of infected shrimps. The misuse of OTC could lead to OTC residues in shrimps destined for consumption. To prevent consumers from exposure to drug residues and increase of drug resistance pathogens, several food safety authorities in many countries have set the maximum residue limits (MRLs) for OTC and enforced the surveillance detection programs. Therefore, an effective screening method is essential to detect OTC residue in food. Enzyme-linked immunosorbent assay (ELISA) is the suitable methods for screening a larg

This study builds upon prior research by conducting thirteen experiments in three-story, multi-family dwellings to quantify the impact of coordination between ventilation and suppression actions. Experiments were conducted in four, garden-style apartment buildings; each of which had two lower-level units, four first-floor units, and four second-floor units.

Abstract:
The inert fluorescent dye rhodamine water tracer (RWT) has been widely used in freshwater aquatic systems for many years to quantify bulk water exchange patterns and as a tracer for submersed herbicide movement. The dye is well-suited for tracer work due to its high solubility and detectability in water (&lt;0.01 μg/L). Federal guidelines limit the aqueous concentration 0f RWT to &lt;10 μg/L at drinking water intakes. The dye has proven to be harmless to aquatic organisms and humans in low concentrations and is relatively inexpensive. Since 1991, RWT has been used by Engineer Re-search and Dev
