    July 2014 ENVIRONMENTAL IMPACT ASSESSMENT FOR SASOL PSA AND LPG PROJECT TERRESTRIAL FAUNA IMPACT ASSESSMENT Specialist Report 10 OOD OF MARK WOOD CONSULTANTS SSOCIADOS MOZAMBIQUE LDA PREPARED BY Author: AR Deacon Submitted to: EIA CONDUCTED BY GOLDER A WITH EIA LEADERSHIP BY MARK W SASOL Petroleum Mozambique Limitada & Sasol Petroleum Temane Limitada Report Number: 1302793 - 10712 - 20 (Eng) TERRESTRIAL FAUNA NON TECHNICAL SUMMARY Introduction Sasol Petroleum Mozambique (SPM) and Sasol Petroleum Temane (SPT) are proposing to develop the PSA Development and Liquefied Petroleum Gas (LPG) Project, situated near Inhassoro in the Inhambane Province of Mozambique. The project is an expansion of the existing Sasol Natural Gas Project in this area. Proposed new infrastructure includes 19 wells (oil and gas), associated flowlines and a new Manifold Station (8.8 ha), from which the oil flowlines will be combined into a single pipeline routed to the new Integrated PSA Liquids and LPG Plant (9.5 ha), constructed adjacent to the Central Processing Facility (CPF). This Study This study presents the findings of an assessment of the impact of the project on Terrestrial Fauna. It is one of a series of studies prepared for the Environmental Impact Assessment for the project. The study takes into account Mozambique laws and regulations, regional conventions and protocols and importantly, the Performance Standards of the International Finance Corporation, in particular Performance Standard 6, Biodiversity Conservation and Sustainable Management of Living Natural Resources, as the underpinning of the assessment and the recommendations made in the report. Methodology The survey made use of habitat availability in the different vegetation types, while the presence of observed species was used as an indicator of habitat integrity.

  • Protein Expression in Mammalian Cell Lines After Lowlevel Metal Exposure
    Montana Tech Library Digital Commons @ Montana Tech Graduate Theses & Non-Theses Student Scholarship Spring 2021 PROTEIN EXPRESSION IN MAMMALIAN CELL LINES AFTER LOWLEVEL METAL EXPOSURE Sydney Jennings Follow this and additional works at: https://digitalcommons.mtech.edu/grad_rsch PROTEIN EXPRESSION IN MAMMALIAN CELL LINES AFTER LOW- LEVEL METAL EXPOSURE by Sydney Jennings A thesis submitted in partial fulfillment of the requirements for the degree of Interdisciplinary Masters of Science Montana Tech 2021 ii Abstract Mining in Butte, Montana has been ongoing since the mid-19th century. The US Environmental Protection Agency (EPA) added the Butte Area to the National Priority List in 1983, designating it a Superfund site. Butte is currently part of the largest EPA Superfund site in the United States. The EPA lists arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) as metal contaminants of concern for residents living in proximity to the Butte Area Superfund site. However, very limited human biomonitoring has been conducted in Butte and studies that have been published focus on Pb and, to a lesser extent, As. No synergistic, antagonistic, or additive studies have been conducted, even though it is widely accepted that the exposure in Butte is a metal mixture scenario, rather than single element exposure. Metals that are trace micronutrients, such as copper (Cu), manganese (Mn), and zinc (Zn) have been largely unrecognized as possibly having negative health effects on residents of Butte, despite the fact the metals have been historically released into the soil, water, and air through active blasting and crushing of ore and are known to be potential neurotoxins.

    ZIMBABWE ZAMBIA MALAWI SPECIES CHECKLIST AFRICA VEGETATION MAP BIOMES DeserT (Namib; Sahara; Danakil) Semi-deserT (Karoo; Sahel; Chalbi) Arid SAvannah (Kalahari; Masai Steppe; Ogaden) Grassland (Highveld; Abyssinian) SEYCHELLES Mediterranean SCruB / Fynbos East AFrican Coastal FOrest & SCruB DrY Woodland (including Mopane) Moist woodland (including Miombo) Tropical Rainforest (Congo Basin; upper Guinea) AFrO-Montane FOrest & Grassland (Drakensberg; Nyika; Albertine rift; Abyssinian Highlands) Granitic Indian Ocean IslandS (Seychelles) INTRODUCTION The idea of this booklet is to enable you, as a Wilderness guest, to keep a detailed record of the mammals, birds, reptiles and amphibians that you observe during your travels. It also serves as a compact record of your African journey for future reference that hopefully sparks interest in other wildlife spheres when you return home or when travelling elsewhere on our fragile planet. Although always exciting to see, especially for the first-time Africa visitor, once you move beyond the cliché of the ‘Big Five’ you will soon realise that our wilderness areas offer much more than certain flagship animal species. Africa’s large mammals are certainly a big attraction that one never tires of, but it’s often the smaller mammals, diverse birdlife and incredible reptiles that draw one back again and again for another unparalleled visit. Seeing a breeding herd of elephant for instance will always be special but there is a certain thrill in seeing a Lichtenstein’s hartebeest, cheetah or a Lilian’s lovebird – to name but a few. As a globally discerning traveller, look beyond the obvious, and challenge yourself to learn as much about all wildlife aspects and the ecosystems through which you will travel on your safari.
