Health Effects Of Neonicotinoids On An Agricultural Community, Jocelyn Rodriguez-Paar

Capstone Experience: Master of Public Health

Mead, Nebraska, a small United States agricultural community consisting of approximately 600 people, was accidentally exposed to high amounts of neonicotinoids when AltEn, an ethanol plant that used neonicotinoid coated corn and soybean seeds for biofuel, was discovered not disposing of the toxic byproduct safely. Coincidentally, there was also a leak in their wastewater system that also contaminated the nearby areas. Although neonicotinoids are not considered highly dangerous with low dose exposures, large dose exposures can cause symptoms similarly to nicotine poisonings, such as difficulty breathing, vomiting, nausea, hypertension, tachycardia, and lethargy (Imamura, T. et al., 2010). Neonicotinoid poisoning can …

The Influence Of Acidification And Copper Exposure On Copper Accumulation And Anti-Oxidant Enzyme Responses In The Pond Snail, Lymnaea Stagnalis, Gretchen K. Bielmyer-Fraser, Francis Alip, Ruth Adeyemi, Nolan Carney, Fasinia Santiago, Kyla Siemen, Kiley Donaghy

Georgia Journal of Science

Atmospheric carbon dioxide is rising at an accelerated rated due to increased anthropogenic activities. Metals have also been a noted problem; however, little research has addressed combined exposure of both pollutants to sensitive, calcifying organisms in freshwater habitats. This study examined copper accumulation (over 7 d) and activity of the antioxidant enzymes, catalase and glutathione peroxidase (over 2 d), in the freshwater common pond snail, Lymnaea stagnalis, after exposure to ambient and increased (2000 µatm) CO₂ and copper (control, 5, and 20 µg/L). Results demonstrated increased copper accumulation in soft tissue of snails exposed to copper; however, exposure to …

Chemical Poisoning In Animals. 1. Arsenic, H D. Seddon

Journal of the Department of Agriculture, Western Australia, Series 4

ARSENIC is poisonous to all animals and to man in quite small amounts and exposure to poisoning is often a result of human carelessness.

It is present in many chemical dips used for control of insect parasites on stock, and in agricultural fruit sprays and weed killers whose relative cheapness makes their use economical.

However, their potential danger and the economic loss they may cause are a disadvantage.

Bracken Poisoning In Cattle, P B. Lewis

Journal of the Department of Agriculture, Western Australia, Series 4

THE ingestion of bracken fern causes the death of numbers of young cattle in the South-West of Western Australia every year.

Early experimental work in the United Kingdom demonstrated that bracken contained an anti-Vitamin Bl factor called thiaminase which was thought to be the cause of the poisoning, but later work indicated that a bone marrow poisoning, not yet chemically identified, was responsible.

Lupinosis, H W. Bennetts

Journal of the Department of Agriculture, Western Australia, Series 4

LUPINOSIS is a disease which has caused severe mortalities in West Australian sheep flocks in recent years, and one which—because of the important role which lupins are playing in light land development—must inevitably continue to be a matter of serious concern.
