Environmental health & Toxicology Flashcards
Name two disease Asbestos can cause
Mesothelioma, lung cancer and asbestosis (a type of pneumoconiosis)
Who publishes guidelines for human vaccinations?
The Advisory Committee on Immunization Practices, CDC
What type of poisoning do alkaloid containing plants cause?
Liver damage
What type of poisoning does foxglove cause
Digitalis - nausea, diarrhoea and cardiac effects
List some of the direct health effects of climate change and population in greatest risk
Exposure to extreme temperatures (elderly), UV radiation (coastal, outdoor) , floods and wildfires.
List some of the indirect health effects of climate change and population in greatest risk
increase in vector borne and zoonotic diseases (populations at disease borders), respiratory disease due to changes in air quality (children, asthmatics, elderly), malnutrition due to food and water related effects (poor) and allergic diseases (children)
Most relevant climate sensitive mosquito borne diseases
Malaria, West nile virus, Chikungunya, Dengue
Name important tick borne climate sensitive diseases
Lyme borreliosis, tick-borne encephalitis, tularemia and Crimean Congo Hemorragic fever
Name important rodent borne climate sensitive diseases
Yersinia Pestis (plague), leptospirosis, hanta-virus
top three causes of death attributed to air pollution
- Stroke 2. Heart Attack and 3. Chronic Obstructive Pulmonary Disease(COPD)
Major health effects of Hurricanes
Drowning, Carbon monoxide poisoning, Displaced persons/animals, Power loss, Contaminated drinking water, Damaged/destroyed infrastructure, Non-functional clinics and hospitals, Affected medical and public health staf, Mold in homes and buildings
Health related issues impacted by power outage
mental health, temperature contorl, light, clean water, sewage disposal, food and medication storage, med tech/life support, safety mechanisms, transport, communication, air quality
Describe the 3+4 sections of public health emergency response
Monitoring and surveillance of mortality, shelters, syndromes and support for states. Communication to educate, advice, prevent, dissipate rumors - to partners, timely and accurately to public, monitoring news and social media. Environmental health - water safety, mold control, vector control and occupational health
Mold clean up guidelines
Protect your self, dry it in 24-48h with natural or fanned ventilation, toss it out do not cover!, scrub with detergents (don’t mix bleach and ammonia as produces toxic gas)
Correct generator usage
Outdoors, away from windows or doors and instal a CO-detector.
Occupational health hierarchy of controls (6 steps)
First substitute, then engineer, next administrate, then train, lastly use PPE and monitor.
Issues of veterinary occupational safety
musculoskeletal issues, safety culture, hazardous drugs and chemicals, infectious diseases and zoonotic diseases, sharps, mental health, injuries caused by animals, extreme weather conditions, noise, respiratory and reproductive hazards
Why is molybdenum of interest to veterinarians?
Ruminants get molybdenosis - ie secondary copper deficiency which shows as diarrhoea, depigmentation and pica for example. Copper and sulfates both play a role in it’s development.
Blood lead level limit
5 micrograms per deciliter (lowered from 10, lead levels across us falling, so might be lowered more)
How can you prevent lead leaching to drinking water from pipes?
With the use of corrosion control, ie adding orthophosphate to water that will forms a protective coating of insoluble mineral scale on the inside of service lines and household plumbing
What water contaminants can you reduce with water filtration?
Asbestos, Lead, Mercury Atrazine, Benzene, Carbofuran, Chlorobenzene, Cyst, Endrin, Ethylbenzene, Lindane, MTBE, O-Dichlorobenzene, P-Dichlorobenzene, Tetrachloroethylene, Toxaphene, Turbidity, Volatile organic compounds
Steps for foreign animal diseases response.
- Detection and confirmation of a disease
- Determine a method and carry out euthanasia
- Carcass disposal
- Clean and disinfection of the premise
- Environmental sampling
Name the primary agencies responsible for international animal health and U.S. animal health
USDA APHIS (animal plant health inspection service) Veterinary Services
what agencies are responsible for the importation of animals
FDA, HHS, CDC, USDA, and US Fish and Wildlife Service
