Ethics and Responsibility in Science 2 Flashcards
(36 cards)
When trying to understand the chemical impact of a process, what might we try to consider?
- The Sustainable Development Goals
- The abundance of the 90 natural elements which make up everything - finite supply?
- Energy?
- Geographical distribution
- Stability of supply
- Influence
What does the sustainability of energy production depend upon?
- Geographial control of supply/influence and impact
- Stability of supply
- Air miles
- Multiple impacts on SDG and environment
- Demand on elements required to give us this technology BUT reduce demand for elements previously used to give combustion (i.e. Pt in catalytic converters)
What does the transtition towards renewable depend on
- Infrastructure available
- Availability of metals like Cd, Nd, Si etc for batteries
- Displacement of risk,e.g. recent example in spain of everything stopping due to a power cut
- Storage and distribution networks - Smart Grids
What is a small nuclear reactor (SMR)
- It is a small modular reactor (SMR) which is a compact nuclear power station designed to be more flexible, cost-effective, and quicker to deploy than traditional large nuclear reactors (470 mW vs 1000 mW)
What does the sustainability of the small nuclear reactor depend on?
- Are decisions based upon science and data?
- Displacement?
- Risk vs Reward?
- Green or Sustainable - No discharge to atmosphere/environment (smoke, dust, ash)
- Staggering energy yield - but is it all good?
Why is decision making in Chemistry a complex process?
- Metric systems tend to emphasis one specific facet of a process, multiple metrics must be used to build a picture of the relative interactions and impacts - Planetary boundaries as an example
- Multi-impacts - require complex network analysis - LCA - all are retrospective and require data, often large data to inform choice
What are the nine planetary boundaries?
- Climate Change
- Freshwater Change
- Stratospheric Ozone depletion
- Atmospheric Aerosol loading
- Ocean Acidification
- Biogeochemical flows
- Novel entities (stuff being produced by us, plastics etc)
- Land-system change
- Biosphere integrity
What is the purpose of the nine planetary boundaries?
- It is a multifaceted domain based approach
- Some domain are currently quantifiable - others not
- Evaluated impacts of complex linked systems
- BUT can take years for the impact to evolve or to be measured
How have the planetary boundaries changed since 2009-2015?
The decipline you are based within can define…
… the optics through which we identify and recognise challenges
A report called ‘On Being a Scientist: A Guide to Responsibility Conduct in Research’ - USNAS, 2009, speaks upon the scientific enterprise being built on a foundation of trust, why?
- ‘Appropriate analytic and statistical techniques, have reported their results accurately, and have treated the work of other researchers with respect’
- ‘Misplaced trust… would impact the relationship between science and society’
What can ethics in science dictate?
- Motivation, honest, integrity, and economic gain
The Nolan Principles of Public Life are 7 principles all olders of public office should adhere to, defined by the Nolan Committee
What are they?
- Selflessness
- Integrity
- Objectivity
- Accountability
- Openness
- Honesty
- Leadership
Ethics for scientists can include: Rigour, Respect and Responsibility
Define each aspect…
- Rigour: Act with skill/care, keep skills up to date; prevent corrupt practice & declare conflicts of interest; respect + acknowledge the work of other scientists
- Respect: Ensure that reasearch is justified/lawful; minimis impacts on people, animals + environment
- Responsibility: Discuss issues sceince raises for society; Do not mislead + present evidence honestly
What are Neonicotinoids
They molecules defeat bugs eating the shoots of oil seed rape, which therefore increase the viability of seed germination
What are some benefits of neonicotinoids?
- Neonictinoids most often applied to the soil and are translocated through the entire plant
- Variety of appliation methods: soil drench, irrigation, seed treatment, tree injection
- Safer to mammals and birds (selective-binding to insects)
What are some disadvantages of Neonictinoids?
- Neonicotinoids most often applied to the soil and are translocated to pollen and nectar
- Harmful against all benefical insects eating pollen/nectar
- Long lasting residual effects in pollen, nectar, leaves, soil
- Bayer argues 20 ppb imidaclorpid will not affect mortality, but will affect behavoir
- However farmers will apply more believing the better the crop yeild - however increases the amount of runoff
What did the use of Neonicotinoids cause?
- Declines in the Bee populations
- The registration of the chemical was based on a Bayer study which was later found by beekeepers to be deficient and later EPA argreed
- Insecticide seed coating dust extremely toxic to bees deducted in new studied (EFSA, 2013)
- Insecticides used contributed to weakened immue systems, increased susceptibility to pathogens
How does the use of Neonicotinoids relate to the Triple bottom line
- Meets the economic goal due to increased productivity of fields for food production
- Meets the social goal of food production
- However ignored the planetary tension here through affecting pollinator populations
Neonicotinoids were then banned
What was the unintended consequences of this?
- Rising prices of cooking oils are the productivity of rape seed oil was now reduced
- Farmers were having to use 3x the amount of seed for the same amount of oil production
What did the Paracelsus (1493-1541) say about toxicology?
“The dose makes the poison”
What is the equation for risk
How does green chemistry suggest we reduce risk?
By minimising the hazard, the risk becomes zero
How does responsible research and innovation link to risk?
Approach needs to be foward looking rather than reterospective
And this requires the prior identificaton of risk (i.e. identification of the risk to bees with neonictinoids)
