This new Framework provides regulators with a consistent and transparent approach for reviewing the use of (Q)SAR predictions in a regulatory context and increases the confidence to accept alternative methods for evaluating chemical hazards. The OECD worked closely together with the Istituto Superiore di Sanità (Italy) and the European Chemicals Agency (ECHA), supported by a variety of international experts to develop a checklist of criteria and guidance for evaluating each criterion. The aim of the QAF is to help establish confidence in the use of (Q)SARs in evaluating chemical safety, and was designed to be applicable irrespective of the modelling technique used to build the model, the predicted endpoint, and the intended regulatory purpose.
The webinar provided an overview of the project and presented the main aspects of the framework for assessing models and results based on individual or multiple predictions.
There is a tremendous amount of news being disseminated every day online about dangerous forever chemicals called PFAS. In this interview with a global PFAS testing expert, Geraint Williams of ALS, he and York Analytical President Michael Beckerich discuss the hot-button issues for the environmental engineering and consulting industry -- the wider range of PFAS contamination sites, new PFAS that are unregulated, and the compliance challenges ahead.
Widespread PFAS contamination requires stringent sampling and laboratory analyses by certified laboratories only -- whether it is for PFAS in soil, groundwater, wastewater or drinking water.

Trichogramma spp. is an efficient egg parasitoids that potentially assist to manage the insect-pests from the field condition by parasiting the host eggs. To mass culture this egg parasitoids effectively, we need to culture another stored grain pest- Rice Meal Moth (Corcyra Cephalonica). After rearing this pest, the eggs of Corcyra will carry the potential Trichogramma spp., which is an Hymenopteran Wasp. The detailed Methodologies of rearing both Corcyra Cephalonica and Trichogramma spp. have described on this ppt.
Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.
4. Renewable Energy
• Maine is endowed with plentiful bioenergy,
wind, hydropower, ocean, and other
renewable energy resources.
• Non-hydro renewables are responsible for
32% of in-state generation, a higher
percentage than in any other state in the
nation.
5. Renewable Energy
• Maine is home to the country’s first tidal
energy device to generate electricity for the
power grid and first working offshore wind
turbine (as of 2014).
6. Solar Energy
We use solar thermal energy systems to
• heat water for use in homes, buildings, or swimming pools
• heat the inside of homes, greenhouses, and other buildings
• heat fluids to high temperatures in solar thermal power plants
Solar photovoltaic devices, or solar cells, change sunlight
directly into electricity.
8. Solar Energy
The two main benefits of using solar energy are
• Systems do not produce air pollutants or carbon dioxide.
• Systems on buildings have minimal impact on the environment.
The main limitations of solar energy are
• The amount of sunlight that arrives at the earth's surface is not constant.
The amount of sunlight varies depending on location, time of day, season
of the year, and weather conditions.
• The amount of sunlight reaching a square foot of the earth's surface is
relatively small, so a large surface area is necessary to absorb or collect a
useful amount of energy.
9. Wind Energy
• Wind turbines operate on a simple principle. The energy in
the wind turns two or three propeller-like blades around a
rotor. The rotor is connected to the main shaft, which spins a
generator to create electricity.
11. Wind Energy
• Wind turbines are mounted on a tower to
capture the most energy. At 100 feet or more
above ground, they can take advantage of
faster and less turbulent wind.
• Wind turbines can be used to produce
electricity for a single home or building, or
they can be connected to an electricity grid for
more widespread electricity distribution.
12. Wind Energy
• Advantages of Wind Energy
– Clean and renewable source of power
– Cost effective
– Rapid growth of industry, large potential
• Disadvantages of Wind Energy

13. Tidal Energy
• Tidal Stream Generator
– Makes use of the kinetic energy of moving water to power turbines, in
a similar way to wind turbines that use wind to power turbines.
• Tidal Barrage
– Tidal barrages make use of the potential energy in the difference in
height between high and low tides.
14. Tidal Energy
• Advantages

• Disadvantages
– Tidal power can have effects on marine life.
• The turbines can accidentally kill swimming sea life with the
rotating blades.
• Some fish may no longer utilize the area if threatened with a
constant rotating or noise-making object.
• Installing a barrage may change the shoreline within the
bay or estuary, affecting a large ecosystem that depends on tidal
flats.
15. Wave Energy
• Ocean waves contain tremendous energy
potential.
• Wave power devices extract energy from the
surface motion of ocean waves or from
pressure fluctuations below the surface.
16. Wave Energy

– Visual/noise issues
17. Geothermal Energy
• (geo = earth and thermal = heat), geothermal
energy comes from heat produced by the
Earth.
18. Geothermal Energy
• Direct geothermal energy can be accessed in areas where hot
springs/geothermal reservoirs are near the surface of the
Earth.
• Geothermal heat pumps utilizes a series of underground
pipes, an electric compressor and a heat exchanger to absorb
and transfer heat.
• Geothermal power plants also harness the heat of the Earth
through hot water and steam. In these plants, heat is used to
generate electricity.
19. Geothermal Energy
• Advantages
– Renewable energy
– Cleaner than burning fossil fuels
• Disadvantages
– Cost of drilling, researching proper areas
– Requires a suitable location
20. Biofuels
• The two most common types of biofuels
are ethanol and biodiesel.
21. Biofuels
– Ethanol is an alcohol.
– Ethanol is mostly used as a fuel additive to cut
down a vehicle's carbon monoxide and other
smog-causing emissions.
22. Biofuels
• Biodiesel is made by combining alcohol
(usually methanol) with vegetable oil, animal
fat, or recycled cooking greases.
• It can be used as an additive to reduce vehicle
emissions (typically 20%) or in its pure form as
a renewable alternative fuel for diesel
engines.
23. Biofuels
• Advantages
– Easy to source
– Renewable
– Reduces greenhouse gases
– Reduced dependence on foreign energy
• Disadvantages
– Higher cost of production (lower supply than gasoline)
– Monoculture
– Shortage of food
– Water Use
Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, tides, waves and geothermal heat. Waste-to-energy and anaerobic digestion are also done, but not discussed in detail here.
Waste – to – energy – Using waste as an energy source to generate electricity or heat; it is also a waste reduction method.
Anaerobic Digestions (biogas) - Anaerobic digestion is a biological process that produces a gas principally composed of methane (CH4) and carbon dioxide (CO2) otherwise known as biogas. These gases are produced from organic wastes such as livestock manure, food processing waste, etc and these gases can be used for process heating or electrical generation.

Photo Top Left – Solar Tower - The Sun’s light is focused onto a small area using mirrors. The mirrors constantly follow the Sun as it moves through the sky. They do this to make sure they are receiving as much light as possible.
The beam created by all of these reflecting mirrors is used to heat a liquid to an extremely hot temperature—sometimes over 1000°F! This liquid is a chemical that is very good at trapping heat. After it is heated, the liquid is pumped through a tank of water in a pipe. These hot pipes cause the water to boil and create steam. This steam spins a turbine, which powers a generator. Sometimes, the hot liquid itself is used to power the generator.

The world's first large-scale tidal power plant was the Rance Tidal Power Station in France, which became operational in 1966
Tidal Stream Generator - Some tidal generators can be built into the structures of existing bridges or are entirely submersed, thus avoiding concerns over impact on the natural landscape.
Tidal Barrage - When using tidal barrages to generate power, the potential energy from a tide is seized through strategic placement of specialized dams. When the sea level rises and the tide begins to come in, the temporary increase in tidal power is channeled into a large basin behind the dam, holding a large amount of potential energy. With the receding tide, this energy is then converted into mechanical energy as the water is released through large turbines that create electrical power through the use of generators.
There are other types tried as well…
https://en.wikipedia.org/wiki/Tidal_power Photo: tidayenergytoday.com,
Disadvantages - Inhibiting the flow of water in and out of the bay, there may also be less flushing of the bay or estuary, causing additional turbidity (suspended solids) and less saltwater, which may result in the death of fish that act as a vital food source to birds and mammals. Migrating fish may also be unable to access breeding streams, and may attempt to pass through the turbines. The same acoustic concerns apply to tidal barrages
https://en.wikipedia.org/wiki/Tidal_power

Several types are shown….
Photos: Ocean Power Technology's (OPT) Powerbuoy wave generation system (left) A point absorber is a floating structure with components that move relative to each other due to wave action (e.g., a floating buoy inside a fixed cylinder). Point absorbers often look like floating oceanographic buoys. They utilize the rise and fall of the wave height at a single point for energy conversion. The relative up and down bobbing motion caused by passing waves is used to drive electromechanical or hydraulic energy converters to generate power.
Right - The Agucadoura Wave Farm offshore Portugal was the world's first. It was tested and operated in 2008. 3 miles offshore, using the Pelamus Wave Energy Conversion Device. Attenuators are long multisegment floating structures oriented parallel to the direction of the waves. They ride the waves like a ship, extracting energy by using restraints at the bow of the device and along its length. The differing heights of waves along the length of the device causes flexing where the segments connect. The segments are connected to hydraulic pumps or other converters to generate power as the waves move across.
Beneath the surface (or crust) of the Earth, there are a number of heat-producing layers of rock, minerals, and magma, including the mantle, the outer core, and the inner core. The deeper you dig towards the center of the Earth, the hotter it gets. In fact, the core (about 4,000 miles beneath the surface), can reach temperatures of 7,600 degrees Fahrenheit.
This heat – which can be harnessed for energy — is caused by residual heat from the formation of the Earth, as well as decay of radioactive isotopes.

Direct geothermal energy - . In these areas, hot water (pumped through a heat exchanger) can be directly piped in to heat homes or buildings. The “used” water is then returned to the reservoir for re-heating.
Geothermal heat pumps - In the summer, the system removes heat from the house/building and returns it to the Earth. In the winter, the geothermal pump absorbs heat from the ground and transfers it into the house/building.
Geothermal Power Plants – There are several different kinds of power plants.

The two most common types of biofuels are ethanol and biodiesel.
Ethanol is an alcohol, the same found in beer and wine. It is made by fermenting any biomass high in carbohydrates (starches, sugars, or celluloses) through a process similar to brewing beer. Ethanol is mostly used as a fuel additive to cut down a vehicle's carbon monoxide and other smog-causing emissions. But flexible-fuel vehicles, which run on mixtures of gasoline and up to 85% ethanol, are now available.

Advantages of Biofuels
Cost Benefit: As of now, biofuels cost the same in the market as gasoline does. However, the overall cost benefit of using them is much higher.
Easy To Source: Biofuels are made from many different sources such as manure, waste from crops and plants grown specifically for the fuel.
3. Renewable: Since most of the sources like manure, corn, switchgrass, soyabeans, waste from crops and plants are renewable and are not likely to run out any time soon, making the use of biofuels efficient in nature. These crops can be replanted again and again.
4. Reduce Greenhouse Gases: Fossil fuels, when burnt, produce large amount of greenhouse gases i.e. carbon dioxide in the atmosphere. These greenhouse gases trap sunlight and cause planet to warm. The burning of coal and oil increases the temperature and causes global warming. To reduce the impact of greenhouse gases, people around the world are using biofuels. Studies suggests that biofuels reduces greenhouse gases up to 65 percent.
5. Economic Security: If more people start shifting towards biofuels, a country can reduce its dependance on fossil fuels. More jobs will be created with a growing biofuel industry, which will keep our economy secure.
6. Reduce Dependence on Foreign Oil: As prices of crude oil is touching sky high, we need some more alternative energy solutions to reduce our dependance on fossil fuels.
7. Lower Levels of Pollution: They release lower levels of carbon dioxide and other emissions when burnt. Although the production of biofuels creates carbon dioxide as a byproduct, it is frequently used to grow the plants that will be converted into the fuel. This allows it to become something close to a self sustaining system.
Disadvantages of Biofuels
High Cost of Production: Even with all the benefits associated with biofuels, they are quite expensive to produce in the current market.
Monoculture: Monoculture refers to practice of producing same crops year after year, rather than producing various crops through a farmer’s fields over time..
3. Use of Fertilizers: Biofuels are produced from crops and these crops need fertilizers to grow better. The downside of using fertilizers is that they can have harmful effects on surrounding environment and may cause water pollution. Fertilizers contain nitrogen and phosphorus. They can be washed away from soil to nearby lake, river or pond.
4. Shortage of Food: Biofuels are extracted from plants and crops that have high levels of sugar in them. However, most of these crops are also used as food crops. Even though waste material from plants can be used as raw material, the requirement for such food crops will still exist. It will take up agricultural space from other crops, which can create a number of problems. Even if it does not cause an acute shortage of food, it will definitely put pressure on the current growth of crops. One major worry being faced by people is that the growing use of biofuels may just mean a rise in food prices as well.
5. Industrial Pollution: The carbon footprint of biofuels is less than the traditional forms of fuel when burnt. However, the process with which they are produced makes up for that. Production is largely dependent on lots of water and oil
6. Water Use: Large quantities of water are required to irrigate the biofuel crops and it may impose strain on local and regional water resources, if not managed wisely.
7. Future Rise in Price: Current technology being employed for the production of biofuels is not as efficient as it should be. Scientists are engaged in developing better means by which we can extract this fuel.
