Toxicity and Assessment of Chemical Mixtures

Toxicity and Assessment of Chemical Mixtures
Arden Jansen

Current risk assessment for people, animal and plants are usually carried out one at a time when talking about exposure to multiple chemical substances. Many associations such as the EFSA, have been taking a deeper look into this topic. This research has been happening because of the challenges it poses for the Authority’s scientific work. This is not one of the first steps in this field for the EFSA, they have taken multiple steps into risks of pesticides for liking things and mixtures of contaminates for humans. With this being said, this is just one of many company's exploring this topic. 
The current risk assessment is basically taking a closer look into how multiple chemicals when made into a mixture can harm us. Not only can It harm us, but it can also harm other living things such as bees. Surprisingly enough, non-toxic concentrations may result in a significant amount of toxicity. This research will not only help us but other living things you may not think about such as bees. 
One of the first steps that the EFSA is taking to assess it is to identify chemical mixtures of priority of risk. They will do this by using criteria for a risk-based approach that will use the toxicity of the chemicals concerned as well as the estimated exposure to them. This is often hard to find data because there are limited amounts of it out there. Due to this, it makes the testing tricky because of the adverse effects on organs and/or other phycological systems. This research can become possible because of the new tools. 
There will be many steps that will be taken in the future. As I mentioned before, this is just the start to many new innovated designs and intelligent scientist in this field. I think that when they have the basics figured out, they will take it to a whole new extreme technology wise. There will be technology that can scan the mixture an detect the toxicity and simulate it if it were to go inside a living organism.

Mahar-ullah Shahminah- Molecular Gastronomy

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
