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.
