Ecotoxicological combined effects from chemical mixtures Part 1: Relevance and adequate consideration in environmental risk assessment of plant protection products and biocides
- 2014
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- The Project deals with the possibilities of performing mixture toxicity assessment within the environmental risk assessment of the authorization of biocide and plant protection products. To this end a review on the state of scientific knowledge about the predictivity of combined effects is collated. Central in this context is the reference model of Concentration Addition which allows extrapolating combined effects for mixtures based on knowledge about the effects of the components. Building on this, options for risk regulation are developed. Their applicability is considered in the context of those data that are currently available within the authorization process for biocide and plant protection products. Deficits with respect to a – scientifically sensible – homogeneous data base can often be overcome with pragmatic decisions if additional requirements for the authorization process are not an option. Tiered schemes to specifically account for combined effects during environmental risk assessment of biocide and plant protection product authorization are suggested, accompanied with a software tool for its implementation.

Books on Screens : Players in the Swedish e-book market
- 2017
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- The music and film industries have long come to terms with the digital, and now the traditional printed book is challenged by digital formats. The e-book has become established in most countries, but is still a small part of the book industry. In this book a group of researchers follow the actors involved in the Swedish e-book market, from authors and publishers to libraries, booksellers and readers during 2012-2016. Using surveys, interviews and other sources the main actors were researched and it is shown how they act and react towards the e-book and towards each other. While the main focus in on Sweden as a small language country, several international comparisons are made. Are printed books disappearing soon? How are reading habits changing when the book becomes digital? Which forces are driving radical change and which are holding it back? The book discusses these and related questions and shows that after a period of rapid increase in the production and use of e-books, several factors slow down the rate of adoption, but digitisation of the book is an ongoing process and the current e-book is not the end of the story.
