I'm currently exploring the negative effects of PBDEs on freshwater mussels and fish. Next are microplastics.

Introduction
My field of research is environmental toxicology. I have a special interest in pollution responsive biomarkers (histological, biochemical) for their use in environmental risk assessment and monitoring programs. My test organisms are fish and mussels, and I'm currently working with heavy metal and POPs (pesticides, polyaromatic hydrocarbons) contamination of freshwater ecosystems and its negative effects on biota.

Question
I am about to apply the LMS (lysosomal membrane stability) method on mussels and following the protocol I need HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid). However, the companies in my country don't have it in stock and they need 4 weeks to get it. I need it for my experiment by the end of this month. Do you have any idea if I can use another buffer instead of HEPES? Thank you!!!
Question
I would like to know more about other national allowable heavy metal levels in fish.
I am familiar with:
- COMMISSION REGULATION (EC) No 629/2008 of 2 July 2008 amending Regulation (EC) No 1881/2006 setting maximum levels for certain contaminants in foodstuffs; 
- Joint FAO/WHO food standards programme codex committee on contaminants in foods, Fifth Session, The Hague, The Netherlands, 21-25 March 2011; and
- Australia/New Zealand Food Standards Code (2013)
but couldn't really find information for example about Scandinavian, Turkish or Canadian regulations and recommendations. Thanks.
Question
Two marine species - Mytilus edulis and Mytilus galloprovincialis are the most common ones, which are used in ecotox research on the effects of water contamination. I was wondering which freshwater mussels can be successfully applied in such studies instead of the marine species? Thanks a lot.
