New article in Science of the Total Environment by Dr Tim Sullivan and Hannah Binner!
MESA Principal Investigator, Dr Tim Sullivan, and PhD candidate, Hannah Binner, have, along with Prof Mairead Harding and Dr Naghmeh Kamali of the Oral Health Services Research Centre (Cork University Dental School & Hospital), co-authored a new publication, entitled Characteristics of wastewater originating from dental practices using predominantly mercury-free dental materials. The study examines the composition and characteristics of wastewater from dental streams, and analyses the ecotoxicity, particulate load and overall risk from this understudied source of environmental contamination. This article addresses a knowledge gap, and highlights central findings that include the presence of micro- and nanoscale particles in dental wastewater, suggesting dental wastewater could act as a pathway for nanoparticles to enter the environment, and an EC50 (48h, D. magna) of as little as 0.2 mL/L of dental wastewater.
